KPI (Key Performance Indicator)

A Key Performance Indicator is a quantitative measure used to track progress against a defined objective. In telecom they cover network performance (call setup success rate, drop rate, latency, throughput), service quality, fraud (e.g. high-cost destination spike), and security (signalling firewall hits, authentication failure rate). KPIs feed dashboards and SLA reporting.

KPI in context

Security controls span signaling firewalls (SS7/Diameter/GTP screening), transport encryption (IPsec, TLS, PRINS), identity and access on OSS/BSS, and monitoring at both packet and log level. Controls are audited against GSMA FS.11/FS.19/FS.20/FS.36.

Telecom fraud costs operators an estimated $40+ billion per year. Common vectors include IRSF, Wangiri callback scams, SIM box bypass, PBX hacking and A2P grey routing.

To place KPI in the wider telecom-security picture, review Flash Call, Billing System, Blue Team, CLI Spoofing, Control Plane Security and EDR — each entry cross-references back to this page so you can walk the topic in either direction.
