SC-07(05) [M] Deny by Default — Allow by Exception
Control
Deny network communications traffic by default and allow network communications traffic by exception [Selection(one-or-more): at managed interfaces; for {{ insert: param, sc-07.05_odp.02 }} ].
Discussion
Denying by default and allowing by exception applies to inbound and outbound network communications traffic. A deny-all, permit-by-exception network communications traffic policy ensures that only those system connections that are essential and approved are allowed. Deny by default, allow by exception also applies to a system that is connected to an external system.
Assessment Objective
- network communications traffic is denied by default [Selection(one-or-more): at managed interfaces; for {{ insert: param, sc-07.05_odp.02 }} ];
- network communications traffic is allowed by exception [Selection(one-or-more): at managed interfaces; for {{ insert: param, sc-07.05_odp.02 }} ].
