Engage critical analysis with the material: Evaluate the effectiveness of the security measures proposed. Consider the practical implications of the solutions discussed and identify potential limitations.
Here is what was discussed in the material:
Today, it is important to understand the requirements of the physical network infrastructure for a contemporary university network.
This requires the designer to define the client's unique situation, particularly the current technology, application, and data architecture.
However, the hierarchical network design is considered in the proposed system and the correspondent network will be scalable; performance and security will be increased; and the network will be easy to maintain.
Hierarchical Network Architecture in Campus Networks
It provides a modular topology of building blocks that allow them to evolve easily. A hierarchical design avoids the need for a fully meshed network in which all network nodes are interconnected.
Designing a campus network needs to be strongly built upon the construction of a campus foundation
There are various types of networks such as Personal Area Network (PAN), Local Area Network (LAN), Metropolitan Area Network (MAN), Campus Area Network (CAN), Storage Area Network (SAN) and Wide Area Network (WAN).
Security Issues in Campus Network
There are various types of network attacks and security threats, network attack methodologies, and categorizations of network attacks. The security offer of any network depends on the type of attack. An internal or external attack Could enter through any unprotected ports, and compromise part or the whole network.
However, traditional border firewalls do nothing for this attack. An internal segmentation firewall can help contain damage.
Types of Network Attacks:
Classes of attack might include passive monitoring of communications, active network attacks, close-in attacks, exploitation by insiders, and attacks through the service provider. Information systems and networks offer attractive targets and should be resistant to attack from the full range of threat agents, from hackers to nationstates. A system must be able to limit damage and recover rapidly when attacks occur.
Some Network Attacks
Denial of service (DoS) and ARP Spoofing Attack
Proposed cost-effective design of a Secure Campus Network.
we have outlined in detail several possible solutions in maintaining a network, and the design of our network in order to encompass such solutions.
A. Creation of VLANs (Virtual LAN) for security
b. Implementing Firewall for Internal and External Security to monitor and block or allow network traffic, both incoming and outgoing, on a private network
C. Virtual Private Network (VPN) Use for branch campus
