Here's our take.

SELinux

Nice Pick

Developers should learn and use SELinux when building or deploying applications on Linux systems that require enhanced security, such as in government, financial, or high-compliance environments

Pros

• It is particularly useful for isolating services, preventing privilege escalation attacks, and enforcing least-privilege principles in multi-user or containerized setups
• Related to: linux-security, mandatory-access-controls

Cons

• Specific tradeoffs depend on your use case

grsecurity

• Related to: linux-kernel, selinux

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use SELinux if: You want it is particularly useful for isolating services, preventing privilege escalation attacks, and enforcing least-privilege principles in multi-user or containerized setups and can live with specific tradeoffs depend on your use case.

Use grsecurity if: You prioritize g over what SELinux offers.

The Bottom Line

SELinux wins

Developers should learn and use SELinux when building or deploying applications on Linux systems that require enhanced security, such as in government, financial, or high-compliance environments
