Non-persistent Connectivity
LOW MODERATE HIGHRequirements NIST SOURCE
Establish connections to the system on demand and terminate connections after [one of: completion of a request; a period of non-use].
Discussion (NIST Supplemental Guidance)
Persistent connections to systems can provide advanced adversaries with paths to move laterally through systems and potentially position themselves closer to high value assets. Limiting the availability of such connections impedes the adversary’s ability to move freely through organizational systems.

Assessment
Assessment Objectives
- one of the following PARAMETER VALUES is selected: {completion of a request; a period of non-use};
- connections to the system are established on demand;
- connections to the system are terminated after <SI-14(03)_ODP SELECTED PARAMETER VALUE>.

STIGs & CCIs
No STIG checks or CCI mappings are currently loaded for SI-14(3). This section is architected to display, per product: STIG ID, Finding ID, Severity, Title, Description, Check, Fix, CCI, and NIST control mapping — but nothing is populated here until a real DISA STIG/CCI dataset is ingested.
