Sub-clause map

  • 6.1 Actions to address risks and opportunities
    • 6.1.1 General โ€” actions to address risks and opportunities considered when planning the ISMS.
    • 6.1.2 Information security risk assessment โ€” define and apply a process.
    • 6.1.3 Information security risk treatment โ€” define and apply a process, produce a Statement of Applicability, get risk-owner approval of the treatment plan and acceptance of residual risk.
  • 6.2 Information security objectives and planning to achieve them.
  • 6.3 Planning of changes โ€” new in :2022.

Key "shall" requirements (verbatim selections from :2022)

  • 6.1.2: the org "shall define and apply an information security risk assessment process that:
    • a) establishes and maintains information security risk criteria that include:
      • 1) the risk acceptance criteria;
      • 2) criteria for performing information security risk assessments;
    • b) ensures that repeated information security risk assessments produce consistent, valid and comparable results;
    • c) identifies the information security risks: ... apply the risk assessment process to identify risks associated with the loss of confidentiality, integrity and availability for information within the scope of the information security management system; identify the risk owners;
    • d) analyses the information security risks: ... assess the potential consequences ... assess the realistic likelihood ... determine the levels of risk;
    • e) evaluates the information security risks: ... compare the results of risk analysis with the risk criteria ... prioritize the analysed risks for risk treatment."
  • 6.1.3: the org "shall define and apply an information security risk treatment process to:
    • a) select appropriate ... risk treatment options ...
    • b) determine all controls that are necessary to implement the information security risk treatment option(s) chosen;
    • c) compare the controls determined in 6.1.3 b) above with those in Annex A and verify that no necessary controls have been omitted;
    • d) produce a Statement of Applicability that contains:
      • the necessary controls ... and justification for their inclusion;
      • whether the necessary controls are implemented or not;
      • the justification for excluding any of the Annex A controls;
    • e) formulate an information security risk treatment plan;
    • f) obtain risk owners' approval of the information security risk treatment plan and acceptance of the residual information security risks."
  • 6.2: objectives shall "be consistent with the information security policy; be measurable (if practicable); take into account applicable information security requirements, and results from risk assessment and risk treatment; be monitored; be communicated; be updated as appropriate; be available as documented information."
  • 6.3: "When the organization determines the need for changes to the information security management system, the changes shall be carried out in a planned manner."

Changes from :2013

  • 6.3 Planning of changes is new. Previously planning of ISMS changes was implicit in 8.1 operational planning. :2022 surfaces it as a standalone clause, aligned with Annex SL update.
  • 6.1.3.c wording tightened โ€” "compare the controls determined ... with those in Annex A and verify that no necessary controls have been omitted." :2013 wording was "compare the controls determined in 6.1.3 b) above with those in Annex A and verify that no necessary controls have been omitted." Substance the same; auditor expectation unchanged.
  • 6.2 added subitems "be monitored" and "be available as documented information" (Annex SL alignment).

The Statement of Applicability (SoA)

The SoA is the most-cited single artefact in an ISO 27001 audit. It is a table with one row per Annex A control (all 93 in :2022) listing:

  • Control reference and title.
  • Applicable (yes/no).
  • Justification (if applicable: why; if not applicable: why not).
  • Implementation status (implemented / partially / not yet).
  • Reference to the implementing policy, procedure, or evidence.

The SoA is the bridge between the risk treatment plan (what the org will do) and the Annex A reference list (the recognized control catalog). Excluding controls is permitted; the justification must withstand auditor probing. "We do not handle physical assets" is a valid exclusion for a fully remote SaaS company. "We do not need monitoring" is not.

The SoA also extends beyond Annex A: if 6.1.3.b identifies necessary controls not in Annex A (e.g., AI-system specific controls), those are added to the SoA. Annex A is a floor reference, not a ceiling.

Evidence artefacts an auditor expects

  • Risk assessment methodology document โ€” defines criteria, scales (likelihood, impact), thresholds, and the repeatable process. Cl 6.1.2.b ("consistent, valid and comparable results") is checked by re-running the process and seeing matching outputs.
  • Risk register โ€” actual risks identified, owners assigned, scored, with treatment decisions.
  • Risk treatment plan โ€” for each treated risk: chosen treatment (mitigate / accept / avoid / transfer), controls selected, target date, responsible role.
  • Statement of Applicability โ€” current version, dated, owner identified, including the new :2022 controls.
  • Risk owner approvals โ€” signed or otherwise auditable acceptance of residual risk.
  • Objectives register โ€” measurable security objectives with target values, current values, owner, review cadence. Examples: "phishing simulation click rate < 5% in 12 months," "patch SLA met for 95% of critical CVEs within 7 days," "100% of new agents have documented threat models before production deployment."
  • Change-planning records (new for :2022) โ€” evidence the change is planned (not just executed): change management tickets, architectural review records, security review sign-off.

