Tips To Improve Your Data Center Security
A data center can be the nerve center of any organization which relies on computer systems for its day to day operations. Considering that the number of hackers out to steal corporate data from your servers is increasing by the day, proper data center security becomes one of the utmost concerns of data center administrators. If you think that it is time to improve your data center security, and it most certainly is, here are certain tips which should assist.
The very first thing that you must do is to separate the network administration related traffic from other, regular traffic of the network. The best way to do this is to eliminate of minimize the administrative traffic flowing to production servers. You should deploy proper event logging infrastructure and make sure that all the servers are configured not to accepts any administrative commands unless it comes from a regular network.
The next thing that you must do is to isolate and compartmentalize all the major business applications in such a manner that they become independent networks. In this way if one of the networks becomes exposed to any threat, it would not take down the entire data center with itself. The simplest example is defense against the distributed denial of services attacks. In case one of the networks of data center becomes exposed to such an attack, it would not take down , entire data center with itself.
The third step is to deploy an application level security system This comes in picture when your data center is also hosting to application servers. The process here is rather simple. You have to make sure that every application that runs on the application server runs in a sand boxed environment and is unable to bring any system wide changes. This would ensure that if a single application becomes a threat, it would not take the application server with it self. In order to achieve more protection at server level, you can also follow the policy of clean up. If it ain't required, it should not stay on the server. Eliminate all the unwanted applications and disable all the services which you do not want. The best approach is to use server solutions custom built to suite given requirements. The next thing which you can do is to enable logging to maximum possible event. This should be done on a complete data center level. The process is to make sure that any and everything that takes place on the servers is logged, all application activities, network activities etc, everything must be properly logged. The best approach to data center security is to use data center security policy template that has been framed in accordance with NIST data center security guidelines.
