Why Bolting Security Onto Your AAA Server Is Slower Than Building It In
Summary A bolted-on tool (fraud analytics, SIEM rule, detection appliance) sits outside the authentication path. It learns about each RADIUS or Diameter event after the AAA server has already decided, through a log export, an accounting feed, or API polling. Every hop in that chain adds delay and drops detail. By the time a correlation […]
SIM Swap and Subscriber Identity Fraud: The AAA Operator’s Playbook
A SIM swap moves a subscriber’s number onto a SIM the attacker controls. The change is legitimate as far as the network is concerned, which is why it defeats every downstream service that trusts the phone number as proof of identity. Stage 1 (harden verification) lives mostly in the care, retail, and self-service channels: no […]
TACACS+ Privilege Levels and Command Authorization: Building Role-Based Access Across Network Devices
Overview Privilege levels 0, 1 and 15 are a device feature, not an access model, which is how estates decay into “privilege 15 for everyone.” Per-command authorization is the fix: the device checks each command against central policy before running it, so a role becomes an explicit list of permitted commands. Copy the seven-role matrix […]
How AAA Reduces Revenue Leakage in Telecom Networks
A telecom AAA solution decides who gets on the network, what they’re entitled to, and what they used. That third function, accounting, is the raw material every bill is built from. When AAA records are incomplete, duplicated, or disconnected from charging, usage happens that never becomes revenue. This post walks through where AAA-related leakage hides, […]
