Course Overview

Network firewalls are crucial components of a security infrastructure because they serve as one of the primary lines of defense in a multi-layered network, protecting against unauthorized access and malicious threats from the internet or other untrusted networks. This course will discuss the concepts of defense in depth and segmentation, contrasting them with the use of just an edge firewall. Combine theoretical knowledge with practical exercises to apply concepts to real-world scenarios, ensuring firewalls are both robust and easy to manage. In the course, you will implement a network firewall, connect various devices, and control network traffic flowing between connected devices and the outside world. By placing firewalls at the perimeter and in-depth, safeguard organizational networks against cyber threats, enforce access control policies, prevent unauthorized access, monitor traffic, and ensure compliance with regulatory requirements. In addition to practical implementations, the course emphasizes the essentials of firewall naming conventions, rule organization, and the strategic use of objects and aliases to maintain an efficient and manageable firewall system. Effectively name firewalls and firewall rules to ensure clarity and ease of management. Best practices for organizing firewall rules will be explored to optimize performance and enhance security. Furthermore, you will create and use objects and aliases, simplifying rule management and improving scalability by abstracting complex IP addresses and network information into understandable labels. With the skills gained in this course, you will be able to implement a network firewall and apply various techniques to ensure confidentiality, integrity, and availability using hands-on practical exercises
