Today we finished the year 2008, and I want to fire him with a security tip for our blogs, and that is one of the most common ways by which someone can try to enter your WordPress blog is through attacks of brute force one of the best-known modes of cracking passwords . What the attacker will try to do is use any possible combination of characters to guess your password, usually by means of some software specialized in this type of tasks.
This is a good time to remind you that you always use passwords with a mixture of uppercase, lowercase, numbers and special characters, which will make difficult the task of the attacker to a great extent to increase the combinations necessary to crack it.
Fortunately, there is a plugin that can protect your blog from this type of attacks. Login LockDown saves the IP addresses and timestamps of each failed connection attempt. If more than a certain number of attempts are detected in a short period of time from the same IP range, then the plugin deactivates the connection function to your blog from that range. By default, the plugin has set an IP blocking time after 3 unsuccessful attempts for a period of 5 minutes, however you can modify it in the plugin options panel. In addition, you can also directly block IP ranges from that same panel of options.
