The contents of the present document are subject to continuing work within the TSG and may change following formal
TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an
identifying change of release date and an increase in version number as follows:
Version x.y.z
where:
x the first digit:
1 presented to TSG for information;
2 presented to TSG for approval;
3 or greater indicates TSG approved document under change control.
y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
updates, etc.
z the third digit is incremented when editorial only changes have been incorporated in the document.

1 Scope
The present document contains objectives, requirements and test cases that are deemed applicable, possibly after
adaptation, to several network product classes.
Several network product classes share very similar if not identical security requirements for some aspects. Therefore,
these are collected in this "catalogue" document applicable to many network product classes. In addition to this
catalogue, requirements specific to different network product classes will be captured in separate documents.

Machine Accounts: These will be used for authentication and authorization from system to system or between
applications on a system and cannot be assigned to a single person or a group of persons.
Personal data: any information relating to an identified or identifiable natural person ('data subject').
Identifiable person: one who can be identified, directly or indirectly, in particular by reference to an identification
number, name or to one or more factors specific to his physical, physiological, mental, economic, cultural or social
identity.
NOTE: personal data can be gathered from user data and traffic data.
Sensitive data: data that may be used for authentication or may help to identify the user, such as user names,
passwords, PINs, cryptographic keys, IMSIs, IMEIs, MSISDNs, or IP addresses of the UE, as well
