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?
Refer to Scenario 4 (FinSecure)
Finsecure is a financial institution based in Finland, providing services to a diverse clientele, encompassing retail banking, corporate banking, wealth management, and digital banking, all tailored to meet the evolving financial needs of individuals and businesses in the region. Recognizing the critical importance of information security in the modern banking landscape, FinSecure has initiated the implementation of an information security management system (ISMS) based on ISO/IEC 27001. To ensure the successful implementation of the ISMS, the top management decided to contract two experts to lead and oversee the ISMS implementation project.
As a primary strategy for implementing the ISMS, the experts chose an approach that emphasizes a swift implementation of the ISMS by initially meeting the minimum requirements of ISO/IEC 27001, followed by continual improvement over time. Additionally, under the guidance of experts, FinSecure opted for a methodological framework, which serves as a structured framework that outlines the high-level stages of the ISMS implementation, the associated activities, and the deliverables without incorporating any specific tools.
The experts conducted a risk assessment, identifying all the supporting assets, which were the most tangible ones. They assessed the potential consequences and likelihood of various risks, determining the level of risks using a methodical approach that involved defining and characterizing the terms and criteria used in the assessment process. These risks were categorized into nonnumerical levels (e g., very low, low. moderate, high, very high). Explanatory notes were thoughtfully crafted to justify assessed values, with the primary goal of enhancing repeatability and reproducibility.
After completing the risk assessment, the experts reviewed a selected number of the security controls from Annex A of ISO/IEC 27001 to determine which ones were applicable to the company's specific context. The decision to implement security controls was justified by the risk assessment results. Based on this review, they drafted the Statement of Applicability (SoA). They focused on treating only the high-risk category particularly addressing unauthorized use of administrator rights and system interruptions due to several hardware failures. To address these issues, they established a new version of the access control policy, implemented controls to manage and control user access, and introduced a control for ICT readiness to ensure business continuity.
Their risk assessment report indicated that if the implemented security controls reduce the risk levels to an acceptable threshold, those risks will be accepted
Question:
Did the experts draft the Statement of Applicability (SoA) in accordance with ISO/IEC 27001?
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?
