Oversee threat detection, vulnerability management (with SLA-based performance tracking), and incident response. Establish a guardrail-based controls model for cloud and container workloads.
- Product Security: Embed secure-by-design principles across engineering workflows, integrating security early and consistently throughout the SDLC, including secure coding standards, penetration testing, bug bounty programs, and security requirements for AI/ML components (model integrity, training data protection, prompt injection prevention, output validation).
- AI Security & Governance: Establish enterprise AI governance (acceptable use, data loss prevention for AI inputs, vendor risk assessments for third-party AI services). Build detection and response capabilities for AI-powered attack vectors. Drive adoption of AI and automation across the security function, including AI-assisted threat detection, automated incident response, and intelligent vulnerability prioritization.
