💼 SC-7 Boundary Protection (L)(M)(H)

• Contextual name: 💼 SC-7 Boundary Protection (L)(M)(H)
• ID: /frameworks/fedramp-high-security-controls/sc/07
• Located in: 💼 System and Communications Protection

Description

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 [Selection: Assignment: physically; logically] 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.

SC-7 Additional FedRAMP Requirements and Guidance:

(b) Guidance: SC-7 (b) should be met by subnet isolation. A subnetwork (subnet) is a physically or logically segmented section of a larger network defined at TCP/IP Layer 3, to both minimize traffic and, important for a FedRAMP Authorization, add a crucial layer of network isolation. Subnets are distinct from VLANs (Layer 2), security groups, and VPCs and are specifically required to satisfy SC-7 part b and other controls. See the [FedRAMP Subnets White Paper] (https://www.fedramp.gov/assets/resources/documents/FedRAMP_subnets_white_paper.pdf) for additional information.
