Port 5674HyperSCSI

HyperSCSI is a niche SCSI-over-Ethernet storage protocol; port 5674 is rarely encountered and should be confined to trusted storage networks.

Technical Details

what runs on :5674

HyperSCSI carries SCSI storage commands and data over Ethernet for access to remote storage. IANA assigns port 5674 for both TCP and UDP, but publicly available descriptions of HyperSCSI emphasize Ethernet storage transport and do not establish a widely deployed TCP/UDP handshake, framing, or default implementation. Do not infer a specific wire protocol or identify a service from the port alone; this is not a typical web or general-purpose application listener.

Security Information

risk score

2/ 10safe

routine exposure. this port is rarely the way in on its own — keep it patched and logged and move on.

network services averages 2.6 across 1,657 ports — this one sits 0.6 below.

reachable over

tcp · udp

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

security overview

A reachable storage endpoint could expose data or permit damaging operations on attached storage, so it should not be exposed to the public internet. Restrict it to a trusted storage network and known peers. Do not assume traffic is encrypted or that a particular implementation provides strong authentication.

Record

encryption: cleartext
assignment: iana registered
risk: 2/10safe
category: Network Services System
usage: HyperSCSI is a specialized storage networking protocol for carrying SCSI operations to remote storage. A listener on TCP or UDP port 5674 would be a HyperSCSI-capable storage endpoint; it is not a commonly observed internet service. The assignment was made to the Data Storage Institute.
