Vulnerability discussion

Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing these events could serve as evidence of potential system compromise.

Check content

Verify auditd is configured to audit failed file access attempts. There must be both an "-F exit=-EPERM" and "-F exit=-EACCES" for each access syscall: # cat /etc/audit.rules /etc/audit/audit.rules | grep -e "-a exit,always" | grep -e "-S open" | grep -e "-F exit=-EPERM" # cat /etc/audit.rules /etc/audit/audit.rules | grep -e "-a exit,always" | grep -e "-S open" | grep -e "-F exit=-EACCES" There must be both an "-F exit=-EPERM" and "-F exit=-EACCES" for each access syscall. If not, this is a finding.

Fix text

Edit the audit.rules file and add the following line(s) to enable auditing of failed attempts to access files and programs: -a exit,always -F arch=b64 -S open -F exit=-EPERM -a exit,always -F arch=b64 -S open -F exit=-EACCES -a exit,always -F arch=b32 -S open -F exit=-EPERM -a exit,always -F arch=b32 -S open -F exit=-EACCES

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
