digital certificate

Contains identification data (see distinguished name) and the public key portion of a public/private key pair,

and a signature that is generated by a certificate authority. The signature ensures the integrity of the data in

the certificate (only the certificate authority can create valid certificates).

Disconnect-Ack

NAS response packet to a Disconnect-Request, indicating that the session was disconnected.

Disconnect-Nak

NAS response packet to a Disconnect-Request, indicating that the session could not be disconnected.

Disconnect-Request

RADIUS packet type sent to a NAS requesting that a user or session be disconnected.

dissolvable agent

Functionality within W-ClearPass OnGuard that performs device fingerprinting, posture assessments, and

health checks. Performs a one-time check at login to ensure policy compliance. Dissolvable agents cannot per-

form remediation; devices not meeting compliance can be redirected to a captive portal for manual remedi-

ation. Dissolvable agents are browser-based and are not installed on the endpoint. They are temporary: when

the browser page used during authentication is closed, the dissolvable agent is removed, leaving no trace.

The Web-based dissolvable agent is ideal for personal, non IT-issued devices that connect via a captive portal

and do not allow agents to be permanently installed. See also persistent agent, native agent, and OnGuard.

organization, organizational unit, and the “common name”, which is the primary name used to identify the cer-

tificate.
