1 Scope
The present document defines the security assurance of VNFM products, which is part of MANO system. The outcome
of the present document expects the security assets, security threats, security requirements and test cases for evaluating
the security VNFM products. In the present document, the security assurance methodology introduced in 3GPP
specifications will be leveraged. Security test cases including testing goals, testing steps, and evidence of testing results
will be produced for evaluating whether the security requirements are implemented by VNFM based products.
