Hybrid Cloud Connectivity

Create VPN

WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs), and was designed with the goals of ease of use, high speed performance, and low attack surface. It aims for better performance and more power than IPsec and OpenVPN, two common tunneling protocols. The WireGuard protocol passes traffic over UDP.

Find All IP Addresses and used ports on a Network

On modern operating systems, ports are numbered addresses for network traffic. Different kinds of services use different ports by default.

nmapscan For example, normal web traffic uses Port 80, while POP3 email uses Port 110. One of the ways that a firewall works is by allowing or restricting traffic over a particular port.

Because the ports can cause a security risk, it’s critical to know which ports are open and which are blocked.

Network Scanning

Nmap, short for Network Mapper, is a free, open-source tool for vulnerability scanning and network discovery. Network administrators use Nmap to identify what devices are running on their systems, discovering hosts that are available and the services they offer, finding open ports and detecting security risks.

Tasks

Make sure you have enough practice in the following tasks:

  • Create VPN

  • Discover IP addresses and Ports

  • ping a remote node

  • Use a remote service e.g. Datacollector
