Open APIs in AAA Platforms: The Questions Procurement Forgets to Ask
Evaluating an AAA platform API? Learn four questions procurement teams should ask about API coverage, documentation, rate limits, and testing.
Building a Security Case for AAA Modernization Your CISO Will Sign Off On
Learn how to build a CISO-focused security case for AAA modernization, covering attack surface, compliance, audit risk, and incident response.
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, […]
AAA as a Service: Is Managed AAA Right for Your Network?
AAA as a service – often searched as RADIUS as a service – means a vendor runs your authentication, authorization, and accounting platform: upgrades, patching, monitoring, and the on-call rotation. For ISPs and small CSPs where AAA expertise sits with one or two engineers, the managed model usually buys more reliability than another server would. […]
RADIUS Protocol Explained: How It Secures Telecom Networks
Summary RADIUS (Remote Authentication Dial-In User Service) is the client-server protocol that handles authentication, authorization, and accounting (AAA) for subscribers. A RADIUS server is the central decision point that grants or denies access and meters every session. Architecture: subscriber → NAS (the RADIUS client) → RADIUS server, over UDP ports 1812/1813, secured by a shared […]
Diameter AAA Server for 4G and 5G Networks: A Complete Guide
Every time a subscriber initiates a data session on an LTE or 5G network, the diameter AAA server, the node that handles Authentication, Authorization, and Accounting (AAA) – is the system adjudicating that request before the first packet is forwarded. It validates identity, applies contracted policy, and opens an accounting session for every byte that […]
