NIST-SC-23(3) Unique System-generated Session Identifiers
- Framework
- NIST SP 800-53 rev5 (5.2.0)
- Family
- SC System and Communications Protection
- Control
- SC-23(3)
Control statement
Generate a unique session identifier for each session with [Assignment: randomness requirements] and recognize only session identifiers that are system-generated.
Discussion
Generating unique session identifiers curtails the ability of adversaries to reuse previously valid session IDs. Employing the concept of randomness in the generation of unique session identifiers protects against brute-force attacks to determine future session identifiers.
