Microsoft SharePoint is a web-based application that is amalgamated with Microsoft Office suite. Microsoft Corporation first launched SharePoint in 2001 as a document management and storage system. In organizations, it's commonly used to create websites. According to a survey, SharePoint has 160 million users across 75,000 customer organizations.

SharePoint can be used as a secure place where users can store their critical data and information. Also, it allows users to access, organize and share the information with almost all types of devices. A web browser is the only thing required here, be it Internet Explorer, Google Chrome or Firefox. SharePoint is available in various editions for different functions, such as SharePoint Server, SharePoint Standard, SharePoint Enterprise, and SharePoint Online. Here in this article, we'll talk about SharePoint Server.

Microsoft SharePoint Server is a popular server platform commonly used for information sharing, collaboration, and content management. It provides vast benefits for organizations, such as:

  • You can create an intranet portal for your organization in order to share information.
  • You can manage and edit documents among multiple users and offices.
  • Also, you can create a public-facing website.

The major capabilities of SharePoint Server are collaboration, enterprise content management, enterprise search, and building portals. Although the benefits of SharePoint Server are vast, but it has a major drawback. It has many internal bugs which can cause some issues sometimes. Also, the database file created by SharePoint Server is highly prone to corruption just like any other database file. Below are the most common reasons for corruption in SharePoint Server:

  • If SharePoint Server has low RAM or hard disk space, you may be at high risk. It may cause a crash in SharePoint Server or corrupt the database file.
  • Using virtual Microsoft SQL Server can also create problems for SharePoint Server users. Improper virtualization allows administrators to make big mistakes which may result in corruption.
  • During the creation of content web apps, fully qualified URLs are primarily required. But if you use incorrect or short URLs, it may cause serious problems.
  • Enabling the default settings for the SharePoint database might be risky. For example: if the Autogrow setting is enabled, it'll grow the database file size by 1 MB with every upload. Such action can slow down SQL Server as well as SharePoint.
  • SharePoint can store a large number of PDF files containing valuable information. SharePoint Search allows you to access the information stored in PDF files. Make sure you've installed iFilter only for those SharePoint Servers which run the Search Index role. But if you're not using any “PDF iFilter”, it might be harmful to you.
  • If you've disabled BLOB caching, you may face some serious issues. BLOB caching plays a very important role in SharePoint and improves its performance.

If you've taken a backup of SharePoint Server, you can restore it with ease. But if there's no backup, you should try to repair SharePoint database manually. There's a feature in SharePoint Server 2010 to restore the configuration database. This will help you restore the farm configuration. In SharePoint Server 2013 and 2016, you can directly restore farm configuration without restoring the configuration database.

Follow the steps to know how to repair SharePoint database:

  • Go to the Central Administration's home page. On “Backup and Restore” section, click “Restore from a backup”.
  • Choose “Backup to Restore” page on “Restore from Backup” screen. Select the backup job and click Next to continue the process.
  • Now choose “Component to Restore” page, and click the check-box shown next to the farm. Click Next to continue the process.
  • On “Restore Component” section, select Restore Options page from “Restore from Backup” option. Note – Make sure the Farm appears in Restore the following content listing.
  • On “Restore Only Configuration Settings” part, select “Restore content and configuration settings preference”.
  • On “Restore Options” section, select “Type of Restore preference”. You need to use Same configuration settings. Click OK to confirm this operation. Then click Start Restore option.

Before you can use the above manual trick, make sure:

  • You must be a member of the Farm Administrators group on the system running Central Administration.
  • You're having the permissions for a sysadmin server role on the database server which contains all the databases.

Reasons for Corrupt SQLite Database – SQLite Database Recovery

SQLite is a popular relational database management system excessively used in these days. But unlike other database management systems, it's not a client-server database engine. In fact, it's embedded into the end program. SQLite is widely supported by various browsers, operating systems, embedded systems and many other applications. If you want an open-source and embedded…

SQLite is a popular relational database management system excessively used in these days. But unlike other database management systems, it's not a client-server database engine. In fact, it's embedded into the end program. SQLite is widely supported by various browsers, operating systems, embedded systems and many other applications. If you want an open-source and embedded database program for local / client storage in application software, you must use SQLite.

Just like other database programs, SQLite also creates a database file. Since it's an open-source program, it does not use any specific file extension. Sometimes corruption can cause sever issues and put SQLite data at high risk. We all know that database files are highly prone to corruption due to its large size and complicated file structure. Like any other file, the SQLite database file is not immune to corruption. There are various reasons which cause corruption, and you must know them. If you're aware of the most common reasons of corruption, you can take the correct measures to avoid them.

