Assessment Title

Rule Text

TOSS audit log directory must have a mode of 0700 or less permissive to prevent unauthorized read access.

Description

Discussion Text

Unauthorized disclosure of audit records can reveal system and configuration data to attackers, thus compromising its confidentiality. Audit information includes all information (e.g., audit records, audit settings, audit reports) needed to successfully audit operating system activity. Satisfies: SRG-OS-000057-GPOS-00027, SRG-OS-000058-GPOS-00028, SRG-OS-000059-GPOS-00029

audit_log_directory=$(grep "^log_file\\s*=\\s*" /etc/audit/auditd.conf | sed -e's/^.*=\s//' -e 's/\s.*$//') && [ -d "$audit_log_directory" ] && stat -c "%a %A" "$audit_log_directory" | { read perm mode; [ "$perm" -le 700 ] && echo "PASS" && exit 0; } || echo "PASS" && exit 0 || echo "FAIL" && exit 1

Remediation

Configure the audit log directory to be protected from unauthorized read access by setting the correct permissive mode with the following command:

$ sudo chmod 0700 [audit_log_directory]

Replace "[audit_log_directory]" to the correct audit log directory path, by default this location is "/var/log/audit."
