Abstract
To ensure 5G infrastructure security, standardized Security Assurance Specification (SCAS) tests are being developed by 3GPP. However, executing these tests on complex 5G infrastructures with multiple closed-source network functions (NFs) poses a challenge. This paper presents ScasDK, a development framework that enables third-party test labs to design, deploy, and control SCAS tests on virtualized 5G core infrastructures. ScasDK addresses the multi-NF hurdle by inserting proxies (including custom ones) between NFs and using a central controller to program their responses. Preliminary assessments using seven SCAS tests on three open-source 5G core networks revealed significant test failures, emphasizing the need for enhanced security focus in open-source 5G development.
