1. A system, comprising:
a first data storage device comprising:
a non-volatile storage medium configured to store host data;
a processor;
a memory;
a host interface configured to connect to a host system via a storage interface bus for receiving storage commands from the host system through first physical channels and transport protocols of the storage interface bus;
a peer interface configured for peer communication with a plurality of peer data storage devices, wherein the peer interface is further configured to connect to a control bus that is physically distinct from the storage interface bus and uses second physical channels and transport protocols that are different than the first physical channels and transport protocols for peer communication;
a vulnerability manager configured to determine a security issue for the first data storage device; and
a peer messaging service configured to send, through the peer interface and responsive to determining the security issue, a threat notification to at least one peer data storage device of the plurality of peer data storage devices.
