Technical Details

what runs on :160

SGMP trap messages are normally sent as UDP datagrams from an agent to a management station; the IANA assignment lists both TCP and UDP for this service. Traps are unsolicited event notifications rather than request/response polling, and SGMP traffic is unencrypted. SGMP is associated with port 153, while the later SNMP protocol commonly uses ports 161 for queries and 162 for traps.

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

security overview

SGMP provides no modern confidentiality or integrity protection, so exposed traffic can reveal device and network state and may be spoofed or modified. Because the protocol is obsolete and rarely deployed, port 160 should normally be blocked from the public Internet and restricted to trusted management networks.