  • Although file locking problem looks normal, but sometimes they can cause some damage. SQLite uses file lock system for the database file as well as WAL (Write-Ahead Logging) file. The primary function of the file lock system is to coordinate access between concurrent processes. Sometimes, two threads or processes may cause incompatible changes to a database file without proper coordination.
  • SQLite database is actually an ordinary disk file. This means any process can easily open it and overwrite it with junk characters or make unwanted changes. Any bad thread or process can cause such an appropriate action with ease, even SQLite library can not help you in this situation.
  • If any failure occurs in the disk drive or flash memory, this can corrupt SQLite database. This can cause changes or alteration in the file content, and lead to corruption.
  • SQLite has many built-in protections which work against database corruption. But sometimes, many of these protections are disabled due to configuration options. This will result in corruption in SQLite database files.
  • Almost all programs contain some internal bugs. The SQLite database program has some minor bugs which may cause corruption.

Corruption makes SQLite database inaccessible. In such situation, you have three options:

  1. Valid backup for the database
  2. Manual trick to repair SQLite database
  3. Professional SQLite database recovery solution

If you're having a valid backup, you can easily restore SQLite database from it. But if you do not have any backup, you should try to repair SQLite database manually. If you're using SQLite database browser, you just need to follow these simple steps:

Step 1: Launch DB Browse for SQLite on your system. Click Execute SQL tab in order to run database check command.

Step 2: Type this command – PRAGMA integrity_check , and click the play button.

Note: Since the database is corrupt, you would see an error message (s).

Step 3: So now you should try to export the database into SQL file. Click File tab on top > Export > Database to SQL file .

Step 4: On Export SQL dialog box, select the objects you want to export. You can define other options as well.

Step 5: You can start the process by clicking OK . Please wait until the process is completed.

Step 6: After that, you can import the database back to SQLite browser. Click File tab on top > Import > Database from SQL file .

You can now check your database. It's fine now. Or if corruption is still there, you should use a professional recovery solution. There are many software vendors in the market which provide such recovery solutions with free demo / trial version. Typically, demo / trial version is used for the free evaluation purpose. If you use demo / trial version, you can see what you could recover from the corrupt database file before you can actually pay for the software.

Considerations for Large-Scale AWS Migration

Managed IT services providers recommend virtualization not because it is an IT business trend that everyone simply must ride, but because it is, quite, a smart way of managing your IT resources. Every day, more and more organizations migrate to the Amazon Web services public cloud. However, despite the cloud's benefits in scalability, agility and…

Managed IT services providers recommend virtualization not because it is an IT business trend that everyone simply must ride, but because it is, quite, a smart way of managing your IT resources. Every day, more and more organizations migrate to the Amazon Web services public cloud. However, despite the cloud's benefits in scalability, agility and efficiency, they discover a new set of challenges that need to be overcome.

Gartner estimates that more than 50 percent of enterprises will have adopted a hybrid cloud approach by this year. Transitioning from a traditional on graduation IT infrastructure to a public cloud can be overwhelming and success requires a different mindset and range of skills. Here are a few points that you should consider when moving to the AWS cloud.

1. Preparation for migration: Some points that you need to consider when preparing for the large scale migration are – if everyone within the organization on board with this major move? Are your employees adequately equipped with knowledge about the cloud? And, since large-scale transfers involve big data, would your security framework be able to deal with potential security threats during the transition? Can your company handle the inevitable expenditure that goes with investing in the cloud?

2. Reasons for migration: You as a business owner, should have a clear understanding of the reason for migrating to the cloud and the importance of it. The most compelling reason is the need to meet your business's increasing demand for efficiency, that would lead to greater profitability. Other reasons could include change of organizational leadership or a shift in business structure that necessitates storage recalibration.

3. Cloud Finances: Different organizations have different financial approaches, and their choices of IT infrastructure reflect this fact. For some, the on-premise approach of making a large, upfront capital expenditure to purchase infrastructure and then capitalizing the investment over time may be the preferred option because they prefer to keep complete control over their IT environment. However, for others, a heavy initial expense is not ideal, so a cloud approach with only ongoing, operational costs is more fitting. This option may be particularly suitable for organizations with fluctuating needs on a monthly basis, as an on-premises data center will not offer them the flexibility they require. Regardless of the approach, it is important to compare the proportional costs before deciding which one is most suitable. The best option may be to combine both on-premise and cloud to create a hybrid cloud environment. This will allow for steady workloads to be kept onsite while bursts in demand can be processed by an on-demand, public cloud.

