WordFence, the WordPress security plugin company, tells me that unsophisticated brute-force attacks have doubled in the past three weeks. While WordFence can help keep your WordPress instances up and running, your server is still getting mauled. What can you do about it? You can use Fail2Ban to patch your firewall against blunt attackers in real time.
It’s a shame that many of you haven’t heard of, never mind use, Fail2Ban. I’ve found it to be a very useful and easy way to protect servers that is just as easy to install and deploy.
