1.0 Introduction

1.1 Purpose

This document defines the requirements for the Security Audit Trail feature. For security, compliance, and incident investigation purposes, the system must create an immutable log of security-sensitive events. This feature provides an interface for authorized administrators to review these logs, enabling them to monitor user activity and administrative actions within the application.

2.0 Business Requirements

2.1 Audit Log Viewer

Authorized administrators must have access to a dedicated "Audit Trail" page to view all recorded security events.

  • 2.1.1 Log Display: The audit trail must be displayed in a clear, reverse-chronological order (newest events first). Each log entry must display, at a minimum:
  • Timestamp (in a human-readable format, with timezone)
  • Actor (the user who performed the action)
  • Event Type (a clear, consistent identifier for the action)
  • Target (the user or entity that was affected by the action)
  • Key Details (a brief summary of the event)
  • 2.1.2 Filtering and Searching: The interface must provide functionality to filter the audit log by:
  • A specific date range.
  • A specific user (as either the Actor or the Target).
  • A specific Event Type.
  • 2.1.3 Pagination: The audit trail must be paginated to ensure performance and usability when dealing with a large volume of log entries.

2.2 Auditable Events

The system must automatically record a log entry whenever one of the following security-sensitive events occurs. The log must capture who performed the action, on whom, and when.

  • Authentication Events:
  • USER_LOGIN_SUCCESS: A user successfully authenticates via the Google SSO callback.
  • USER_LOGIN_FAILURE: A user login attempt fails (e.g., due to a non-corporate account, canceled flow, or an inactive system account).
  • USER_LOGOUT: A user logs out of the application.
  • User Provisioning Events:
  • USER_PROVISIONED: A new user account is created via the Just-In-Time (JIT) provisioning process on their first successful login.
  • USER_INVITED: An administrator pre-provisions a user account using the "Invite User" functionality.
  • Administrative Actions:
  • USER_STATUS_CHANGED: An administrator changes a user's status (e.g., from Active to Inactive). The log details must include the old and new status.
  • USER_ROLE_ASSIGNED: An administrator assigns a role to a user. The log details must include the name of the role.
  • USER_ROLE_UNASSIGNED: An administrator removes a role from a user.
  • USER_GROUP_ASSIGNED: An administrator adds a user to a group.
  • USER_GROUP_UNASSIGNED: An administrator removes a user from a group.

3.0 Business Rules

  • Rule 10.1: An administrator must possess the admin:audit:view permission to access the "Audit Trail" page.
  • Rule 10.2: Audit logs must be immutable. The system must not provide any functionality for users, including administrators, to edit or delete log entries.
  • Rule 10.3: The timestamp for all audit events must be recorded in a standardized format, such as UTC, to ensure consistency.

4.0 Scope

4.1 In Scope

  • Backend logic to automatically capture and store the defined auditable events.
  • Administrative UI for viewing, filtering, and paginating the audit trail.
  • Access control for the audit trail viewer.

4.2 Out of Scope

  • Real-time alerting or notification based on audit events.
  • Functionality for exporting, archiving, or rotating audit logs.
  • The user actions that trigger the events (these are defined in their respective feature documents).

5.0 Assumptions and Dependencies

  • 5.1: The administrator viewing the audit trail is authenticated and has the necessary permissions.
