Scenario 2: Travivve is a travel agency that operates in more than 100 countries. Headquartered in San Francisco, the US, the agency is known for its personalized vacation packages and travel services. Travivve aims to deliver reliable services that meet its clients' needs. Considering the impact of information security in its reputation, Travivve decided to implement an information security management system (ISMS) based on ISO/IEC 27001. In addition, they decided to establish and implement an information security risk management program. Based on the priority of specific departments in Travivve, the top management decided to initially apply the risk management process only in the Sales Management Department. The process would be applicable for other departments only when introducing new technology.
Travivve's top management wanted to make sure that the risk management program is established based on the industry best practices. Therefore, they created a team of three members that would be responsible for establishing and implementing it. One of the team members was Travivve's risk manager who was responsible for supervising the team and planning all risk management activities. In addition, the risk manager was responsible for monitoring the program and reporting the monitoring results to the top management.
Initially, the team decided to analyze the internal and external context of Travivve. As part of the process of understanding the organization and its context, the team identified key processes and activities. Then, the team identified the interested parties and their basic requirements and determined the status of compliance with these requirements. In addition, the team identified all the reference documents that applied to the defined scope of the risk management process, which mainly included the Annex A of ISO/IEC 27001 and the internal security rules established by Travivve. Lastly, the team analyzed both reference documents and justified a few noncompliances with those requirements.
The risk manager selected the information security risk management method which was aligned with other approaches used by the company to manage other risks. The team also communicated the risk management process to all interested parties through previously established communication mechanisms. In addition, they made sure to inform all interested parties about their roles and responsibilities regarding risk management. Travivve also decided to involve interested parties in its risk management activities since, according to the top management, this process required their active participation.
Lastly, Travivve's risk management team decided to conduct the initial information security risk assessment process. As such, the team established the criteria for performing the information security risk assessment which included the consequence criteria and likelihood criteria.
Did the risk management team establish all the criteria required to perform the information security risk assessment? Refer to scenario 2.
A. Yes. the risk management team established all the criteria that are necessary to perform an information security risk assessment
B. No, the risk management team should also establish the criteria for treating the identified risks
C. No, the risk management team should also establish the criteria for determining the level of risk

Scenario 8: Biotide is a pharmaceutical company that produces medication for treating different kinds of diseases. The company was founded in 1997, and since then it has contributed in solving some of the most challenging healthcare issues.
As a pharmaceutical company, Biotide operates in an environment associated with complex risks. As such, the company focuses on risk management strategies that ensure the effective management of risks to develop high-quality medication. With the large amount of sensitive information generated from the company, managing information security risks is certainly an important part of the overall risk management process. Biotide utilizes a publicly available methodology for conducting risk assessment related to information assets. This methodology helps Biotide to perform risk assessment by taking into account its objectives and mission. Following this method, the risk management process is organized into four activity areas, each of them involving a set of activities, as provided below.
1. Activity area 1: The organization determines the criteria against which the effects of a risk occurring can be evaluated. In addition, the impacts of risks are also defined.
2. Activity area 2: The purpose of the second activity area is to create information asset profiles. The organization identifies critical information assets, their owners, as well as the security requirements for those assets. After determining the security requirements, the organization prioritizes them. In addition, the organization identifies the systems that store, transmit, or process information.
3. Activity area 3: The organization identifies the areas of concern which initiates the risk identification process. In addition, the organization analyzes and determines the probability of the occurrence of possible threat scenarios.
4. Activity area 4: The organization identifies and evaluates the risks. In addition, the criteria specified in activity area 1 is reviewed and the consequences of the areas of concerns are evaluated. Lastly, the level of identified risks is determined.
The table below provides an example of how Biotide assesses the risks related to its information assets following this methodology:
Based on the scenario above, answer the following question:

Which risk assessment methodology does Biotide use?
A. OCTAVE-S
B. OCTAVE Allegro

Scenario 6: Productscape is a market research company headquartered in Brussels, Belgium. It helps organizations understand the needs and expectations of their customers and identify new business opportunities. Productscape's teams have extensive experience in marketing and business strategy and work with some of the best-known organizations in Europe. The industry in which Productscape operates requires effective risk management. Considering that Productscape has access to clients' confidential information, it is responsible for ensuring its security. As such, the company conducts regular risk assessments. The top management appointed Alex as the risk manager, who is responsible for monitoring the risk management process and treating information security risks.
The last risk assessment conducted was focused on information assets. The purpose of this risk assessment was to identify information security risks, understand their level, and take appropriate action to treat them in order to ensure the security of their systems. Alex established a team of three members to perform the risk assessment activities. Each team member was responsible for specific departments included in the risk assessment scope. The risk assessment provided valuable information to identify, understand, and mitigate the risks that Productscape faces.
Initially, the team identified potential risks based on the risk identification results. Prior to analyzing the identified risks, the risk acceptance criteria were established. The criteria for accepting the risks were determined based on Productscape's objectives, operations, and technology. The team created various risk scenarios and determined the likelihood of occurrence as "low," "medium," or "high." They decided that if the likelihood of occurrence for a risk scenario is determined as "low," no further action would be taken. On the other hand, if the likelihood of occurrence for a risk scenario is determined as "high" or "medium," additional controls will be implemented. Some information security risk scenarios defined by Productscape's team were as follows:
1. A cyber attacker exploits a security misconfiguration vulnerability of Productscape's website to launch an attack, which, in turn, could make the website unavailable to users.
2. A cyber attacker gains access to confidential information of clients and may threaten to make the information publicly available unless a ransom is paid.
3. An internal employee clicks on a link embedded in an email that redirects them to an unsecured website, installing a malware on the device.
The likelihood of occurrence for the first risk scenario was determined as "medium." One of the main reasons that such a risk could occur was the usage of default accounts and password. Attackers could exploit this vulnerability and launch a brute-force attack. Therefore, Productscape decided to start using an automated "build and deploy" process which would test the software on deploy and minimize the likelihood of such an incident from happening. However, the team made it clear that the implementation of this process would not eliminate the risk completely and that there was still a low possibility for this risk to occur. Productscape documented the remaining risk and decided to monitor it for changes.
The likelihood of occurrence for the second risk scenario was determined as "medium." Productscape decided to contract an IT company that would provide technical assistance and monitor the company's systems and networks in order to prevent such incidents from happening.
The likelihood of occurrence for the third risk scenario was determined as "high." Thus, Productscape decided to include phishing as a topic on their information security training sessions. In addition, Alex reviewed the controls of Annex A of ISO/IEC 27001 in order to determine the necessary controls for treating this risk. Alex decided to implement control A.8.23 Web filtering which would help the company to reduce the risk of accessing unsecure websites. Although security controls were implemented to treat the risk, the level of the residual risk still did not meet the risk acceptance criteria defined in the beginning of the risk assessment process. Since the cost of implementing additional controls was too high for the company, Productscape decided to accept the residual risk. Therefore, risk owners were assigned the responsibility of managing the residual risk.
Based on the scenario above, answer the following question:
Which risk treatment option was used for the first risk scenario?
A. Risk avoidance
B. Risk modification
C. Risk sharing
