Executive Summary

Bluesky Systems faces significant challenges with its current outdated infrastructure, characterized by legacy Windows Server 2003 systems, security vulnerabilities, inefficient disaster recovery processes, and non-compliance with government security standards. These issues have led to repeated outages, potential security breaches, and compromised data integrity, which threaten their reputation and operational stability, especially with the impending addition of a remote site in Sierra Vista.

My proposed deployment introduces a strategic upgrade to Windows Server 2008 (specifically Windows Server 2008 R2) at all sites, complemented by a robust Active Directory hierarchy, enhanced security policies, and reliable data management systems. By replacing or upgrading existing servers, implementing centralized management via Windows Server features, and establishing secure remote access solutions such as VPNs with certificate-based authentication, this plan will significantly improve system performance, security posture, and business continuity. Additionally, the deployment of DHCP, DNS, WSUS, backup, and monitoring services will streamline operations, enhance security, and facilitate scalable infrastructure growth.

This comprehensive approach ensures Bluesky transitions smoothly from their current aging infrastructure to a modern, secure, and compliant environment. The plan promotes resilience through redundancy, high-availability configurations, and disaster recovery strategies aligned with government standards, thereby increasing operational uptime and safeguarding sensitive data. Choosing this deployment plan will position Bluesky as a compliant and secure organization capable of supporting their expanding military and commercial contracts seamlessly. This strategic upgrade will provide long-term benefits, including operational efficiency, enhanced security, and compliance, making it the optimal choice over competitors' proposals.

Network Infrastructure Design

The current network infrastructure comprises three sites—Tucson, Phoenix, and Sierra Vista—connected through VPNs via Cisco ASA firewalls. The existing configuration includes a single forest with a domain named bluesky.local. Within this forest, there are two domain controllers at Tucson, one at Phoenix, and plans to add another at Sierra Vista. The organizational structure employs a default organizational unit (OU) setup, though this can be optimized to support administrative delegation and security policies more effectively.

In my design, I propose restructuring the AD forest into a single, unified forest with a hierarchical domain structure to facilitate scalability and administrative efficiency. A primary domain named bluesky.local will be established with child OUs for each site—Tucson, Phoenix, and Sierra Vista. Each site will host multiple domain controllers configured for high availability, ensuring continuous AD services even in failure scenarios. Trust relationships will be established as needed, but a single forest simplifies management and aligns with the company's growth plans.

The network topology will feature dedicated site links with scheduled replication, optimized based on bandwidth and latency. Each site's DNS namespace will be integrated with Active Directory to support seamless name resolution and service location. A detailed diagram illustrating the hierarchical structure, including the forest, domain, and OU arrangements, would clarify this design.

IP Addressing and DHCP Configuration

For efficient and manageable IP address allocation, a DHCP infrastructure will be deployed across all sites, with dedicated DHCP servers hosting the primary scope for each location. The existing IP scheme, based on the 192.168.x.x subnet, will be extended and organized for clarity and scalability.

The Tucson site’s DHCP server will host multiple scopes: one for servers and network infrastructure devices, and another for client workstations. For example, the server subnet might be 192.168.1.1 – 192.168.1.127, and the client subnet 192.168.1.128 – 192.168.1.254. The Phoenix and Sierra Vista sites will follow similar schemes, with non-overlapping address blocks for simplicity. Reservations will be used for critical servers and network devices to ensure consistent address assignments.

DHCP options will include default gateways, DNS servers (primary and secondary), WINS (if needed), and domain name settings. Relay agents will be configured on routers connecting non-DHCP-enabled segments, ensuring DHCP communication across routed networks. Dynamic leases will be set for 8 days, with reservations for essential infrastructure components to ensure stability during outages.

DNS Namespace Structure

The DNS namespace will mirror the AD structure to facilitate seamless service discovery and name resolution. The primary zone, bluesky.local, will be hosted on BlueskyDNS1 at Tucson, with secondary zone replication on BlueskyDNS2. External name resolution will be facilitated via a public DNS zone, such as bluesky.com, managed through appropriate external DNS providers or internal DNS servers with forwarder configurations.

The internal DNS namespace will feature host records for servers, including BlueskyDNS1, BlueskyDNS2, BlueskyData, BlueskyPhoenix, and the upcoming Sierra Vista server, enabling efficient resource location. The structure will follow a hierarchical format: servername.bluesky.local. This setup allows simple, consistent name resolution both internally and externally with redundancy and security.

Security and Disaster Recovery Features

To ensure security, all DNS servers and domain controllers will utilize secure DNS peer zones with zone transfer restrictions. Active Directory integrated DNS zones will support dynamic updates secured via permissions and encryption. Firewall rules and VPN configurations will enforce encryption and authentication for remote access, with certificate-based VPN authentication coupled with strong policies.

All sites will deploy Windows Server 2008 R2 domain controllers, which support advanced security features such as fine-grained password policies, read-only domain controllers (RODCs) for remote sites, and enhanced Group Policy management.

Business continuity is addressed through a comprehensive backup plan that includes daily backups of critical servers, off-site storage, and a disaster recovery site plan. Regular testing of restore procedures and documentation will ensure preparedness. Server virtualization using Hyper-V will be leveraged to facilitate rapid provisioning and recovery of services.

Remote Access and Secure Connectivity

Remote access will employ a VPN solution using Cisco ASA firewalls with certificate-based authentication, multi-factor authentication, and Network Policy Server (NPS) for policy enforcement. This setup ensures only authorized personnel connect securely, maintaining compliance and security standards.

Implementation of DirectAccess or Always On VPN features (if compatible with Windows Server 2008 R2) will enhance remote connectivity by providing seamless, secure access without traditional VPN client configurations, reducing user complexity while maintaining security compliance.

Application and Data Provisioning

All servers will host necessary business applications and shared data stores, with centralized management via Active Directory and Group Policy. Shared folders and print services will be duplicated across multiple servers to ensure availability and load balancing, especially for executive and department-specific resources.

All client workstations will be upgraded to Windows 7, featuring standardized images to streamline deployment, updates, and management through Windows Deployment Services (WDS) and System Center Configuration Manager (SCCM). This approach allows easy software updates, security patches, and configuration management, reducing administrative overhead and ensuring compliance.

Monitoring and Management

Proactive monitoring tools such as System Center Operations Manager (SCOM), along with Windows Server performance counters and logging, will be implemented to monitor health, performance, and security events. Alerts will trigger automated responses or notifications, enabling rapid incident response.

Security policies, auditing, and compliance controls will be implemented via Group Policy and security baseline configurations. All activities, including logon, changes, and access attempts, will be logged and reviewed periodically to detect anomalies and maintain security.

Conclusion

This deployment plan offers a comprehensive, secure, and scalable solution that modernizes Bluesky Systems' infrastructure, ensuring high availability, robustness, and compliance. By upgrading to Windows Server 2008 R2, deploying critical services, enforcing security policies, and providing reliable remote access, Bluesky will be well-positioned to support current and future operational demands while safeguarding their data assets and maintaining compliance with government standards.
