Check: GEN000000-LNX00500

VMware ESX 3 Server: GEN000000-LNX00500 (in version v1 r2)

The /etc/sysctl.conf file must be group-owned by root. (Cat II impact)

The sysctl.conf file specifies the values for kernel parameters to be set on boot. These settings can affect the system's security.

Check /etc/sysctl.conf group ownership: # ls -lL /etc/sysctl.conf If /etc/sysctl.conf is not group-owned by root, this is a finding.

Use the chgrp command to change the group owner of /etc/sysctl.conf to root: # chgrp root /etc/sysctl.conf
