Australian Information Security Manual ISM-1633: System boundary, criticality and objectives

System owners, in consultation with each system's authorising officer, determine the system boundary, business criticality, and security and resilience objectives for each system based on an assessment of the impact if it were to be compromised or attacked.

What else in your programme already covers this

This control maps to 3 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.

NIST Cybersecurity Framework 2.0 · 3 controls

  • NIST-CSF-GV.OC-04 Critical objectives, capabilities, and services that external stakeholders depend on or expect from the organization are understood and communicated
  • NIST-CSF-ID.AM-05 Assets are prioritized based on classification, criticality, resources, and impact on the mission
  • NIST-CSF-ID.RA-04 Potential impacts and likelihoods of threats exploiting vulnerabilities are identified and recorded

Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
