SC-10 - Network Disconnect
Control requirements
SC-10 - 0
Terminate the network connection associated with a communications session at the end of the session or after [IBM Assignment: no longer than 30 minutes for RAS-based sessions or no longer than 60 minutes for non-interactive user sessions] of inactivity.
Implementation guidance
See the resources that follow to learn more about how to implement this control.
NIST supplemental guidance
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.
