Secureegenskaper

Secureegenskaper, or security properties, describe the characteristics of a system that determine its ability to protect information and services from threats. They guide the design, implementation, and evaluation of security controls in information systems. A widely used organizing principle is the CIA triad: confidentiality, integrity, and availability. Confidentiality ensures that information is accessible only to authorized parties. Integrity protects data from unauthorized modification and ensures accuracy and trust. Availability guarantees that systems and data are accessible when needed, even in the face of faults or attacks.

Beyond the CIA triad, additional properties are commonly considered, including authenticity (verifying identities), non-repudiation (preventing denial of actions), accountability (traceability of actions), privacy, resilience, and reliability. These properties influence choices in cryptography, access control, authentication, logging, backup and redundancy, and secure development practices.

Assessment of secureegenskaper typically involves threat modeling, risk assessment, and testing such as vulnerability scans and penetration testing. Standards and frameworks relevant to security properties include ISO/IEC 27001 and 27002 for information security management, ISO/IEC 15408 (Common Criteria) for security evaluation, and NIST SP 800-series guidelines. In practice, achieving and maintaining these properties requires ongoing governance, monitoring, and a secure-by-design mindset.

Because threats evolve, secureegenskaper are defined contextually and revisited as systems and environments change, providing a common language for security requirements and assurance.
