Requirements NIST SOURCE

Prohibit processes from executing without supervision for more than [time period].

Discussion (NIST Supplemental Guidance)

Placing a time limit on process execution without supervision is intended to apply to processes for which typical or normal execution periods can be determined and situations in which organizations exceed such periods. Supervision includes timers on operating systems, automated responses, and manual oversight and response when system process anomalies occur.

Engineering Interpretation

No engineering interpretation has been authored for SI-7(16) yet. This section is architected to receive it — see the Requirements and Assessment sections above for the authoritative NIST source content in the meantime.

Assessment

NIST SP 800-53A REV 5.2.0

Assessment Objectives

  1. the maximum time period permitted for processes to execute without supervision is defined;
  2. processes are prohibited from executing without supervision for more than <SI-07(16)_ODP time period>.

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SI-7(16). 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.
