NIST SP 800-53 SC-5(3) Detection and Monitoring

Requirements NIST SOURCE

Discussion (NIST Supplemental Guidance)

Organizations consider the utilization and capacity of system resources when managing risk associated with a denial of service due to malicious attacks. Denial-of-service attacks can originate from external or internal sources. System resources that are sensitive to denial of service include physical disk storage, memory, and CPU cycles. Techniques used to prevent denial-of-service attacks related to storage utilization and capacity include instituting disk quotas, configuring systems to automatically alert administrators when specific storage capacity thresholds are reached, using file compression technologies to maximize available storage space, and imposing separate partitions for system and user data.

Engineering Interpretation

Original engineering commentary written for this explorer — not NIST source text and not authoritative guidance.

No engineering interpretation has been authored for SC-5(3) 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

monitoring tools for detecting indicators of denial-of-service attacks are defined;
system resources to be monitored to determine if sufficient resources exist to prevent effective denial-of-service attacks are defined;
<SC-05(03)_ODP[01] monitoring tools> are employed to detect indicators of denial-of-service attacks against or launched from the system;
<SC-05(03)_ODP[02] system resources> are monitored to determine if sufficient resources exist to prevent effective denial-of-service attacks.

Overlays

Showing the OT/ICS overlay for the parent control SC-5 — see the SC-5(3) entries within each baseline below.

OT/ICS Overlay SP 800-82r3

NIST SP 800-82r3 Appendix F, Table 22. Blank baseline means the control/control enhancement is not selected in that initial OT baseline.

LOW

Base control: Included (matches standard baseline)

MODERATE

Base control: Included (matches standard baseline)

HIGH

Base control: Included (matches standard baseline)

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SC-5(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.
