• Define and govern the enterprise cybersecurity architecture frameworks, standards, reference architectures, and security control patterns to protect enterprise IT, cloud, and digital platforms, ensuring alignment with enterprise security principles and regulatory requirements.
• Define and govern cybersecurity architecture standards, processes, and best practices across identity & access management (IAM), network security, application security, cloud security, data protection, and endpoint security to enable a secure-by-design enterprise ecosystem.
• Develop risk-driven and optimization-focused security solution architectures, providing domain-specific high-level architectural guidance to mitigate cyber risks, address security gaps, improve resilience, and optimize security investments.
• Authorized to review, endorse, and co-sign cybersecurity architecture blueprints for all systems, platforms, and solutions to ensure compliance with enterprise cybersecurity architecture and security governance.
• Maintain and update the Architecture Repository with cybersecurity architecture artifacts, threat models, security patterns, and the cybersecurity architecture roadmap.
• Define and maintain cybersecurity architecture principles, frameworks, guidelines, and roadmaps in alignment with group-level Architecture Governance & Enablement functions, providing architectural oversight across all group subsidiaries.
• Manage end-to-end cybersecurity architectural engagements, including security blueprinting, threat modeling, and risk assessments, identifying gaps between As-Is and To-Be security architectures and defining transition roadmaps.
• Evaluate and assess current-state security architectures and define target-state cybersecurity architectures for specific business, technology, and regulatory domains.
• Support Technology Excellence & Control functions by translating cybersecurity architecture roadmaps into executable programs, initiatives, and security controls.
• Evaluate and review technical and architectural proposals (RFIs, RFPs, vendor solutions) from a cybersecurity perspective, providing expert recommendations and risk-based insights.
• Develop, maintain, and govern cybersecurity reference architectures, policies, standards, and design guidelines for enterprise and line-of-business domains, supported by continuous threat intelligence, market analysis, and emerging technology trends.
• Identify and conduct cybersecurity efficiency and optimization studies, translating findings into roadmap initiatives with measurable risk reduction and cost optimization outcomes.
• Support architecture-related change management and governance forums, including ARB decisions, security exception reviews, RFP evaluations, and architecturally significant change requests.
• Provide cybersecurity architectural oversight for demand management reviews, ensuring new initiatives, platforms, and business capabilities align with enterprise security strategy and risk appetite.
• Define architectural standards and enablement frameworks for cloud security, Zero Trust, DevSecOps, and secure software supply chain practices, ensuring scalable and compliant adoption across the organization.
• Define and govern cybersecurity architecture requirements for AI, ML, and GenAI platforms, including model security, data protection, identity controls, secure pipelines, and protection against emerging AI-related threats.
