On Apache servers, you can add IP addresses to your. AdminExcile, however, can prevent your site from going down by blocking the IPs after X failed attempts. The main reason the attack didn’t succeed was strong passwords. That’s when I adjusted the AdminExcile plugin to block the perpetrators after fewer attempts and for a longer period of time. Another day, I had 25000 brute-force attempts on another website. It didn’t succeed, and we managed to block the IPs permanently rather quickly. I recently had an attack on a website where over 4000 machines tried to brute-force their way into a Joomla site. This has proven very effective for me, as I’ve avoided some very nasty attacks.

It lets you block IPs after a certain amount of failed password attempts, and you can set how long the block will be in effect for. I recommend AdminExcile as an excellent plugin for Joomla 2.5 or later. Blocking access to the siteĪnother method of avoiding the perils of brute-force attacks is to restrict access to the website or server based on the attackers IP or IP range. Just make sure you have a solid master password, and you might consider investing in a Yubikey for a two-factor authentication with Joomla. Using these tools, there is no problem managing hundreds, or thousands of passwords with ease.

I’ve heard lots of good things about 1Password as well, so if you’re on a Mac you might wanna try that out. Personally, I use to both generate and manage my passwords. Three words: Password Management Software. And I never use a password for more than one website.Ģ0 characters, you say? How on earth do you remember that? When it comes to passwords, I always use 20 random alphanumeric characters or more, in a combination of lower and upper case, and with some symbols thrown in. I choose a unique username for each site. I have made it a habit to never use ’admin’ or ’administrator’ or anything like it as usernames on my websites.

You’ve heard it time and time again: Make sure you have strong passwords! Usernames are important, too. Longer and more complex usernames passwords is one, blocking access to the site is another. There are several things you can do to make things harder for those trying brute-force attacks.

How to protect yourself from brute-force attacks The other thing to be concerned a about is the fact that such attacks take away a lot of capacity from your server. Obviously, it’s not good having people snoop around in your Joomla admin with super administrator rights. There are two main problems with this for you as a website owner. In short, a brute-force attack is trying to force itself into your website administrator by trying every combination of username and password it can come up with. When password guessing, this method is very fast when used to check all short passwords, but for longer passwords other methods such as the dictionary attack are used because of the time a brute-force search takes. In the worst case, this would involve traversing the entire search space. It consists of systematically checking all possible keys or passwords until the correct one is found. Such an attack might be used when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the task easier.

In cryptography, a brute-force attack, or exhaustive key search, is a cryptanalytic attack that can, in theory, be used against any encrypted data (except for data encrypted in an information-theoretically secure manner).
