Technical Details

what runs on :5783

IANA registers 5783 for the 3PAR Management Service with SSL. In 3PAR deployments it is associated with secure management connections to the storage array; these are typically TCP client-server sessions, with 5782 commonly used for the corresponding non-SSL service. The management protocol is vendor-specific, and the registry's UDP listing does not establish that the same management protocol is available over UDP. Exact handshake and TLS/SSL support can depend on array and client versions.

security overview

This is a storage-management interface, so an exposed listener can provide an attacker a target for probing and attempted access to sensitive array administration functions. Keep it on a restricted management network and allow only trusted management hosts; do not expose it directly to the internet. The assignment specifies SSL, but the security of the connection depends on the deployed versions and configuration.
