# Groupware Security Blocking

To protect the [[groupware]] from brute-force attacks, the system implements an IP-based security mechanism.

## IP Lockout Policy
If multiple failed login attempts are made from a single computer or IP address within a short period, access to the Groupware website is automatically blocked for that specific IP address.

- **Duration**: 30 minutes.
- **Effect**: The user will be unable to reach the login page from the blocked device, even if they subsequently discover the correct credentials.
- **Verification**: If a user can access the site from a different device but not their primary one, it is likely an IP lockout.
