Scenario 28: InfoSec based in Boston, MA, is a multinational corporation offering professional electronics, gaming, and entertainment products. Following several information security incidents, InfoSec has decided to establish teams of experts and implement measures to prevent potential incidents in the future.
Emma, Bob, and Anna were hired as the new members of InfoSec’s information security team, which consists of a security architecture team, an incident response team (IRT), and a forensics team. Emma’s job is to create information security plans, policies, protocols, and training to prepare InfoSec to respond to incidents effectively. Emma and Bob would be full-time employees of InfoSec, whereas Anna was contracted as an external consultant.
Bob, a network expert, will implement a screened subnet network architecture. This architecture will isolate the demilitarized zone (DMZ) to which hosted public services are attached and InfoSec’s publicly accessible resources from their private network. Thus, InfoSec will be able to block potential attackers from causing unwanted events inside the company’s network. Bob is also responsible for ensuring a thorough evaluation of the nature of an unexpected event, including how the event happened and what or whom it might affect.
On the other hand, Anna will create records of the data, reviews, analyses, and reports to keep evidence for disciplinary and legal action and use them to prevent future incidents. To do the work accordingly, she should be aware of the company’s information security incident management policy beforehand. Among others, this policy specifies the type of records to be created, the place where they should be kept, and the format and content that specific record types should have.
As part of InfoSec’s initiative to strengthen information security measures, Anna will conduct information security risk assessments only when significant changes are proposed and will document the results of these risk assessments. Upon completion of the risk assessment process, Anna is responsible to develop and implement a plan for treating information security risks and document the risk treatment results.
Furthermore, while implementing the communication plan for information security, the InfoSec’s top management was responsible for creating a roadmap for new product development. This approach helps the company to align its security measures with the product development efforts, demonstrating a commitment to integrating security into every aspect of its business operations.
InfoSec uses a cloud service model that includes cloud-based apps accessed through the web or an application programming interface (API). All cloud services are provided by the cloud service provider, while data is managed by InfoSec. This introduces unique security considerations and becomes a primary focus for the information security team to ensure data and systems are protected in this environment.
Was the decision to hire Anna as an external consultant in scenario 28 aligned with the requirements of ISO/IEC 27001?
- No, the skills of incident response or forensic analysis shall be developed internally
- Yes, forensic investigation may be conducted internally or by using external consultants
- Yes, organizations must use external consultants for forensic investigation, as required by the standard
Answer(s): B
Explanation:
According to ISO/IEC 27001, the standard allows organizations to conduct forensic investigations either internally (using their own employees) or externally (by hiring external consultants) based on the organization's needs and resources. It does not mandate that forensic investigations must be conducted only by internal employees or external consultants.
Anna, who is hired as an external consultant, is tasked with conducting forensic analysis and creating documentation for potential disciplinary and legal action. This decision aligns with the flexibility provided by ISO/IEC 27001, allowing external consultants to be involved in these processes.
