Authentication logging for compliance: what events to capture

In today's digital landscape, maintaining robust security measures is not just a necessity; it's a requirement for any organization serious about protecting its assets and data. One critical aspect of this is ensuring that your authentication processes are not only secure but also compliant with various regulatory standards. This blog post will delve into the key events you should log for authentication to meet compliance requirements, ensuring that your Bastionary implementation is up to par.

Understanding Authentication Events

Authentication events are the various activities that occur during the process of verifying a user's identity. These events can range from simple login attempts to more complex scenarios like multi-factor authentication (MFA) and privilege escalations. Capturing the right events and retaining them for the appropriate amount of time is crucial for both security and compliance. Let's explore what these events are and why they matter.

Login Success/Failure Events

Every time a user attempts to log in, whether successfully or not, this event should be logged. This includes details such as the username, timestamp, IP address, and the outcome of the attempt. These logs are invaluable for detecting unauthorized access attempts and for auditing purposes.

event: login_attempt
      fields: username, timestamp, IP_address, success

Key Insight: Even failed login attempts can be a sign of a security breach attempt and should be logged for further investigation.

MFA Events

Multi-factor authentication adds an extra layer of security by requiring users to provide two or more verification factors to gain access to a resource. Logging MFA events is essential for compliance, as it helps demonstrate that additional security measures are in place. This includes the type of MFA used, the time it was initiated, and the outcome of the attempt.

event: mfa_attempt
      fields: username, timestamp, MFA_type, success

Session Creation/Revocation Events

When a user session is created or revoked, this event should be captured. This includes details such as the session ID, the user's identity, and the time of creation or revocation. These logs are crucial for understanding user activity and for identifying potential security threats.

event: session_create
      fields: session_id, username, timestamp
      event: session_revoke
      fields: session_id, username, timestamp

Warning: Ensure that session logs are retained for the required period to comply with security standards.

Password Changes

When a user changes their password, this event should be logged. This includes the old password, the new password, and the timestamp of the change. These logs are important for tracking access patterns and detecting potential security breaches.

event: password_change
      fields: username, old_password, new_password, timestamp

Privilege Escalations

Privilege escalation occurs when a user gains access to resources or permissions beyond their original authorization. Logging these events is essential for maintaining a secure environment and for auditing purposes. This includes details such as the user's identity, the resources accessed, and the time of the escalation.

event: privilege_escalation
      fields: username, resource, timestamp

Key Insight: Privilege escalation events can be a sign of a security breach and should be investigated promptly.

How Long to Retain Authentication Logs

While it's important to capture the right events, it's equally important to know how long to retain these logs. The retention period can vary depending on the regulatory requirements and the specific needs of your organization. Generally, it's recommended to retain authentication logs for at least 90 days, but this can be longer in certain cases.
