Linux kernel hardening: Kernel parameters with sysctl

Linux kernel security can be increased at runtime using sysctl, allowing to mitigate potential vulnerabilities and exploits.

This article describesseveral kernel parameters that have implications in the security of the system and how to harden these parameters. Note that for certain parameters, there are tighter values. However, for the sake of the balance between security and usability, this article does not include the ‘strictest’ values for those kernel parameters.
