Riverbed Optimization System (RiOS) must provide audit record generation capability for DoD-defined auditable events within the network device.

Description
Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the network device (e.g., process, module). Certain specific device functionalities may be audited as well. The list of audited events is the set of events for which audits are to be generated. This set of events is typically a subset of the list of all events for which the system is capable of generating audit records. DoD has defined the list of events for which the device will provide an audit record generation capability as the following: (i) Successful and unsuccessful attempts to access, modify, or delete privileges, security objects, security levels, or categories of information (e.g., classification levels); (ii) Access actions, such as successful and unsuccessful logon attempts, privileged activities or other system level access, starting and ending time for user access to the system, concurrent logons from different workstations, successful and unsuccessful accesses to objects, all program initiations, and all direct access to the information system; and (iii) All account creation, modification, disabling, and termination actions.

Details

Check Text ( C-63685r1_chk )
Verify that RiOS is configured to off-load audit records (logs) onto a different system than the system being audited. Navigate to the device Management Console Navigate to Configure >> System Settings >> Logging Verify that "Remote Log Servers" contains IP addresses for all available log servers View "Per-Process Logging" section to see if a process or severity has been configured. Note: This only affects the system log, not the user type facilities. If a filter has been added in 'Per-Process Logging" which prevents the capture of DoD-defined auditable events, this is a finding. If "Remote Log Servers" is empty and no remote log servers are configured, this is a finding.
