Diffie-Hellman and RSA are two popular algorithms for secure communication. They fixed the problem of former cryptography, which was the key distribution problem and digital signature problem based on number theory.
Firewalls, tunnels, and network intrusion detection are some of the most important concepts in network security. A firewall is a device or software that is used to monitor and control network traffic. It is typically used to protect a network from unauthorized access. A tunnel is a way to connect two networks securely over the internet. Network intrusion detection is used to detect and prevent unauthorized access to a network. In this blog, we will explore each of these concepts in more detail.
