Company X restricted the access of the internal auditor of some of its documentation taking into account its confidentiality. 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 comply with ISO/IEC 27001 requirements regarding the information security risk treatment plan?

Scenario 1:

HealthGenic is a leading multi-specialty healthcare organization providing patients with comprehensive medical services in Toronto, Canada. The organization relies heavily on a web-based medical software platform to monitor patient health, schedule appointments, generate customized medical reports, securely store patient data, and facilitate seamless communication among various stakeholders, including patients, physicians, and medical laboratory staff.

As the organization expanded its services and demand grew, frequent and prolonged service interruptions became more common, causing significant disruptions to patient care and administrative processes. As such, HealthGenic initiated a comprehensive risk analysis to assess the severity of risks it faced.

When comparing the risk analysis results with its risk criteria to determine whether the risk and its significance were acceptable or tolerable, HealthGenic noticed a critical gap in its capacity planning and infrastructure resilience. Recognizing the urgency of this issue, HealthGenic reached out to the software development company responsible for its platform. Utilizing its expertise in healthcare technology, data management, and compliance regulations, the software development company successfully resolved the service interruptions.

However, HealthGenic also uncovered unauthorized changes to user access controls. Consequently, some medical reports were altered, resulting in incomplete and inaccurate medical records. The company swiftly acknowledged and corrected the unintentional changes to user access controls. When analyzing the root cause of these changes, HealthGenic identified a vulnerability related to the segregation of duties within the IT department, which allowed individuals with system administration access also to manage user access controls. Therefore, HealthGenic decided to prioritize controls related to organizational structure, including segregation of duties, job rotations, job descriptions, and approval processes.

In response to the consequences of the service interruptions, the software development company revamped its infrastructure by adopting a scalable architecture hosted on a cloud platform, enabling dynamic resource allocation based on demand. Rigorous load testing and performance optimization were conducted to identify and address potential bottlenecks, ensuring the system could handle increased user loads seamlessly. Additionally, the company promptly assessed the unauthorized access and data alterations.

To ensure that all employees, including interns, are aware of the importance of data security and the proper handling of patient information, HealthGenic included controls tailored to specifically address employee training, management reviews, and internal audits. Additionally, given the sensitivity of patient data, HealthGenic implemented strict confidentiality measures, including robust authentication methods, such as multi-factor authentication.

In response to the challenges faced by HealthGenic, the organization recognized the vital importance of ensuring a secure cloud computing environment. It initiated a comprehensive self-assessment specifically tailored to evaluate and enhance the security of its cloud infrastructure and practices.

According to scenario 1, what is the possible threat associated with the vulnerability discovered by HealthGenic when analyzing the root cause of unauthorized changes?

Scenario 2: Beauty is a cosmetics company that has recently switched to an e-commerce model, leaving the traditional retail. The top management has decided to build their own custom platform in-house and outsource the payment process to an external provider operating online payments systems that support online money transfers.

Due to this transformation of the business model, a number of security controls were implemented based on the identified threats and vulnerabilities associated to critical assets. To protect customers' information. Beauty's employees had to sign a confidentiality agreement. In addition, the company reviewed all user access rights so that only authorized personnel can have access to sensitive files and drafted a new segregation of duties chart.

However, the transition was difficult for the IT team, who had to deal with a security incident not long after transitioning to the e commerce model. After investigating the incident, the team concluded that due to the out-of-date anti-malware software, an attacker gamed access to their files and exposed customers' information, including their names and home addresses.

The IT team decided to stop using the old anti-malware software and install a new one which would automatically remove malicious code in case of similar incidents. The new software was installed in every workstation within the company. After installing the new software, the team updated it with the latest malware definitions and enabled the automatic update feature to keep it up to date at all times. Additionally, they established an authentication process that requires a user identification and password when accessing sensitive information.

In addition, Beauty conducted a number of information security awareness sessions for the IT team and other employees that have access to confidential information in order to raise awareness on the importance of system and network security.

Based on scenario 2, which information security principle is the IT team aiming to ensure by establishing a user authentication process that requires user identification and password when accessing sensitive information?
