  SC-10: Network Disconnect  

base control objective:
The information system terminates the network connection associated with a communications session at the end of the session or after [Assignment: organization-defined time period] of inactivity.

supplemental objective information:
This control applies to both internal and external networks. Terminating network connections associated with communications sessions include, for example, de-allocating associated TCP/IP address/port pairs at the operating system level, or de-allocating networking assignments at the application level if multiple application sessions are using a single, operating system-level network connection. The time period of inactivity may, as the organization deems necessary, be a set of time periods by type of network access or for specific accesses.

enhancements to the base objective:

(1) None.

mapping to FIPS199 baseline:

  LOW: null     MOD: base     HIGH: base  

related (regimented) controls:

None.
