Scenario 7: Webvue. headquartered in Japan, is a technology company specializing in the development, support, and maintenance of computer software. Webvue provides solutions across various technology fields and business sectors. Its flagship service is CloudWebvue, a comprehensive cloud computing platform offering storage, networking, and virtual computing services. Designed for both businesses and individual users. CloudWebvue is known for its flexibility, scalability, and reliability.
Webvue has decided to only include CloudWebvue in its ISO/IEC 27001 certification scope. Thus, the stage 1 and 2 audits were performed simultaneously Webvue takes pride in its strictness regarding asset confidentiality They protect the information stored in CloudWebvue by using appropriate cryptographic controls. Every piece of information of any classification level, whether for internal use. restricted, or confidential, is first encrypted with a unique corresponding hash and then stored in the cloud
The audit team comprised five persons Keith. Sean. Layla, Sam. and Tina. Keith, the most experienced auditor on the IT and information security auditing team, was the audit team leader. His responsibilities included planning the audit and managing the audit team. Sean and Layla were experienced in project planning, business analysis, and IT systems (hardware and application) Their tasks included audit planning according to Webvue’s internal systems and processes Sam and Tina, on the other hand, who had recently completed their education, were responsible for completing the day-to-day tasks while developing their audit skills
While verifying conformity to control 8.24 Use of cryptography of ISO/IEC 27001 Annex A through interviews with the relevant staff, the audit team found out that the cryptographic keys have been initially generated based on random bit generator (RBG) and other best practices for the generation of the cryptographic keys. After checking Webvue's cryptography policy, they concluded that the information obtained by the interviews was true. However, the cryptographic keys are still in use because the policy does not address the use and lifetime of cryptographic keys.
As later agreed upon between Webvue and the certification body, the audit team opted to conduct a virtual audit specifically focused on verifying conformity to control 8.11 Data Masking of ISO/IEC 27001 within Webvue, aligning with the certification scope and audit objectives. They examined the processes involved in protecting data within CloudWebvue. focusing on how the company adhered to its policies and regulatory standards. As part of this process. Keith, the audit team leader, took screenshot copies of relevant documents and cryptographic key management procedures to document and analyze the effectiveness of Webvue's practices.
Webvue uses generated test data for testing purposes. However, as determined by both the interview with the manager of the QA Department and the procedures used by this department, sometimes live system data are used. In such scenarios, large amounts of data are generated while producing more accurate results. The test data is protected and controlled, as verified by the simulation of the encryption process performed by Webvue's personnel during the audit
While interviewing the manager of the QA Department, Keith observed that employees in the Security Training Department were not following proper procedures, even though this department fell outside the audit scope. Despite the exclusion in the audit scope, the non conformity in the Security Training Department has potential implications for the processes within the audit scope, specifically impacting data security and cryptographic practices in CloudWebvue. Therefore, Keith incorporated this finding into the audit report and accordingly informed the auditee.
Based on the scenario above, answer the following question:
Question:
Based on Scenario 7, the audit team checked Webvue’s cryptography policy to obtain reasonable assurance of the information obtained during interviews. Which type of audit procedure has been used?
