ETSI ETR 237:1996 - Security Techniques Advisory Group (STAG) - Baseline security standards - Features and mechanisms

This ETSI Technical Report (ETR) lists all security features and mechanisms that the Security Techniques Advisory  Group  (STAG)  has  evaluated  and  which  may  be  used  in  ETSI  standards.  However,  this  ETR
merely presents guidelines for the selection and application of specific security mechanisms in an annex. If more specific advice is needed, references to relevant sources of information are given. Moreover, the
ETSI STAG experts are ready to assist in case of questions and problems. In many cases, the security mechanisms are not officially standardized themselves, but are registered for use.  Many  of  them  are  not  published  because  of  security  considerations,  but  may  be  used  in  specific ETSI-applications.
