The Juniper EX switch must be configured to prohibit the use of cached authenticators after an organization-defined time period.

Description
Some authentication implementations can be configured to use cached authenticators. If cached authentication information is out-of-date, the validity of the authentication information may be questionable. The organization-defined time period should be established for each device depending on the nature of the device; for example, a device with just a few administrators in a facility with spotty network connectivity may merit a longer caching time period than a device with many administrators.

Check Text (C-253927r961521_chk)

Review the network device configuration to determine if the network device or its associated authentication server prohibits the use of cached authenticators after an organization-defined time period. Verify idle-timeouts, SSH keepalive messages, and SSH rekey are configured to meet the requirements of the target network. [edit system] login { idle-timeout 10; } system { services { ssh { protocol-version v2; client-alive-count-max (0..255); client-alive-interval (0..65535 seconds); rekey { data-limit (51200..4294967295 bytes); time-limit (1..1440 minutes); } } } } For externally authenticated accounts, verify the external authentication server enforces appropriate authenticator timeouts. If cached authenticators are used after an organization-defined time period, this is a finding.
