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.

Install and configure the prerequisites like web servers modules or so.
Configure the Imunify360 integrations like authentication or mod_security configuration.
Install Imunify360.
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.

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.
