Not so easy to count, is it? Make sure your password is strong and unique!

In this article, we dive into brute force attacks — what they are, how hackers are using them, and prevention techniques. A brute force attack is among the simplest and least sophisticated hacking methods.

As the name implies, brute force attacks are far from subtle. The theory behind such an attack is that if you take an infinite number of attempts to guess a password, you are bound to be right eventually. Usually, the motive behind it is to use the breached account to execute a large-scale attack, steal sensitive data, shut down the system, or a combination of the three. The attack will leave a series of unsuccessful login attempts, as seen below:.

Does Locking-Out Accounts Work? Locking out accounts after a certain number of incorrect password attempts is a common practice of dealing with brute force attempts. Unfortunately, that alone is not always sufficient. Hackers can launch wide-scale attacks by trying a single password on several thousand servers. As opposed to attempting many passwords on a single server, this method does not trigger the account lockout, and it cleverly bypasses this defensive mechanism.

For example, if a server were under attack frequently, several hundred user accounts could be locked-out constantly. Your server would be easy prey for denial-of-service.

Be proactive to detect and stop DDoS attacks. However, hackers have caught on and started using dictionaries that substitute letters with common Leet characters. The same goes for other common encrypting methods, such as SHA The most obvious is a strong password policy. Each web application or public server should enforce the use of strong passwords. For example, standard user accounts should have at least eight letters, a number, uppercase and lowercase letters, and a special character.

Moreover, servers should require frequent password changes. As stated above, implementing an account lockout after several unsuccessful login attempts is ineffective as it makes your server easy prey for denial-of-service attacks. However, if performed with progressive delays, this method becomes much more effective. This means that automated brute force attack tools will not be as useful. Additionally, admins will not have to deal with unlocking several hundred accounts every 10 minutes or so.

SSH brute force attempts are often carried out on the root user of a server. Most automated SSH attacks are attempted on the default port So, running sshd on a different port could prove to be a useful way of dealing with brute force attacks. That single requirement to enter a word, or the number of cats on a generated image, is highly effective against botseven though hackers have started using optical character recognition tools to get past this safety mechanism.

If you allow access only from a designated IP address or range, brute force attackers will need to work hard to overcome that obstacle and forcefully gain access. You can set this up by scoping a remote access port to a static IP address. One downside is that this might not be appropriate for every use case. Two-factor authentication is considered by many to be the first line of defense against brute force attacks. Implementing such a solution greatly reduces the risk of a potential data breach.

The great thing about 2FA is that password alone is not enough. Even if an attacker cracks the password, they would have to have access to your smartphone or email client. Very persistent attackers might try to overcome that obstacle, but most will turn around and search for an easier target. Note : Two-factor authentication is very effective against many types of attacks, including keylogger attacks.Limit Login Attempts for login protection, protect site from brute force attacks.
