Ensuring the system authenticates endpoint devices
Rule Title: RiOS must authenticate network management endpoint devices before establishing a local, remote, and/or network connection using bidirectional authentication that is cryptographically based.
STIG ID: RICX-DM-000109
Rule ID: SV-77445r1_rule Severity: CAT II
Vuln ID: V-62955 Class: Unclass
Without authenticating devices, unidentified or unknown devices might 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 (for example, local area or wide area network, Internet). A remote connection is any connection with a device communicating through an external network (for example, 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.
Verifying the system authenticates endpoint devices
Verify that RiOS is configured to authenticate network management endpoint devices before establishing a local, remote, and/or network connection using bidirectional authentication that is cryptographically based (network management portion of the requirement).
1. Connect to the CLI and enter these commands:
enable
show configuration full
2. Press the space bar to scroll through the configuration and verify that these commands are contained in the configuration:
no telnet-server enable
ssh server enable
web enable
no web http enable
web https enable
If any one of the above settings is missing from the configuration, this is a security vulnerability finding.
Configuring the system authenticates endpoint devices
