Requirements NIST SOURCE

Remove the following information from online storage and store offline in a secure location: [information].

Discussion (NIST Supplemental Guidance)

Removing organizational information from online storage to offline storage eliminates the possibility of individuals gaining unauthorized access to the information through a network. Therefore, organizations may choose to move information to offline storage in lieu of protecting such information in online storage.

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-28(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. information to be removed from online storage and stored offline in a secure location is defined;
  2. <SC-28(02)_ODP information> is removed from online storage;
  3. <SC-28(02)_ODP information> is stored offline in a secure location.

Examine

[SELECT FROM: System and communications protection policy; procedures addressing the protection of information at rest; system design documentation; system configuration settings and associated documentation; cryptographic mechanisms and associated configuration documentation; offline storage locations for information at rest; system audit records; system security plan; other relevant documents or records].

Interview

[SELECT FROM: System/network administrators; organizational personnel with information security responsibilities].

Test

[SELECT FROM: Mechanisms supporting and/or implementing the removal of information from online storage; mechanisms supporting and/or implementing storage of information offline].

STIGs & CCIs

No STIG checks or CCI mappings are currently loaded for SC-28(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.
