Imunify360 version 4.5 released

Feb 4, 2020 8:48:04 PM / by Inessa Atmachian



We’re pleased to announce that a new version of Imunify360, an automated security solution for Linux servers, has been scheduled for gradual roll-out from our production repository and will be available for all customers in about two weeks or less.​ If you’d like to get it earlier, see instruction at the end of the post.

The Imunify360 version 4.5 release introduces the following changes and features:

  • Stand-alone (“no control panel”) version of Imunify360 is now available
    Regular Imunify360 can be installed directly on the server, independent of any panel now.
  • PAM module extension: Exim+Dovecot anti-brute-force
    Comprehensive protection against brute-force IMAP/POP3 attacks targeting Exim+Dovecot.
  • IP management via CLN-based groups
    Block/whitelist particular IPs across a group of servers, and the group is managed in the CLN.
  • Security and performance improvements and fixes

Stand-alone (“no control panel”) version of Imunify360 is now available

Previously, Imunify360 had to be installed through a particular control panel, such as cPanel, DirectAdmin, or Plesk. Now, with version 4.5, it can be installed directly on the server, independent of any panel, regardless of managing interface.

A current version could be run on any CentOS 6/7, Ubuntu 16/18, RHEL 6/7, CloudLinux 6/7 server with Apache web servers.

There are four main steps required for the installation of the Imunify360 in a stand-alone mode on your server.

  1. Install and configure the prerequisites like web servers modules or so.
  2. Configure the Imunify360 integrations like authentication or mod_security configuration.
  3. Install Imunify360.
  4. Change default Imunify360 settings to reflect your needs.

The more details can be found at https://docs.imunify360.com/stand_alone/.

We invite hosting panel developers, VPS and shared hosting providers to start integration with Imunify360 in order to have a comprehensive automated security solution on servers and add more value to the hosting service in general.

Contact our Imunify product team via feedback@imunify360.com for details. We’ll be happy to assist you.

PAM module extension: Exim+Dovecot anti-brute-force

The PAM plugin for Imunify360 (“Pluggable Authentication Module”) now provides protection for Exim+Dovecot components against brute-force IMAP/POP3 attacks.

It counts the number of unsuccessful attempts, and identifies the targets as single- or multiple-user accounts and considers the source of attacks, thus it blocks attackers in a more intelligent way.

IP management via CLN-based groups

Now it’s possible to combine several servers into a management group in the Cloud Linux Network (CLN) and manage IPs in the Imunify360 within that particular group. Just log in with your CLN account, create groups, add some servers to them, and you can block/whitelist particular IPs among the servers in those groups.
