The US National Security Agency (NSA), CISA, and the Office of the Director of National Intelligence (ODNI), have published guidance on ‘Potential Threats to 5G Network Slicing’.
This guidance, created by the Enduring Security Framework (ESF), a public-private cross-sector working group led by the NSA and CISA, presents both the benefits and risks associated with 5G network slicing. It also provides mitigation strategies that address potential threats to 5G network slicing.
According to the guidance, a network slice is ‘an end-to-end logical network that provides specific network capabilities and characteristics to fit a user’s needs. Although multiple network slices run on a single physical network, network slice users are authenticated for only one network area, enabling data and security isolation’.
The guidance ‘intends to introduce 5G stakeholders to the benefits associated with network slicing and introduce perceived risks and management strategies that may address those risks’.
