Security Is Now Everyone's Job

A CIO.com column argues the era of centralized security is over, shifting core responsibilities from security specialists to engineering and development teams.

An opinion piece in CIO.com argues that the era of the centralized security team is over. Sparked by industry discussions around Anthropic's AI security projects, the column posits that the key question is no longer just *what* the threats are, but *who* is responsible for defense. The author contends that many critical security tasks—such as identifying exposed systems, decommissioning legacy services, and minimizing API surface area—are now beyond the direct control of a dedicated security team. While security experts can provide guidance and policy, the implementation of these crucial measures falls squarely on the shoulders of the engineering and development teams who build and maintain the systems.

This marks a fundamental transition from a siloed security function to a shared responsibility model, often associated with DevSecOps. In this framework, developers and engineers are not just writing code; they are the primary owners of the security of their applications and infrastructure. The security team's role transforms from that of a gatekeeper to an enabler, focused on providing the tools, training, and automated guardrails that allow engineering teams to operate securely and at speed. This shift requires deep organizational change, fostering a culture where security is integrated into every stage of the development lifecycle, rather than being an afterthought.
