Review the network topology diagram.

If there is a connection between the classified network and the unclassified network for the purpose of tunneling classified traffic across a non-DISN or OCONUS DISN unclassified IP network, verify there is approval by the DSAWG.

If there is no document stating DSAWG approval, this is a finding.
