Authentication server definition
An authentication server is what determines whether a person or another server is who or what they say they are. Authentication is usually done through credentials — a client submits logins, and they’re either granted or denied access to a service.
Real authentication server examples
One of the most common examples of authentication is logging in to a website with credentials like an email address and a password.
Authentication server cyber attacks
Brute force: the attacker tries thousands of random combinations until they guess the password.
Credential stuffing: the attacker tries credentials from previously leaked databases to see if they match other services.
Stopping an authentication attack
- Make sure you have unique, complicated, and long passwords.
- Always make sure that your connection is secure.
- Don’t click on unknown links.
- Use a VPN.
