Distributed Slice Mobility Attack: A Novel Targeted Attack Against Network Slices of 5G Networks
Vipin N. Sathi, C. Siva Ram Murthy · IEEE Networking Letters · 2020
Inter-slice mobility in 5G networks allows mobility of user sessions from one network slice to another. In this letter, we propose a novel targeted attack against network slices of 5G networks by exploiting the user equipment-initiated inter-slice mobility. We name this attack as distributed slice mobility (DSM) attack. We show that the performance and economic damage caused by the DSM attack is higher than the denial-of-service and Yo-Yo attacks. We also suggest a few defense strategies to reduce the performance damage caused by the DSM attack.
