1 Scope
The present document contains objectives, requirements and test cases that are specific to the MME network product
class. It refers to the Catalogue of General Security Assurance Requirements and formulates specific adaptions of the
requirements and test cases given there, as well as specifying requirements and test cases unique to the MME network
product class.

document.
- References are either specific (identified by date of publication, edition number, version number, etc.) or

4 MME-specific security requirements and related test
cases
4.1 Introduction
The structure of the present TS 33.116 is aligned with TS 33.117 such that the MME-specific adaptation of a generic
requirement in 33.sas, clause 4.a.b.c.d, can be always found in TS 33.116, clause 4.a.b.c.d. The text on pre-requisites for
testing in clause 4.1.2 of TS 33.117 [3] applies also to the present document.
4.2 MME-specific adaptations of security functional
requirements and related test cases
4.2.1 Introduction

4.2.2 Security functional requirements on the MME deriving from 3GPP
specifications and related test cases
4.2.2.1 Security functional requirements on the MME deriving from 3GPP
specifications – general approach
In addition to the requirements and test cases in TS 33.117, clause 4.2.2, an MME shall satisfy the following:
It is assumed for the purpose of the present SCAS that an MME conforms to all mandatory security-related provisions
pertaining to an MME in:
- 3GPP TS 33.401: "EPS security architecture";
- other 3GPP specifications that make reference to TS 33.401 or are referred to from TS 33.401 (e.g. TS 23.401
[7]).
Security procedures pertaining to an MME are typically embedded in mobility management procedures and are hence
assumed to be tested together with them. Examples include:
- AKA authentication is embedded in an Attach procedure or a TAU procedure.
- Security Mode Control is embedded in an Attach procedure or a TAU procedure.
- The derivation of a mapped security context is embedded in inter-RAT mobili
