Technical Details

what runs on :2269

MIKEY, specified in RFC 3830, exchanges keying material and security parameters for multimedia sessions. It supports pre-shared-key, public-key, and Diffie–Hellman exchange modes, with authenticated and optionally encrypted payloads; the resulting keys are typically used by SRTP rather than by MIKEY itself. The registered service uses both TCP and UDP port 2269, but MIKEY can also be encapsulated in application signaling such as SIP/SDP.

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

MIKEY exposure can permit probing, denial-of-service attempts, and attacks against weak authentication or key-management configurations. It should normally be restricted to trusted signaling peers; the security of the exchange depends on the selected MIKEY mode, credential protection, and the surrounding VoIP system. MIKEY traffic is not necessarily wholly encrypted by default, even when it transports protected keying material.

Record

iana registry entry

port: :2269
service: Multimedia Internet KEYing (MIKEY)
transport: TCPUDP
encryption: cleartext
assignment: iana registered
risk: 2/10safe
category: Security Voice and Chat
usage: MIKEY is a key-management protocol used with real-time voice and multimedia protocols, especially SRTP-based VoIP and conferencing. It may use TCP or UDP port 2269, although deployments commonly carry MIKEY messages within SIP/SDP signaling instead of exposing this port directly.
