Fundamental concepts and principles of IoT security
Define IoT ecosystem components, device classes, and reference architectures (edge, gateway, cloud) from ISO/IEC 27400 and related standards.
Explain the core security properties (confidentiality, integrity, availability, privacy) as applied to constrained devices and long-lived deployments.
Identify the principal threat agents, attack surfaces, and lifecycle stages (concept, design, development, operation, decommissioning) that shape IoT risk.
Map at least five real-world IoT incident patterns (e.g., botnets, default credentials, insecure update channels) to the concepts in Domain 1.
Your checkpoint
A one-page concept map linking IoT components, lifecycle stages, security properties, and threat categories, with a short rationale for each link.
Fundamental concepts and principles of IoT security & ISO/IEC 27400 IoT security controls and risk management
Describe the structure and intent of ISO/IEC 27400 and how it relates to ISO/IEC 27001 and other IoT guidance.
Classify the ISO/IEC 27400 control areas (e.g., governance, asset management, access control, cryptography, update management) and explain the purpose of each.
Relate each control area to the corresponding risk treatment options (avoid, mitigate, transfer, accept) in an IoT context.
Draft risk scenarios for a representative IoT deployment (smart building or industrial sensor network) and match them to specific ISO/IEC 27400 controls.
Your checkpoint
A control-to-risk matrix with at least 10 IoT risk scenarios mapped to ISO/IEC 27400 control areas and proposed treatment options.
ISO/IEC 27400 IoT security controls and risk management
Apply a structured IoT risk assessment process (asset identification, threat modeling, vulnerability analysis, likelihood and impact estimation) to a chosen scenario.
Evaluate the suitability of ISO/IEC 27400 controls against identified risks, including dependencies and residual risk.
Document risk treatment decisions with justification and assign ownership for each control.
Identify constraints specific to IoT (constrained devices, physical exposure, long support life) that affect control selection.
Your checkpoint
A risk assessment report for a fictional IoT deployment including asset inventory, threat model, risk register with at least 12 entries, and treatment plan referencing ISO/IEC 27400 controls.
Planning an IoT security program based on ISO/IEC 27400
Define scope, objectives, and success criteria for an IoT security program aligned with organizational strategy and ISO/IEC 27400.
Develop a governance structure specifying roles, responsibilities, and decision rights for IoT security across IT, OT, and product teams.
Create a high-level implementation roadmap that sequences controls by risk priority, feasibility, and lifecycle stage.
Establish a policy framework (acceptable use, secure development, third-party management, incident response) that anchors the program.
Your checkpoint
An IoT security program charter and 12-month roadmap covering scope, governance roles, prioritized control implementation phases, and policy list.
Planning an IoT security program based on ISO/IEC 27400 & Implementing and operating IoT security controls
Translate the program roadmap into detailed implementation plans for at least three control areas (e.g., identity and access management, secure configuration, update management).
Specify technical and procedural requirements for device onboarding, credential management, and secure decommissioning.
Design monitoring and logging requirements for IoT environments, including what to collect, where to store it, and retention periods.
Identify required resources, skills, and third-party dependencies for the implementation plan.
Your checkpoint
Three detailed implementation plans (one per control area) with tasks, owners, timelines, resource estimates, and acceptance criteria.
Implementing and operating IoT security controls
Implement a secure configuration baseline for a representative IoT device class and document verification steps.
Establish an access control model (roles, least privilege, segregation of duties) for IoT management interfaces and back-end services.
Define and test an update and patch management process, including rollback and integrity verification.
Operate an incident response exercise for an IoT-specific scenario (e.g., compromised sensor, credential leak) and capture lessons learned.
Your checkpoint
A configuration baseline document, access control matrix, update process flowchart, and incident response exercise report with findings.
Implementing and operating IoT security controls & Monitoring, reviewing, and continually improving IoT security
Define key performance indicators (KPIs) and key risk indicators (KRIs) to measure IoT security control effectiveness.
Design a monitoring and review cycle (dashboards, log reviews, vulnerability scans, compliance checks) with clear frequencies and owners.
Plan an internal audit or assessment of the IoT security program against ISO/IEC 27400 controls.
Identify improvement mechanisms (corrective actions, management review, lessons learned) and integrate them into the program.
Your checkpoint
A monitoring and review plan including KPI/KRI definitions, review schedules, audit checklist, and a corrective action log template.
Monitoring, reviewing, and continually improving IoT security
Conduct a simulated management review using the monitoring data and audit findings from Week 7.
Produce a continual improvement plan with prioritized actions, owners, and target dates.
Consolidate all deliverables into a coherent program summary aligned to ISO/IEC 27400 domains.
Complete a timed practice assessment covering all five domains and analyze gaps for final review.
Your checkpoint
A management review report and continual improvement plan, plus a personal gap analysis from the practice assessment with a final revision checklist.
