This paper presents research results on SW security for network elements. The authors' investigations contribute to the ongoing ASMONIA project, which is focusing on collaborative approaches and on protection and warning mechanisms in 4G networks. This paper is dedicated to examine specific aspects thereof, concentrating on SoftWare Integrity Protection (SWIP) to securely manage SW products in mobile networks. Based on an analysis of 3GPP standardization requirements and of existing approaches for integrity protection, solution concepts are proposed and discussed to meet the identified needs. These aim at harmonized approaches for a number of different use cases.
