A brute force attack uses trial-and-error to guess login info, encryption keys, or find a hidden web page. Hackers work through all possible combinations hoping to guess correctly.
Is brute force safe?
256-bit encryption is one of the most secure encryption methods, so it's definitely the way to go. 256-bit encryption crack time by brute force requires 2128 times more computational power to match that of a 128-bit key.
Can brute force be detected?
Detecting brute force attacks
The factor that will hold true for any authentication brute force attack is a large number of failed authentication attempts. However, since the user cannot be the key for detection, a detection system has to focus on another key to connect the thread of events making up the attack.
