MEC Security

In telecom networks, MEC Security covers the controls protecting Multi-access Edge Computing platforms, including isolation between tenant applications, authentication of edge applications to the 5G core (typically as Application Functions), secure exposure APIs, physical security of distributed sites, and integrity of the underlying O-Cloud.

MEC Security in context

The mobile core carries subscriber sessions, mobility and policy. In 4G it is the EPC (MME, HSS, S/PGW); in 5G it is the Service-Based Architecture with AMF, SMF, UPF, AUSF, UDM and the NRF.

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.

To place MEC Security in the wider telecom-security picture, review 5G SBA, ACL, AES, Authorization, CASB and Cipher — each entry cross-references back to this page so you can walk the topic in either direction.
