PECB Updated ISO-IEC-27001-Lead-Implementer Exam Questions and Answers by frances

An organization that is implementing the ISMS based on ISO/IEC 27001 has defined and communicated secure system architecture and engineering principles. However, there is no documented information related to these principles. Is this acceptable?

Scenario 7: 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 for developing and implementing a plan for treating information security risks and documenting the risk treatment results.

Furthermore, while implementing the communication plan for information security, 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.

Based on this scenario, answer the following question:

Does InfoSec adhere to the requirements of ISO/IEC 27001 when conducting information security risk assessments?

What service did Auto Tsaab implement to manage and protect information effectively?

Scenario 3: Socket Inc is a telecommunications company offering mainly wireless products and services. It uses MongoDB. a document model database that offers high availability, scalability, and flexibility.

Last month, Socket Inc. reported an information security incident. A group of hackers compromised its MongoDB database, because the database administrators did not change its default settings, leaving it without a password and publicly accessible.

Fortunately. Socket Inc. performed regular information backups in their MongoDB database, so no information was lost during the incident. In addition, a syslog server allowed Socket Inc. to centralize all logs in one server. The company found out that no persistent backdoor was placed and that the attack was not initiated from an employee inside the company by reviewing the event logs that record user faults and exceptions.

To prevent similar incidents in the future, Socket Inc. decided to use an access control system that grants access to authorized personnel only. The company also implemented a control in order to define and implement rules for the effective use of cryptography, including cryptographic key management, to protect the database from unauthorized access The implementation was based on all relevant agreements, legislation, and regulations, and the information classification scheme. To improve security and reduce the administrative efforts, network segregation using VPNs was proposed.

Lastly, Socket Inc. implemented a new system to maintain, collect, and analyze information related to information security threats, and integrate information security into project management.

Socket Inc. has implemented a control for the effective use of cryptography and cryptographic key management. Is this compliant with ISO/IEC 27001' Refer to scenario 3.
