WP Author Security is a lightweight but powerful plugin to protect against user enumeration attacks on author pages and other places where valid user names can be obtained.
By default, WordPress will display some sensitive information on author pages. 
The author page is typically called by requesting the URI <code>https://yourdomain.tld/?author=<id></code> or with permalinks <code>https://yourdomain.tld/author/<username></code>. 
The page will include (depending on your theme) the full name (first and last name) as well as the username of the author which is used to log in to WordPress.
In some cases, it is not wanted to expose this information to the public. An attacker is able to brute force valid IDs or valid usernames. This information might be used for further attacks like social engineering attacks or log in brute force attacks with gathered usernames. 
However, when using the plugin and you disable author pages completely it must be noted that you need to take care that your active theme will not display the author name itself on posts like “Posted by admin” or something like that. This is something the plugin will not handle (at the moment).
By using the extension, you are able to disable the author pages either completely or display them only when the author has at least one published post. When the page is disabled the default 404 error page of the active theme is displayed.
In addition, the plugin will also protect other locations which are commonly used by attackers to gather valid user names. These are:
<ul>
<li>The REST API for users which will list all users with published posts by default. 
 https://yourdomain.tld/wp-json/wp/v2/users</li>
<li>The log in page where different error messages will indicate whether an entered user name or mail address exists or not. The plugin will display a neutral error message independently whether the user exists or not.</li>
<li>The password forgotten function will also allow an attacker to check for the existence of a user. As for the log in page the plugin will display a neutral message even when the user does not exists.</li>
<li>Requesting the feed endpoint /feed of your blog will also allow others to see the username or display name of the author. The plugin will remove the name from the result list.</li>
<li>WordPress supports so-called oEmbeds. This is a technique to embed a reference to a post into another post. However, this reference will also contain the author name and a direct link to the profile page. The plugin will also remove the name and link here.</li>
<li>Since WordPress 5.5 a default sitemap can be reached via /wp-sitemap.xml. This sitemap will disclose the usernames of all authors. If this should not be disclosed you are able to disable this feature of WordPress.</li>
</ul>

<h3>Security Fixers</h3>
Admin & API Security
<ol>
<li>Stop User Enumeration Hackers & bad bots can easily find usernames in WordPress by visiting URLs like yourwebsite.com/?author=1. This can significantly help them in performing larger attacks like Bruteforce & SQL injection.</li>
<li>Change Login URL Prevent admin password brute-forcing by changing the URL for the wp-admin login area. You can change the url only when this fixer is disabled.</li>
<li>Disable XMLRPC XMLRPC is often targeted by bots to perform brute force & DDoS attacks (via pingback) causing considerable stress on your server. However, there are some services which rely on xmlrpc. Be sure you definitely do not need xmlrpc before disabling it.</li>
<li>Disable WP API JSON Since 4.4 version, WordPress added JSON REST API which largely benefits developers. However, it’s often targeted for bruteforce attacks just like in the case of xmlrpc. If you are not using it, best is to disable it.</li>
<li>Disable File Editor If a hacker is able to get access to your WordPress admin, with the file editor enabled it becomes quite easy for them to add malicious code to your theme or plugins. If you are not using this, it’s best to keep the file editor disabled.</li>
<li>Disable WordPress Application Passwords WordPress application passwords have full permissions of the user that generated them, making it possible for an attacker to gain control of a website by tricking the site administrator into granting permission to their malicious application.</li>
</ol>
Disable Information Disclosure & Remove Meta information
<ol>
<li>Hide WordPress version number 
 This gives away your WordPress version number making life of a hacker simple as they’ll be able to find targeted exploits for your WordPress version. It’s best to keep this hidden, enabling the button shall do that.

Security Headers
<ol>

Protect your WordPress Website from clickjacking with the X-Frame-Options response header. Clickjacking is an attack that tricks a user into clicking a webpage element which is invisible or disguised as another element.</li>
<li>XSS Protection 
Add the HTTP X-XSS-Protection response header so that browsers such as Chrome, Safari, Microsoft Edge stops pages from loading when they detect reflected cross-site scripting (XSS) attacks.</li>
<li>Content Sniffing protection 
Add the X-Content-Type-Options response header to protect against MIME sniffing vulnerabilities. Such vulnerabilities can occur when a website allows users to upload content to a website, however the user disguises a particular file type as something else. This can give them the opportunity to perform cross-site scripting and compromise the website.
</li>
<li>HTTP only & Secure flag 
Enable the HttpOnly and secure flags to make the cookies more secure. This instructs the browser to trust the cookie only by the server, which adds a layer of protection against XSS attacks.</li>
