PECB ISO-IEC-27001-Lead-Auditor Exam With Confidence Using Practice Dumps

Scenario 5

CyberShielding Systems Inc. provides security services spanning the entire information technology infrastructure. It provides cybersecurity software, including endpoint security, firewalls, and antivirus software. CyberShielding Systems Inc. has helped various companies secure their networks for two decades through advanced products and services. Having achieved a reputation in the information and network security sector, CyberShielding Systems Inc. decided to implement a security information management system (ISMS) based on ISO/IEC 27001 and obtain a certification to better secure its internal and customer assets and gain a competitive advantage.

The certification body initiated the process by selecting the audit team for CyberShielding Systems Inc.'s ISO/IEC 27001 certification. They provided the company with the name and background information of each audit member. However, upon review, CyberShielding Systems Inc. discovered that one of the auditors did not hold the security clearance required by them. Consequently, the company objected to the appointment of this auditor. Upon review, the certification body replaced the auditor in response to CyberShielding Systems Inc.'s objection.

As part of the audit process, CyberShielding Systems Inc.'s approach to risk and opportunity determination was assessed as a standalone activity. This involved examining the organization’s methods for identifying and managing risks and opportunities. The audit team’s core objectives encompassed providing assurance on the effectiveness of CyberShielding Systems Inc.'s risk and opportunity identification mechanisms and reviewing the organization's strategies for addressing these determined risks and opportunities. During this, the audit team also identified a risk due to a lack of oversight in the firewall configuration review process, where changes were implemented without proper approval, potentially exposing the company to vulnerabilities. This finding highlighted the need for stronger internal controls to prevent such issues.

The audit team accessed process descriptions and organizational charts to understand the main business processes and controls. They performed a limited analysis of the IT risks and controls because their access to the IT infrastructure and applications was limited by third-party service provider restrictions. However, the audit team stated that the risk of a significant defect occurring in CyberShielding’s ISMS was low since most of the company's processes were automated. They therefore evaluated that the ISMS, as a whole, conforms to the standard requirements by questioning CyberShielding representatives on IT responsibilities, control effectiveness, and anti-malware measures. CyberShielding’s representatives provided sufficient and appropriate evidence to address all these questions.

Despite the agreement signed before the audit, which outlined the audit scope, criteria, and objectives, the audit was primarily focused on assessing conformity with established criteria and ensuring compliance with statutory and regulatory requirements.

Question

What kind of audit risk did the audit team identify? Refer to Scenario 5.

You are performing an ISMS audit at a residential nursing home called ABC that provides healthcare services.

The next step in your audit plan is to verify the information security on ABC's healthcare mobile app

development, support, and lifecycle process. During the audit, you learned the organization outsourced the

mobile app development to a professional software development company with CMMI Level 5, ITSM (ISO/IEC

20000-1), BCMS (ISO 22301) and ISMS (ISO/IEC 27001) certified. The IT Manager presented the software

security management procedure and summarised the process as follows:

The mobile app development shall adopt "security-by-design" and "security-by-default" principles, as a

minimum. The following security functions for personal data protection shall be available:

Access control.

Personal data encryption, i.e., Advanced Encryption Standard (AES) algorithm, key lengths: 256 bits; and

Personal data pseudonymization.

Vulnerability checked and no security backdoor

You sample the latest Mobile App Test report - details as follows:

You ask the IT Manager why the organisation still uses the mobile app while personal data

encryption and pseudonymization tests failed. Also, whether the Service Manager is authorized to

approve the test.

The IT Manager explains the test results should be approved by him according to the software

security management procedure. The reason why the encryption and pseudonymization functions

failed is that these functions heavily slowed down the system and service performance. An extra

150% of resources are needed to cover this. The Service Manager agreed that access control is

good enough and acceptable. That's why the Service Manager signed the approval.

You sample one of the medical staff's mobile and found that ABC's healthcare mobile app, version

1.01 is installed. You found that version 1.01 has no test record.

The IT Manager explains that because of frequent ransomware attacks, the outsourced mobile app

development company gave a free minor update on the tested software, performed an emergency

release of the updated software, and gave a verbal guarantee that there will be no impact on any

security functions. Based on his 20 years of information security experience, there is no need to re-

test.
