OL 8 must encrypt the transfer of audit records offloaded onto a different system or media from the system being audited.
An XCCDF Rule
Description
<VulnDiscussion>Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Offloading is a common process in information systems with limited audit storage capacity. OL 8 installation media provides "rsyslogd". This is a system utility providing support for message logging. Support for both internet and UNIX domain sockets enables this utility to support both local and remote logging. Coupling this utility with "gnutls" (which is a secure communications library implementing the SSL, TLS, and DTLS protocols) provides a method to securely encrypt and offload auditing.
