Brute force attack also known as exhaustive key search attack, in which the encrypted data or messages are hacked, and then with the use of software they are broken down to acquire the messages, user IDs and passwords. Once a hacker is able to gain the access of the privileged authority, he/she can install a back door for future use even if the passwords or the user IDs keep changing.
- To secure the passwords and the other sensitive data, implement unbreakable encryption technology and also preserve the keys safely.
- Keep the passwords long and keep changing them from time to time.
- Frequently scan or test the system to detect vulnerability.
- Literate users about security precautions.
