I would agree that effective protection includes physical as well as software controls employed in combination. Physical controls like locks, guards, and fire alarms bar unauthorized access and protect against environmental hazards, whereas software controls like firewalls, encryption, and security patches protect against cyber attacks. I also like your insistence on layered security—protecting only one layer of protection leaves the system open to vulnerabilities in other areas. A comprehensive, multi-phased approach ensures that a network is resistant to a wide variety of threats, from human error to the most sophisticated cyberattacks.
