# Audit trail

## What Is an Audit Trail in Security and Compliance?

An Audit Trail is a chronological, tamper-resistant record of actions taken within a system, such as user logins, configuration changes, approvals, or data access events. It serves as a traceable activity log that shows who performed an action, what they did, when it occurred, and sometimes how it was authorized. Audit Trails are essential for trust, accountability, and investigation.

## Why Audit Trails Matter

```json
{
  "_key": "2c0268ad5409f331",
  "_type": "tableBlock",
  "firstRowIsHeader": true,
  "markDefs": null,
  "table": {
    "rows": [
      {
        "_key": "1ac5f8578aff3dd5",
        "_type": "tableRow",
        "cells": [
          "Purpose",
          "Example"
        ]
      },
      {
        "_key": "7c3bb01a9a5f373c",
        "_type": "tableRow",
        "cells": [
          "Security Monitoring",
          "Detect suspicious behavior"
        ]
      },
      {
        "_key": "83fb634d5075891f",
        "_type": "tableRow",
        "cells": [
          "Compliance Audits",
          "Meet ISO, SOC 2, PCI requirements"
        ]
      },
      {
        "_key": "100c939f65ae50cc",
        "_type": "tableRow",
        "cells": [
          "Forensic Investigation",
          "Trace the root cause of incidents"
        ]
      },
      {
        "_key": "1c0209df3222282e",
        "_type": "tableRow",
        "cells": [
          "Internal Governance",
          "Verify policy enforcement"
        ]
      },
      {
        "_key": "f7ace48aa61d6c55",
        "_type": "tableRow",
        "cells": [
          "Operational Insight",
          "Monitor system usage"
        ]
      }
    ]
  }
}
```

Without Audit Trails, investigations rely on guesswork rather than evidence.

## How Audit Trails Work

A well-designed Audit Trail records:

- User identity
- Timestamp
- Action taken
- System or resource affected
- Source device or location
- Outcome or status

Logs are stored securely so they cannot be modified without detection.

## Where Audit Trails Are Used

Audit Trails are common in:

- Banking and financial technology
- Healthcare systems
- Government systems
- SaaS platforms
- Cloud infrastructure
- Identity and access systems

Anywhere accountability matters, audit trails are required.
