Brute-force Attacks
If attacker want to crack a password then he can crack any passwords by Brute-force attacks he has to try every possible combination of letters, numbers, and special characters until he succeeded . This is a time taking method it actually depends on the efficiency of the processor of your computer
This
attack is actually based on hit and trial method used to obtain information such as a
user password or personal identification number (PIN). In a brute force
attack, automated programs ,scripts and codes is used to generate a large number of
consecutive guesses as to the value of the desired data. Brute force
attacks may be used by criminals to crack encrypted data, or by security
analysts to test an organization's network security.
The following measures can be used to defend against brute force attacks:
- Requiring users to have complex passwords
- Limiting the number of times a user can attempt to log in
- Temporarily locking out users who exceed the specified maximum number of login attempts
