Secure Network Architecture TryHackMe

Показать описание
Networking is one of the most critical components of a corporate environment but can often be overlooked from a security standpoint. A properly designed network permits not only internet usage and device communication but also redundancy, optimization, and security.

In a well-designed network, if a switch goes down, then packets can be redistributed through another route with no loss in uptime. If a web server is compromised, it cannot traverse the network and access important information. A system administrator should be confident that their servers are secure if a random device joins a network, knowing that the device is segmented from the rest of the network and cannot access those systems.

All of these concepts and scenarios are what separate a functional network from a well-designed network.

Throughout this room, we will break down these scenarios or objectives and understand different concepts we can use to implement them in a network. We will also discuss potential threats a network may face even after proper best practices are established.

I think the description is meant to show that default action drop also applies to dmz-wan (?) according to the table and shown in the diagram at the top where the rule changes between dmz-wan / dmz-lan
