NFV-Related Attack Vectors in 5G
Network Function Virtualization (NFV) is a core technology in 5G networks that introduces specific security challenges and attack vectors. The ENISA report on "NFV Security in 5G" highlights several key vulnerabilities in this area. [^2]
Virtualization Layer Attacks
Targeting hypervisors, container runtimes, and virtualization infrastructure to compromise network functions.
Orchestration and Management Attacks
Exploiting vulnerabilities in NFV MANO components to manipulate network function deployment and configuration.
Multi-Tenancy Vulnerabilities
Breaching isolation between different tenants sharing the same NFV infrastructure.
