AAA security is crucial to the modern telecom network. Here's how the telecom AAA server benefits the operator and mitigates network risks. Device use continues to surge as 5G and the IoT ecosystem become more widespread. Plus, operators now offer more granular and contextual plans for different customers, as well as advanced billing and charging plans for an ever-increasing array of services. As the number of devices connected to a network as well as the services available to them proliferate, networks are more susceptible not only to accounting errors but also to security breaches and threats such as identity theft. AAA assumes a significant role in ensuring security for these dynamically changing network needs.
