So, even if the end application is made very secure, it might be possible that the underlying infrastructure components have vulnerabilities, allowing attackers to compromise the system. This is where security hardening comes into picture.
In order to secure the complete application ecosystem, which includes the underlying infrastructure, it is essential to perform secure configuration reviews for all the participating components and harden the security accordingly. A simple way to achieve this could be going through configuration files for each component and then configuring items...
