The term “protection requirements analysis” refers to the systematic assessment of how much protection information, business processes, applications, IT systems, communication links, or even facilities require. Its purpose is to evaluate the potential damage that could result from impairments to the core security objectives of confidentiality, integrity, and availability, and to derive appropriate security measures from that assessment. In ISMS and BSI IT baseline protection contexts, the related term “determination of protection requirements” is also commonly used. Classifications are typically assigned using categories such as “normal,” “high,” and “very high.”
Asset and structure management: Recording and assigning information, business processes, applications, IT systems, networks, service providers, and other protection objects.
Assessment by security objectives: Evaluating protection requirements separately for confidentiality, integrity, and availability.
Category and criteria catalogs: Using predefined assessment schemes, impact classes, and protection requirement categories for consistent evaluations.
Inheritance and aggregation logic: Automatically transferring protection requirements from business processes and information assets to dependent applications, systems, or infrastructures.
Documentation of damage scenarios: Recording rationales, impacts, and possible consequences of losses in confidentiality, integrity, or availability.
Dependency and impact analysis: Mapping critical connections and dependencies between processes, data, systems, and locations.
Control recommendation and derivation: Linking protection requirement ratings to recommended technical and organizational security measures.
Workflows, approvals, and responsibilities: Supporting review, approval, and update processes including roles and accountability.
Reporting and audit trail: Generating reports, evidence, and change histories for audits, compliance requirements, and management decisions.
Integration into ISMS and GRC environments: Connecting with CMDBs, asset management, risk analysis, control management, and compliance tools.
An HR department classifies payroll and personnel data as having high or very high protection requirements in terms of confidentiality.
A manufacturing company rates production control systems as having high protection requirements for availability because outages can directly cause downtime and financial losses.
A hospital classifies patient records and medical systems as having very high protection requirements, especially with regard to confidentiality and integrity.
A research-driven company rates development documents, design data, or patent applications as having high protection requirements for confidentiality.
An organization reviews critical communication links, such as HR network connections or central business applications, for elevated protection requirements.
