Basic Auth String

Service Name: HTTP Basic Authentication

Service Description: HTTP Basic Authentication is a simple authentication scheme built into the HTTP protocol. It uses a base64-encoded string containing the username and password, sent in the Authorization header of HTTP requests.

Service Address: Not applicable (used across various web services)

Validation Type: API Auth

IP Allow list: Does not exist at the protocol level, but can be implemented at the server level through firewall rules or application configurations.

Secret Access Scope: Grants access to protected resources on web servers or APIs that implement HTTP Basic Authentication.

Secret Revokement URL: Does not exist (managed by changing credentials on the server)

Secret Example: Authorization: Basic dXNlcm5hbWU6cGFzc3dvcmQ= (where dXNlcm5hbWU6cGFzc3dvcmQ= is base64 encoded username:password)

Suspicious Activity Investigation Instructions:

  • Review server access logs for unusual IP addresses or request patterns using this authentication.
  • Check for increased frequency of requests or access attempts from unexpected locations.
  • Monitor for access to sensitive endpoints or resources that wouldn't normally be accessed.
  • Look for brute force attempts with multiple failed authentications.
  • Examine timestamps of access to identify off-hours usage.

Mitigation Instructions:

  • Change the username and password immediately on all affected systems.
  • Consider implementing stronger authentication methods like OAuth, API keys, or multi-factor authentication.
  • Implement rate limiting to prevent brute force attacks.
  • Enable HTTPS to prevent credential interception through man-in-the-middle attacks.
  • Consider implementing IP restrictions if appropriate for your use case.
  • Review and update access control policies to follow the Principle of Least Privilege.
  • Consider implementing token expiration if continuous authentication is not required.
