A 5G network relies on many new features like SDN/NFV while also introducing other new features such as slicing and MEC. New technologies and features create new challenges for operators in the 5G era to provide security protection for network operation. Moreover, the 5G network supports vertical industries where additional security requirements need to be considered by the 5G network to support vertical business services. Although network operation depends heavily on individual operator’s specific deployment and operations systems, it is still a good practice to build a common security ground for the success of 5G network deployment and operation.

The scope of this document is to:

• Analyse new challenges as well as common security issues for 5G network operation
• Investigate security requirements and guidelines in a technical and/or non-technical way for 5G network operation
