Fix Recommendation

Configure SLEM 5 to implement ASLR by running the following command as an administrator:

> sudo sysctl -w kernel.randomize_va_space=2

If "2" is not the system's default value, add or update the following line in "/etc/sysctl.d/99-stig.conf":

> sudo sh -c 'echo "kernel.randomize_va_space=2" >> /etc/sysctl.d/99-stig.conf'

Reload settings from all system configuration files with the following command:

> sudo sysctl --system

Check Contents

Verify SLEM 5 implements Address space layout randomization (ASLR) with the following command:

> sudo sysctl kernel.randomize_va_space
kernel.randomize_va_space = 2

If the kernel parameter "randomize_va_space" is not equal to "2", or nothing is returned, this is a finding.
