Issue Description

The Network Interpretations Team (NIT) has issued a technical decision regarding FCS_TLSC_EXT.x.1 Test 5e.

Resolution

To align with NIT interpretation #201708 the following changes shall be implemented:

Test 5e is modified as follows:

Test 5: The evaluator shall perform the following modifications to the traffic:
e) Modify a byte in the Server Finished handshake message, and verify that the client sends an Encrypted Message followed by a FIN and ACK message. This is sufficient to deduce that the TOE responded with a Fatal Alert and no further data would be sent.
