Brute force attack
what is it?
(dictionary and password)
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. Depending on password strength, computer programs used for brute force attacks can check anywhere from 10,000 to 1 billion passwords per second.
Some common examples of
brute force attacks:
Hackers use automation and scripts to guess passwords. Typical brute force attacks make a few hundred guesses every second. Simple passwords, such as those lacking a mix of upper- and lowercase letters and those using common expressions like '123456' or 'password,' can be cracked in minutes.
How do dictionarys assist in
brute force attacks:
Hackers use dictionaries when commiting a 'dictionary attack'. This is a type of brute force attack where an intruder attempts to crack a password-protected security system with a 'dictionary list' of common words and phrases used by businesses and individuals.
How to prevent from
brute force attacks:
The most obvious way to block brute-force attacks is to simply lock out accounts after a defined number of incorrect password attempts. Also, the best defense against password attacks is ensuring that your passwords are as strong as they can be.
