IPFire Linux Firewall Distribution Improves Its Intrusion Prevention System

IPFire 2.23 Core Update 139 is the latest release of the Linux-based firewall distribution, featuring an improved Intrusion Prevention System (IPS) that now receives information about which DNS servers are being used by the system, as well as improved booting and reconnect after loss of Internet connection. With this new Core Update, IPFire 2.23 is also switching to AES-GCM as preferred cipher when establishing an SSL/TLS connection to the firewall and connections to web user interface. Previously, the firewall distribution made use of the AES-CBC and ChaCha20/Poly1305 ciphers.
