Imunify360 is a comprehensive security suite that protects Linux web servers from cyber threats. Developed by CloudLinux, it employs machine learning and a multi-layered approach to safeguard servers against malicious attacks and abnormal behavior, including distributed brute-force attacks
Essential Security Layers and Tools for Robust Server Protection
Utilizes cloud heuristics and artificial intelligence to detect and block new threats, defending against brute force and DoS attacks.
Maintains a comprehensive set of “deny” policy rules to block known attacks, enhancing server security.
Automatically scans file systems for malware injections and cleans infected files, ensuring the integrity of server data.
Features rebootless Secure Kernel powered by KernelCare, which automatically patches kernels without requiring server reboots, maintaining uptime and security.
Analyzes if websites or IPs are blacklisted and provides notifications, helping maintain a positive online reputation
Protects websites running PHP by blocking potentially malicious executions automatically and with zero latency, defending against zero-day attacks
Our Shared Cloud and Reseller Hosting includes Imunify for free and is an option for all Cloud VPS servers.
Imunify360 begins by analyzing all incoming traffic to identify legitimate visitors (e.g., website visitors, search engines, and customers) and blocks potentially harmful sources (e.g., hackers, bots, worms). This ensures that only legitimate traffic reaches the server while malicious actors are stopped at the gate.
Imunify360 applies protection at four main levels: Network, Service/Application, File, and Operating System. Each level has specific tools and defenses to catch and block threats effectively.
Network Level: Includes IP tables and port firewall management to block IP addresses associated with malicious behavior, stopping attacks before they reach the application layer.
Service/Application Level: Imunify360 secures applications such as Apache, Nginx, and PHP by implementing Web Application Firewall (WAF) and ModSecurity to detect and block known vulnerabilities. It also includes proactive defense at the PHP level to stop potential malicious executions in real-time.
File Level: Imunify360 conducts background and real-time scans of files to detect and clean malware. A file antivirus further strengthens this layer, identifying infected files and removing threats.
Operating System Level: The OS is safeguarded through Kernel Live Patching (eliminating the need for reboots) and system updates (such as Yum updates on Linux). This maintains the security of the server kernel and OS-level vulnerabilities without downtime.
In addition to standard protections, Imunify360 includes unique features for enhanced security:
After filtering and multi-layer protection, only legitimate traffic reaches the server, while malicious traffic is blocked. This layered approach ensures the server remains secure from various threats without impacting the performance for genuine users.
In summary, Imunify360 uses a combination of firewall rules, malware scanning, proactive defense mechanisms, and real-time monitoring across different levels of the server architecture to provide a robust security solution for Linux web servers.
You should have Imunify360 on your Linux server for the same reasons you use antivirus software on your computer: to protect against a vast range of cyber threats that can compromise your system, steal data, and disrupt services. Just like your computer is vulnerable to viruses, malware, and hackers, your server faces similar—if not more advanced—threats, as it operates continuously online and is often targeted by attackers seeking to exploit any vulnerabilities.
