What is a brute force attack?

Brute force attack:
Attempt to crack a password/username using trial and error.

To prevent against brute force attack, the simplest method is to use a random password generator.

A brute force attack is a trial and error method used by application programs to decode encrypted data such as passwords or Data Encryption Standard (DES) keys, through exhaustive effort (using brute force) rather than employing intellectual strategies.

A brute force attack is a trial-and-error method used to obtain information such as a user password or personal identification number (PIN). In a brute force attack, automated software is used to generate a large number of consecutive guesses as to the value of the desired data

Brute force attack is simple method to gain access to a server or a site.
We can prevent this attack by following steps:
1. Using long passwords
2. Limit your login attempts
3. Use two factor athentication
4. Use captcha

This is one of the hacking methods , where a application randomly sends a password and tries to login . It generates thousands of passwords in seconds and tries all. If your password is very common then you have every chance of being hacked .

The brute-force attack is one of the most popular password cracking method. The best way to prevent brute-force attack is to limit invalid login. In this way, attack can only hit and try passwords only for limited times.

Brute Force attack is a technique used by hackers to crack a password of a WiFi, actually it doesn’t fit, it is technique that can crack any password whether its a WiFi password or any other account on the Internet. It is actually an idea to crack a password using every possible combination of letters to form words.

The most common and easiest to understand example of the brute force attack is the dictionary attack to crack passwords. In this, the attacker uses a password dictionary that contains millions of words that can be used as a password. The attacker tries these passwords one by one for authentication.
How to Prevent Brute Force Attacks:
1. Use Strong Passwords
2. Restrict Access to Authentication URLs
3. Limit Login Attempts
4. Use CAPTCHAs
5. Use Two-Factor Authentication (2FA)

Brute force attack is a cryptographic hack, in which hacker tries all possible combinations of password to until it found the correct one.
It is very important to protect your server from brute force attack other wise hacker will get access.

Brute force attacks are of little consequence if you install and configure your server properly and use the right plugins for apps.
Our servers block an attacker who gets a password wrong for the 3rd time for 20 minutes. So you effectively only get to try every 6-7 minutes.
If you have a complex password with enough digits, you will never as able to crack it with brute force if slowed down in this manner.
Added to it that if you get blocked 20 times in a week, it becomes permanent. So 60 tries
Now it does work by IP, and even if you use multiple IPs, they just all get blocked.
This is standard functionality for CSF, a free firewall, deploying anything less would be silly!

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.

These attacks are done by ‘brute force’ meaning they use excessive forceful attempts to try and ‘force’ their way into your private account(s).