Typical audit observations

  • Risk register is a control list, not a risk list. Each row reads "lack of MFA," "lack of patching," "lack of training." These are control gaps, not risks. A risk has a threat agent, an asset, a vulnerability, and a consequence. Major nonconformity if pervasive.
  • Risk scoring not repeatable. Two assessors against the same asset arrive at different scores because the criteria are vague. Cl 6.1.2.b finding.
  • SoA exclusions thin. "A.7.4 Physical security monitoring โ€” not applicable, we are remote." Auditor probes: do remote employees have CCTV / smart cameras / door sensors in home offices the company has authorized? The exclusion may need narrowing.
  • SoA out of date. Still on :2013 numbering; A.18.1.4 cited instead of A.5.34 (PII protection). Major nonconformity post-transition-deadline (31 October 2025).
  • Objectives are activities, not outcomes. "Run a phishing exercise" is an activity. "Achieve < 5% click rate" is an outcome. Cl 6.2 expects measurable objectives โ€” outcomes are measurable in the relevant sense.
  • Change planning not visible. A new agent system deployed to production with no documented change record. Cl 6.3 nonconformity.

Common implementation gaps

  • Asset register absent. Risks reference "the production database" without a clear asset list. Cl 6.1.2.c risk identification depends on knowing the assets in scope. Often a Cl 8 or A.5.9 finding feeding back to 6.
  • Risk treatment plan = SoA copy. The treatment plan should be richer than the SoA: it has time-boxed actions, not just controls.
  • Residual risk acceptance is a rubber stamp. Risk owner signs without seeing the residual-after-treatment score. Cl 6.1.3.f expects informed acceptance.
  • Objectives align to certification, not security. "Achieve and maintain ISO 27001 certification" is meta and circular as an objective. Useful objectives speak to risk reduction or capability improvement.

SRE and AI-agent fit notes

  • AI / agent risks belong in the risk register. Examples:
    • Prompt injection causing autonomous agent to exfiltrate data.
    • Model vendor outage cascading into customer-facing service.
    • Agent-generated audit logs being incomplete or tamperable.
    • Tool-use scope creep (an agent given file-read access misused for file-write).
    • Federated workspace synchronization integrity (bd federation between machines).
    • Vendor SaaS API key compromise via developer machine.
  • Risk owners for AI controls. Often unclear. Default to the engineering lead for the system; escalate to CISO / management representative for cross-system concerns.
  • New Annex A :2022 controls especially relevant for AI work:
    • A.5.7 Threat intelligence โ€” covers feeds about AI-specific threats, prompt-injection campaigns, model-supply-chain news.
    • A.5.23 Information security for use of cloud services โ€” covers model-as-a-service vendor relationships.
    • A.8.9 Configuration management โ€” covers model versions, system prompts, agent tool scopes.
    • A.8.10 Information deletion โ€” covers training-data and vendor-side retention.
    • A.8.11 Data masking โ€” relevant when shipping data to model APIs.
    • A.8.12 Data leakage prevention โ€” relevant for AI feature responses and tool-use boundaries.
    • A.8.16 Monitoring activities โ€” covers agent action logging.
    • A.8.28 Secure coding โ€” extended to "secure prompting" and tool-scope definitions.
  • SoA extensions for AI. Add company-specific controls referencing OWASP LLM Top 10, NIST AI RMF profile, or ISO 42001 alignment. Document them as additions to A.5.7, A.8.16, A.8.28 with a clear rationale.

Stefan-context implementation sketch

  • Risk methodology: lightweight, qualitative, with named scoring criteria (low / medium / high on impact and likelihood with explicit definitions per criteria). FAIR-quantitative reserved for high-stakes client risks.
  • Risk register: maintained as a bd query / markdown atom. Linked to vault classification (whiteout-kb/ vs work-kb/ vs client data).
  • SoA: built once against :2022 Annex A; updated when scope, vendor list, or threat model shifts.
  • Objectives: e.g., "vault PII never leaves whiteout-kb classification boundary," "vendor SaaS API keys rotated within 90 days," "agent audit logs retained 12 months and tamper-evident."
  • Change planning: bd issue per significant ISMS change (new vendor, new agent, scope shift, federation peer add).
