Securing the RAN #4: From Security Standards to Operational Defense
A practical guide to operationalizing RAN security through base-station hardening, secure cryptographic and key-management practices, proactive threat detection, telemetry analysis, interface protection, and Zero Trust principles across 5G and O-RAN environments.
Securing the RAN #3: Security in Standardization Evolution from 3G to 5G-Advanced
How 3GPP has systematically hardened RAN security from 3G through 5G-Advanced, from SUCI encryption defeating IMSI catchers to Zero Trust O-RAN interfaces and next-gen protections for IoT, sensing, and satellite networks.
Securing the RAN #2: Attacks on the Radio Interface
This post explores different attack surfaces, attack vectors, and attack scenarios across the RAN, explaining categories of threats and attacker TTPs supported by attack flow illustrations.
Securing the RAN #1: An Introduction
When people talk about mobile network security, the conversation almost always gravitates toward the core network. However, there is another part of the network that quietly sits in public spaces, exposed by design: the Radio Access Network (RAN).
