Features of Imunify360 for WordPress

Brute Force Protection

Brute force attacks are a common threat, attempting to gain unauthorized access by systematically trying numerous username and password combinations. Imunify360 works in conjunction with your server’s Web Application Firewall (WAF) and Mod Security to offer formidable brute force protection.

It deploys an enhanced set of security rules that extend beyond basic protection, covering everything from SQL injection attempts to file inclusions and, crucially, brute force attacks. When an attacker's IP address triggers one of these rules due to suspicious activity, Imunify360 intelligently blocks that IP, effectively preventing further malicious requests and safeguarding your site from unauthorized access.

Malware Protection

Ensuring a site is adequately protected against malicious scripts can be a time-consuming and challenging endeavor. However, with Imunify360, the process of malware scanning, detection, and remediation becomes remarkably streamlined. The intuitive dashboard allows for efficient management of your site's security.

Users can initiate a comprehensive malware scan across all websites hosted on the web server with a single click using the "scan all" button, typically located in the upper right section of the interface. Alternatively, for more targeted inspections, individual site scans can be triggered by selecting the "play button" icon adjacent to the desired website entry. This flexibility ensures that you have full control over your scanning processes, whether you're performing a server-wide check or focusing on a specific domain.

Beyond simply identifying threats, Imunify360 empowers you to address them directly from the dashboard. Any flagged malicious files can be swiftly cleaned up using the green "clean up all" button, often represented by a "broom" icon. This remediation option is prominently displayed within the "Malicious" section of the Imunify360 Malware tab, where it lists all detected compromised files.

While the example above might not show any files, demonstrating the absence of current threats, it's important to note that if malicious files were present, a distinct green "clean up all" button would appear in the upper right area, above the "actions" column. Selecting this button initiates a thorough cleansing process, removing all flagged items and restoring the integrity of your website. This seamless integration of scanning and cleaning capabilities significantly reduces the effort required to maintain a secure online environment.

Harden PHP with Imunify360

A fundamental aspect of proactive malware prevention involves hardening the PHP environment on your server. This critical step greatly contributes to preventing code exploits from compromising your website. Imunify360 simplifies this process, making it accessible and efficient.

To enable the PHP hardening feature within Imunify360, an installation command needs to be executed via the command-line interface (CLI) within the web server environment. This command activates the necessary components for enhanced protection:

Once installed, you can verify its active status by logging into your WebHost Manager (WHM) panel and navigating to the "Proactive Defense" menu within the Imunify360 interface. Here, you'll confirm that "Kill Mode" is enabled. Kill Mode is a powerful feature that automatically terminates or "kills" any malicious scripts as soon as they are detected by Imunify360, preventing them from executing further harm.

Additionally, the active status of PHP hardening by Imunify360 can be confirmed through the command-line interface using another specific command. This provides a direct, technical verification of the feature's operational state.

As illustrated in the example above, an "enabled" or "True" status confirms that PHP hardening is active and effectively managed by the Cloud Linux environment, ensuring continuous protection against potential code-based exploits.

Monitor Incidents

The "Incident" tab within Imunify360 serves as a comprehensive log of all monitored security activities on your server. This invaluable section meticulously records and reports any potentially malicious behavior that has occurred, providing administrators with critical insights into attempted attacks and vulnerabilities.

The tracked activities span a wide range, from suspicious login attempts to requests for potentially malicious files. Crucially, any such attempts deemed hostile are promptly blocked by the Web Application Firewall, preventing them from impacting your site. When an event within the Incidents tab is selected, it expands to reveal detailed information, offering a granular view of the incident.

This expanded view typically showcases vital details such as confirmation that Mod Security (the WAF) blocked the attempt, the specific rule number that was triggered, the IP address involved in the malicious activity, and a concise description of the action that was prevented. This level of detail is instrumental for understanding attack vectors, identifying persistent threats, and refining security policies.

By providing such transparent and comprehensive incident reporting, Imunify360 empowers website administrators to stay fully informed about their server's security status, enabling quick responses and proactive measures to maintain a secure online environment.

Domain Reputation

Maintaining a positive domain reputation is absolutely critical for several aspects of your online presence, particularly email deliverability and search engine visibility. A poor domain reputation can lead to emails being marked as spam and significantly affect how your site ranks in search engine results. Recognizing this, Imunify360 includes robust features to monitor and protect your domain's standing.

With Imunify360, you receive timely alerts regarding any issues that might compromise your domain's reputation. This early detection capability is invaluable, allowing you to take immediate corrective actions before minor problems escalate into major disruptions. The "Reputation Management" option, easily accessible via the "3 dots" menu in the upper right of the Imunify360 dashboard, provides access to this crucial monitoring.

Within this section, Imunify360 displays comprehensive information if a domain is detected on any blacklists. This includes the domain name in question, the specific type of threat identified, the vendor or service responsible for the listing, the date of detection, and a description of the action or event that led to the listing. This detailed reporting empowers you to understand the root cause of reputation issues and implement targeted solutions to restore and maintain a healthy domain reputation.

Firewall Monitoring

Staying informed about the activities of your server's firewall is a vital component of a proactive security strategy. Imunify360 simplifies this by providing a dedicated firewall monitoring interface, offering a clear overview of all recent firewall activity. This feature is essential for maintaining control and understanding the security events unfolding on your server.

The firewall monitoring section displays important information, including records of IP blocks that have been enacted due to suspicious activity, as well as any IP addresses that have been whitelisted for legitimate access. This transparency allows administrators to quickly identify potential threats, review blocked attempts, and ensure that only authorized traffic reaches their websites. Regular review of this activity helps in fine-tuning security rules and maintaining an optimal defense against evolving cyber threats.

Bot Protection

Malicious bots pose a significant threat to websites, contributing to spam, resource exhaustion, and unauthorized access attempts. Imunify360 provides a sophisticated bot protection mechanism designed to effectively counter these "bad actors." When a malicious bot is detected attempting to access your site, Imunify360 intelligently redirects it to a challenge page.

This challenge page acts as a barrier, requiring the bot to solve a task before it can proceed to view your web content. This process is seamless for legitimate human users, who experience no disruption and can access your site as usual. However, for bots, it serves as a powerful deterrent, significantly reducing spam activity on contact forms, mitigating the impact of login attempt floods, and preserving server resources that would otherwise be consumed by illegitimate traffic.

The effectiveness of this feature lies in Imunify360's ability to accurately differentiate between legitimate visitors and potential bad actors, presenting challenges only when necessary. This proactive defense is particularly beneficial for servers that frequently experience overwhelming traffic from bots, helping to alleviate the burden on server resources. Moreover, this same bot protection functionality extends to cPanel user accounts, ensuring that attempts by bots or unauthorized entities to access cPanel are also met with a challenge page, adding another layer of security to your hosting environment.
