The network diagram would change from one organization to other, but this is what a general network diagram looks like:
Let’s discuss the components of these diagrams:
External Firewall - This component serves as the network's guardian at the perimeter, standing between the internal network and the internet. It meticulously regulates incoming and outgoing traffic, acting as a crucial defense against external threats.
Router - The router is like a traffic cop, making sure data moves smoothly between the inside network and the vast world of the internet.
Attack Detection System (ADS) - This component takes on the role of a watchful guard, keeping an eye out for any suspicious activity within the network. Connected to a honeypot server, it's particularly attuned to spotting and responding to potential threats.
FTP server, mail exchange, and file server - Distributed across the server switch, the FTP server facilitates file transfers, the mail exchange manages email communication, and the file server handles storage needs, collectively forming the backbone of internal services.
Internal firewall - Adding an extra layer of defense within the internal network, this component stands connected to the server switch. It carefully regulates traffic between different segments, safeguarding against potential threats that may emerge from within.
Internal switch - This is like a central hub, connecting all the important pieces in the network. This component helps in interconnecting critical components within the network. It acts as a bridge, linking servers, firewalls, and other devices, facilitating efficient data exchange.
Proxy server - Acting as an intermediary between internal users and the internet, it manages and filters internet access, adding a level of control and security to online activities.
Database server and Directory server - Connected to the internal switch, they handle crucial operations, with the database server managing data repositories and the directory server overseeing directory services.
VLANs (Virtual Local Area Networks) - This component is intricately connected to the internal switch. These VLANs provide segmentation, enhancing network manageability and security by isolating specific groups of devices and users.
