Meeting iso 27001 compliance section 18 means your team must follow all laws and contracts. Engineering teams meet this standard by logging system actions and running regular security checks.
In the 2013 version of the standard, Annex A.18 covers legal and contractual rules. It also requires independent reviews and technical checks on your apps and databases. Even as teams update to newer editions, auditors still ask for these core controls. You must show which laws apply to your data and how you protect it.
What auditors check for iso 27001 compliance section 18
Auditors divide this section into two main parts during a review. The first part focuses on legal rules, data privacy, and intellectual property. You must list every law and contract that governs your system and customer data. This list often includes GDPR, HIPAA, PCI DSS, or local privacy laws.
Privacy and protection of personal data sit at the center of this check. Auditors want proof that you guard emails, phone numbers, and card numbers in databases. You also need clear records protection so audit logs cannot be changed or deleted. Intellectual property rules require you to track software licenses across your whole team.
The second part of Annex A.18 covers security reviews and technical checks. Managers must review team policies on a set schedule to see if they work. Independent auditors must also test your controls and report any gaps they find. Technical compliance checks verify that servers and databases match your written security rules.
Why identity rules need command logs and data masking
Static role lists and quarterly reviews do not show what happens during live work. An engineer might hold valid database permissions for a daily support task. A role check shows who can log in, not what queries they run. Auditors reviewing legal and privacy controls want to see actual command logs.
Command and query logs tie every action to a single person on your team. When an engineer reads a database table, the log records the exact statement. This creates clear proof for records protection and technical reviews under Annex A.18. You do not have to guess what happened during an incident or maintenance window.

Data masking helps teams meet the privacy rules in Section 18.1.4 during daily work. Masking rewrites matched fields in results, such as national IDs, emails, and card numbers. Engineers can fix bugs and run checks using safe, masked output. Your team lowers privacy risks while keeping full query logs for the next audit.
How to run technical checks without blocking down work
Many teams treat compliance checks as a mad dash right before the audit starts. They pull screenshots by hand and dig through old tickets for approval proof. This manual work takes days away from building product features and fixing bugs. A better plan builds evidence collection right into daily engineering workflows.
Start by writing down a simple map of your data and legal rules. Link each database and server group to the privacy or contract rules it falls under. Next, make sure every production query or command leaves a clean, searchable log. Include the user identity, the time, the target system, and the command text.
Set up peer approvals for high-risk tasks on production systems. When a developer needs to run a sensitive command, another team member approves it. The system logs both the approval and the command in the same record. When the auditor arrives, you can export these records in minutes.
Govern statements and responses across databases and APIs
Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev runs beside each supported service as an open-source proxy, a sidecar for your database or API.
First, hoop.dev guardrails block banned queries before they run. Then hoop.dev data masking rewrites matched sensitive values in responses in memory. The audit trail records every statement and verdict per resource. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
What are the two main parts of ISO 27001 Annex A.18?
Section 18.1 covers legal and contractual rules, including intellectual property, records, and personal data privacy. Section 18.2 covers independent security reviews, policy checks by managers, and technical system checks.
How did Annex A.18 change in the 2022 version of ISO 27001?
The 2022 update merged the four themes of the 2013 version into Organizational controls. You will now find the old Section 18 rules under Annex A.5 controls, like A.5.31 through A.5.36.
What proof do auditors want for personal data protection in Section 18?
Auditors ask for your privacy policy, a data register, and proof of technical controls. Logs of database queries and active data masking rules for emails or card numbers work well.
