Introduction

Imunify360 is the security solution for Linux web servers based on machine learning technology which utilizes a multi-layer approach to provide total protection against any types of malicious attacks or abnormal behavior including distributed brute force attacks.

Imunify360 provides:

  • Advanced firewall with cloud heuristics and artificial intelligence for detecting new threats and protecting all servers that run the software -  capable of defending against brute force attacks, DoS attacks.

  • Intrusion Detection and Protection System -  comprehensive collection of “deny” policy rules for blocking all known attacks.

  • Malware Scanning - automatic scanning file systems for malware injection and cleaning up infected files.

  • Patch Management - rebootless Secure Kernel powered by KernelCare keeps the server secure by automatically patching kernels without having to reboot the server.

  • Website Reputation Monitoring - analyzing if web-site or IPs are blocked by any blacklists and notifying if they are.

  • Proactive Defense - Proactive Defense protects websites running PHP, against zero-day attacks by blocking potentially malicious executions automatically and with zero latency.

If a user violates Imunify360 security rules (trying to enter a wrong password, etc.), then Imunify360 will automatically block the access to this user IP-address, adding the IP-address to the Gray List.

If, after that, a user will try to access the HTTP/S port (#80/443), he will see the [Anti-bot Challenge](/features/#Anti-bot Challenge). After entering the Anti-bot Challenge correctly, Imunify360 will remove that user from the Gray List. In a case of repeated violation, the IP address will be automatically added to the Gray List again.

An administrator can remove any IP-address from the Gray List and add to the White List if needed. In this case, the user will not be blocked when attempting to violate Imunify360 security rules.
