Fix Recommendation

Configure the SUSE operating system file integrity tool to protect the integrity of the audit tools.

Add or update the following lines to "/etc/aide.conf" to protect the integrity of the audit tools:

# audit tools
/usr/sbin/auditctl p+i+n+u+g+s+b+acl+selinux+xattrs+sha512
/usr/sbin/auditd p+i+n+u+g+s+b+acl+selinux+xattrs+sha512
/usr/sbin/ausearch p+i+n+u+g+s+b+acl+selinux+xattrs+sha512
/usr/sbin/aureport p+i+n+u+g+s+b+acl+selinux+xattrs+sha512
/usr/sbin/autrace p+i+n+u+g+s+b+acl+selinux+xattrs+sha512
/usr/sbin/audispd p+i+n+u+g+s+b+acl+selinux+xattrs+sha512
/usr/sbin/augenrules p+i+n+u+g+s+b+acl+selinux+xattrs+sha512

Check Contents

Verify that the SUSE operating system file integrity tool is configured to protect the integrity of the audit tools.

Check that AIDE is properly configured to protect the integrity of the audit tools by running the following command:

# sudo cat /etc/aide.conf | grep /usr/sbin/au

/usr/sbin/auditctl p+i+n+u+g+s+b+acl+selinux+xattrs+sha512
/usr/sbin/auditd p+i+n+u+g+s+b+acl+selinux+xattrs+sha512
/usr/sbin/ausearch p+i+n+u+g+s+b+acl+selinux+xattrs+sha512
/usr/sbin/aureport p+i+n+u+g+s+b+acl+selinux+xattrs+sha512
/usr/sbin/autrace p+i+n+u+g+s+b+acl+selinux+xattrs+sha512
/usr/sbin/audispd p+i+n+u+g+s+b+acl+selinux+xattrs+sha512
/usr/sbin/augenrules p+i+n+u+g+s+b+acl+selinux+xattrs+sha512

If AIDE is configured properly to protect the integrity of the audit tools, all lines listed above will be returned from the command.

If one or more lines are missing, this is a finding.
