Latest firewall requirements
Firewall technology has evolved from fixed, black‑box rule sets into flexible, multi‑access security solutions capable of adapting to new threats and new network technologies.

With the rise of signaling‑layer attacks, governments and regulators worldwide are demanding more stringent security measures. Industry bodies such as the GSMA have published new guidelines, including FS.36, to address threats emerging during the transition to 5G Standalone.
