Do Internet, GSM, and wireless networks belong to the insecure communication channels?
Internet, GSM, and wireless networks are all considered insecure communication channels from the perspective of classical and modern cryptography. To understand why this is the case, one must examine the inherent properties of these channels, the types of threats they face, and the security assumptions made in cryptographic protocol design. 1. Definition of Secure vs.

What is the purpose of the Domain Name System (DNS) in computer networks and the internet?
The Domain Name System (DNS) plays a important role in computer networks and the internet by providing a hierarchical naming system that translates human-readable domain names into IP addresses. This translation is essential for the proper functioning of network communication, as it allows users to access resources on the internet using familiar and meaningful domain
How does Cloud NAT enhance the security of VMs by hiding their private IP addresses from the internet?
Cloud NAT is a key component of Google Cloud Platform (GCP) networking that enhances the security of virtual machines (VMs) by hiding their private IP addresses from the internet. This feature provides a layer of protection by obfuscating the internal network structure and preventing direct access to the private IP addresses assigned to the VMs.
