PECB ISO-IEC-27005-Risk-Manager 問題集

質問 1：
Scenario 5: Detika is a private cardiology clinic in Pennsylvania, the US. Detika has one of the most advanced healthcare systems for treating heart diseases. The clinic uses sophisticated apparatus that detects heart diseases in early stages. Since 2010, medical information of Detika's patients is stored on the organization's digital systems. Electronic health records (EHR), among others, include patients' diagnosis, treatment plan, and laboratory results.
Storing and accessing patient and other medical data digitally was a huge and a risky step for Detik a. Considering the sensitivity of information stored in their systems, Detika conducts regular risk assessments to ensure that all information security risks are identified and managed. Last month, Detika conducted a risk assessment which was focused on the EHR system. During risk identification, the IT team found out that some employees were not updating the operating systems regularly. This could cause major problems such as a data breach or loss of software compatibility. In addition, the IT team tested the software and detected a flaw in one of the software modules used. Both issues were reported to the top management and they decided to implement appropriate controls for treating the identified risks. They decided to organize training sessions for all employees in order to make them aware of the importance of the system updates. In addition, the manager of the IT Department was appointed as the person responsible for ensuring that the software is regularly tested.
Another risk identified during the risk assessment was the risk of a potential ransomware attack. This risk was defined as low because all their data was backed up daily. The IT team decided to accept the actual risk of ransomware attacks and concluded that additional measures were not required. This decision was documented in the risk treatment plan and communicated to the risk owner. The risk owner approved the risk treatment plan and documented the risk assessment results.
Following that, Detika initiated the implementation of new controls. In addition, one of the employees of the IT Department was assigned the responsibility for monitoring the implementation process and ensure the effectiveness of the security controls. The IT team, on the other hand, was responsible for allocating the resources needed to effectively implement the new controls.
Based on scenario 5, which risk treatment option did Detika select to treat the risk of a potential ransomware attack?
A. Risk retention
B. Risk avoidance
C. Risk sharing
正解：A

質問 6：
Scenario 4: In 2017, seeing that millions of people turned to online shopping, Ed and James Cordon founded the online marketplace for footwear called Poshoe. In the past, purchasing pre-owned designer shoes online was not a pleasant experience because of unattractive pictures and an inability to ascertain the products' authenticity. However, after Poshoe's establishment, each product was well advertised and certified as authentic before being offered to clients. This increased the customers' confidence and trust in Poshoe's products and services. Poshoe has approximately four million users and its mission is to dominate the second-hand sneaker market and become a multi-billion dollar company.
Due to the significant increase of daily online buyers, Poshoe's top management decided to adopt a big data analytics tool that could help the company effectively handle, store, and analyze dat a. Before initiating the implementation process, they decided to conduct a risk assessment. Initially, the company identified its assets, threats, and vulnerabilities associated with its information systems. In terms of assets, the company identified the information that was vital to the achievement of the organization's mission and objectives. During this phase, the company also detected a rootkit in their software, through which an attacker could remotely access Poshoe's systems and acquire sensitive data.
The company discovered that the rootkit had been installed by an attacker who had gained administrator access. As a result, the attacker was able to obtain the customers' personal data after they purchased a product from Poshoe. Luckily, the company was able to execute some scans from the target device and gain greater visibility into their software's settings in order to identify the vulnerability of the system.
The company initially used the qualitative risk analysis technique to assess the consequences and the likelihood and to determine the level of risk. The company defined the likelihood of risk as "a few times in two years with the probability of 1 to 3 times per year." Later, it was decided that they would use a quantitative risk analysis methodology since it would provide additional information on this major risk. Lastly, the top management decided to treat the risk immediately as it could expose the company to other issues. In addition, it was communicated to their employees that they should update, secure, and back up Poshoe's software in order to protect customers' personal information and prevent unauthorized access from attackers.
Based on scenario 4, which scanning tool did Poshoe use to detect the vulnerability in their software?
A. Host-based scanning tool
B. Penetration testing tool
C. Network-based scanning tool
