Discussion

The "sysctl" configuration file specifies values for kernel parameters to be set on boot. Incorrect or malicious configuration of these parameters can have a negative effect on system security.

Check Content

At the command line, run the following command:

# find /etc/sysctl.conf /etc/sysctl.d/* -xdev -type f -a '(' -perm -002 -o -not -user root -o -not -group root ')' -exec ls -ld {} \;

If any files are returned, this is a finding.

Fix Text

At the command line, run the following commands for each returned file:

# chmod 600 <file>
# chown root:root <file>
