Explore defensible architecture and zero-trust models from the standpoint of a security architect. In this 14-video course, you will learn about tools used to address the challenges of network security and review common security models and standards for network security. Key concepts covered here include challenges and deficiencies of traditional security architectures; e standards that address the challenges of security architectures; and concepts and approaches to defensible architecture. Next, learners will examine some fundamentals for the zero-trust model for security; explore the security architecture needs for layers 1, 2, and 3; and delve into the principle of least privilege and how it pertains to security architecture. Learn about the security benefit of reproducible builds; learn how to configure a deny-first firewall using uncomplicated firewall (ufw); and learn how to configure a firewall to block all but a trust subnet. Finally, learners will observe how to configure a VPN service by using WireGuard; how to configure a secure VPN client to connect to a VPN server; and how to configure a firewall to block untrusted egress.
