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.
