Secure network design and architecture
When designing and implementing secure network architectures, the goal is to ensure the confidentiality, integrity, and availability of the network resources. One common concept used in network design is the DMZ , which stands for demilitarized zone. The DMZ is a segregated network segment that acts as a buffer zone between the internal network and the external untrusted network, typically the internet. It provides an additional layer of security by hosting publicly accessible services, such as web servers or email servers, while isolating them from the internal network. Another important concept is a Virtual Private Network (VPN) . A VPN creates a secure, encrypted connection over a public network, such as the internet, allowing remote users or branch offices to securely access the internal network resources. It ensures the confidentiality of the data transmitted over the network by encrypting the communication between the VPN client and the VPN server. Secure routing protocols play a...