4. Security and Availability: The idea of ​​handing over all of your data to a public cloud provider can be a daunting because of the obvious security and availability concerns. However, public cloud providers must adhere to strict compliance protocols and can implement and maintain much higher security levels than on-premise installations because they have more available resources.

5. Migration requirements: While migrating to the cloud you need to have every tiny details in place like, which specific data, servers, or applications need to be migrated? Does your company need large-scale migration, or can it survive on moving only a small part of your resources to the cloud? Perhaps, a subsidiary could survive without having to be moved to the cloud.

6. Beware of Staff Apprehension: Any dramatic change within an IT environment will face staff apprehension. You may expect the shift to be met with resistance from corporate management, but the real doubts will come from your IT team. After working with on-premise infrastructure for years, administrators will not welcome any changes they think could jeopardize their jobs. Help your team embrace this shift by making sure they receive qualified training to prepare them for a new set of challenges.

7. Log Analysis and Metric Collection: Organizations moving to AWS suddenly find themselves managing a highly scalable and highly dynamic environment that requires a new type of log analytics and metric collection. The need for centralization of data is critical in dynamic environments because often you find yourself trying to troubleshoot a problem on servers that no longer exist.

8. Impact to the business: Temporary downtime is something you have to be ready for. You might need more time or you might need to consider alternatives for the brief interruptions that come with migration, and of course budget can be a major factor in your decision to move. You can save your business from unnecessary obstacles by first assessing its ability to handle these situations.

AWS is the preferred public (IaaS) cloud choice for enterprises today, and it looks set to stay this way. To achieve a successful transition during a migration of workloads and products to AWS, the process needs to be carefully planned and implemented in a step-by-step fashion that will prove the benefits of the move to all of the quakeholders.

Do’s and Don’ts of Data Loss

Data corruption is certain to cause a lot of chaos and panic. With the right steps taken, it is possible to recover lost data from a laptop or PC.

Data corruption is certain to cause a lot of chaos and panic. With the right steps taken, it is possible to recover lost data from a laptop or PC. In many situations where the hardware is still active, there are several options to recover the potentialally lost data yourself. But, if the hard drive appears to be mechanically damaged, the only cause of action is to send it to the professionals to repair.

Here are a few do's and don'ts of data loss:

Do's

Do make contact with the professional if you are not entirely sure of what is needed to recover the data. For those with a backup machine, it is possible to research and learn the basics of data loss recovery before attempting any work on the damage PC.

But for those that are not experienced with working with computers, it may be more practical to seek the guidance of a professional, especially for machines that hold a lot of important or sensitive information.

Do look for a data recovery tool online and use the free trial or demo version to see if the lost data is still available for recovery. If the trial appears to be successful, it is worth investing in the full software tool to get the data back.

Do attempt to save the data onto a backup or external drive to check file system integrity and readiness. In many situations it is possible to copy the data if the issue only relates to a corrupted operating system.

Make sure to regularly back up the critical files, photos, or other data that will cause difficulties if if lost.

Don'ts

Do not attempt to load up recovery software on the partition or drive that experienced the lost files. This will likely overwrite the existing information and make it impossible to recover.

It rarely benefits to simply attempt to swap the existing circuit board on the modern drives. There is the risk of system or firmware conflicts that can lead to even more difficulties.

Do not be tempted to open up the laptop or PC to take a look at the hard drive and related components. There is not much that can be done by the do-it-yourselfer in this situation. It is best to pass the computer to a skilled data recovery engineer who is qualified to repair the hardware and works in a safe clean room environment.

In the event of any data loss issue, it is important to stay calm and carefully consider the options to avoid making things worse and not being able to do anything to recover the files on the PC.

How to Find the Best Data Recovery Software for You

Selection of the best data recovery software is critical if you want to ensure a successful recovery of your lost data. But, the problem that people face when looking out for the best software is “they read product reviews.” Maximum of such reviews are paid; therefore, they are product centric.

Selection of the best data recovery software is critical if you want to ensure a successful recovery of your lost data. But, the problem that people face when looking out for the best software is “they read product reviews.” Maximum of such reviews are paid; therefore, they are product centric. In many reviews, you will not even see a single “flaw” of the software. How it is possible that the software does not have even a single fault? Was that designed and developed by a team of angles? So, you need to be aware of such paid reviews when looking out for an efficient software to recover the lost data.

