What nist sp 800 53 audit logging au 2 au 12 requires from teams
Control AU-2 asks your team to list which events need logging. You must pick actions that matter for security and system health. These events include log in tries, role changes, and data reads.
Control AU-12 focuses on how your systems build those audit records. Every log entry must show what happened, when it ran, and who did it. Auditors check that you turn on logging across all key databases and servers.
Strong logs help you pass many audits at the same time. The same command logs build proof for SOC 2 Type II, HIPAA, GDPR, and PCI DSS. They also support SOX, ISO 27001, and FedRAMP reviews with clear history.
Auditors do not just want to see a written logging policy. They ask for sample logs from production systems during your review window. If two engineers share one database user, the log fails the identity check.
Why role reviews need runtime command logs and data masking
Setting up single sign-on and running quarterly role reviews is a good start. Still, role lists only show who could run a command on a server. They do not show what queries a person ran during an active session.
Runtime command and query logs close this gap for security managers. You see the exact SQL statements or shell commands tied to an email address. When an incident happens, your team can trace the exact steps in minutes.

Logging every query can create a new risk if raw data enters the log. Sensitive fields can spill into log files or show up on engineer screens. Response masking solves this problem by rewriting matched fields in query results.
For example, masking replaces emails, phone numbers, card numbers, and national IDs in results. Engineers still run their queries and fix bugs, while private fields stay masked. Auditors see that you log every action and protect private data at once.
How to scope systems for AU-2 and AU-12 reviews
Start by listing every database, cloud console, and server that holds sensitive data. Map out how engineers and support staff log in to these systems today. Look for shared admin keys or local accounts that bypass your identity provider.
Next, define the exact events you must capture under your AU-2 list. Focus on human sessions, privilege changes, schema edits, and bulk data reads. Make sure your clocks sync across servers so timestamps match during an audit.
Finally, store your AU-12 records in a central place where users cannot edit them. Review your event list once a year or after major system changes. Clear, tamper-proof logs turn stressful audit weeks into a simple file export.
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 is the main difference between NIST AU-2 and AU-12?
AU-2 is the policy step where you decide which security events to track. AU-12 is the technical step where systems create and record those log entries.
Do shared database accounts fail AU-12 audit checks?
Yes, shared accounts make it impossible to prove which person ran a specific query. Auditors expect every log record to trace back to one verified user identity.
How often should teams review their AU-2 logged event list?
Most teams review their list of logged events at least once a year. You should also update the list when you add new databases or handle incidents.
