Question 1:
You are tasked with designing a secure network infrastructure for a medium-sized company. Outline the key components and protocols you would incorporate to ensure robust network security.

Solution:
Creating a secure network infrastructure is paramount to safeguarding sensitive information and preventing unauthorized access. Here's a comprehensive approach:

1.     Firewall Implementation: Deploying a firewall at the network perimeter to monitor and control incoming and outgoing traffic is crucial. Configure firewall rules to allow only legitimate traffic while blocking malicious attempts.

2.     Virtual Private Network (VPN): Implementing VPN technology enables secure remote access to the company's network. Utilize protocols like IPSec or SSL/TLS to encrypt data transmitted over the network, ensuring confidentiality.

3.     Intrusion Detection System (IDS) and Intrusion Prevention System (IPS): Deploy IDS to detect suspicious activities and potential security breaches within the network. IPS complements IDS by actively blocking or mitigating detected threats in real-time.

4.     Strong Authentication Mechanisms: Enforce robust authentication methods such as multi-factor authentication (MFA) to verify the identity of users accessing the network resources. Utilize strong passwords and consider biometric authentication for added security.

5.     Regular Security Audits: Conduct periodic security audits to identify vulnerabilities and assess the effectiveness of security measures. Address any weaknesses promptly to maintain a secure network environment.

Question 2:
Explain the concept of subnetting in IPv4 addressing and provide an example illustrating its implementation.

Solution:
Subnetting is a technique used to divide a large IP network into smaller, manageable subnetworks, known as subnets. It helps optimize address allocation and enhances network efficiency. Here's how subnetting works:

Example:
Suppose we have the IP address 192.168.1.0 with a subnet mask of 255.255.255.0 (or /24 in CIDR notation).

To subnet this network into smaller subnets, we borrow bits from the host portion of the IP address to create additional subnet bits. Let's borrow 3 bits, resulting in a subnet mask of 255.255.255.224 (or /27 in CIDR notation).

With the new subnet mask, each subnet can accommodate up to 32 (2^5) host addresses. The available subnets would be:

• 192.168.1.0/27
• 192.168.1.32/27
• 192.168.1.64/27
• and so on…

This allows for efficient utilization of IP addresses and facilitates better network management.

In conclusion, mastering computer network assignments requires a solid understanding of fundamental concepts and the ability to apply them effectively.
