I don't understand why TCP must be able to be implemented in a secure fashion. It wasn't designed that way. It would be more useful, IMO, to at least admit that and change the above to acknowledge that, e.g., (changing the wording and the level down to SHOULD): - - TCP SHOULD be able to be implemented in a way that mitigates, to the extent possible, the impact of exploitable conditions leading to: - - Where further protection from exploitable conditions is required, a protocol designed for security may be required; TCP is not intended to serve this purpose, either with or without security extensions.
