Network Security Principles

Overview

In today’s interconnected world, securing networks is more critical than ever. This course empowers learners to gain essential tools and strategies needed to defend computer networks and data from cyber threats. You’ll dive into key topics such as firewalls, VPNs, access controls, and security monitoring, learning how each one contributes to a safe and resilient IT environment. Beyond foundational knowledge, you’ll gain experience understanding advanced techniques like Authentication, Authorization, and Accounting (AAA) and Role-Based Access Control (RBAC). Through guided content, you’ll build confidence in implementing strong security measures and responding to potential incidents. Whether you’re starting your cybersecurity journey or looking to deepen your expertise, this course provides a comprehensive and up-to-date foundation to help you safeguard networks in the digital age.

Syllabus

Rule-Based Security: Access Control Lists

One of the common approaches to implementing rule-based security is by configuring access control lists (ACLs). ACLs can be configured on a wide range of networking devices like routers, switches, firewalls, and wireless access points. In this topic, you will learn about the use of access control lists to enhance the security of your network.

Synergy of GBP, NAC, and 802.1X

Network security and access control mechanisms are essential to protect the sensitive data and resources of organizations. Three important components that play a vital role in achieving this objective are Group-Based Policy (GBP), Network Access Control (NAC), and 802.1X. In this module, you will learn about this powerful trio, which forms a comprehensive approach to modern network security.

Fortifying Networks: Firewalls

In this module, you will learn about two essential components of network security that work together to safeguard networks from cyber threats: firewall and the intrusion prevention system (IPS).

Securing Connections via VPN

In this module, you will learn about virtual private network (VPN) technology and how it creates a secure tunnel to offer privacy and safety to users.

Secure Access Control: AAA and RBAC

To ensure the strong security, confidentiality, and safety of the resources, systems, and data, it is important to provide the right set of access controls to users. By implementing effective access control, businesses can reduce the risk of data breaches, unauthorised modifications, and other security incidents. In this module, you will learn about two popular access control mechanisms: authentication, authorization, and accounting (AAA) and Role-Based Access Control (RBAC).
