RHEL-10-200644 - RHEL 10 must authenticate the remote logging server for off-loading audit logs via "rsyslog".
Information
Information stored in one location is vulnerable to accidental or incidental deletion or alteration.Off-loading is a common process in information systems with limited audit storage capacity.
RHEL 10 installation media provides "rsyslogd", 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" (a secure communications library implementing the Secure Sockets Layer (SSL), Transport Layer Security (TLS), and Datagram TLS (DTLS) protocols) creates a method to securely encrypt and off-load auditing.
The "rsyslog" supported authentication modes include:
- anon - Anonymous authentication.
- x509/fingerprint - Certificate fingerprint authentication.
- x509/certvalid - Certificate validation only.
- x509/name - Certificate validation and subject name authentication.
Satisfies: SRG-OS-000342-GPOS-00133, SRG-OS-000479-GPOS-00224
NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
Solution
Configure RHEL 10 to authenticate the remote logging server for off-loading audit logs by setting the following options in "/etc/rsyslog.d/99-forwarding.conf":streamdriver.authmode="x509/name"
Specify the logserver to prevent man-in-the-middle attacks in the following format:
streamdriver.permittedpeer="rsyslog.server.example.com"
