Mission Overview

This is a consultancy mission at a client site, representing Keystone Solutions. As a Senior Initiative Owner for Cyber Security Strategy (Post-Quantum Readiness), you will be hired by Keystone Solutions to deliver strategic and technical leadership on client projects in the field of information security.

Responsibilities

• Define cyber security initiative strategy, including emerging threats like post-quantum risks, and translate it into a prioritized portfolio (projects, enhancements, studies).
• Oversee purpose, value, status, and cross-dependencies of all portfolio items to ensure collective achievement of business outcomes.
• Act as a strategy/initiative owner and drive the day-to-day delivery of the roadmap, ensuring impediments (including PQC transition challenges) are efficiently resolved.
• Engage diverse stakeholders to co-develop strategy, roadmaps, and key actions—balancing traditional and quantum-resistant security measures.
• Deliver bank-wide roadmaps and investment priorities, requiring strong communication with middle/senior management across all functions.

Function Description: Responsibilities & Key Tasks

• Develop high-level term roadmaps and detailed short/medium-term roadmaps with priority actions and budgets, accounting for long-term cryptographic resilience (e.g., PQC migration timelines).
• Collaborate with Group to roll out standard solutions, balancing business needs with quantum-safe security requirements.
• Direct all phases of cyber security initiatives, including PQC readiness assessments and mitigation planning.
• Prioritize workstreams aligned with overall security objectives, ensuring cryptographic agility is embedded in project designs.
• Set milestones, ensure adherence to master plans, and mitigate risks/issues—proactively flagging PQC-specific dependencies (e.g., vendor support, legacy system constraints).
• Challenge roadmaps with technical awareness of PQC standards (e.g., NIST-selected algorithms) and strategic oversight.
• Regularly interact with senior/executive management on cross-functional topics, including quantum risk awareness and investment justification.
• Aggregate stakeholder input into deliverables (e.g., memos on PQC transition impacts for Sr. Management/ExCo).
• Ensure initiatives align with Group standards, regulations, and evolving cryptographic policies (e.g., ETSI/IETF PQC guidelines).
• Contribute to policy improvements (e.g., quantum-safe data security frameworks) with relevant teams.
