Technical Details

what runs on :16994

Intel AMT redirection carries SOL and IDER sessions so administrators can interact with a machine independently of its operating system, including during boot. The standard redirection endpoint is TCP 16994; TCP 16995 is its TLS-protected counterpart. AMT also commonly uses ports 16992 and 16993 for its management interface. Although IANA lists both TCP and UDP for this assignment, AMT redirection is normally encountered over TCP.

security overview

This is a remote-management interface that can provide console and boot-media access, so an exposed listener can be sensitive even when authentication is required. Port 16994 is not encrypted by default; keep AMT interfaces on a trusted management network, restrict access with firewall rules, and prefer the TLS endpoint on 16995 where supported. Do not expose it directly to the internet.

port: :16994
service: Intel AMT Redirection
transport: TCPUDP
encryption: cleartext
assignment: iana registered
risk: 8/10risk
category: Remote Access Network Services
usage: This port is used by Intel Active Management Technology (AMT) for out-of-band redirection, typically to provide Serial-over-LAN (SOL) or IDE redirection (IDER) through a management console. Engineers are most likely to encounter it on AMT-enabled business PCs and servers; the usual encrypted counterpart is TCP 16995.
