716
Summary
- // if you see it open
- RFC 5191 describes message integrity and authentication when a PANA security association is available and recommends rate limiting incoming client initiation messages to mitigate denial-of-service risk.
About port 716/udp.
IANA registers UDP port 716 as pana for “PANA Messages” and cites RFC 5191. RFC 5191 defines PANA as a UDP-based transport for EAP between a client and an access network’s authenticator, supporting network access authentication. The registration identifies the protocol associated with the port; it does not show that a particular host runs PANA or establish whether the service should be reachable from the public internet.
PANA messages support authentication and authorization exchanges, session management, and optional liveness checks. RFC 5191 describes message authentication and integrity protection when a PANA security association is available, and recommends rate limiting incoming client initiation messages to improve resilience against denial-of-service attacks. These protocol properties do not establish how a specific deployment is configured or secured.
The supplied evidence does not establish deployment patterns, traffic prevalence, malware associations, or the intended audience for a listener on this port. Treat an observed UDP/716 endpoint as requiring protocol-level identification and deployment context; the port assignment alone cannot support an exposure recommendation.
