Discussion

Auditing and logging are key components of any security architecture. Logging the actions of specific events provides a means to investigate an attack; to recognize resource usage or capacity thresholds; or to identify an improperly configured network device. If auditing is not comprehensive, it will not be useful for intrusion monitoring, security investigations, and forensic analysis.

Check Content

Determine if the OS10 Switch generates audit log events for a locally developed list of auditable events.

Review the OS10 Switch configuration to determine if audit logging is enabled:

!
logging audit enable

For the locally developed list of audit items review the auditd rule set with the following command:

OS10# system "sudo auditctl -l"
-a never,user
-a never,task
-w /var/run/utmp -p wa -k session
-w /var/log/btmp -p wa -k session
-w /var/log/wtmp -p wa -k session
-w /usr/bin/dpkg -p x -k software_mgmt
-w /usr/bin/apt-add-repository -p x -k software_mgmt
-w /usr/bin/apt-get -p x -k software_mgmt
-w /usr/bin/aptitude -p x -k software_mgmt
OS10#

If audit logging is not enabled or auditctl does not list rules for the desired auditable events, this is a finding.

Review the OS10 Switch configuration to determine if audit logging is enabled:

!
logging audit enable

If audit logging is not enabled, this is a finding.

Fix Text

Configure the OS10 Switch to enable audit logging:

OS10(config)# logging audit enable

Configure the switch to log a locally developed list of auditable events by adding appropriate configuration for audit as shown in the example below.

From a shell as root, add desired audit rules to a file in the /etc/audit/rules.d/ directory, as in this example:

OS10# system "sudo -i"
[sudo] password for admin:
root@OS10:~# echo “-w /var/log/sudo.log -p wa -k actions" >> /etc/audit/rules.d/audit.rules
root@OS10:~#

Delete any rules from the rule sets with the obsolete action of “entry”:

root@OS10:~# sed -i '/-a entry/d' /etc/audit/rules.d/*

Reload the rules files:

root@OS10:~# augenrules --load
