Fix Recommendation

Configure the SUSE operating system to implement ASLR by running the following commands:

> 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'

> sudo sysctl --system

Check Contents

Verify the SUSE operating system implements ASLR.

Check that the SUSE operating system implements ASLR by running 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.
