1 Introduction

Diameter Security Application (DSA) allows the home network operator to protect their network from vulnerable Diameter messages. To achieve this, DSA enables the home network operators to define certain configurations, which are used by various countermeasures, for detecting vulnerable Diameter messages from the roaming networks.

DSA menu options allow you to work with:

  • Custom Measurements, Events, Alarms, and Logs (MEALs)
  • General options
  • Trial MPs assignment
  • Application control
  • System Options (SO Only)

DSA is a Diameter Custom Application (DCA) framework application. Like other DCA framework applications, you can use DSA to work with the DCA framework functions. If the Diameter Security Application is visible in the DCA framework GUI menu, the application is already activated and provisioned.

DSA application mainly screens 3GPP S6a/d and 3GPP Gx CCR-I interface messages.
