    Brute force (also known as brute force cracking) 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.

    Its like simply large number of login attempts caused by a software trying to break your site access and it will cause heavy load on the server due to numerous requests and it will cause your server to go down

    Brute force attack is used for guessing the private and important information such as password, login details, account number, credit card number. They use the automated software to guess the password. There are several guesses generated from which correct password can be obtain. This is trial and error method to encrypt the data.

    Below are some of the prevention techniques -

    1. Do not disclose the root password.
    2. Never exchange the password using mails.
    3. Use the strong password for your all accounts like email address, your administrative panel etc.
    4. If you will give the SSH access to your users then make sure you will not provide the all privileges. You should grant the limited access.
    5. Set fail2ban on server so it will help you to prevent the access to un-legitimate IP address.
    6. Keep all applications up to date.
    7. Always patch the scripts.
    8. Set correct permission for files and directories.

    A Brute Force Attack is the simplest method to gain access to a site or server (or anything that is password protected). It tries various combinations of usernames and passwords again and again until it gets in. This repetitive action is like an army attacking a fort.

    Yes, you can take some precautionary measures:

    Create a longer password. Longer passwords are harder to break.
    Your password should have both UPPERCASE and lowercase alphabets, numbers, and special characters. This way, you’ll be able to delay the process of cracking.

    I think Brute Force Attacks are todays norm. I see a lot against Return OWA, and other community experiencing websites that need to be there. I neglect most of these, as I cannot management or quit them.

    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.

    A savage power assault is an experimentation technique used to acquire data, for example, a client secret key or individual recognizable proof number (PIN). In a savage power assault, computerized programming is utilized to create an extensive number of back to back estimates with regards to the estimation of the coveted information.

    Basically, a Brute Force Attack is whenever you get bombarded with traffic or login attempts to try and take down your server. You can prevent them by having a host with DDOS protection and by blocking countries where DDOS attacks often come from.

    Brute force attack means by its name we get to know its an attack to your server or website. This attack is done automatically by attacking software. In today's internet world there any many brute force software's are available (also works like bots in internet) in internet which are ready to attack your servers or website if its not secured well.

    The work of brute force software is to attack your server with high number of login attempts with all possible methods and this way brute force attack software keeps your server or website network busy and at this time your server or website will not work as it will not listen to the request from outside world when it get busy in answering to brute force attack software.

    Hope this make you everything clear about brute force attack.
