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.
