01Security foundations, governance and Chinese context
This domain covers the vocabulary and models that every later domain assumes: what security protects, how it is decomposed, and the formal rules that describe access control. NISP Level 1 questions here are usually definitional, so precision matters more than depth.
917 words, about 5 min02Identity, access and cryptographic protection
This domain tests the identity lifecycle and the mechanisms that turn an identity into an authorised action. Expect questions that separate authentication from authorisation and that ask which access control model fits a scenario.
857 words, about 4 min03Network boundaries and protected communication
This domain tests perimeter architecture and the device behaviour that makes segmentation real. Questions tend to be scenario-based: where a host belongs, which rule is needed, and what a given protocol actually protects.
430 words, about 2 min04Host and operating-system security
This domain tests the hardening baseline of the hosts that hold the data, plus the operational discipline that keeps them hardened. Expect questions on permissions, services, patching and endpoint detection.
398 words, about 2 min05Application and data protection
This domain covers how applications fail and how data is classified and protected through its life. Questions often present a code behaviour or a data-handling scenario and ask for the correct control.
399 words, about 2 min06Security operations, monitoring and response
This domain is about running security as a repeatable service rather than a series of heroic acts. Questions target process ownership, change control and the operational metrics that show the programme is working.
803 words, about 4 min07Vulnerability discovery, prioritization and verification
This domain tests whether you can turn a scanner report into a defensible remediation plan. It separates discovery, prioritisation and verification, and expects you to know the scoring systems and their limits.
381 words, about 2 min08Cyber-risk identification and analysis
IT risk assessment has three phases. Identification builds the inventory: assets, processes, data flows, threats, vulnerabilities, and existing controls, often through risk scenarios ("who or what could exploit which vulnerability, and with what consequence?").
747 words, about 4 min09Continuity, backup and technical recovery
This domain tests continuity planning: how an organisation keeps critical services running during disruption and how it recovers afterwards. Distinguish the continuity plan from the disaster recovery plan and know the time-based metrics precisely.
730 words, about 4 min10Security integration, physical environment and media
Security integration begins with the business service and its protection requirements, not with a product shopping list. Establish scope, assets, users, data flows, trust boundaries, dependencies and operating constraints.
399 words, about 2 min11Cloud, AI and specialized-environment security
The Cloud Security, Risk and Compliance domain tests whether you can place controls correctly across the shared responsibility model and evidence compliance. Questions typically describe a service and ask who owns a control, or which standard or legal obligation applies.
