ISO/IEC 27033: Lead Network Security
The ISO/IEC 27033: Lead Network Security course is an advanced professional program designed to develop the competence required to design, govern, manage, and continually improve network security architectures in alignment with ISO/IEC 27033, the international standard providing guidance on network security controls, design principles, and secure network architecture. ISO/IEC 27033 is published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It complements ISO/IEC 27001 and ISO/IEC 27002 by focusing specifically on network-layer security, including secure network design, segmentation, access control, communication protection, and resilience. This course focuses on leadership and governance rather than device configuration, enabling participants to oversee complex enterprise, cloud, and hybrid network environments. It prepares professionals to operate as senior network security leaders, responsible for aligning network security with business objectives, risk management, and compliance requirements. Course Objectives By the end of this course, participants will be able to: Lead and govern network security programs at an enterprise level Design and evaluate secure network architectures using ISO/IEC 27033 principles Align network security controls with information security risk management Oversee network segmentation, access control, and communication security Integrate network security into ISMS, cloud, and hybrid environments Support audits, assessments, and compliance related to network security Drive continual improvement of network security capabilities
