SC-07(05) 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

  1. network communications traffic is denied by default [Selection(one-or-more): at managed interfaces; for {{ insert: param, sc-07.05_odp.02 }} ];
  2. network communications traffic is allowed by exception [Selection(one-or-more): at managed interfaces; for {{ insert: param, sc-07.05_odp.02 }} ].

Assessment Method

Examine

System and communications protection policy procedures addressing boundary protection system design documentation system configuration settings and associated documentation system audit records system security plan other relevant documents or records

Interview

System/network administrators organizational personnel with information security responsibilities system developer organizational personnel with boundary protection responsibilities
