CISO: The Jedi Master of Cybersecurity. Take Off Strong in Your First 100 Days! Detailed Strategic and Tactical Plan.

My personal recommendations on the relevant topics to be addressed, taking a comprehensive approach during the first 100 days of a CISO in office in a new company, framing these topics within a Strategic and tactical planning.

Overview:

The CISO’s first 100 days in office represent a critical window for establishing a solid foundation for information security in the organization. This comprehensive plan provides a detailed roadmap to understand your environment, build key relationships, and achieve tangible results that drive long-term security.

The addition of a new Chief Information Security Officer (CISO) represents a crucial opportunity to strengthen an organization’s information security posture. This detailed plan provides strategic and tactical guidance for the CISO’s first 100 days, focused on establishing a solid foundation, understanding the current environment, and achieving tangible results that drive long-term security.

Strategic Objectives:

1. Establish strong, long-lasting relationships: Build trust and collaboration with key stakeholders, including senior management, IT leaders, security teams, auditors (internal and external), legal and compliance departments, and other relevant areas. Implement effective communication channels to ensure a transparent and two-way flow of information.
2. Comprehensive current state assessment: Conduct a comprehensive analysis of the risk landscape, including internal and external threats, technical and human vulnerabilities, and third-party risks. Assess security maturity by reviewing policies, procedures, network architecture, incident reports, risk assessments, and business continuity plans. Identify regulatory compliance gaps and priority areas of improvement.
3. Define a clear, ambitious and aligned vision: Develop a long-term strategic information security plan that aligns with the strategic objectives of the business, considering emerging trends in cybersecurity and best practices in the sector. Set SMART (Specific, Measurable, Achievable, Relevant, Time-bound) goals and define key metrics to measure program success.
4. Achieve tangible quickwins: Identify and implement high-impact, low-effort projects that can generate visible and measurable results in the short term. These projects may include patch management improvements, strengthening authentication, implementing security awareness programs, or reviewing critical policies. Communicate achievements effectively to build trust and gain stakeholder support.
