Encryption of Data in the Cloud

Many organisations are nowadays looking on how to take advantage of cloud computing, but security of their data remains a serious concern. However, there are several mechanisms which can help you in encrypting your data in cloud and ensure there is effective data protection.

As organisations grow in size, they experience security challenges which they lack knowledge and experience to handle. Although most IT experts conclude that encryption of cloud data is the key to security, the approach can be daunting, and especially for small to mid-sized businesses. The process of managing encryption keys in a cloud environment is not easy. The encryption key should be kept separate from the encrypted data, and this is a challenge, especially in a cloud environment with an asymmetrical growth.

Encryption keys should be stored in a separate storage block or server. To stay protected against disasters, the encryption keys should be backed up in offline storage. The backup needs to be audited on a regularly basis, probably each month to ensure that it is free from corruption. Although some of the keys will expire automatically, others need to be refreshed, thus, calling for the need for a refresh schedule. For improved security, the key themselves should be encrypted, while the master and recovery keys should be given a multi-factor authentication.

It is good for any organisation to let a third party manage the encryption keys rather than the IT department of the organisation. If you encrypt the data before uploading it to your cloud storage provider, and then it happens that the same data is needed on a remote or mobile device having no decryption keys, the downloaded data will be useless. In case the company is in need of sharing the data with their business partner, and they don’t need the partner to access the decryption keys directly, this will become complex.

The following are some of the criteria which can be used for encrypting data in the cloud:

Exercise discretion

You have to determine the percentage of your organisation data which is considered as being sensitive. You will find that majority of your organisation data does not need to be encrypted. With a ubiquitous encryption, the functionality of the application can be interrupted, most probably the search and report functionality, and these are very important in the today’s cloud model. A discretionary approach to encryption should ensure that the sensitive data has been secured without interference with the advantages associated with emerging technologies.

Adherence to security policy of the corporate
The security policy for your organisation can help you determine the sensitive information in the environment and then make use of the strategy to create a strategy for the encryption strategy. Both the internal and external regulations in relation to the business have to be considered.

Automation-ready encryption
Once you have agreed on what needs to be encrypted, an action should be taken. Security technologies should be leveraged for identification of sensitive information in the corporate, and the encryption should be used as a remediation tool for risky situations. Once this process has been automated, inappropriate exposure of data will have been mitigated in a content-aware manner.

Consider the human element
Any data security mechanisms must consider the needs of the end users. If the security program of the corporate interferes with the normal workflow of the users, they will have to seek for alternatives to bypass the corporate network entirely.

Cloud providers and their potential SaaS partners should be asked about the protocol they use when transmitting their data. The SSL (Secure Socket Layer) protocol is now not the best since the discovery of a man-in-the-middle attack discovered in 2014. This can only be solved by implementation of TLS rather than the SSL, but the problem comes in that systems running older operating systems such as Windows XP are not able to implement the TLS. This has made some businesses to continue using SSL despite the risk it poses of exposing confidential data. The main solution to this problem is disabling the SSL completely, either on the server or client side, but this will make it inaccessible by systems which rely only on SSL.

DLP (Data Loss Prevention) in the Cloud

Most organizations have moved their sensitive data to the cloud, but they lack policy controls for the cloud data. Research has shown that 21% of the documents uploaded to the cloud have sensitive data such as protected health information (PHI), personally identifiable information (PII), intellectual property or payment card data and this creates concerns in terms of cloud compliance. In the year 2014, breaches in cloud data rose.
Most organizations have made an investment in tools for data loss prevention so as to protect loss or theft of their on-promise information and adhere to data compliance laws. The problem is that most of these tools have been made to protect data contained in emails and file servers, meaning that they address issues to do with mobile security and cloud governance since the data will always be passed to unsanctioned cloud services which are regularly accessed by unsecured devices. It has been found each average organizations will upload 3.1GB of data each day, and it is expected that 1/3 of organization data will be in the cloud by 2016. You have to recognize that migration of unprotected data to the cloud is risky, thus, there is a need for any organization to extend data prevention policies to take care of the data in the cloud to protect against being exposed.
Whenever you are addressing DLP, consider the following requirements:
1. Know the activity-level usage in your apps, and then use DLP to identify the activities dealing with sensitive data, anomalies and non-compliant behavior.
2. The cloud DLP software to be used should know the context which surrounds all the activity whenever you are dealing with sensitive data.
3. Restrictions and controls should be formulated in the organization to ensure that sensitive data is used safely.
4. Cloud activities should be tracked at app, user and activity level for compliance and auditing purposes.
5. Sensitive content which is residing in the cloud or moving to the cloud apps has been encrypted.

 

A number of tools for preventing data loss in the cloud have been developed. With NetScope Active Cloud, sensitive data for an organization can be protected from breaches and leaks. The tool provides advanced mechanisms for data loss prevention such as custom regular expressions, over 3000 data identifiers, support for over 500 file types, double-byte characters for international support, proximity analysis, exact match and fingerprinting. Once the tool detects some sensitive data, it use context for narrowing the content down, increasing the accuracy of detection and in reducing false positives.
Skyhigh is another DLP tool, and it extends the ability of an organization to protect against loss of data to the data stored in the cloud. With Skyhigh, DLP policies are enforced in a real-time manner, and we are provided with the capability to carry out an on-demand scan for the data which has been stored in the cloud so as to know whether we have some data outside the cloud policy. When configuring the DLP policies, you can choose a number of policy actions such as quarantine, alert, tombstone, or maybe choose to block the sensitive data from being uploaded to the cloud service. With Skyhigh, you are free to leverage the policies which you have created in other DLP solutions such as the EMC, Symantec, Websense and Intel McAfee using a closed loop remediation.
Symantec is also another tool which provides mechanism for data loss prevention in the cloud. It has partnered with Box, which is an online tool for file sharing and this improves the functionality of the tool. The tool is also expected to extend the data loss prevention of sensitive data which has been stored on mobile devices.

