Assignment Questions

1. For each of the seven domains of a typical IT infrastructure, describe a policy you would write and implement for each domain.
2. How does separation of duties throughout an IT infrastructure mitigate risk for an organization?
3. When using a layered security approach to system administration, who would have the highest access privileges?
4. Why do you only want to refer to technical standards in a policy definition document?
5. Explain why the seven domains of a typical IT infrastructure help organizations align to separation of duties.
6. Why is it important for an organization to have a policy definition for business continuity and disaster recovery?
7. Create a security management policy that addresses the management and the separation of duties throughout the seven domains of a typical IT infrastructure, based on the scenario for the Lone Star Credit Union/Bank. Your policy should define the information systems security responsibility for each domain and incorporate a definition for separation of duties. Use the provided template to include policy name, policy statement, purpose/objectives, scope, standards, procedures, and guidelines. Ensure the policy is concise, covering about two pages, and tailored to the organization's context, including compliance with GLBA, internet use controls, email security, and policy review processes.

The seven domains of a typical IT infrastructure—User, Workstation, LAN, WAN, Server, Data, and Applications—are fundamental to managing and securing organizational information systems. Developing tailored policies for each domain helps establish clear standards and responsibilities, ensuring comprehensive security management. Such policies address specific risks within each domain and set guidance on control mechanisms to monitor and mitigate vulnerabilities. For example, a policy for the User Domain might mandate employee security training and enforce strong password protocols. In the Workstation Domain, policies could specify software patching and anti-malware requirements. LAN policies could enforce network segmentation and access controls, while WAN policies ensure secure remote connections. Server policies might focus on configuration management and patching, Data policies on encryption and backup, and Application policies on secure coding and deployment practices. These policies collectively support organizational compliance, particularly with regulations like the Gramm-Leach-Bliley Act (GLBA), and promote a unified security posture.

Separation of duties (SoD) in IT infrastructure is a critical risk mitigation strategy. SoD divides responsibilities among multiple individuals or teams so that no single entity controls an entire process or critical task. This division helps prevent fraud, errors, and malicious activities by ensuring checks and balances. For example, one team might handle system administration while another manages audit and monitoring functions. In this way, the risk of insider threats is reduced, and the organization enhances its capacity to detect and respond to security incidents promptly. Moreover, separation of duties supports compliance requirements, demonstrating that appropriate control measures are in place to prevent conflicts of interest and unauthorized access.

In a layered security approach, the individual with the highest access privileges typically holds the role of the System or Security Administrator. This person has broad permissions necessary to configure, monitor, and secure all systems within the infrastructure. However, ideally, even these privileges are segmented based on strict policies to prevent conflicts and reduce risks. For example, administrative privileges should be closely monitored and possibly separated into roles such as network admin, database admin, and security admin, each with specific responsibilities. This hierarchy ensures critical systems are protected against both external threats and insider misuse, while the layered approach offers multiple controls at different levels, providing defense-in-depth.

Referring solely to technical standards in policy definitions is crucial because such standards provide clear, measurable, and enforceable benchmarks for technology configurations and security practices. Technical standards specify hardware requirements, software configurations, security protocols, and performance benchmarks, ensuring consistency and compliance across all organizational assets. Incorporating standards into policies ensures that security measures are aligned with industry best practices, regulatory requirements, and technological capabilities. For instance, referencing standards like ISO/IEC 27001 or NIST SP 800-53 ensures that policies adhere to globally recognized security frameworks, facilitating audits, and continuous improvement.

The seven domains of a typical IT infrastructure facilitate organizational alignment with the principle of separation of duties by delineating distinct areas of responsibility. Each domain involves specialized processes and controls, allowing organizations to assign responsibilities clearly to different personnel or teams. For example, the Data Domain handles data classification and encryption, while the Application Domain manages software deployment and security testing. By segregating duties across these domains, organizations reduce the risk of insider threats, errors, or conflicts of interest, since no single individual can control all aspects of a process. Additionally, structured responsibilities support compliance initiatives and improve incident response, as clear domains streamline monitoring and accountability.

Having a formal policy for business continuity and disaster recovery (BC/DR) is vital because it ensures organizational resilience in the face of disruptions, whether due to cyberattacks, natural disasters, or system failures. Such policies outline critical procedures for data backup, systems recovery, communication protocols, and roles during a crisis. They help minimize operational downtime, protect sensitive data, and maintain customer trust. A well-defined BC/DR policy also supports regulatory compliance, including industry standards and legal requirements. Furthermore, it fosters a culture of preparedness, ensuring employees understand their responsibilities and recovery processes. Regular testing and updates of the policy enable organizations to adapt to evolving threats and technological changes, ensuring rapid and effective responses to incidents.

The security management policy for Lone Star Credit Union must address management and separation of duties across all seven domains—User, Workstation, LAN, WAN, Server, Data, and Applications—within the organization's context. The policy defines roles, responsibilities, and controls to ensure compliance with GLBA, mitigate risks, and uphold confidentiality, integrity, and availability of financial data. It emphasizes strict access controls, content filtering, email security, and policy review practices. Responsibilities are clearly divided to prevent conflicts of interest and insider threats, with specific personnel assigned to manage each domain securely. The policy mandates regular security training, audit, and monitoring activities to ensure ongoing adherence. This structured approach promotes comprehensive security, aligns with legal and regulatory requirements, and maintains operational resilience across all organizational assets.
