Most WordPress security plugins tend to have similar functionalities to prevent cybercriminals from attacking and stealing information. Some of the main operations done by security plugins are Malware Scanning, Brute-Force Login Protection, Web Application Firewall, and Rate-Based Throttling and Blocking.

Malware Scanning 

Some plugins clean up the aftermath of infiltration, and they check for malware injection. Scans are conducted to identify any website changes, and the source code is verified with its original. These scans are constantly updated in the background, and if they find anything suspicious, they leave a comment or advice to take necessary action to repair or fix the problem.

Brute-Force Login Protection 

This method is used to block out hackers that are trying to infiltrate the WordPress website. If a user fails to log in after entering multiple wrong passwords, the system recognizes this as a forced entry and immediately blocks that user. Such cybercriminals deploy an automated script to try thousands of passwords. A feature like brute-force login protection allows website owners to lock out anyone entering an invalid username.

Web-Application Firewall 

We know that firewalls are the last line of defence, and when it comes to website security, you have to be careful about the vulnerabilities you are exposing to the outside world. These loopholes may not be publicly known, but they sure make it to some other security communities. Having a robust web application firewall deployed by some WordPress security plugins can recognize any user exploiting the loopholes and stop them instantaneously.

Rate-Based Throttling and Blocking 

This is another important operation deployed by WordPress plugins. It is crucial to have one of these features because hackers overload your website with traffic from one IP. And it can lead to users not being able to access your content through the search engine. WordPress security provides plugins with rate-based throttling and blocking features to limit user requests from one geographical location to resolve this issue.

Though there are many more functionalities associated with WordPress security plugins, these are essential to keep in mind. Now that you know how plugins operate, the next thing to deal with is plugin categories.
