ISO 27001 Annex A controls

Annex A, read as a working list of 93 controls.

Annex A is the part of ISO/IEC 27001:2022 people open first and understand last. It is a reference list: 93 controls, each with a number and a name, grouped into four themes. Below, every control gets a one-line summary in our own words. Use it to see what each name covers, then settle what applies through your risk work and record that in the Statement of Applicability (SoA).

01 · Reading the list

Before you read the 93: three things to know

The list is sparing with words by design. Three facts about it head off most misreadings.

A number is a theme plus a position
8.13 is the thirteenth control in theme 8. Themes run from 5 to 8 because the numbering mirrors ISO/IEC 27002, whose first four clauses are introductory.
The name is nearly all you get here
Annex A states each control briefly. The longer explanation sits in ISO/IEC 27002, a separate guidance standard.
Selection starts from risk
Under clause 6.1.3 you choose controls to treat your risks, from any source, then hold them up against Annex A so nothing needed slips through. The list is a cross-check, not an order to adopt every line.
ThemeRangeControlsEvidence usually comes from
Organizational5.1 to 5.3737Policies, registers, contracts and incident files
People6.1 to 6.88HR files, signed agreements and training records
Physical7.1 to 7.1414Site walk-throughs, visitor logs and disposal records
Technological8.1 to 8.3434System settings, logs, tickets and test results

Each theme has its own deeper page on this site, with a typical setup and the evidence an auditor asks for, control by control. The cards under each list below lead there.

02 · Theme 5: Organizational

Theme 5, organizational: 37 controls

Rules, ownership and relationships: policy, assets, access rules, vendors, incidents, continuity and legal duties. It holds 37 of the 93 controls, and a Stage 1 document review spends most of its time here.

05 · Theme 8: Technological

Theme 8, technological: 34 controls

How systems enforce the rules: devices, identities, vulnerabilities, settings, data handling, logs, networks, encryption and the way software is built. Stage 2 sampling draws heavily on this theme.

06 · Changes since 2013

How the 2022 list differs from the 2013 one

The 2022 edition rebuilt the list rather than adding to it. Fewer controls, fewer groups, and eleven topics with no earlier counterpart.

2013 edition

  • 114 controls
  • 14 control groups, numbered A.5 to A.18
  • No attribute tags in the companion guidance

2022 edition

  • 93 controls
  • 4 themes, numbered 5 to 8
  • Many older controls folded together under one name
  • 11 controls with no 2013 predecessor

The eleven additions

  • 5.7 Threat intelligence
  • 5.23 Information security for use of cloud services
  • 5.30 ICT readiness for business continuity
  • 7.4 Physical security monitoring
  • 8.9 Configuration management
  • 8.10 Information deletion
  • 8.11 Data masking
  • 8.12 Data leakage prevention
  • 8.16 Monitoring activities
  • 8.23 Web filtering
  • 8.28 Secure coding

Most of the drop in count came from merging related controls rather than deleting them. The additions cover areas that grew in weight while the 2013 edition was current, such as cloud use, awareness of live threats and data slipping out of the organisation. Certificates to the 2013 edition reached the end of their transition period on 31 October 2025.

Sources: ISO/IEC 27001:2022, Annex A (control numbers and titles only) and clause 6.1.3 (title only); ISO/IEC 27002:2022 (theme structure); IAF MD 26 on the transition to ISO/IEC 27001:2022. Every control summary on this page is Auditify's own wording, not text from either standard.

Questions about the control list

Why does Annex A start at 5 and not at 1?

Its numbering follows the clauses of ISO 27002.

In ISO/IEC 27002, clauses 1 to 4 cover scope, references, terms and structure, and the controls begin at clause 5. Annex A keeps those numbers so the two documents line up exactly.

Our customer's framework has controls Annex A lacks. Where do they go?

Into your risk treatment and SoA, beside the Annex A ones.

Controls may come from any source. Add the extra ones to your risk treatment plan and list them in the SoA alongside the 93, so an auditor can see what each one treats. Annex A still serves as the check that nothing standard was missed.

Which theme takes the most effort?

Organizational by count, technological by evidence.

Theme 5 has the most controls and most of the written rules. Theme 8 produces the most day-to-day records, such as logs, tickets and scan results, and that is where Stage 2 sampling tends to linger.

Do cloud-only companies still need physical controls?

Usually some, for offices, laptops and media.

Data-centre protection rests with the provider, and you rely on its own assurance for that. Your offices, home workers, laptops and old devices still sit in theme 7, so expect to keep several of its controls.

Where is each control explained in depth?

In ISO 27002, and on our theme pages.

ISO/IEC 27002 is the official guidance for every control. Our four theme pages add a typical setup and the evidence an auditor asks for, in our own words.

Turn 93 names into a short list you can defend.

An ISO 27001 gap analysis from Auditify compares what you run today with each Annex A control and helps you draft the SoA decisions and the reasons behind them.
