The SLES for vRealize must shut down the information system, restart the information system, and/or notify the system administrator when anomalies in the operation of any security functions are discovered.

Description
If anomalies are not acted upon, security functions may fail to secure the system. Security function is defined as the hardware, software, and/or firmware of the information system responsible for enforcing the system security policy and supporting the isolation of code and data on which the protection is based. Security functionality includes, but is not limited to, establishing system accounts, configuring access authorizations (i.e., permissions, privileges), setting events to be audited, and setting intrusion detection parameters. Notifications provided by information systems include messages to local computer consoles, and/or hardware indications, such as lights. This capability must take into account operational requirements for availability for selecting an appropriate response. The organization may choose to shut down or restart the information system upon security function anomaly detection.

Check Text ( C-42849r662297_chk )
Check the syslog configuration file for remote syslog servers: # cat /etc/syslog-ng/syslog-ng.conf \| grep logserver If no line is returned, or the "logserver" is commented out, this is a finding.

Fix Text (F-42808r662298_fix)
Edit the syslog configuration file and add an appropriate remote syslog server: In the "/etc/syslog-ng/syslog-ng.conf" file, the remote logging entries must be uncommented and the IP address must be modified to point to the remote syslog server: # # Enable this and adopt IP to send log messages to a log server. # #destination logserver { udp("10.10.10.10" port(514)); }; #log { source(src); destination(logserver); };

Edit the syslog configuration file and add an appropriate remote syslog server:

In the "/etc/syslog-ng/syslog-ng.conf" file, the remote logging entries must be uncommented and the IP address must be modified to point to the remote syslog server:

#
# Enable this and adopt IP to send log messages to a log server.
#
#destination logserver { udp("10.10.10.10" port(514)); };
#log { source(src); destination(logserver); };
