Sicherheitsanalysewerkzeuge

Sicherheitsanalyse, or security analysis in German, is a systematic process used to identify, evaluate, and mitigate risks to people, information, assets, and operations. It combines asset identification, threat assessment, vulnerability discovery, and impact estimation to support decision‑making and prioritization of security measures.

It can be applied across domains such as information security, physical security, and operational risk management. Analyses may be qualitative, relying on expert judgment, or quantitative, using numerical data and probabilistic models. The choice of approach depends on objectives, available data, and risk tolerance.

Common frameworks and methods include ISO/IEC 27005 for information security risk management, NIST SP 800-30, and alternative models like OCTAVE and FAIR. Threat modeling techniques (such as STRIDE or PASTA) help identify how threats could exploit weaknesses. Security controls and countermeasures are selected and evaluated for effectiveness and cost.

A typical Sicherheitsanalyse follows scoping, asset identification, threat modeling, vulnerability assessment, risk estimation, and risk treatment. Results are summarized in a risk register and accompanied by a prioritized set of recommendations, cost-benefit analyses, and an implementation plan. Ongoing monitoring and reassessment are essential due to changing threats.

In practice, Sicherheitsanalyse supports compliance with standards, informs design and operation of security programs, and aligns security with business goals. Limitations include uncertainty in threat likelihood, evolving attack techniques, data quality, and resource constraints. It is most effective as an iterative process integrated with governance, incident response, and business continuity planning.
