At the most abstract level, security is RISK management which is related to SECRETS management. So, on some level it is true that security is equivalent to obscurity. But, that's like saying that cars are molecules. It is true, but it is not a useful statement.

There are two operative principles of security that you should research. 1) Defense in depth, where there is more than one layer of security that must be pierced. 2) Assume that the attacker knows absolutely everything about your system, design, ports, and so on - except for the key material.