In this article, I will take you through some steps that can help you find the best solution help you recover the lost data from Windows or Mac machines. In addition to Windows and Mac, you will be able to perform data recovery on pen drives, memory cards, cameras, etc.

Best Method to Find a Perfect Data Recovery Tool

First of all, you need to forget all reviews. You do not need to stick to any specific brand as well. You should rather inspect the functioning of the tool, its simplicity, and its accuracy. So, let's start finding a good solution to perform flawless data recovery.

Step 1 – Start a Web browser.

Step 2 – Open Google or Bing.

Step 3 – Type “Data Recovery software companies” in the search bar.

Step 4 – Visit websites of a few companies in separate tabs.

Step 5 – Download the trial versions of the software of the different companies.

After this, we need to prepare a setup to test these trial versions. Before we go ahead, I would like to mention that “the free trial versions of these software” work similar to the paid versions, but you are not allowed to save the recovered data. You can check the worth of the recovered data, but to that a license will need to be purchased.

Caution

Do not use the free trial version on the device from which you want to recover the lost data, because if it does not work well, you may not be able to get back the lost data even with another tool. That's why, after Step 5 above “I mentioned the need to prepare a setup.

Preparing Setup for testing the Best Data Recovery Software

  • Move the free trial versions of the tool on any other computer. Note that this PC should not be the one from which you need to perform the actual data recovery.
  • Now install the first trial version.
  • After this, delete some files, folders, etc. using the SHIFT + Del key. This key deletes the data without moving it first to the Recycle Bin folder. You can also format a partition to perform the recovery.

Testing and Finding the Best Software to Recover the Lost Data

  • Once the deletion process is completed, launch the free trial version.
  • Browse the hard disk partition from which you have deleted the data. If you have formatted a partition, select that.
  • Start the scanning process.
  • Now, stay relaxed and do whatever you want to do because this process will take some time depending on the amount of the data to be recovered.
  • After the scanning process has been completed, you will see a list of the data recovered from the selected hard disk partition.
  • Analyze that data based on the percentage of recovery, quality, etc.
  • If you find that more than 60-70% recovery has been done and the quality is good as well, you can purchase a license key for this Data Recovery software. If the percentage of recovery is less than 60% or the quality is not good, you can uninstall this trial version and repeat the above process once again until you find the best software to recover the lost data.
  • After you have come across the best software, install its licensed version on the PC where you want to perform the recovery and run it.

Caution

Please note that in the case of severe corruption, the percentage of data recovery can be less than 60%, but in such cases, few software often provide raw recovery. You may want to go ahead with that solution as well.

Conclusion

The process demonstrated above may consume temporary time, but at the end, you will have one of the best Data Recovery software that you will feel proud to recommend to others as well. However, if you do not have time for the testing, you may straight forward want to go for a well-known solution.

Two Reliable Methods To A Secure Data Destruction

Today, the mode of work has changed from keeping information in hard from to soft form. Every kind of business needs a secure network to keep its data safe. Firms spend millions of dollars on IT services to maintain their records on hard disk. Nowadays, cloud computing is also being used for preservation of sensitive files instead of desks. But, failure to comply with the requirements of security can lead to very serious repercussions for the business. Breaches of privacy, data protection, compliance issues and additional costs occurs due to improper data destruction services.

Here comes the great importance of protected hard drive disposal services. Not all the companies opt for cloud computing, which itself is also not a highly secure facility either. Majority of the online firms utilize the common source of record keeping, ie on PCs. Keeping the online files intact is one thing, but having to get rid of the information which is no more needed is another. Therefore, companies look for hiring the services of experts in the field of data disposal services without breaks.

Following are the two reliable methods to accomplish secure data destruction:

Overwriting

One method of secure hard drive disposal includes is to overwrite all the information present on hard disk with new one. It is considered to be a very economic mode of data destruction. All you have to do is get an overwriting software that can be applied on part or entire hard drive. If you have already addressed all the regions of data storage, then you just require a single pass for successful removal of stored files. You could configure the overwriting application to select specific files, free space or partitions present in hard drive. All the remnants of data are positively deleted after overwriting in order to ensure complete security.

Be that as it may, the process of replacing information on entire disk is a lengthy process to achieve. It could also not achieve removal of files present on host-protected folders. The process could be victim to data theft during the overwriting procedure due to changes in parameters. Secure hard drive disposal can only be accomplished while it is still in writable condition and not damage in any way.

