Discussion

Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been left unattended. In addition, quickly terminating an idle session will also free up resources committed by the managed network element. Terminating network connections associated with communications sessions includes, for example, de-allocatingdeallocating associated TCP/IP address/port pairs at the operating system level, or de-allocatingdeallocating networking assignments at the application level if multiple application sessions are using a single, operating system-level network connection. This does not mean that the device terminates all sessions or network access; it only ends the inactive session and releases the resources associated with that session. Upon the termination of a session, the Ivanti ICS inherently ends the inactive session and releases the resources associated with that session.

Discussion

This configuration protects the confidentiality of Web UI sessionsessions and guards against DoS attacks. If JITC (DODIN APL) Mode is enabled, then the following protections are enforced: - Log support for detection and prevention of SMURF/SYN Flood/SSL Replay Attack. - Disable ICMPv6 echo response for multicast echo request. - Disable ICMPv6 destination unreachable response. - Password Strengthening. - Notification for unsuccessful admin login attempts. - Re-authenticationReauthentication of admin users. - Notification on admin status change. - Disable Roaming Sessions. - Disable Split Tunneling. - IP Lockout restrictions. - Disable Allowing Saving Login Information. - Disable Persistent Sessions. - Remove Browser Session Cookie. - Enable Server Certificate Trust Enforcement. When JITC and FIPS mode isare enabled, itthis enables DoS attacks such as flooding and replay attack audit logs inherently. JITC and FIPS mode are required for ICS use in DOD. When the NDcPP option is enabled, only NDcPP allowedapproved crypto algorithms are allowed.
