When WordPress security is in question, there are several issues that can accrue. This is the reason why most WordPress site owners are in a constant move to invest in WAFs as a way of protecting their websites from malicious actors and bots. The WAF is simply a program that filters and monitors the application traffic and the website traffic and identify and prevent any malicious activities from permeating the website or attacking it.