Degaussing

Unlike overwriting which is done by a software, degaussing involved the usage of a specific device known as Degausser. Hard Drive Disposal and other services strongly recommend this method of data destruction. Degaussing is actually the practice of reducing magnetic field of a hard disk. By doing so, it can eliminate all files present on storage medium like floppy disk, CD, DVD, or any other kind of hard drive. One of the major advantages of this method is that it completely removes the information making it impossible to recover data.

However, highly effective degausser devices can be very costly to purchase. They are also extremely heavy to maintain. It can also cause malfunction of nearby vulnerable instruments due to its strong electromagnetic fields. In addition to that, hard drives can get permanent damage in the process.

To sum up, secure data destruction for a large sized online company can be a very tricky task to achieve. Overwriting and Degaussing are more trustworthy means of achieving that. Although, one can also look up for some other methods as well. It depends on the nature of one`s needs and financial resources. If you have a small to mid-size firm, then you could opt for Overwriting. On the other hand, if you have gotten a large company, Degaussing would be the most suitable choice.

Data Recovery: How to Recover From a Hard Drive Failure

Context: Unfortunately, most home users, and many business users, do not back up their systems. Moreover, many small businesses have older back-up procedures that are often ineffective for recovering files. Of course, you can run down to your neighborhood electronics store and purchase a replacement drive for your computer, but what about your data on…

Context:
Unfortunately, most home users, and many business users, do not back up their systems. Moreover, many small businesses have older back-up procedures that are often ineffective for recovering files.

Of course, you can run down to your neighborhood electronics store and purchase a replacement drive for your computer, but what about your data on the failed hard drive? How important was it? Did you save it or back it up?

What to do:
If you need to recover data on the hard drive, the first thing to do is avoid trying to reboot or doing anything that involves the drive. Doing so can actually do more damage to your data.

The only irreversible data loss is caused by overwriting bits, physical damage to the drive platters or destruction of the magnetization of the platters, which seldom happens in the real world. In the majority of cases, the malfunction is caused by a damaged circuit board, failure of a mechanical component and crash of internal software system track or firmware.

In the case of actual hard drive failure, only a data recovery professional can get your data back. And the fact that you can not access your data through your operating system does not necessarily mean that your data is lost.

As a “rule of thumb,” if you hear a clicking sound from your hard drive, or if the computer's SMART function indicates an error during the boot process, something is wrong. You should immediately stop using the hard drive in order to avoid causing further damage and, potentially, rendering the information on the hard drive unrecoverable.

After receiving your failed hard drive, a data recovery specialist's first step will be to try and save an image of the damaged drive onto another drive. This image drive, not the actual damaged drive, is where the data recovery specialist will try to recover the lost data.

The next step in the imaging process is to determine if the hard-drive failure was an actual malfunction, a system corruption or a system track issue.

System corruption and system track issues are typically fixed by using a specialist's data recovery software. System corruption or system track recoveries do not require processing in a clean room environment.

Conclusion:
Unfortunately, damage to a drive's circuit board or failure of the head drives is not uncommon. In each of these failures, a data recovery specialist should work on the system only in a clean room environment. There, the specialist can replace parts such as drive electronics, internal components, read / write arms, writing / reading heads, spindle motors or spindle bearings from a donor drive in order to gain access to the data on the failed hard drive. In most cases, the data recovery specialist is able to retrieve and return the lost data.

VNA and PACS: The Answers to Effective Management of Exponentially Growing Healthcare Data

Healthcare systems are generating more patient data than ever before. With the progress of diseases, the “data footprint” of each patient increases over time, thereby increasing the overall amount of data, which the appropriate bodies (mostly health care providers) must manage. Large amounts of data are inherently difficult to manage, but an abundance of data…

Healthcare systems are generating more patient data than ever before. With the progress of diseases, the “data footprint” of each patient increases over time, thereby increasing the overall amount of data, which the appropriate bodies (mostly health care providers) must manage.
Large amounts of data are inherently difficult to manage, but an abundance of data also means that better analytical results can be derived, which is necessary to drive lower cost and better patient outcomes. Consequently, there is a huge demand for data management platforms in healthcare and allied industries for efficiently storing, retrieving, consolidating, and displaying data.

A Vendor Neutral Archive (VNA) is an integral component of modern health data management. A VNA is a storage solution software that can store images, documents, and other clinically relevant files in a standard format with a standard interface.

