Use cases & scenarios

Compromises

  • Wrong prioritization wastes resources
  • Countermeasures may create new attack surfaces
  • Insufficient testing leads to outages
  • Combine technical and organizational measures
  • Iterative implementation with measurement of effectiveness
  • Involve stakeholders and define clear responsibilities

I/O & resources

  • Risk assessment and asset inventory
  • Operational and architecture diagrams
  • Budget and timeline constraints
  • Implemented technical and organizational controls
  • Test and audit records
  • Updated processes and responsibilities

Description

Countermeasures are targeted actions to reduce risks, vulnerabilities, or adverse impacts in technical systems and organizational processes. They specify preventive, detective, or corrective activities together with responsibilities and effectiveness criteria. Countermeasures are planned and prioritized based on risk analysis, compliance needs, and security architecture considerations.

✔

  • Reduces likelihood and impact of incidents
  • Improves demonstrability for audits and compliance
  • Increases system resilience and operational continuity

✖

  • Countermeasures can increase cost and complexity
  • Not all measures are effective in every environment
  • Lack of acceptance can block implementation

  • Reduction rate of identified vulnerabilities

    Percentage of fixed or mitigated vulnerabilities within a period.

  • Mean Time to Mitigate (MTTM)

    Average time from detection of an issue to successful mitigation.

  • Effectiveness rate (test case success)

    Share of successful tests that demonstrate the expected risk reduction.

Network segmentation for damage containment

Segmenting an internal network into trust zones to limit lateral movement in case of compromise.

Multi-factor authentication after phishing attack

Introducing MFA and reviewing session management after a successful phishing incident.

Rate limiting to mitigate DoS attempts

Implementing API rate limits and traffic shaping to dampen spikes and abuse.

⚠️ Technical debt & bottlenecks

  • Provisional hotfixes without refactoring plan
  • Outdated workarounds that keep vulnerabilities open
  • Insufficient automation of tests and deployments
Staffing for maintenance and monitoringBudget constraints for security investmentsLegacy systems without modern interfaces
  • Blocking legitimate services due to sloppy firewall rules
  • Introducing restrictive controls without emergency processes
  • Only technical measures without organizational embedding
  • Underestimating long-term operational costs
  • Ignoring user feedback after rollout
  • Lack of measurability of effectiveness