Cloud computing security: things you must know

One of the best game-changing revolutions of this particular era is Cloud Computing. The shift far from original on-premises applications and also data storage is undoubtedly well underway, with customers, small and middle sized companies, and big businesses putting data and applications into the cloud. The current issue is will it be secure to do this? Cloud Computing protection is undoubtedly the greatest concern amongst all those who are thinking about the technology. And when you are an IT manager, then it is great to be paranoid. Massive Losses from attack and cyber crime can be tremendous, and also the 2008 CSI Computer Security and Crime Survey demonstrate a standard average yearly damage of just below $300,000.

It might appear like the leap of trust to place your precious applications and data in the cloud, and even to believe in Cloud Computing security and safety to a 3rd party. However, belief is not a part of the situation, and neither ought it to be. Each and every business requirements to realize that its applications and data are safe and secure and the issue of the cloud computing protection should be tackled. The cloud comes with several security benefits.

Based on NIST, this particular cloud computing security benefits consist of:

-Moving public data to an external cloud decreases the publicity of delicate inner data
-Cloud homogeneity tends to make security testing/auditing easier
-Clouds allow automatic security management
-Disaster/Redundancy Recovery

All factors are effectively used. Cloud companies normally have a tendency to consist of rigorous cloud computing security as a part of their particular company models, frequently a lot more than an individual user might perform. To that end, it is not only an issue of the cloud computing companies implementing greater security measure, but the thing is, instead, that they deploy the safety precautions which individual companies ought to, however frequently do not.

The majority of application providers enforce a few standard of security for their applications, even though whenever cloud application providers apply their amazing strategies to Cloud Computing protection. Issues happen across international privacy laws and regulations, exposure of data to international choices, stovepipe solutions to authentication and role- dependent accessibility, and even leaks in the multi-tenant architectures.

Exceptional physical security from the Cloud Computing companies:
Deficiency of physical security is the trigger of a huge quantity of damage, and also insider attacks are the reason for the remarkably big percentage of damage. Even though the specter of the black hats cracking into your network from an underdeveloped country is certainly much real, it’s not uncommon that, the “black hat” is, in fact, a dependable employee. It is the person from accounting department with whom you have lunch. It is the woman who else gives you coffee early in the morning and remembers that you prefer two sugars. It is the latest college grad with a lot possible, who else does this type of great work on that final report.

Outstanding security from the cloud:
Apart from physical security measure, technical security is of the highest value. Hosting your individual applications and servers needs additional steps. A bigger business may need to employ dedicated IT employees for protection exclusively. Cloud computing, on the Furthermore, forms cloud computing protection straight into the cloud platform. While the business nevertheless should maintain private security in any situation, the provider makes sure that the data and applications are secure from attack. You no need to be worried about your data protection if you have cloud-based technology. Your data and applications will be risk-free.

Different Solutions to Data Protection

Data protection reliability and solutions are top points for any company with vision crucial digital information. Security and safety for digital resources include numerous components working in agreement, such as disaster recovery, accessibility protection from attack devastating damage, and also archival services. Quite simply, reliable data should be safe from both illegal accessibility or even vandalism and also the damage of physical devices, plus it is easily accessible to fulfill company requirements.

Data protection solutions can be found in numerous levels and will be offering company continuity and even data management effectiveness. IP or Intellectual property, protection is a supporting aim to make sure the company continuity.

At Application Level:

Security and safety can happen at the program or application level. This particular level relates to all those security solutions that are invoked in the interface among applications. Like an application may safeguard data without having an encrypted password; the security support provides this data. Whenever the information is used by receiving an application, an additional element of the particular service can quickly authenticate the user, permitting security protocols to occur in the code of an application.

Some other good examples of data protection solutions present in the application level are privacy services and data integrity solutions. Data could be encrypted by a program after that it is just decrypted whenever entered once again by that application to determine privacy parameters. Transmitted data could be examined by a receiving application for changes to the content to make sure the data integrity.

The IT Level and the Middleware:

Data protection solutions in this particular level might appear like ERP (enterprise resource planning) programs which might work as an umbrella across the organizational systems. This particular umbrella offers a constant security definition for every element, even though you may not this is a useful resource for significantly various department functions, for example, customer relationship versus accounting management or even distribution. Data access processes might almost all happen below this unique umbrella without having an activity of data outdoors of the limitations of the business network and even IT infrastructure.

Within Data Itself:

One potential upcoming way of data protection solutions concentrates on the incorporation of the security features in data files themselves. Security and authorization systems could be packed with a data file, including a level of security that might stay even though a file was jeopardized. Like several PDF files consist of an internal password and encryption challenges which safeguard its content, despite the fact that the file by itself will be or else available with a secure PDF reader.

Attempts for Your Data Protection:

Data protection solutions could be concentrated on more IP protection. Getting entry to mission crucial data is a primary element of company continuity. For that reason disaster recovery is an essential portion of data dependability.

Data that is available on an individual physical device or even in several media that are situated in the similar building operates the threat of enormous damage can be it from vandalism, fire or even natural disaster.

Remote solutions could be reached via safe internet connections, and they are an ideal supplement to dependability issues. Like a prolonged power outage or even equipment failure may make the data on the server useless for the time. Getting a backup that could be accessible to any laptop with an internet connection which returns data to the users’ hands rapidly and more efficiently.

As the data protection solutions carry on to develop together with IT technology, companies may much better depend on the dependability and protection of very sensitive data and even intellectual property. There are numerous solutions to data protection that can make you safe regarding your data and company privacy.
