Requirements NIST SOURCE

Automatically update spam protection mechanisms [frequency].

Discussion (NIST Supplemental Guidance)

Using automated mechanisms to update spam protection mechanisms helps to ensure that updates occur on a regular basis and provide the latest content and protection capabilities.

Implementation Guidance

Engineering Interpretation

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

No engineering interpretation has been authored for SI-8(2) 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 frequency at which to automatically update spam protection mechanisms is defined;
  2. spam protection mechanisms are automatically updated <SI-08(02)_ODP frequency>.

Examine

[SELECT FROM: System and information integrity policy; system and information integrity procedures; procedures addressing spam protection; spam protection mechanisms; records of spam protection updates; system design documentation; system configuration settings and associated documentation; system audit records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: Organizational personnel responsible for spam protection; organizational personnel with information security responsibilities; system/network administrators; system developer].

Test

[SELECT FROM: Organizational processes for spam protection; mechanisms supporting and/or implementing automatic updates to spam protection mechanisms].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SI-8(2). 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.
