Brute Force Attack is the method of guessing username and passwords anything that is password protected with an automated software or program. It tries various combinations of usernames and passwords again and again.

How to prevent it:
1. Password Length : Password length should be 8-16 characters.
2. Password Complexity: Password should be combination of Alphanumeric. (Capital letters, small letters, Numbers, Special characters, Ascii characters)
3. Limit Login Attempts: In admin panel set maximum If your website receives five failed login attempts; it should block that IP for a certain period of time to stop further attempts being made.
4. Changing Password: Passwords must be changed frequently (every month).
 
Usually bruteforce attack is handled by tool like Fail2ban or CSF (ConfigServer Firewall), these configurable tools can scan your logs and when they find too many errors resulting from denied login, they can ban the bruteforcing IP. As Loonycgb2 said, it is important to know on where the bruteforce is targetted, on which service (HTTP, SSH, FTP, etc.)
 
Denial of services caused by a attacker or group of attackers. They hit your server with multiple ips jamming all the resources on your server or network. Sometimes they even use virus to brute force.
 
Brute force attack is a trial and error method wherein continuous inputs are given to a field to gain access.
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 attacks may be used by criminals to crack encrypted data, or by security analysts to test an organization's network security.

In cryptography, a brute-force attack consists of an attacker trying many passwords or passphrases with the hope of eventually guessing correctly. The attacker systematically checks all possible passwords and passphrases until the correct one is found.
 
'brute force attack' is done by trying or guessing for username and password until correct guess. In this kind of attack attacker consistently try or guess a possible username and password and after some time finally attacker got success.

You can prevent from this attack by using:
1. Using software which will deny a user after a predefined number of attempts.
2. Complexity of password.
3. Usiing captcha. etc.
 
In a brute force attack the hacker makes an attempt to try various password combinations to enter into any website repeatedly. this attack is performed by the hackers that use maliciously installed bots in other computers for improving the computing power needed.

In simple words it is a way to gain access to a site or server (or any other thing that is secured with encryption).

Hi

Brute Force Attack is the most basic method to attempt breaching a password protected server or website.

What happens in a Brute Force Attack is the attacker conducts multiple attempts of password combinations on the protected site (or server) until they get in.

Brute Force Attacks are commonly done in order to gain access to a server or site and spread malicious software through it or completely shut it down.

You can prevent this type of an attack mostly by increasing the complexity and length of your password, harden security through adding .htaccess rules. You can limit admin access to only a few IPs that are listed.

Modify your .htaccess file as so:

<Files /wp-login>

order deny,allow

allow from IP1

allow from IP2

deny from all

</Files>

Hope this helped.

i.e A software generate a number of guesses to obtain desired data

Locking Accounts. The most obvious way to block brute-force attacks is to simply lock out accounts after a defined number of incorrect password attempts. Account lockouts can last a specific duration, such as one hour, or the accounts could remain locked until manually unlocked by an administrator.

A suggestion for a fairly simple defense against people who spam attacks:

CHANGE YOUR PORT #s

While this easy step won't prevent a malicious actor specifically targeting you, just investigate yourself and set up a box with an open SSH port 22 and see how many thousands if not hundreds of thousands of requests you get. Switch that port 22 to a port #### and then the time complexity of those attackers attack goes up dramatically and you stop getting pestered and are safer against the throes of automated attacks.
 
An activity which involves repetitive successive attempts of trying various password combinations to break into any website. It is the simplest method to gain access to a site or server.
To Prevent it:

Password Length.
Password Complexity.
Limit Login Attempts.
Modifying .htaccess file.
Using Captcha.
Two Factor Authentication.
