Complexity is the real vulnerability
Security is a unique IT discipline. It overlays and supports all other disciplines: computers, networks, storage, apps, data. As IT evolves, so does IT security (often with a considerable lag). The introduction of personal computing gave rise to endpoint protection suites and AV capabilities. Networks drove the introduction of the firewall. Applications spawned multiple security disciplines from two-factor authentication to secure app development, vulnerability scanning and web application firewalls. Databases introduced encryption and activity monitoring – and to manage all these capabilities we now have Security Information and Event Management (SIEM) platforms.
