Peer Storage Device Messaging for Vulnerability Management

Systems and methods for peer data storage device messaging over a peer channel, such as a control bus, for vulnerability management are disclosed. Storage devices may include a host interface configured to connect to a host system and a peer interface to establish peer communication independent of host availability. The storage devices may determine security issues (for themselves or for peer storage devices) and send a threat notification through the peer interface, enabling peer storage devices to respond to peer security threats without relying on their host connections.
