CRISC Exam Dumps - Certified in Risk and Information Systems Control

When assessing the likelihood that a recently discovered software vulnerability will be exploited, the most important consideration is the skill level required of a threat actor. Here's an explanation:

Skill Level of Threat Actors:

The skill level required to exploit a vulnerability determines how accessible the exploit is to potential attackers.

If a vulnerability requires advanced technical skills to exploit, it is less likely to be targeted by less sophisticated attackers.

Conversely, if the exploit can be easily executed with minimal skills, it increases the likelihood of widespread exploitation.

Factors Influencing Likelihood of Exploitation:

Availability of Exploit Tools:If automated tools or scripts are available to exploit the vulnerability, even less skilled attackers can take advantage of it.

Publication of Exploit Details:If the vulnerability and its exploitation method are widely published, it becomes more accessible to a broader range of attackers.

Assessment of Likelihood:

Security teams assess the skill level required by analyzing whether the exploit is straightforward or complex.

They also consider the presence of exploit kits in the wild that could lower the barrier to entry for potential attackers.

Comparison with Other Factors:

Amount of PII Disclosed:While important, it relates more to the impact rather than the likelihood of exploitation.

Ability to Detect and Trace:This is crucial for response but does not directly influence the likelihood of exploitation.

Amount of Data Exposed:Similar to PII, this factor pertains to the impact rather than the likelihood of exploitation.

ï‚· Understanding Risk Analysis:

Risk analysis involves identifying potential risks associated with a new application and assessing their likelihood and impact on the organization.

It provides a detailed understanding of the potential threats, vulnerabilities, and consequences, enabling informed decision-making.

ï‚· Steps in Conducting a Risk Analysis:

Identify Risks:Determine what risks could arise from the new application, including security vulnerabilities, compliance issues, and operational disruptions.

Assess Risks:Evaluate the likelihood and impact of each identified risk. This includes both qualitative and quantitative assessments.

Prioritize Risks:Rank the risks based on their assessed impact and likelihood to focus on the most significant threats first.

ï‚· Importance of Risk Analysis:

Provides senior management with a comprehensive view of the risks involved, enabling them to make informed decisions about proceeding with the application.

Helps in developing mitigation strategies to address the identified risks.

ï‚· Comparing Other Options:

Perform an Audit:Audits are useful for evaluating existing controls but are not the first step in assessing risks for a new application.

Develop Risk Scenarios:This is part of the risk analysis process but comes after identifying and assessing risks.

Perform a Cost-Benefit Analysis:Important for decision-making but follows the initial risk analysis to understand potential impacts.

ï‚· References:

The CRISC Review Manual emphasizes the importance of conducting a risk analysis to understand and manage risks associated with new applications (CRISC Review Manual, Chapter 2: IT Risk Assessment, Section 2.2.1 Conducting Risk Analysis)​​.

ï‚· Understanding the Question:

The question is about mitigating the impact of social engineering attacks that use AI technology to impersonate senior management personnel.

ï‚· Analyzing the Options:

A. Training and awareness of employees for increased vigilance:This is the most proactive approach. Educating employees about the risks and signs of social engineering attacks enhances their ability to recognize and respond appropriately to such threats.

B. Increased monitoring of executive accounts:Useful but reactive; it doesn't prevent initial attempts.

C. Subscription to data breach monitoring sites:Helps detect breaches but doesn’t directly mitigate impersonation attacks.

D. Suspension and takedown of malicious domains or accounts:Reactive measure and might not be immediate or comprehensive.

ï‚· Detailed Explanation:

Importance of Training:Employees are often the first line of defense against social engineering attacks. Regular training ensures they are aware of the tactics used in such attacks, including those leveraging AI, and how to respond effectively.

Proactive Measure:Training increases vigilance and the likelihood of early detection, reducing the potential impact of the attack.

Business impact analysis (BIA) is the most useful analysis for prioritizing risk scenarios associated with loss of IT assets, because it evaluates the potential consequences of disruption tocritical business functions and processes. BIA helps to identify the most significant risks and the most urgent recovery needs. SWOT analysis, cost-benefit analysis, and root cause analysis are all useful tools for different purposes, but they do not directly address the impact of risk scenarios on business continuity and resilience.

Developing a risk response plan is the best action to address the risk scenarios with high impact and low likelihood of occurrence, because it helps to define and implement the appropriate actions to reduce or eliminate the risk, or to prepare for and recover from the potential consequences. A risk response plan is a document that outlines the strategies and tactics for managing the identified risks, such as avoiding, transferring, mitigating, or accepting the risk. A risk response plan also assigns the roles and responsibilities for the risk owners and stakeholders, and sets the timelines and budgets for the risk response activities. A risk scenario with high impact and low likelihood of occurrence is a rare but severe event that may cause significant disruption or damage to the organization or its objectives, such as a natural disaster, a cyberattack, or a pandemic. Therefore, developing a risk response plan is the best action to address these scenarios, as it helps to minimize the exposure and impact of the risk, and to enhance the resilience and recovery of the organization. Assembling an incident response team, creating a disaster recovery plan (DRP), and initiating a business impact analysis (BIA) are all important actions to perform as part of the risk response plan, but they are not the best action, as they do not cover the whole spectrum of risk response strategies and activities. References = Risk and Information Systems Control Study Manual, Chapter 3, Section 3.4.2, page 103

The risk practitioner’s best course of action after identifying risk scenarios related to noncompliance with new industry regulations is to escalate to senior management, as they have the authority and responsibility to decide on the appropriate risk response and allocate the necessary resources. Transferring the risk, implementing monitoring controls, and recalculating the risk are possible risk responses, but they require senior management approval and direction. References = Risk Scenarios Toolkit, page 19; CRISC Review Manual, 7th Edition, page 107.

Defining recovery time objectives (RTOs) and acceptable data loss thresholds is critical for effective disaster response, ensuring recovery activities are aligned with business priorities. This supportsBusiness Continuity Planning.
