Technical Details

what runs on :7017

RFC 8990 defines GRASP on TCP and UDP port 7017. It exchanges CBOR-encoded messages: UDP supports discovery and related signaling, while TCP provides reliable peer-to-peer exchanges for negotiation; TCP messages are length-delimited. GRASP is commonly carried within the ACP, which provides the protected control-plane connectivity between autonomic nodes. It is a specialized network-control protocol, not a general-purpose application service.

security overview

In its normal ANIMA deployment, GRASP traffic is carried inside the ACP, whose secure channels protect control-plane traffic. GRASP itself should not be treated as an internet-facing security boundary: exposing an implementation outside that protected environment can allow reachable peers to inject signaling or consume protocol resources. Restrict it to trusted autonomic-network links and ACP interfaces; it is rarely encountered open in internet scans.

Record

iana registry entry

port: :7017
service: GRASP (Generic Autonomic Signaling Protocol)
transport: TCPUDP
encryption: tls / encrypted
assignment: iana registered
risk: 1/10safe
category: Network Services
usage: This is the IETF GRASP protocol, used by autonomic-network nodes to discover peers and coordinate or negotiate network objectives. Engineers are most likely to encounter it in networks implementing the ANIMA architecture, typically over the Autonomic Control Plane (ACP), rather than on ordinary Internet-facing hosts.
