Scenario 4: TradeB is a newly established commercial bank located in Europe, with a diverse clientele. It provides services that encompass 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, TradeB has initiated the implementation of an information security management system (ISMS) based on ISO/IEC27001. 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 the experts, TradeB opted for a methodological framework, which serves as a structured framework and a guideline that outlines the high-level stages of the ISMS implementation, the associated activities, and the deliverables without incorporating any specific tools.

The experts analyzed the ISO/IEC 27001 controls and listed only the security controls deemed applicable to the company and its 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 a methodical approach that involved defining and characterizing the terms and criteria used in the assessment process, categorizing them into non-numerical 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.

Then, they evaluated the risks based on the risk evaluation criteria, where they decided to treat only the risks of the high-risk category. Additionally, they focused primarily on the 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.

Based on the scenario above, answer the following question:

Based on scenario 4, from which source did TradeB's ISMS implementation draw its methodological framework?

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 5: Operaze is a small software development company that develops applications for various companies around the world. Recently, the company conducted a risk assessment to assess theinformation security risks that could arise from operating in a digital landscape. Using different testing methods, including penetration Resting and code review, the company identified some issues in its ICT systems, including improper user permissions, misconfigured security settings, and insecure network configurations. To resolve these issues and enhance information security, Operaze decided to implement an information security management system (ISMS) based on ISO/IEC 27001.

Considering that Operaze is a small company, the entire IT team was involved in the ISMS implementation project. Initially, the company analyzed the business requirements and the internal and external environment, identified its key processes and activities, and identified and analyzed the interested parties In addition, the top management of Operaze decided to Include most of the company's departments within the ISMS scope. The defined scope included the organizational and physical boundaries. The IT team drafted an information security policy and communicated it to all relevant interested parties In addition, other specific policies were developed to elaborate on security issues and the roles and responsibilities were assigned to all interested parties.

Following that, the HR manager claimed that the paperwork created by ISMS does not justify its value and the implementation of the ISMS should be canceled However, the top management determined that this claim was invalid and organized an awareness session to explain the benefits of the ISMS to all interested parties.

Operaze decided to migrate Its physical servers to their virtual servers on third-party infrastructure. The new cloud computing solution brought additional changes to the company Operaze's top management, on the other hand, aimed to not only implement an effective ISMS but also ensure the smooth running of the ISMS operations. In this situation, Operaze's top management concluded that the services of external experts were required to implement their information security strategies. The IT team, on the other hand, decided to initiate a change in the ISMS scope and implemented the required modifications to the processes of the company.

What is the next step that Operaze's ISMS implementation team should take after drafting the information security policy? Refer to scenario 5.

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 5: OperazelT is a software development company that develops applications for various companies worldwide. Recently, the company conducted a risk assessment in response to the evolving digital landscape and emerging information security challenges. Through rigorous testing techniques like penetration testing and code review, the company identified issues in its IT systems, including improper user permissions, misconfigured security settings, and insecure network configurations. To resolve these issues and enhance information security, OperazelT implemented an information security managementsystem (ISMS) based on ISO/IEC 27001.

In a collaborative effort involving the implementation team, OperazelT thoroughly assessed its business requirements and internal and external environment, identified its key processes and activities, and identified and analyzed the interested parties to establish the preliminary scope of the ISMS. Following this, the implementation team conducted a comprehensive review of the company's functional units, opting to include most of the company departments within the ISMS scope. Additionally, the team decided to include internal and external physical locations, both external and internal issues referred to in clause 4.1, the requirements in clause 4.2, and the interfaces and dependencies between activities performed by the company. The IT manager had a pivotal role in approving the final scope, reflecting OperazelT’s commitment to information security.

OperazelT's information security team created a comprehensive information security policy that aligned with the company's strategic direction and legal requirements, informed by risk assessment findings and business strategies. This policy, alongside specific policies detailing security issues and assigning roles and responsibilities, was communicated internally and shared with external parties. The drafting, review, and approval of these policies involved active participation from top management, ensuring a robust framework for safeguarding information across all interested parties.

As OperazelT moved forward, the company entered the policy implementation phase, with a detailed plan encompassing security definition, role assignments, and training sessions. Lastly, the policy monitoring and maintenance phase was conducted, where monitoring mechanisms were established to ensure the company's information security policy is enforced and all employees comply with its requirements.

To further strengthen its information security framework, OperazelT initiated a comprehensive gap analysis as part of the ISMS implementation process. Rather than relying solely on internal assessments, OperazelT decided to involve the services of external consultants to assess the state of its ISMS. The company collaborated with external consultants, which brought a fresh perspective and valuable insights to the gap analysis process, enabling OperazelT to identify vulnerabilities and areas for improvement with a higher degree of objectivity. Lastly, OperazelT created a committee whose mission includes ensuring the proper operation of the ISMS, overseeing the company's risk assessment process, managing information security-related issues, recommending solutions to nonconformities, and monitoring the implementation of corrections and corrective actions.

Based on the scenario above, answer the following question:

Was there any issue with how OperazelT determined its current ISMS state?

Based on ISO/IEC 27001, what areas within the organization require establishing rules, procedures, and agreements for information transfer?

Scenario 7: Incident Response at Texas H&H Inc.

Once they made sure that the attackers do not have access in their system, the security administrators decided to proceed with the forensic analysis. They concluded that their access security system was notdesigned tor threat detection, including the detection of malicious files which could be the cause of possible future attacks.

Based on these findings. Texas H$H inc, decided to modify its access security system to avoid future incidents and integrate an incident management policy in their Information security policy that could serve as guidance for employees on how to respond to similar incidents.

Based on the scenario above, answer the following question:

Based on scenario 7. what else should Texas H&H Inc. do when responding to the incident?

According to ISO/IEC 270G1. why shall organizations document nonconformities?
