# SC-10 — Network Disconnect

- **Control ID:** SC-10
- **Family:** [SC](/md/families/SC.md)
- **Baselines:** moderate, high
- **Enhancement of:** No content available.

## Description

Terminate the network connection associated with a communications session at the end of the session or after \[assignment\] of inactivity.

## Discussion

Network disconnect applies to internal and external networks. Terminating network connections associated with specific communications sessions includes de-allocating TCP/IP address or port pairs at the operating system level and de-allocating the networking assignments at the application level if multiple application sessions are using a single operating system-level network connection. Periods of inactivity may be established by organizations and include time periods by type of network access or for specific network accesses.
