<p>This plugin enforces a <a href="https://web.dev/articles/strict-csp" rel="nofollow ugc">Strict Content Security Policy</a> (CSP) on the frontend and login screen. This helps mitigate <a href="https://developer.mozilla.org/en-US/docs/Web/Security/Attacks/XSS" rel="nofollow ugc">cross-site scripting</a> (XSS) vulnerabilities. The policy cannot yet be applied to the WP Admin (see <a href="https://core.trac.wordpress.org/ticket/59446" rel="nofollow ugc">#59446</a>).</p>
<p>In <a href="https://core.trac.wordpress.org/ticket/58664" rel="nofollow ugc">#58664</a>, the manual construction of script tags was eliminated from <code>WP_Scripts</code> and inline scripts on frontend/login screen, thanks to the helper functions which had previously been introduced in <a href="https://core.trac.wordpress.org/ticket/39941" rel="nofollow ugc">#39941</a>.  This made it possible to apply Strict CSP, as long as themes and plugins are not directly printing <code><script></code> tags. Some bundled WordPress core themes <a href="https://github.com/search?q=repo%3AWordPress%2Fwordpress-develop+path%3A%2F%5Esrc%5C%2Fwp-content%5C%2Fthemes%5C%2F%2F+%2F%3Cscript%5B%5E%3E%5D*%3E%2F&type=code" rel="nofollow ugc">still do this</a> incorrectly (which has been reported in Trac as <a href="https://core.trac.wordpress.org/ticket/63806" rel="nofollow ugc">#63806</a>). For example, do not do this:</p>
<pre>function my_theme_supports_js() {
    echo '<script>document.body.classList.remove("no-js");</script>'; // ❌
}
add_action( 'wp_footer', 'my_theme_supports_js' );</pre>
<p>Instead, do this:</p>
<pre>function my_theme_supports_js() {
    wp_print_inline_script_tag( 'document.body.classList.remove("no-js");' ); // ✅
}
add_action( 'wp_footer', 'my_theme_supports_js' );</pre>
<p>So in order for scripts to execute, they must be printed using the relevant APIs in WordPress for adding scripts, including <a href="https://developer.wordpress.org/reference/functions/wp_enqueue_script/" rel="nofollow ugc"><code>wp_enqueue_script()</code></a>, <a href="https://developer.wordpress.org/reference/functions/wp_add_inline_script/" rel="nofollow ugc"><code>wp_add_inline_script()</code></a>, <a href="https://developer.wordpress.org/reference/functions/wp_localize_script/" rel="nofollow ugc"><code>wp_localize_script()</code></a>, <a href="https://developer.wordpress.org/reference/functions/wp_print_script_tag/" rel="nofollow ugc"><code>wp_print_script_tag()</code></a>, <a href="https://developer.wordpress.org/reference/functions/wp_print_inline_script_tag/" rel="nofollow ugc"><code>wp_print_inline_script_tag()</code></a>, and <a href="https://developer.wordpress.org/reference/functions/wp_enqueue_script_module/" rel="nofollow ugc"><code>wp_enqueue_script_module()</code></a>. Otherwise, a script’s execution will be blocked and an error will appear in the console, for example:</p>
<blockquote>
<p>Refused to execute inline script because it violates the following Content Security Policy directive: “script-src ‘nonce-9b539cfe47’ ‘unsafe-inline’ ‘strict-dynamic’ https: http:”. Note that ‘unsafe-inline’ is ignored if either a hash or nonce value is present in the source list.</p>
</blockquote>
<p>This also blocks scripts inside of <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Attributes#event_handler_attributes" rel="nofollow ugc">event handler attributes</a>, such as <code>onclick</code>, <code>onchange</code>, <code>onsubmit</code>, and <code>onload</code>. As noted on MDN:</p>
<blockquote>
<p>Warning: The use of event handler content attributes is discouraged. The mix of HTML and JavaScript often produces unmaintainable code, and the execution of event handler attributes may also be blocked by content security policies.</p>
</blockquote>
<p>This plugin also ensures that scripts added to the page from embeds (e.g. Tweets) also get the <code>nonce</code> attribute added.</p>

