Telecommunications Network Security Case Project

Telecommunications Network Securitycase Project Network Security Pl

Telecommunications & Network Security Case Project (Network Security Plan) The Acme Corporation is a new startup that wishes to sell their new phone, called Acmephone, to the public. Acmephone plans to offer two options. 1) a secure version of the phone designed for business organizations called the Acmephone B+, and 2) a highly secure version of the phone designed for the government, called the Acmephone G+. Due to the fear of corporate espionage and government security requirements, there are many security concerns that must be addressed. As a network security professional, you have been employed to design a network infrastructure for their two campuses located in Atlanta and Cincinnati based upon the following specifications: 1. There needs to be a constant connection between the two locations that can carry at least 50 Mbps of data. 2. Each facility has three floors. The buildings are rectangular with each floor 350’x350’. 3. There will be 200 network connections on each floor with an additional 100 network connections in the data centers located on the third floor of each building. 4. The primary data center will be located at the Atlanta location. 5. There will be a failover data center at the Cincinnati location. 6. Each location should be protected from intrusions that are not limited to state change attacks. 7. The Atlanta location will house the two secure development teams. As such, it will need the a greater level of security. The primary database servers and the corporate Web servers will be housed at that location as well. 8. Database servers will also be located at the Cincinnati site as well. 9. All servers must have redundancy. 10. The solution must have a plan to verify security measures. Your job is to develop a network design to meet the requirements above.

Paper For Above instruction

The network security plan for Acme Corporation requires a comprehensive and multi-layered approach to ensure secure, reliable, and efficient communication between its two campuses in Atlanta and Cincinnati. Given the critical nature of their operations, especially with secured development teams and sensitive data centers, the design must incorporate robust infrastructure, security protocols, and redundancy mechanisms that align with industry best practices.

Network Topology and Hardware

The core of the network architecture will be a hybrid topology integrating star and meshed configurations to ensure fault tolerance and high availability. The primary link between Atlanta and Cincinnati must support at least 50 Mbps of dedicated bandwidth, utilizing MPLS VPNs or leased fiber optic circuits for secure and scalable connectivity. Each campus's building layout, covering three floors and a data center, necessitates strategic placement of core switches, distribution switches, and access points.

At each location, network devices such as Cisco Catalyst switches or Juniper EX-series switches will be employed at the wiring closets to connect 200 network connections per floor, with an additional 100 connections in the data centers. Redundant core routers and switches will be implemented to prevent single points of failure. The Atlanta data center will host primary database and web servers, with the Cincinnati site serving as a failover. Redundant servers, load balancers, and SAN storage will enhance availability and performance.

Recommended Cabling

For high-speed and reliable communication, Category 6A Ethernet cabling is recommended for the internal network, supporting up to 10 Gbps speeds suitable for enterprise environments. For backbone connections, fiber optic cabling—such as OM3 or OM4 multimode fibers—will provide necessary bandwidth and immunity to electromagnetic interference, especially between campuses and for data center interconnects.

Wiring Closets and Configuration

Multiple wiring closets will be positioned on each floor near server rooms and workstations to minimize cable length and facilitate efficient network management. Each wiring closet will contain switches with sufficient port density and redundancy capabilities. Fiber patch panels will connect these closets to the main data center, ensuring scalable and manageable cabling infrastructure. Proper cable management and environmental controls in these closets will further enhance network reliability.

Security Measures and Defense Strategies

Security solutions will include multilayered firewalls (e.g., Cisco ASA or Palo Alto Networks), intrusion detection and prevention systems (IDS/IPS), and network access controls such as 802.1X port-based authentication. Segmentation of the network into VLANs will isolate sensitive development and data center networks from user segments to reduce attack surface.

Stateful firewalls and next-generation firewalls will monitor traffic for anomalies and block malicious activities. Regular vulnerability assessments, penetration testing, and security audits will verify the effectiveness of these measures. Additionally, implementing VPNs with strong encryption (e.g., AES-256) will secure remote and inter-site communications.

Attack Prevention and Traps

Deploying honeypots and network traps can detect and divert attacks, gaining intelligence on malicious behaviors. Intrusion detection systems (IDS) like Snort or Suricata will monitor network traffic for known threat signatures. Also, automated alerts for unusual activity, coupled with intrusion prevention systems (IPS), will proactively block attack vectors.

WAN Connection Recommendations

Dedicated leased lines or MPLS VPNs provide secure, high-bandwidth interconnectivity. Redundant WAN pathways should be established with diverse routing to prevent disconnection from outages or disruptions. Utilizing SD-WAN technology can enhance traffic management and security across multiple WAN links, ensuring optimal performance and failover capabilities.

Wireless Technology

Indoor wireless coverage will employ Wi-Fi 6 (802.11ax) access points supporting high throughput and lower latency. Segmentation of wireless networks into enterprise SSIDs with WPA3 encryption will enhance security. WPA3 provides improved security against brute-force attacks, ensuring data confidentiality for wireless users. Dual-band (2.4 GHz and 5 GHz) networks will accommodate various device compatibilities.

High Availability in Data Centers

Data centers will utilize redundant power supplies, cooling systems, and network components. High-availability configurations, such as clustering and active-active databases, will ensure continuous operation even during hardware failures. Storage Area Networks (SAN) with replication technologies will protect data integrity and facilitate disaster recovery.

Justification of Recommendations

The choices of fiber optic cabling and high-speed Ethernet align with industry standards for enterprise networks as documented by Cisco (2021), supporting scalability and security. Implementing VLAN segmentation and advanced firewalls aligns with recommendations from the National Institute of Standards and Technology (NIST, 2020) for secure network architecture. Deployment of IDS/IPS solutions follows guidelines by Palo Alto Networks (2022) for intrusion prevention. Using VPNs with AES-256 encryption is supported by the Internet Engineering Task Force (IETF, 2018) to ensure confidentiality across inter-site communications. Wireless security enhancements through WPA3 are adopted from Wi-Fi Alliance (2020), offering state-of-the-art protection against evolving threats. High availability strategies are reinforced by ANSI/TIA standards (TIA, 2019) for data center resilience.