Data stored in a VNA can be freely accessed by other systems, regardless of those systems' manufacturers. This interoperability is a hallmark of any VNA system. The term “Neutral” in the acronym VNA has huge implications, as it makes the data stored in VNA, platform-independent. VNAs make it easier to share data across the healthcare system, facilitating communication between departments. They enable imaging clinicians to use software that integrates images with the EHR, in order to help make better-informed diagnoses.

A VNA can also help make data more secure. VNAs that use cloud-based storage can offer better recovery options than a local-only solution. Even if the local files are corrupted or destroyed, the data remains intact in a secure location through a cloud server.

Another hidden advantage of VNAs is the lowering of administrative costs. Fewer systems and fewer points of access mean less overhead for the IT department. And there is no need to migrate data when systems are updated or replaced, a procedure that can be resource-intensive. VNAs potentially offer lower storage costs, as compared to separate PACS systems, through the healthcare system as well. VNAs use information lifecycle management applications to automatically shift older data to less expensive long-term storage, keeping only the most used data on higher-cost quick-access media.

Implementing a VNA is a major shift in a healthcare system's operating procedures. This shift can disappear a multitude of opportunities to increase efficiency, streamline workflows, and lower costs.

PACS
Modern diagnostic practices generate an intense amount of pictures and pictorial data. PACS stands for Picture Archive and Communication System. The main purpose of PACS is to simplify the management of images related to patient monitoring through the treatment and recovery. Modern radiology practices involve digital imaging. Therefore, for the purpose of interoperability, a standard is required, which is identified by all the stakeholders and is accepted as a norm.

The case in point is DICOM, which stands for Digital Imaging and Communications in Medicine. PACS that adhere to DICOM standards are better suited to accommodate digital image data generated through medical devices procured from different vendors. In other words, DICOM-compliant PACS have better interoperability and a wider coverage for storing and processing different types of digital images generated through varied medical procedures.

The conventional advantages of PACS include duplication removal, quick access of patients 'images and reports, remote sharing of patient's data and reports within an organization or to other organizations, and the establishment of chronology in patients' radiology results, in order to facilitate comparison with previous studies on same or other patients.

BEST ENTERPRISE IMAGING STRATEGY: WHAT SUITS YOUR NEEDS
With a multitude of vendors offering enterprise image management systems, it becomes difficult to make the best choice. Each organization is different in terms of organization hierarchy, as well as the type of network used for communication and financial constraints. Consequently, the requirements for enterprise imaging solutions for each one of these will be different, and no one vendor alone can satisfy all of these claims.

GE Healthcare and Philips offer some of the most exciting PACS solutions. These two vendors have a unique distinction of having a global clientele and providing enterprise archive-centric strategies. An enterprise archive returns to long-term storage for managing and collecting data from multiple imaging departments.

If organization's needs are more VNA-centric, then vendors with exclusive VNA expertise should be considered. An example of a VNA-centric expert would be Agfa. Agfa provides VNA solutions at the enterprise level for handling both DICOM and non-DICOM data.

Irrespective of the size of one's facility or a number of patients one has contact with, you need to make image storage a necessity, because physicians require a seamless access to them. As a thumb rule, it is imperative to say that any large organization with dedicated departments for various diagnostic imaging (or at least a dedicated radiology department) should have a PACS system in place. If financial constraints are not in place, then a hybrid system incorporating both VNA and PACS should be used for cloud-based storage. Hybrid systems with cloud-based storage are considered to be one of the most efficient modalities in current enterprise imaging management.

Contemplating The Cloud: A Viable Solution For Everyone

What is cloud computing? Cloud computing (or cloud storage), is the process of storing data online and it is gaining in popularity for several reasons.

What is cloud computing?

Cloud computing (or cloud storage), is the process of storing data online and it is gaining in popularity for several reasons. It is a secure way to store information, data is password protected, it can be easily shared with others, it can not get lost, damaged or stolen and it takes up no physical space on your computer.

Until now, data was stored physically on disks, hard drives or flash drives. The downside to this is that it takes up space to store the info, there is always the risk of materials getting lost, damaged or stolen and if you want to share it you have to make copies and somehow safely get it to another person at a different location.

There are many benefits that cloud computing companies offer, including:

Cloud storage offers you as much or as little space as you need-and you only pay the host for what you use. This saves you money and is great for businesses that may require more space, say, at busy times of the year and less space in off-season times.

Any required maintenance is taken care of by the host, so you do not need a large IT department.

Access your files any time from any device

You may get access to documents, programs, templates and other applications provided by the host company. The main benefit of this is that you do not have to download anything on your computer … it's all on the host's site. This saves space on your PC while everything you need is just a click away.

