> Canonical page: /control/sc-7

Canonical id: `sc-7` · family `SC`

> a. Monitor and control communications at the external managed interfaces to the system and at key internal managed interfaces within the system; b. Implement subnetworks for publicly accessible system components that are [assignment] separated from internal organizational networks; and c. Connect to external networks or systems only through managed interfaces consisting of boundary protection devices arranged in accordance with an organizational security and privacy architecture.

_Control title and statement: NIST SP 800-53 Rev5 catalog (the pinned commit is in `/api` under `control_text`). The FedRAMP rules reference these controls by id only; everything below is what FedRAMP says about this id._

## Rev5 baseline membership

- certification class B (in the annual independent assessment)
- certification class C (in the annual independent assessment)
- certification class D (in the annual independent assessment)

## Key Security Indicators that reach it

- `KSI-CNA-ULN` — Using Logical Networking (Cloud Native Architecture)
  Logical networking and related capabilities are used and persistently reviewed to enforce traffic flow controls.
- `KSI-SVC-EIS` — Evaluating and Improving Security (Service Configuration)
  Information resources are persistently evaluated for opportunities to improve security and those improvements are persistently made.

## FedRAMP guidance

{
  "guidance": [
    "SC-7 (b) may be met by using any technical capability or complement of capabilities that ensures logical separation between publicly accessible components and internal networks by preventing traversal without inspection and authorization; traffic may not flow unrestricted from publicly accessible components to internal networks."
  ]
}

## Annual independent assessment

In the annual assessment subset for class B, C, D.
