Your Consulting Company Has Been Hired To Design And Implement A Netwo

Your consulting company has been hired to design and implement a network for a small to mid-sized vertically integrated sales and manufacturing company with about 75 employees and 40 PCs. They have provided the following requirements:

  • Develop a central Domain Structure including the design of Organizational Units (OUs) based on the company's organizational chart for efficient management of workstations and users.
  • Configure Group Policies to support:
    • Encryption of files on client machines with appropriate recovery options.
    • Setup shared file locations with permissions based on Active Directory (AD) structure, ensuring departmental shares are accessible only to designated users.
  • Configure a central update server with appropriate group targeting to automate and control client updates.
  • Implement Roaming Profiles for users along with folder redirection for critical folders—Documents, Desktop, and Favorites—to improve login performance and security. Proper security settings must prevent unauthorized access to profiles and redirected folders.
  • Configure DNS services as necessary within the environment to support network resolutions.
  • Develop a plan (not implementation) for future Dynamic Host Configuration Protocol (DHCP) configuration.
  • Setup and configure a print server to share printers with permissions that control access, especially for the color printer, ensuring that the CEO’s printing needs are prioritized and access control is enforced.
  • Include a recommended backup and recovery plan; implementation is not required.
  • Design a secure solution for remote access allowing employees to access applications from personal devices or while traveling with work devices.

For the final deliverables, detailed documentation of the proof of concept environment and configurations must be provided. This documentation should be comprehensive enough for replication and explain the rationale behind each configuration choice. Additionally, a business-oriented video presentation (5 to 10 minutes) should be prepared, using visual aids and non-technical language to explain how the requirements were addressed, including background assumptions even if they are not explicitly part of the requirements.

Paper For Above instruction

The design and implementation of a network for a small to mid-sized company requires meticulous planning, a clear understanding of organizational needs, and strategic deployment of technological solutions. In this paper, I will outline a comprehensive plan and justification for each aspect of the proposed network architecture, aligning with the client's specifications to ensure operational efficiency, security, and future scalability.

Domain Structure and Organizational Units

At the core of the network design is the creation of a centralized Active Directory (AD) domain that reflects the company's organizational hierarchy through the use of Organizational Units (OUs). The structure will include top-level OUs for management, sales, manufacturing, and administration, with nested OUs for workstations and users within each department. This hierarchy facilitates targeted group policies and streamlined management. For example, the 'Sales' OU could contain all sales department workstations and user accounts, with policies tailored exclusively to their operational needs, such as access restrictions and specific software deployment.

Group Policies Configuration

Group Policies (GPOs) are vital for enforcing security, configuration management, and operational consistency. Policies will be developed to require encryption of files stored on client devices using BitLocker or a similar encryption solution, with recovery keys stored securely in Active Directory. This ensures data confidentiality and recoverability in case of device loss or failure. Additionally, GPOs will configure Windows Update settings to connect client machines to a central update server, using client-side targeting to assign groups to appropriate update schedules and patches, reducing vulnerabilities and ensuring compliance.

Shared File Storage and Permissions

Shared folders will be created for each department, with access permissions strictly limited to respective departmental users. Permissions will be managed through AD groups to simplify administration and enforce access controls. For example, the sales share will only allow users in the Sales AD group to read/write, preventing unauthorized access from other departments. The shares will be hosted on the centralized server with NTFS permissions aligned with share permissions for security and ease of management.

DNS and Future DHCP Planning

DNS services will be configured to ensure reliable name resolution within the network. The DNS zone structure will be straightforward, supporting internal hostname resolution. Although DHCP is not yet to be implemented, a detailed planning document will outline scope, IP address ranges, reservation strategies, and future integration of DHCP for dynamic IP address management, allowing smooth network expansion.

Update Server and Client Management

A WSUS (Windows Server Update Services) server will serve as the central update point, assigning targeted groups through GPOs to ensure that all clients receive appropriate security patches and software updates promptly. Client-side targeting allows specific deployment of updates based on departmental or role-based grouping, minimizing disruption and maintaining security compliance.

Roaming Profiles and Folder Redirection

Roaming profiles will be configured for all user accounts to facilitate a seamless user experience across multiple devices. Folder redirection policies will redirect key folders—Documents, Desktop, and Favorites—to network locations, reducing login times and protecting user data. Security permissions are crucial to prevent other users from accessing others’ profiles; therefore, proper NTFS permissions will be enforced. These configurations improve productivity and data security by enabling users to access personalized settings regardless of the device used, while ensuring privacy.

Print Server Setup

The print server will manage all shared printers, with permissions assigned based on user roles. The CEO's requirements for prioritized printing will be addressed by configuring print queues and permissions such that the CEO's print jobs are handled with high priority, possibly by assigning higher priority options or dedicated queues. To control who can print to the color printer, access permissions will be restricted through AD security groups, ensuring only authorized users can print color documents, thereby controlling resource usage and costs.

Remote Access Solutions

A secure remote access solution, such as VPN combined with multi-factor authentication, will be implemented to enable employees to connect securely to the company's network from personal devices or when traveling. This method protects sensitive data during transmission and ensures only authorized users can access internal resources. The solution will include endpoint security policies and encryption to safeguard data integrity and confidentiality.

Backup and Recovery Planning

A comprehensive backup and recovery plan will be recommended, incorporating regular backups of critical data, server configurations, and system images. Offsite storage solutions and cloud backup options will be considered to mitigate risks like physical damage or cyberattacks. Disaster recovery procedures will be documented to ensure business continuity in the event of data loss or system failure.

Conclusion

The proposed network infrastructure balances security, efficiency, scalability, and manageability. Each component, from AD structure to remote access, has been designed with both current requirements and future growth in mind. The detailed documentation and strategic planning outlined here serve as a foundation for successful deployment, ensuring the client’s operational needs are met while maintaining a high standard of security and ease of management.