Password-protect specific files and folders to keep them private and share them with only those you choose to.

How do I get started?

To take advantage of cloud computing, you must first decide on a host. This is the cloud computing company that will build, maintain and protect the 'cloud' where your information will be stored. Cloud computing companies offer a wide array of services and can range veryly in price. Some are free, some are as little as $ 1 a month and still others can charge over $ 50 a year. It is important to choose the host that is right for your business.

Here are the 3 most popular cloud computing companies:

Google Drive – Google's service is free for the first 15GB of space. Also, it not only stores your data, but also offers you the option to create, edit, store and share images, music, files and forms. It can be used with Google Docs-easy-to-use templates to help you create the best documents.

DropBox- They have a free and paid version. Dropbox is super secure and you can give password-protected access to specific folders to select people so they see only what they need to see and nothing else. Live chat and phone support take the guesswork out of setting up your site.

JustCloud- Offering free and paid accounts-as little as $ 3.95 a month-this company offers easy drag and drop customization, bank-grade encryption and the ability to sync multiple computers so you have 100% access to your files, all the time.

Data loss is crippling for any business, especially in the age of big data where companies rely on digital information to refine their marketing, contact prospects, and process transactions. Reducing the chances for data loss is a vital part of a data management strategy.

The first goal should be to prevent data loss from occurring in the first place. There are many reasons which could lead to data loss. A few of them are listed below:

1) Hard drive failures

2) Accidental deletions (user error)

3) Computer viruses and malware infections

4) Laptop theft

5) Power failures

6) Damage due to spilled coffee or water; Etc.

However, if a loss does occur, then there are some best practices you can implement to boost your odds of recovery.

Secondly, do not put all your storage eggs in the cloud basket. The cloud is vital for cost-effective storage, but it does have some pitfalls that should not be ignored. Many examples of data loss have occurred from an employee simply dropping their computer or hard drive, so talk to staff members about best practices. SD cards are much more fragile and should never be used as a form of longer-term storage.

Here's a look at top ways you can protect your data from loss and unauthorized access.

Back up early and often

The single most important step in protecting your data from loss is to back it up regularly. How often should you back up? That depends-how much data can you afford to lose if your system crashes completely? A week's work? A day's work? An hour's work?

You can use the backup utility built into Windows (ntbackup.exe) to perform basic backups. You can use Wizard Mode to simplify the process of creating and restoring backups or you can configure the backup settings manually and you can schedule backup jobs to be performed automatically.

There are also numerous third-party backup programs that can offer more sophisticated options. Whatever program you use, it's important to store a copy of your backup offsite in case of fire, tornado, or other natural disaster that can destroy your backup tapes or disks along with the original data.

Diversify your backups

You always want more than one backup system. The general rule is 3-2-1. You should have 3 backups of anything that's very important. They should be backed up at at least two different formats, such as in the cloud and on a hard drive. There should always be an off-site backup in the event that there is damage to your physical office.

Use file-level and share-level security

To keep others out of your data, the first step is to set permissions on the data files and folders. If you have data in network shares, you can set share permissions to control what user accounts can and can not access the files across the network. With Windows 2000 / XP, this is done by clicking the Permissions button on the Sharing tab of the file's or folder's properties sheet.

However, these share-level permissions will not apply to someone who is using the local computer on which the data is stored. If you share the computer with someone else, you'll have to use file-level permissions (also called NTFS permissions, because they're only available for files / folders stored on NTFS-formatted partitions). File-level permissions are set using the Security tab on the properties sheet and are much more granular than share-level permissions.

In both cases, you can set permissions for either user accounts or groups, and you can allow or deny various levels of access from read-only to full control.

Password-protect documents

Many productivity applications, such as Microsoft Office applications and Adobe Acrobat, will allow you to set passwords on individual documents. To open the document, you must enter the password. To password-protect a document in Microsoft Word 2003, go to Tools | Options and click the Security tab. You can require a password to open the file and / or to make changes to it. You can also set the type of encryption to be used.

Unfortunately, Microsoft's password protection is reliably easy to crack. There are programs on the market designed to recover Office passwords, such as Elcomsoft's Advanced Office Password Recovery (AOPR). This type of password protection, like a standard (non-deadbolt) lock on a door, will deter casual would-be intruders but can be fairly easily circumvented by a determined intruder with the right tools.

You can also use zipping software such as WinZip or PKZip to compress and encrypt documents.

