Computer Networks and Network Security

After completing this module, you will be able to explain and apply IP addressing, IP address structure and network classes, IP protocols, traffic routing, and the IPv6 address schema. You’ll also be able to compare the structure and uses of IPv4 and IPv6. You’ll be able to explain basic network routing principles, Layer 2 and Layer 3 addressing, and Address Resolution Protocols (ARP) and describe the basics of routers and routing table sessions. You'll gain experience you can use in the real world when you learn how to secure a small office/home office (SOHO) network.

In this module, you'll learn about network protocols and security measures, combining theoretical knowledge with practical applications. You will begin with an introduction to application and transport protocols, focusing on UDP and TCP. You will then explore DNS and DHCP and experience a hands-on lab for configuring DHCP and an activity on DNS filtering. Then learn how to use Syslog message logs and network analysis techniques, including port mirroring, promiscuous mode, and user behavior analysis.

This module introduces you to network security techniques, including firewall technologies, stateless and stateful inspections, IDS, and IPS systems. You’ll also examine Network Address Translation (NAT) and file integrity monitoring, along with advanced security measures such as Data Loss Prevention (DLP), Network Access Control, and Endpoint Detection and Response (EDR). You'll conclude this module with a hands-on lab where you can gain real-world experience with an open-source Extended Detection and Response (XDR) application.

In this module, you will apply the course knowledge and hands-on skills you gained in prior modules to complete your final project. During your final project, you complete real-world tasks, including designing a network with subnets, calculating subnet addresses and subnet masks, configuring firewalls, and analyzing website traffic.
