How to Install and Uninstall Imunify360?

Imunify360 is an automated security solution with multi-layer defense architecture for Linux based web servers. Immunify360 utilizes a multi-layer approach to provide complete protection against any malicious attacks or abnormal behavior like a brute force attack. Immunify360 includes all features of Immunity AV+ as well as advanced firewalls, intrusion detection, and protection system, malware scanning, patch management, proactive defense, and more. The modular and integrated organization of Immunify360 makes it scale with your needs and provides a secure and reliable web server. Its architecture helps to ensure precise targeting and eradication of viruses and malware. In this tutorial, we will see how to install Imunify360.

If any user violates Immunify360 security rules, such as entering the wrong password, then Immunify360 automatically blocks that user’s IP address. Immunify360 adds that IP address to the Gray List. If you want to remove your blocked IP from the Gray List, then access the HTTP (#80) or HTTPS (#443) Port and enter the CAPTCHA correctly. If this IP repeats the violation of security rules, then the IP gets added to the Gray List again. An administrator can remove the IP from the Gray List and add that to the White List. If the IP gets added to the White List, then the user won’t be blocked even after they violate Immunify360 security rules.

Imunify360 provides an Ignore List in which you can mention all the files and folders which need to get ignored during an automatic or manual malware scan. The Imunify360 central server is a third-party application that serves as a sensor to detect suspicious activities on your server.
