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 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 threats range from opportunistic SMS phishing and SIM swap to nation-state grade location tracking. The common thread is that most attacks exploit the inherited trust model of legacy signaling protocols.

To place EDR in the wider telecom-security picture, review Slice Security, A5/0, ASN, BGP Hijacking, CASB and Cipher Downgrade Attack — each entry cross-references back to this page so you can walk the topic in either direction.
