Check: GEN007020

HP-UX 11.23 STIG: GEN007020 (in version v1 r8)

Title

The Stream Control Transmission Protocol (SCTP) must be disabled unless required. (Cat II impact)

Discussion

The SCTP is an IETF-standardized transport layer protocol. This protocol is not yet widely used. Binding this protocol to the network stack increases the attack surface of the host. Unprivileged local processes may be able to cause the kernel to dynamically load a protocol handler by opening a socket using the protocol.

Check Content

Check the system for an SCTP installation: # swlist | grep -i SCTP If SCTP is installed, this is a finding.

Fix Text

Configure the system to prevent the dynamic loading of the SCTP protocol handler. Preview the removal of SCTP: # swremove -p <SCTP software product> Remove: # swremove <SCTP software product>