Use EFS encryption

Windows 2000, XP Pro, and Server 2003 support the Encrypting File System (EFS). You can use this built-in certificate-based encryption method to protect individual files and folders stored on NTFS-formatted partitions. Encrypting a file or folder is as easy as selecting a check box; just click the Advanced button on the General tab of its properties sheet. Note that you can not use EFS encryption and NTFS compression at the same time.

EFS uses a combination of asymmetric and symmetric encryption, for both security and performance. To encrypt files with EFS, a user must have an EFS certificate, which can be issued by a Windows certification authority or self-signed if there is no CA on the network. EFS files can be opened by the user whose account encrypted them or by a designated recovery agent. With Windows XP / 2003, but not Windows 2000, you can also schedule other user accounts that are authorized to access your EFS-encrypted files.

Note that EFS is for protecting data on the disk. If you send an EFS file across the network and someone uses a sniffer to capture the data packets, they'll be able to read the data in the files.

Use disk encryption

There are many third-party products available that will allow you to encrypt an entire disk. Whole disk encryption locks down the entire contents of a disk drive / partition and is transparent to the user. Data is automatically encrypted when it's written to the hard disk and automatically decrypted before being loaded into memory. Some of these programs can create invisible containers inside a partition that act like a hidden disk within a disk. Other users see only the data in the “outer” disk.

Disk encryption products can be used to encrypt removable USB drives, flash drives, etc. Some allow creation of a master password along with secondary passwords with lower rights you can give to other users. Examples include PGP Whole Disk Encryption and DriveCrypt, among many others.

Make use of a public key infrastructure

A public key infrastructure (PKI) is a system for managing public / private key pairs and digital certificates. Because keys and certificates are issued by a trusted third party (a certification authority, either an internal one installed on a certificate server on your network or a public one, such as Verisign), certificate-based security is stronger.

You can protect data you want to share with someone else by encrypting it with the public key of its intended recipient, which is available to anyone. The only person who will be able to decrypt it is the holder of the private key that corresponds to that public key.

Hide data with steganography

You can use a steganography program to hide data inside other data. For example, you could hide a text message within a.JPG graphics file or an MP3 music file, or even inside another text file (although the latter is difficult because text files do not contain much redundant data that can be replaced with the hidden message). Steganography does not encrypt the message, so it's often used in conjunction with encryption software. The data is encrypted first and then hidden inside another file with the steganography software.

Some steganographic techniques require the exchange of a secret key and others use public / private key cryptography. A popular example of steganography software is StegoMagic, a freeware download that will encrypt messages and hide them in.TXT, .WAV, or.BMP files.

Protect data in transit with IP security

Your data can be captured while it's traveling over the network by a hacker with sniffer software (also called network monitoring or protocol analysis software). To protect your data when it's in transit, you can use Internet Protocol Security (IPsec) -but both the sending and receiving systems have to support it. Windows 2000 and later Microsoft operating systems have built-in support for IPsec. Applications do not have to be aware of IPsec because it operates at a lower level of the networking model. Encapsulating Security Payload (ESP) is the protocol IPsec uses to encrypt data for confidentiality. It can operate in tunnel mode, for gateway-to-gateway protection, or in transport mode, for end-to-end protection. To use IPsec in Windows, you have to create an IPsec policy and choose the authentication method and IP filters it will use. IPsec settings are configured through the properties sheet for the TCP / IP protocol, on the Options tab of Advanced TCP / IP Settings.

Secure wireless transmissions

Data that you send over a wireless network is even more subject to interference than that sent over an Ethernet network. Hackers do not need physical access to the network or its devices; anyone with a wireless-enabled portable computer and a high gain antenna can capture data and / or get into the network and access data stored there if the wireless access point is not securely secured.

You should send or store data only on wireless networks that use encryption, preferably Wi-Fi Protected Access (WPA), which is stronger than Wired Equivalent Protocol (WEP).

Use rights management to retain control

If you need to send data to others but are worried about protecting it once it leaves your own system, you can use Windows Rights Management Services (RMS) to control what the recipients are able to do with it. For instance, you can set rights so that the recipient can read the Word document you sent but can not change, copy, or save it. You can prevent recipients from forwarding e-mail messages you send them and you can even set documents or messages to expire on a certain date / time so that the recipient can no longer access them after that time.

To use RMS, you need a Windows Server 2003 server configured as an RMS server. Users need client software or an Internet Explorer add-in to access the RMS-protected documents. Users who are assigned rights also need to download a certificate from the RMS server.
