IPFire 2.19 Core Update 104 appears to be a big release with many interesting changes, starting with the latest version of Linux 3.14 kernel, build 3.14.79, and continuing with a brand new Intrusion Prevention System (IPS) called Guardian, and all the latest software updates and security patches. But first, we should warn you that the Linux kernel 3.14 series reached end of life last week, and users are urged to move to Linux 4.4 LTS. As for the new Guardian IPS features, it looks like it’s much faster and efficient than previous implementations, it’s integrated with the Snort IDS (Intrusion Detection System), and has a main goal of automatically blocking access to systems from where malicious traffic was detected. Guardian is also more reliable and makes IPFire a dynamic firewall.
