  • Question 83:

    Scenario 2: Knight is an electronics company from Northern California, US that develops video game consoles. Knight has more than 300 employees worldwide. On the fifth anniversary of their establishment, they have decided to deliver the

    G-Console, a new generation video game console aimed for worldwide markets. G-Console is considered to be the ultimate media machine of 2021 which will give the best gaming experience to players.

    The console pack will include a pair of VR headset, two games, and other gifts.

    Over the years, the company has developed a good reputation by showing integrity, honesty, and respect toward their customers. This good reputation is one of the reasons why most passionate gamers aim to have Knight's G-console as

    soon as it is released in the market.

    Besides being a very customer-oriented company, Knight also gained wide recognition within the gaming industry because of the developing quality. Their prices are a bit higher than the reasonable standards allow.

    Nonetheless, that is not considered an issue for most loyal customers of Knight, as their quality is top-notch.

    Being one of the top video game console developers in the world, Knight is also often the center of attention for malicious activities. The company has had an operational ISMS for over a year. The ISMS scope includes all departments of

    Knight, except Finance and HR departments.

    Recently, a number of Knight's files containing proprietary information were leaked by hackers. Knight's incident response team (IRT) immediately started to analyze every part of the system and the details of the incident.

    The IRT's first suspicion was that Knight's employees used weak passwords and consequently were easily cracked by hackers who gained unauthorized access to their accounts. However, after carefully investigating the incident, the IRT

    determined that hackers accessed accounts by capturing the file transfer protocol (FTP) traffic.

    FTP is a network protocol for transferring files between accounts. It uses clear text passwords for authentication.

    Following the impact of this information security incident and with IRT's suggestion, Knight decided to replace the FTP with Secure Shell (SSH) protocol, so anyone capturing the traffic can only see encrypted data.

    Following these changes, Knight conducted a risk assessment to verify that the implementation of controls had minimized the risk of similar incidents. The results of the process were approved by the ISMS project manager who claimed that

    the level of risk after the implementation of new controls was in accordance with the company's risk acceptance levels.

    Based on this scenario, answer the following question:

    Based on scenario 2, the ISMS project manager approved the results of risk assessment. Is this acceptable?

    A. No, the risk remaining after the treatment of risk should be approved by the top management at any stage
    B. No, the risk remaining after the implementation of new controls for the ISMS should be approved by the ISMS team
    C. Yes, the risk remaining after the treatment of risk should be approved by the ISMS project manager

    B. Audit criteria should be used to assess objective evidence in order to generate audit outcomes. Then, the audit report should be created and presented to the audit team leader at the closing meeting.
    C. Audit methods should be used to assess audit evidence in order to generate audit recommendations. Then, the audit recommendations should be created and presented to the auditee at the closing meeting.
    D. Audit methods should be used to assess objective evidence in order to generate audit findings. Then, the audit conclusion should be created and presented to the auditee at the closing meeting.
    E. Audit objectives should be used to assess audit evidence in order to generate audit conclusions. Then, the audit findings should be created and presented to the audit client at the closing meeting.
    F. Audit objectives should be used to assess objective evidence in order to generate audit conclusions. Then, the audit recommendations should be created and presented to top management at management review.

  • Question 86:

    Scenario 3: NightCore is a multinational technology company based in the United States that focuses on e- commerce, cloud computing, digital streaming, and artificial intelligence. After having an information security management system (ISMS) implemented for over 8 months, they contracted a certification body to conduct a third party audit in order to get certified against ISO/IEC 27001.

    The certification body set up a team of seven auditors. Jack, the most experienced auditor, was assigned as the audit team leader. Over the years, he received many well known certifications, such as the ISO/IEC 27001 Lead Auditor, CISA, CISSP, and CISM.

    Jack conducted thorough analyses on each phase of the ISMS audit, by studying and evaluating every information security requirement and control that was implemented by NightCore. During stage 2 audit. Jack detected several nonconformities. After comparing the number of purchased invoices for software licenses with the software inventory, Jack found out that the company has been using the illegal versions of a software for many computers. He decided to ask for an explanation from the top management about this nonconformity and see whether they were aware about this. His next step was to audit NightCore's IT Department. The top management assigned Tom, NightCore's system administrator, to act as a guide and accompany Jack and the audit team toward the inner workings of their system and their digital assets infrastructure.

    While interviewing a member of the Department of Finance, the auditors discovered that the company had recently made some unusual large transactions to one of their consultants. After gathering all the necessary details regarding the transactions. Jack decided to directly interview the top management.

    When discussing about the first nonconformity, the top management told Jack that they willingly decided to use a copied software over the original one since it was cheaper. Jack explained to the top management of NightCore that using illegal versions of software is against the requirements of ISO/IEC 27001 and the national laws and regulations. However, they seemed to be fine with it.

    Several months after the audit, Jack sold some of NightCore's information that he collected during the audit for a huge amount of money to competitors of NightCore.

    Based on this scenario, answer the following question:

    Does ISO/IEC 27001 require organizations to comply with national laws and regulations?

    A. Yes, but relevant legal and contractual requirements do not need to be explicitly identified
    B. No, there is no clear indication in the standard as to whether the organization should comply with the national laws and regulations
    C. Yes, complying with the applicable legislation is a requirement of ISO/IEC 27001

  • Question 87:

    Scenario 7: Lawsy is a leading law firm with offices in New Jersey and New York City. It has over 50 attorneys offering sophisticated legal services to clients in business and commercial law, intellectual property, banking, and financial

    services. They believe they have a comfortable position in the market thanks to their commitment to implement information security best practices and remain up to date with technological developments.

    Lawsy has implemented, evaluated, and conducted internal audits for an ISMS rigorously for two years now. Now, they have applied for ISO/IEC 27001 certification to ISMA, a well-known and trusted certification body.

    During stage 1 audit, the audit team reviewed all the ISMS documents created during the implementation. They also reviewed and evaluated the records from management reviews and internal audits.

    Lawsy submitted records of evidence that corrective actions on nonconformities were performed when necessary, so the audit team interviewed the internal auditor. The interview validated the adequacy and frequency of the internal audits by

    providing detailed insight into the internal audit plan and procedures.

    The audit team continued with the verification of strategic documents, including the information security policy and risk evaluation criteria. During the information security policy review, the team noticed inconsistencies between the

    documented information describing governance framework (i.e., the information security policy) and the procedures.

    Although the employees were allowed to take the laptops outside the workplace, Lawsy did not have procedures in place regarding the use of laptops in such cases. The policy only provided general information about the use of laptops. The

    company relied on employees' common knowledge to protect the confidentiality and integrity of information stored in the laptops. This issue was documented in the stage 1 audit report.

    Upon completing stage 1 audit, the audit team leader prepared the audit plan, which addressed the audit objectives, scope, criteria, and procedures.

    During stage 2 audit, the audit team interviewed the information security manager, who drafted the information security policy. He justified the Issue identified in stage 1 by stating that Lawsy conducts mandatory information security training

    and awareness sessions every three months.

    Following the interview, the audit team examined 15 employee training records (out of 50) and concluded that Lawsy meets requirements of ISO/IEC 27001 related to training and awareness. To support this conclusion, they photocopied the

    examined employee training records.

    Based on the scenario above, answer the following question:

    Based on scenario 7, what should Lawsy do prior to the initiation of stage 2 audit?