<h3>SITE PROTECTION FEATURES</h3>
<p>Safeguard your WordPress application using our powerful site security toolset. Our comprehensive features are specifically designed to strengthen your website’s defenses against malware, exploits, and various malicious activities. With these tools at your disposal, you can ensure the utmost bot, malware and brute force protection for your website:</p>
<h4>Lock and Protect System Folders</h4>
<p>Ensure the maximum security for your application’s system folders by preventing the execution of any unauthorized or malicious scripts. The Lock and Protect System Folders feature acts as a powerful shield against potential threats.</p>
<h4>Hide WordPress Version</h4>
<p>Protect your website from mass attacks by hiding the WordPress version, which helps to mitigate version-specific vulnerabilities.</p>
<h4>Disable Themes & Plugins Editor</h4>
<p>Enhance the security of your WordPress admin area by disabling the Themes & Plugins Editor, preventing potential coding errors and unauthorized access through the editor.</p>
<h4>Disable XML-RPC</h4>
<p>Mitigate potential security risks by disabling the XML-RPC protocol, which has been exploited in various attacks. Please note that disabling XML-RPC will restrict WordPress from communicating with third-party systems. We recommend enabling this feature unless you have a specific need for it.</p>
<h4>Disable RSS and ATOM Feeds</h4>
<p>Prevent content scraping and specific attacks on your site by disabling RSS and ATOM feeds. Unless you have readers accessing your site via RSS readers, it is recommended to keep this feature enabled.</p>
<h4>Advanced XSS Protection</h4>
<p>Add an extra layer of website security against cross-site scripting (XSS) attacks by enabling Advanced XSS Protection, bolstering the overall security of your website.</p>
<h4>Delete Default Readme.html</h4>
<p>Eliminate potential vulnerabilities by deleting the default readme.txt file, which contains information about your website. By removing this file, you reduce the risk of your site being listed in vulnerable sites targeted by hackers.</p>
<h3>Login Security</h3>
<h4>Custom Login Url</h4>
<p>Personalize your login URL to thwart potential attacks and create a strong entry point. Bid farewell to the default login URL and embrace a bespoke path of your choosing. Additionally, you have the freedom to modify the default sign-up URL as well.</p>

<h4>Disable Common Usernames</h4>
<p>Don’t fall victim to predictable security breaches! The use of common usernames, such as ‘admin,’ poses a significant threat to the integrity of your website. Activate this option to disable the creation of common usernames. If any weak usernames already exist, we’ll prompt you to provide new, stronger alternatives.</p>
<h4>Limit Login Attempts</h4>
<p>Maintain control over unauthorized access attempts with Limit Login Attempts. Set a specific threshold for the number of login failures users can endure before consequences arise. After reaching the limit, the IP address associated with the unsuccessful login attempts will be blocked for one hour. Persistent failures will result in longer restrictions, starting with 24 hours and escalating to a week.</p>
<h3>ACTIVITY MONITORING</h3>
<p>Monitor your website and login page for unauthorized visitors and brute force attempts to prevent malicious actions</p>
<h4>Activity Log</h4>
<p>The Activity Log page provides you with a comprehensive view of the activities performed by registered, unknown, and blocked visitors.

<p>To prevent any further unauthorized activities by users or attackers, you can choose to log out all users instantly using the Log Out All Users feature.</p>
<h4>Force Password Reset</h4>
<p>By enforcing a password reset, you can ensure that all users are prompted to change their passwords during their next login. This not only strengthens the security of their accounts but also immediately logs out all currently logged-in users.</p>
<h3>Requirements</h3>
<ul>
<li>WordPress 4.7</li>
<li>PHP 7.0</li>
<li>Working .htaccess file</li>
</ul>
<h3>Data Collection</h3>
<p>Collection of technical data is optional and is <a href="https://www.siteground.com/kb/what-information-wp-plugins-collect" rel="nofollow ugc">listed here</a>. This data is collected only for technical analysis, improvements and the possibility to contact the plugin user in case urgent issues need to be fixed (for example a critical security release that needs to be communicated to site owners). The plugin user can manage their preferences within the WP admin to control the collection of technical data. We advise opting in for this data collection, as it can enhance the plugin’s performance.

Security Optimizer – The All-In-One Protection Plugin

Yesterday I started researching a new security plugin that I could switch to for all my WordPress sites (about 50). Skimming the plugin directory I found SiteGround Security and I must say this is the most promising looking plugin I have ever encountered!

The biggest PRO for me: SiteGround is a professional hosting service and they are using this plugin on all WordPress sites they host, so they will have a strong motivation to keep sg-security as high-quality as possible, without the need to upsell it like so many other plugins are doing it.

I have two questions: 

1. Is there a place where you host the plugin's source publicly, like for example on GitHub? I couldn't find anything except a security warning about 2FA in an earlier version (1.2.5, can't post link here due to WP guidelines).

2. What was your reasoning behind not making the limit_login_attempts periods (1 hour, 1 day, 1 week) un-filterable? I wanted to immediately reduce the first period to something like 20 minutes, but those periods are hard-coded right now inside SG_Security\Login_Service\Login_Service->log_login_attempt( $error ) (Version 1.3.7).

Thanks again.

Wow!


Llevo decenas de webs de clientes y he encontrado muchas webs infectadas con plugins de seguridad premium. 



Tras instalar el plugin de seguridad de SiteGround y un buen cortafuegos nunca más he tenido problemas en ninguna web.


Sencillo y efectivo, mejor que el resto


Cannot unsubscribe from the emails without admin access. In my experience, this makes the plugin extremely annoying. They do not plan to fix this.
