WordPress is the most popular blogging platform. It is because of its robust nature and its user-friendliness. More than 37% of the internet is using WordPress as their blogging platform. Not to forget, many popular websites are also using WordPress.
As it is growing fast it is also becoming center of the eye for hackers. Hackers are also interested in hacking WordPress based websites.
WordPress usually pushes updates to patch all the known vulnerabilities. Sometimes hackers also find those vulnerabilities in WordPress which helps them to hack the whole server. A lot of websites have been hacked in the past.
WordPress does have some pretty solid security measures. But, if you want to take that security to the next level you need to install a suitable WordPress security plugin. It protects your site from brute force attacks and regulates regular security scanning, monitoring, notifications and malware attacks.
