EDR (Endpoint Detection and Response)

Endpoint Detection and Response is a security technology that continuously monitors endpoints, workstations, servers, sometimes mobile devices, for behaviours indicative of attack, records detailed telemetry, and supports investigation and remote remediation. EDR is a cornerstone of modern enterprise SOC operations and is increasingly deployed on telecom OSS/BSS infrastructure.

EDR in context

Security controls in telecom span signaling firewalls (SS7/Diameter/GTP screening at the network edge), transport encryption (IPsec, TLS, PRINS), identity and access on OSS/BSS, and monitoring at both the packet and log level. Controls are audited against GSMA FS.11/FS.19/FS.20/FS.36 and, in Europe, NIS2 sectoral rules.

Telecom threats range from opportunistic SMS phishing and SIM swap to nation-state grade location tracking and lawful-interception abuse. The common thread is that most attacks exploit the inherited trust model of legacy signaling. SS7 and Diameter were designed for a closed operator community that no longer exists.

To place EDR in the wider telecom-security picture, review IDS, Slice Security, CASB, Event Logging, IPS and NOC.
