The second step is to monitor your systems audit trails, logs, and performance on a regular basis After all, if you do not monitor your system regularly how the world would you know if an intruder is trying to steal your information.

Physical Security – when it comes to physical security, there is a little more to it than what meets the eye. One thing to keep in mind while you are securing the physical security is the fact that limiting access to trained and authorized personnel is extremely important. Besides that fact, physical security also prevents unauthorized users from making changes to the BIOS system, accessing the system by booting from an alternate source, and of course prevents them from altering the boot device.

Monitoring Your System – monitoring your system is extremely important because if you have all the data in the world, it will do you NO good unless you access it. While monitoring the system log, do not forget to check the integrity of the log files, the log data that has been collected, and review any security events that have been logged in the system.

Scanning the Oracle Linux Environment and Management Tools – running your system management tools daily will aid in your systems performance as well as help troubleshoot if any problems arise. On top of running your systems management tools, you also need to constantly check the integrity of your software and system. Running these two tools will help you find out whether your system has been compromised.

Security Software and Updates – it takes some work as you can see to create an Oracle Linux environment.

This step may not seem very important; the truth of the matter is that it is extremely important. It prevents your software from becoming outdated hence possibly allowing intruders to gain access to your system.

Review – the fifth and final phase of creating a secure Oracle Linux environment is to review all of your policies and procedures on a regular basis After all, this will prevent you from forgetting a step or missing an important update.
