Sucuri Security - Auditing, Malware Scanner and Security Hardening

More information on the Sucuri Security WordPress plugin can be found in our Knowledge Base. One of the standout features of our WordPress plugin is the comprehensive audit logging system. At Sucuri, we recognize that every change within your application can be a potential security event. From user logins to content modifications, our audit logs are designed to capture all security-related activities on your site. These logs provide you with crucial visibility into your website's operations, answering key questions such as:

• Who logged in? Understanding who accesses your site is fundamental to ensuring that only authorized users are logging in. This helps in identifying any unauthorized access attempts, allowing you to respond swiftly to potential security breaches.
• What changes were made? Essential for maintaining its integrity and security. By knowing what modifications have been made, you can quickly pinpoint any suspicious activities or errors that need attention. With the release of version 1.9.6, we've enhanced this feature, allowing you to filter audit logs by event types and dates. This improvement offers you even greater insight into your site's activities, enabling proactive security management.

Security File Integrity Monitoring has been fundamental to the world of security. It's the act of comparing a known good with the current state. If the current state differs from the known good, you know you have a problem. This is the basis of a lot of host intrusion detection systems. We have built that into this plugin. It will create a known good the minute the plugin is installed. This will be of all the directories at the root of the install, including plugins, themes and core files.

Once this plugin is installed and activated, we automatically scan your site searching for known malware, viruses, blacklisting status, website errors, out-of-date software, and malicious code. We access your site just like a regular visitor would as this helps us catch threats that try to stay hidden from bots or search engines. This feature is powered by our free website security scanner – SiteCheck.

Another very interesting feature of the website Security Malware Scanner is that it checks various blocklist engines, including the following:

• Sucuri Labs
• Google Safe Browsing
• Norton
• AVG
• Phish Tank
• ESET
• McAfee Site Advisor
• Yandex
• SpamHaus
• Bitdefender

Our team cleans thousands of websites every day, giving us deep insight into the most effective ways to protect WordPress sites. We've used that experience to create a list of actionable recommendations available in the Hardening & Prevention section of this plugin. To name a few (note that this will depend on your environment), these actions are:

• Enable Website Firewall Protection
• Remove WordPress Version
• Block PHP Files in Uploads, wp-content and wp-includes directories.
• Verify default admin account.
• Disable Plugin and Theme Editor.
• Automatic Secret Keys Updater.

Even with the strongest security measures, no site is 100% safe from hacking. When a compromise occurs, the Post-Hack section of our plugin guides you through four critical steps to help you regain control of your site:

• Update Secret Keys.
• Reset User Passwords.
• Reset Installed Plugins.
• Update Plugin and Themes.

Security features only matter if you know when something's wrong, that's why we included a set of customizable security alerts inside our Settings > Alerts section. You can also customize how frequently you want to be alerted of security related events.

This is by far the coolest security feature Sucuri has to offer everyday website owners. It's an enterprise grade Website Firewall designed to give you the best security protection any website can hope for. It protects your website from a variety of website attacks, including:

• WordPress core, PHP, plugins and themes vulnerability scanners.
• Firewall Management.
• Events Reporting (auditlogs).
• Headers Management.
• Hardening & Prevention.

Yes. This plugin compliments your existing security toolsets. It is not designed to replace the Sucuri Website Security or Firewall products.

No, they do not.

Not that we are aware of.

Go to the Headers Management page and enable Cache-Control header by selecting a mode according to your website's need and click on submit. You can also activate the Cache-Control header by updating the cache header fields in one of the page types by using the "Edit" button in the table rows. Please remember to enable site caching on your WAF to use these settings. If you are a Sucuri client and require assistance, please create a ticket and reach out to the firewall team for support.

To enable CORS headers please visit the Headers Management page. For the time being, we only support "Report-Only" as these headers can break your site.
