Scenario 9:

OpenTech, headquartered in San Francisco, specializes in information and communication technology (ICT) solutions. Its clientele primarily includes data communication enterprises and network operators. The company's core objective is to enable its clients to transition smoothly into multi-service providers, aligning their operations with the complex demands of the digital landscape.

Recently, Tim, the internal auditor of OpenTech, conducted an internal audit that uncovered nonconformities related to their monitoring procedures and system vulnerabilities. In response to these nonconformities, OpenTech decided to employ a comprehensive problem-solving approach to address the issues systematically. This method encompasses a team-oriented approach, aiming to identify, correct, and eliminate the root causes of the issues. The approach involves several steps: First, establish a group of experts with deep knowledge of processes and controls. Next, break down the nonconformity into measurable components and implement interim containment measures. Then, identify potential root causes and select and verify permanent corrective actions. Finally, put those actions into practice, validate them, take steps to prevent recurrence, and recognize and acknowledge the team's efforts.

Following the analysis of the root causes of the nonconformities, OpenTech's ISMS project manager, Julia, developed a list of potential actions to address the identified nonconformities. Julia carefully evaluated the list to ensure that each action would effectively eliminate the root cause of the respective nonconformity. While assessing potential corrective actions, Julia identified one issue as significant and assessed a high likelihood of its recurrence. Consequently, she chose to implement temporary corrective actions. Julia then combined all the nonconformities into a single action plan and sought approval from top management. The submitted action plan was written as follows:

"A new version of the access control policy will be established and new restrictions will be created to ensure that network access is effectively managed and monitored by the Information and Communication Technology (ICT) Department."

However, Julia's submitted action plan was not approved by top management. The reason cited was that a general action plan meant to address all nonconformities was deemed unacceptable. Consequently, Julia revised the action plan and submitted separate ones for approval. Unfortunately, Julia did not adhere to the organization's specified deadline for submission, resulting in a delay in the corrective action process. Additionally, the revised action plans lacked a defined schedule for execution.

Did OpenTech have a plan in place to implement permanent corrective action to address the identified nonconformities?

Scenario 3: Socket Inc is a telecommunications company offering mainly wireless products and services. It uses MongoDB. a document model database that offers high availability, scalability, and flexibility.

Last month, Socket Inc. reported an information security incident. A group of hackers compromised its MongoDB database, because the database administrators did not change its default settings, leaving it without a password and publicly accessible.

Fortunately. Socket Inc. performed regular information backups in their MongoDB database, so no information was lost during the incident. In addition, a syslog server allowed Socket Inc. to centralize all logs in one server. The company found out that no persistent backdoor was placed and that the attack was not initiated from an employee inside the company by reviewing the event logs that record user faults and exceptions.

To prevent similar incidents in the future, Socket Inc. decided to use an access control system that grants access to authorized personnel only. The company also implemented a control in order to define and implement rules for the effective use of cryptography, including cryptographic key management, to protect the database from unauthorized access The implementation was based on all relevant agreements, legislation, and regulations, and the information classification scheme. To improve security and reduce the administrative efforts, network segregation using VPNs was proposed.

Lastly, Socket Inc. implemented a new system to maintain, collect, and analyze information related to information security threats, and integrate information security into project management.

Based on scenario 3, what would help Socket Inc. address similar information security incidents in the future?

Scenario 4: TradeB. a commercial bank that has just entered the market, accepts deposits from its clients and offers basic financial services and loans for investments. TradeB has decided to implement an information security management system (ISMS) based on ISO/IEC 27001 Having no experience of a management [^system implementation, TradeB's top management contracted two experts to direct and manage the ISMS implementation project.

First, the project team analyzed the 93 controls of ISO/IEC 27001 Annex A and listed only the security controls deemed applicable to the company and their objectives Based on this analysis, they drafted the Statement of Applicability. Afterward, they conducted a risk assessment, during which they identified assets, such as hardware, software, and networks, as well as threats and vulnerabilities, assessed potential consequences and likelihood, and determined the level of risks based on three nonnumerical categories (low, medium, and high). They evaluated the risks based on the risk evaluation criteria anddecided to treat only the high risk category They also decided to focus primarily on the unauthorized use of administrator rights and system interruptions due to several hardware failures by establishing a new version of the access control policy, implementing controls to manage and control user access, and implementing a control for ICT readiness for business continuity

Lastly, they drafted a risk assessment report, in which they wrote that if after the implementation of these security controls the level of risk is below the acceptable level, the risks will be accepted

Based on scenario 4, the fact that TradeB defined the level of risk based on three nonnumerical categories indicates that;

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.

Based on scenario 1, what type of controls did HealthGenic decide to prioritize?
