NIST Sp 800-53 Au-2 Event Logging Au-6 Audit Review
The nist sp 800 53 au 2 event logging au 6 audit review rules tell teams to pick key events and check those logs often. Engineering teams meet these rules when they record every user command and review those logs for risks. Many security rules ask for clear proof of system use. You must decide what to record before a security problem happens. Then you must read those records on a set schedule. If you only store logs and never read them, you fail the audit.

Control AU-2 tells your team to choose which system events need logging. You cannot log every small detail without filling up your storage fast. Instead, you pick events that matter for system safety and data privacy. These events include user log in tries, role changes, and database queries.
Control AU-6 tells your team to look at those logs and report strange activity. Your team must check the records on a regular schedule. You also need to connect records from different servers and databases. This gives you a full picture of what a user did during a session.
Auditors want to see both your written rules and your real log records. They check that you update your list of logged events each year. They also ask for proof that your security team reads the reports. Strong event logs also provide proof for SOC 2 Type II, HIPAA, GDPR, PCI DSS, SOX, ISO 27001, and FedRAMP reviews.
Why role checks need runtime command logs and data masking
Most teams set up user roles in an identity tool and check them each quarter. Still, role checks only show what a person could do in theory. They do not show what commands a user ran on a live system. Shared database accounts make this problem much worse for audit teams.
When five developers share one admin login, the database log hides who ran a command. To meet AU-2 and AU-6, every log entry must tie back to one real person. Runtime command logs solve this problem by recording the user email with each query or shell command. Reviewers can then see the exact actions taken during a support session.

Logging every query and result can create a new risk for private data. If a log captures raw customer data, the log file becomes a target. Response masking fixes this issue before data reaches the screen or the log. Masking rewrites matched fields in results, such as emails, phone numbers, card numbers, and national IDs.
How to run weekly log reviews with your team
A good log review process does not need to take all week. Start by grouping your logs by high-risk actions, like schema changes or bulk data reads. Send alerts to your security chat when someone runs a destructive command. This helps your team spot mistakes or attacks right away.
Next, hold a short weekly meeting to check unusual access patterns. Look for commands run outside normal work hours or from new locations. Write down what you checked and save a ticket as audit proof. When the auditor arrives, your team will have clear records ready to share.
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-6?
AU-2 requires you to define which security events your systems will record. AU-6 requires your team to review, analyze, and report on those recorded logs.
How often should teams review event logs for AU-6?
NIST lets each team set its own schedule based on system risk. Most engineering teams use daily alerts for high risks and run weekly human reviews.
How do we keep sensitive data out of audit logs?
Use response masking to rewrite private fields like card numbers and emails at runtime. This keeps sensitive values out of query results and log files.
