Risk Analysis

Methodology

The risk analysis follows a structured process, aligned with ISO 27005 and BSI IT-Grundschutz:

Establish context → Identify risks → Analyze risks → Evaluate risks → Treat risks

Threat Catalog

Category	Threats	Relevance
Cyberattacks	Ransomware, phishing, DDoS, APT, supply chain attack	High
Insider threats	Intentional data theft, negligent misuse	Medium
Technical failure	Hardware failure, software defect, network outage	Medium
Natural events	Power outage, flooding, fire	Low
Third parties	Compromise of a service provider, SaaS outage	Medium

Risk Assessment Matrix

Risks are evaluated by likelihood and impact:

	Low Impact	Medium Impact	High Impact	Very High Impact
Very likely	Medium	High	Critical	Critical
Likely	Low	Medium	High	Critical
Possible	Low	Low	Medium	High
Unlikely	Low	Low	Low	Medium

RISK APPETITE

Risks rated Critical or High require immediate treatment. Medium risks must be addressed within the next review cycle. Low risks are monitored and documented.

Risk Treatment Plan

For each identified risk, the following fields are documented:

Field	Description
Risk ID	Unique identifier
Description	Nature of the risk and affected assets
Assessment	Likelihood x Impact
Treatment option	Avoid / Mitigate / Transfer / Accept
Measure	Specific technical or organizational measure
Responsible	Assigned owner
Deadline	Implementation date
Residual risk	Risk level after implementation of measures
Approval	Executive management approval for risk acceptance

Process Integration

Trigger	Action
Annual review cycle	Complete review of all risks
New system / service provider	Risk analysis prior to go-live
Security incident	Event-driven reassessment of affected risks
Significant change	Risk analysis for architectural or process changes
External threat landscape	Reassessment upon relevant CVEs or advisories
