HP-UX 11.31 STIG: GEN003090 (in versions v1 r19 through v1 r13)

Title

Crontab files must not have extended ACLs. (Cat II impact)

Discussion

To protect the integrity of scheduled system jobs and to prevent malicious modification to these jobs, crontab files must be secured. ACLs on crontab files may provide unauthorized access to the files.

Check Content

Check the permissions of the crontab files. # ls -lL /var/spool/cron/crontabs If the permissions include a "+", the file has an extended ACL, this is a finding.

Fix Text

Remove the optional ACL from the file. # chacl -z <crontab file>
