Sucuri – The Plugin With Security Proved Features

Sucuri specializes in WordPress security and comes with a range of security features for your website that offers a positive influence on the security posture of your website. Some of these include:

Security Activity Auditing

This is probably the most underused security function. It involves the act of monitoring all security-based events inside your WordPress install. The issue is, what constitutes a security event. According to Sucuri, any modifications that happen within the application could be classified as a security event, and so we attempt to record it.

This is vital since it offers you, the website owner, the capacity to maintain a good eye on the different changes taking place within your environment. Who is logging in? What alterations are being made?

This feature involves logging the entire activity to the Sucuri cloud, for keeping it safe. This assures that an attacker is not able to obliterate your forensic data and stop further security analysis following a compromise. If an attacker succeeds in bypassing your security controls, your security logs will be safely maintained within the Sucuri Security Operations Center (SOC).

This feature is especially important to website/system administrators and security experts looking to know what is happening with their website and when it’s occurring.

WordPress Hardening

Security hardening options comprise preventative measures to raise security in regions of your website that could turn into avenues for attack. This is performed by inserting a set of rules in your .htaccess file and checking secure configurations.

Sucuri aids you take measures to strengthen your website from external threats. You can enable every feature with the click of a button.

Enable Hardening Options

To enable and disable security hardening in the WordPress security plugin:

Log in to the WordPress dashboard.

From the right-side menu below the Sucuri Plugin, go to Settings.

Go to the top menu and choose Hardening

Click the Apply Hardening button to any of the security options enumerated below,

Sucuri Plugin Settings And Hardening Options

Hardening options:

  • Website Firewall Protection – If you are a Sucuri customer, you can join to your firewall account to see statistics in WordPress.
  • Verify WordPress Version – Checks when your website or any of its elements are not up to date, this section will alert you with a prompt to the latest version.
  • Verify PHP Version – Examines if your server is running the newest version of PHP.
  • Remove WordPress Version – Permits you to remove the version of your CMS from being publicly displayed.
  • Block PHP Files In Upload Directory – Disables the implementation of PHP files within your uploads directory. This can break specific plugins so test beforehand.
  • Block PHP Files in WP-CONTENT Directory – Positions a .htaccess file within the wp-content to stop external access.
  • Block PHP Files In WP-INCLUDES Directory – Similar to above but for wp-includes.
  • Information Leakage – Examines the presence of a readme-html file on your site, which includes your WordPress version and deletes it.
  • Default Admin Account – Checks for the admin user. This used to be normal in earlier times and is a preferred target for hackers.
  • Plugin And Theme Editor – Disables the plugin and theme editor to stop access to sensitive files by other users (and probable hackers who have broken into your site).

You will also discover the option to Whitelist PHP Files that have been blocked by scrolling down the page. After you add the hardening in either the content, includes, and/or upload directories, the plugin will insert a rule in the access control file to refuse access to any PHP file located in these folders.

This is a nice precaution if an attacker has succeeded in uploading a PHP script. With some exceptions, the “index.php” is the sole one that should be publicly accessible. Nevertheless, many theme/plugin developers plan to use these folders to process some operations. In such a case, employing the hardening may break functionality, so whitelisting can be utilized to permit only these files.

Malware Scanning

Among the most famous tools integrated into the Sucuri WordPress security plugin is the malware scanner.

This free tool, powered by Sucuri SiteCheck, scans your website for:

  • Malware
  • Website Errors
  • Blacklist Status
  • Security Anomalies

Contact our team for a complete server-side scan.

Core Integrity Check

The Sucuri WordPress plugin includes tools that examine the integrity of the core WordPress files – PHP, CSS, JavaScript – and different files that accompany your original WordPress version.

Hackers alter core files to insert backdoors, which are pieces of code that lets them circumvent the security measures. Eliminating all backdoors from an infected site is critical to prevent reinfection.

Website Security Plugin Versus Website Firewall

No website security plugin is able to cope with distributed denial of service (DDoS) attacks. A DDoS attack is not just an application-type-of-attack, it can also attack the very network which happens before a plugin is implemented. Even a plain SYN (synchronize) attack is sufficient to bring down a website, though it may have security plugins installed.

The premium version of the Sucuri plugin is really not a plugin, though the Sucuri website firewall that stops malicious traffic prior to its reaching your website – including DDoS attacks. The Sucuri website firewall wards off nearly 40 million attacks each day. It also contains a free CDN and DNS. These features accelerate the website, whereas a few other security plugins retard the website as they are based upon server resources.

The Sucuri firewall aids your website get PCI compliant and updates every day through their team of skilled researchers and engineers.

Does The Plugin Conflict With WordFence?

The plugin doesn’t, but there may be problems with our scanners. If you receive an “Unable to Properly Scan Your Site” error, it’s probably due to the WordFence plugin blocking our scanner like an invalid crawler. You would be required to white list our IP address on the WordFence dashboard.

Website Security Monitoring
