Note: Two-factor authentication is very effective against many types of attacks, including keylogger attacks. Very persistent attackers might try to overcome that obstacle, but most will turn around and search for an easier target. Even if an attacker cracks the password, they would have to have access to your smartphone or email client.

The great thing about 2FA is that password alone is not enough. Implementing such a solution greatly reduces the risk of a potential data breach. Two-factor authentication is considered by many to be the first line of defense against brute force attacks. One downside is that this might not be appropriate for every use case. If you don’t have a static IP address, you can configure a VPN instead. You can set this up by scoping a remote access port to a static IP address. It is like placing a security perimeter around your most precious data, and everyone who doesn’t originate from the right IP address is not allowed access. 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. Limit Logins to a Specified IP Address or Range That single requirement to enter a word, or the number of cats on a generated image, is highly effective against bots, even though hackers have started using optical character recognition tools to get past this safety mechanism.īear in mind that the use of tools such as CAPTCHA negatively impacts the user experience. Nobody likes trying to make sense of something that looks like it’s been scribbled by a two-year-old, but tools such as CAPTCHA render automated bots ineffective. We all got used to seeing CAPTCHA on the internet. To switch to a non-standard port, edit the port line in your sshd_config file. So, running sshd on a different port could prove to be a useful way of dealing with brute force attacks. Most automated SSH attacks are attempted on the default port 22. Set the ‘DenyUsers root’ and ‘PermitRootLogin no’ options. Make sure to make the root user inaccessible via SSH by editing the sshd_config file.

SSH brute force attempts are often carried out on the root user of a server.

Additionally, admins will not have to deal with unlocking several hundred accounts every 10 minutes or so. This means that automated brute force attack tools will not be as useful. However, if performed with progressive delays, this method becomes much more effective.Īccount lockouts with progressive delays lock an account only for a set amount of time after a designated number of unsuccessful login attempts. Account Lockouts After Failed AttemptsĪs 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. Be proactive to detect and stop DDoS attacks.ġ. Your server would be easy prey for denial-of-service. 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.įor example, if a server were under attack frequently, several hundred user accounts could be locked-out constantly. Hackers can launch wide-scale attacks by trying a single password on several thousand servers. Unfortunately, that alone is not always sufficient. Locking out accounts after a certain number of incorrect password attempts is a common practice of dealing with brute force attempts.

The attack will leave a series of unsuccessful login attempts, as seen below: Sep 21 20:10:10 host proftpd: yourserver (usersip) - USER theusername (Login failed): Incorrect password. You can detect them by looking into your Apache access log or Linux log files.

How to Identify Brute Force AttacksĪ brute force attack is easy to identify and investigate.

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.Ĭreating code that executes this type of attack doesn’t take much imagination or knowledge, and there are even widely available automated tools that submit several thousand password attempts per second. The attacker aims to forcefully gain access to a user account by attempting to guess the username/email and password. 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. As the name implies, brute force attacks are far from subtle. A brute force attack is among the simplest and least sophisticated hacking methods.
