Ways To Secure Your Cloud

Some of the most important points to be considered while deciding your approach toward you cloud security is the extent of data security needed and how mission critical the application is. You can adopt for two methods namely site-to-site VPN terminations and setting up additional security layers such as CloudSpan. With each selection you will have to deal with the pros and cons of each in terms of cost, performance, complexity, and latency overhead.

Following are some of the methods to strengthen public cloud security for your enterprise.

Selecting appropriate apps for public cloud

Generally many start-ups beginning with public cloud for their application need, which even include mission-critical applications and their data. The basic security provided by public cloud service provider (CSP) is more than enough for cases such as websites, application development, testing, online cataloguing and product documentation.

But CSP is capable of providing varied levels of security for public cloud. This should be kept in mind while evaluations CSP.

Evaluating and comparing different CSP’s, based on the ISO/IEC27000 series of standards, is important while shifting sensitive applications and data to public cloud. Another thing that can be done is extending the security policies applied for the public cloud to cover instances of the public cloud. There are some security providers who enforce the same standards of information and application on private and public instances.

Choose the right third-party auditing services

When it comes to security compliance organizations need not take CSP’s word as the last word. There is a provision of a third party auditing the actual application of security standards, the process and procedures of a CSP.

Take SAS 70 Type 2 standards for example which specify that, audits can last for minimum of six months but could last longer than that. With this kind of audits organizations can gain confidence in moving more sensitive applications and data to the cloud.

Authenticate your data and applications

For public cloud instances most of the CSPs do provide good authentication services, but there are products which can help add an additional layer of authentication. But you must pay heed to the possibility of degradation when you weigh the benefits with disadvantages. It also increases the possibility of network latency and additional points of failure.

Possibility of affecting integration due to added security

CSP’s provide robust security as a default setting. And therefore adding another measure may affect the entire application performance. Your identity and access management efforts may get complicated.  When you are working with mission-critical applications all these added layers become crucial. This will affect other business applications-end users who will not like it if the application is not available when they need it.

Put security on the forefront of your SLA

Make sure that you put public cloud security guarantees with CSPs as your SLA. Contract will lose its validity if transparent monitoring and reporting functions are not available.
