Riverbed Optimization System (RiOS) must authenticate SNMP server before establishing a local, remote, and/or network connection using bidirectional authentication that is cryptographically based.

Description
Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Bidirectional authentication provides stronger safeguards to validate the identity of other devices for connections that are of greater risk. A local connection is any connection with a device communicating without the use of a network. A network connection is any connection with a device that communicates through a network (e.g., local area or wide area network, Internet). A remote connection is any connection with a device communicating through an external network (e.g., the Internet). Because of the challenges of applying this requirement on a large scale, organizations are encouraged to only apply the requirement to those limited number (and type) of devices that truly need to support this capability. For network device management, this has been determined to be network management device addresses, SNMP authentication, and NTP authentication.

Check Text ( C-63709r1_chk )
Verify that RiOS is configured to authenticate SNMP server before establishing a local, remote, and/or network connection using bidirectional authentication that is cryptographically based (SNMP portion of the requirement). Navigate to the device Management Console Navigate to Configure >> System Settings >> SNMP Basic Verify that at least one "Host" is defined under "Trap Receivers" Verify that the "Host" defined under "Trap Receivers" is set for "Version" v3 Verify that "Enable SNMP Traps" is set If no "Host" exists under "Trap Receivers or the "Host" is not "Version" v3 and/or "Enable SNMP Traps" is not set, this is a finding.
