6.2.8 Ensure no duplicate group names exist

Audit#

Run the following script and verify no results are returned: 

1
2
3
4
5
#!/bin/bash

cut -d: -f1 /etc/group | sort | uniq -d | while read -r x; do
 echo "Duplicate group name $x in /etc/group"
done

Remediation#

Based on the results of the audit script, establish unique names for the user groups. File group ownerships will automatically reflect the change as long as the groups have unique GIDs.
