A BISSaN Hardened Linux Operating System image provides a security focused environment ideal for running web applications, databases and application servers and helps in mitigating common threats such as insufficient authorization, network & program attack threats.

The Operating System is thoroughly scanned, vetting each and every base component within every release leveraging a pool of industry certified security auditing tools. The Operating System is initially stripped from all the unnecessary insecure packages, settings and permissions. The base system is then further tuned, patched and hardened applying security recommendations from leading security industry organizations, standards and governing bodies such as the ISO, SOC and NIST to adhere and meet security regulations and compliance. This ensures you have a secure environment to run your application and hit the ground running upscaling your security posture and audit compliance within your organisation.

Stack Tuning: Once the Operating System has been secured it is then tuned to optimise the networking stack with thoroughly tested and benchmarked parameters ensuring the web application, database or application server can run to its most efficient capability with the required memory, process and networking stack throughput.

Included within the Image:

• Virus Scanner - ability to be executed on an adhoc basis or regular cadence to ensure files and packages are vetted appropriately and eliminate threats
• Shell Command Logger - Logs each and every users shell command executions to “/var/log/secure” for auditing and traceability purposes. Providing the ability to perform forensics and detail investigations in determining the user and the commands executed.
