Study Notes
Assessing Information Security Risk
- Identify the platform or system under assessment.
- Determine the platform's importance to the organization, considering its sensitivity.
- Threat agents could be intentional (hackers) or non-intentional (natural disasters).
- Vulnerabilities include weaknesses in systems, processes, or humans that can be exploited.
- Inherent risk reflects the value of unmitigated risk exposure.
- Understand existing controls and their effectiveness in risk management.
- Residual risk represents the net risk remaining after mitigation efforts.
Qualitative Measures for Risk Level
- Risk severity and likelihood are evaluated in three categories: High, Moderate, Low.
- High severity and high likelihood result in critical risk, necessitating immediate attention.
- The matrix helps identify risk levels, guiding prioritization in addressing vulnerabilities.
Quantitative Risk Formula
- Annualized Loss Expectancy (ALE) is calculated as ALE = Single Loss Expectancy (SLE) * Annual Rate of Occurrence (ARO).
- This formula is less frequently used in cybersecurity due to unreliable data; however, a shift may happen with better data sharing in the industry.
Business Impact of Cyber Attacks
- Attacks lead to immediate and long-term consequences including information disclosure, financial loss, corruption, and reputational damage.
- Legal and regulatory impacts also arise, emphasizing the need for effective risk communication.
Threat Modelling: Reality vs. Expectation
- Despite established frameworks like OCTAVE, many organizations still find threat modeling new and challenging.
- Barriers to implementing threat modeling include lack of tracking documentation, inadequate formal programs, and insufficient internal resources.
Key Questions for Threat Modelling
- Identify who is sponsoring the exercise and the reasons behind it.
- Ensure adequate time for collecting data from diverse sources and understanding dependency issues.
- Define the scope clearly, including whether the focus is organizational-wide or project-specific.
- Determine if there are any specific methodologies mandated by the sponsor, like OCTAVE.
- Organizations often seek external consultancy to prioritize assets at higher risk levels.
Vulnerability Mapping
- Recognize common threat actors, such as crime organizations and nation-states, and typical vulnerabilities they exploit.
- Consider common asset containers like servers, security devices, and infrastructure services affected by vulnerabilities.
- Assess the effectiveness of existing controls against identified scenarios and compile them into a consensus with stakeholders.
Team Collaboration in Risk Assessment
- Engage control owners to evaluate control effectiveness for identified vulnerabilities.
- Consensus among internal stakeholders is crucial for determining residual risk levels within the organization’s risk appetite.
- Workshops facilitate collective decision-making to address biases in risk assessment ratings.
