Frequently asked questions about IT Risks

What are IT risks and how are they classified?

IT risks manifest as a product of threats, vulnerabilities, and potential impacts on a company's information technology. They can be classified along various dimensions:

🔍 Classification according to BSI:

• **Internal/External**: Internal risks arise within the organisation (e.g. human error, system failures), while external risks come from outside (e.g. cyberattacks, natural disasters)
• **Direct/Indirect**: Direct risks affect IT systems immediately; indirect risks operate through third parties (e.g. supply chain attacks)
• **Controllable/Uncontrollable**: Some risks can be mitigated through controls; others (such as geopolitical cyber conflicts) are barely manageable

📊 Classification by risk type:

• **Technical risks**: Hardware failures, software errors, network issues
• **Organisational risks**: Inadequate processes, unclear responsibilities
• **Personnel risks**: Misuse, social engineering, insider threats
• **Physical risks**: Fire, water, power outages, physical access
• **Compliance risks**: Violations of laws and regulations (GDPR, NIS2)

⚠ ️ Classification by impact:

• **Confidentiality**: Unauthorised access to sensitive data
• **Integrity**: Manipulation or falsification of data
• **Availability**: Failure or restriction of IT services
• **Authenticity**: Identity misuse or spoofed systems

🌐 Current threat landscape:

• According to the Allianz Risk Barometer, cyber incidents dominate the risk landscape with 47% of mentions
• 58% of cyberattacks are carried out by external actors
• Supply chain attacks via software supply chains caused 41% of indirect damages in 2024• 27% of KRITIS operators classify geopolitical cyber conflicts as an existential threat

What methods are used to assess IT risks?

IT risk assessment uses a combination of qualitative and quantitative methods, applied differently depending on company size and industry:

📋 Qualitative methods:

• **Risk matrix**: Correlation of probability of occurrence and extent of damage in a matrix (e.g. 5x5)
• **Expert interviews**: Structured interviews with subject matter experts for risk assessment
• **Scenario analyses**: Development and evaluation of risk scenarios (best/worst case)
• **SWOT analysis**: Assessment of strengths, weaknesses, opportunities, and risks
• **Delphi method**: Multiple anonymous rounds of expert surveys with feedback

🔢 Quantitative methods:

• **Annual Loss Expectancy (ALE)**: Calculation of the expected annual loss
• ALE = Single Loss Expectancy (SLE) × Annual Rate of Occurrence (ARO)
• Example: €250,000 (damage per incident) × 0.33 (frequency) = €82,500 per year
• **Value at Risk (VaR)**: Statistical method for determining maximum loss
• **Monte Carlo simulations**: Stochastic simulation of various risk scenarios
• **Bayesian networks**: Modelling of cause-and-effect relationships

🔄 Hybrid approaches:

• **FAIR (Factor Analysis of Information Risk)**: Combination of qualitative and quantitative elements
• **OCTAVE (Operationally Critical Threat, Asset, and Vulnerability Evaluation)**: Multi-stage process with qualitative and quantitative components
• **NIST Risk Management Framework**: Comprehensive framework with various assessment methods

📊 Industry-specific benchmarks:

• According to Bitkom studies, the median ALE value for German mid-sized companies is €1.2 million p.a.
• 68% of companies report difficulties in calibrating risk scales
• The average cost of a data breach in Germany is €4.45 million (IBM Cost of a Data Breach Report)
