ISO 27001 User Access Review
An iso 27001 user access review checks who can reach your company systems and data. Engineering teams meet this rule by checking user roles and removing old accounts on a schedule. Security managers run these checks to stop data leaks and pass yearly audits. When people change jobs or leave, their old permissions often stay active by mistake. A clear review process finds those extra rights and removes them fast. This guide covers what auditors look for and how runtime logs make reviews simple.

Scope and evidence for an iso 27001 user access review
The ISO 27001 standard asks teams to check access rights at planned times. You must also check rights right away when a person changes roles. Auditors look at every system that holds sensitive data or runs production code. This includes databases, cloud consoles, servers, and internal tools.
During an audit, you must show proof that your review happened on time. Auditors ask for a full list of active users and their current roles. They compare this list against your human resources roster of active staff. If a former worker still has an active account, the auditor flags a gap.
Privileged roles get the closest look during an audit check. Admin accounts can change rules, delete data, or read private records. You need to show who approved each admin role and why that person needs it. Teams must also record the exact date when a manager checked and signed off on the list.
Static spreadsheets make this work slow and hard to track over time. Managers often rubber-stamp long lists of roles because they lack context on daily usage. Good audit evidence pairs role lists with real activity records from your systems. This approach also supports SOC 2, HIPAA, GDPR, PCI DSS, SOX, and FedRAMP audits.
Why identity setup and reviews need command logs and masking
Identity providers show which groups a user belongs to on paper. Still, group lists do not show what a user does inside a database or server. Shared database accounts make this gap even worse for security teams. When five devs share one login, you cannot tell who ran a specific command.
Runtime command logs solve this problem by tying every action to a single person. When you review permissions, you can check when a user last ran a query. If an engineer has not touched a production database in six months, you can drop that role. Activity logs turn guesswork into clear facts during your quarterly check.

Approval workflows also cut down the number of standing admin roles you must review. Instead of giving permanent write rights, teams can require a peer check for big changes. Each approval creates a clean record with the user name, time, and reason. Auditors love seeing that sensitive tasks need a fresh sign-off every time.
Data masking adds another layer of safety for users who do need read rights. Even when a support engineer needs to run queries, they do not need raw customer details. Masking rules rewrite matched fields like emails, phone numbers, card numbers, and national IDs in results. This lowers your risk exposure while keeping daily work moving forward.
How to build a repeatable review schedule
Start by listing every data store and server in your production setup. Assign one system owner to each resource on your list. That owner knows who should have read or write rights for their team.
Set a calendar reminder to check admin roles every ninety days. Regular user roles can follow a six-month schedule if risk is low. Pull your identity list and your recent command logs before the meeting starts.
Ask each manager to check their team members and sign off in writing. Revoke any unused permissions on the same day you find them. Save the before and after lists in a central folder for your next audit.
Check database and API queries on the wire
Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.
Frequently asked questions
How often does ISO 27001 require a user access review?
The standard does not set one fixed calendar schedule for every company. Most auditors expect teams to check high-risk admin roles every quarter and standard roles twice a year.
What happens if an auditor finds an active account for a former employee?
The auditor will record a finding against your access control rules. You will need to disable the account, check logs for recent activity, and fix your offboarding process.
Should service accounts be part of our access review process?
Yes, automated scripts and app keys often hold high permissions in production. Teams must review who owns each key, what data it touches, and when it was last rotated.
