Just as penetration testers try to get access to an organisation electronically, red teams try to get physical access to the organisation. They use a combination of Open Source Intelligence gathering and social engineering to get access.

As the name suggests, this is the process of providing access to systems from a remote location. For example, many people are given access to their work systems when not in the office.

A Remote Access Trojan (RAT) is a piece of malware which enables attackers to gain control of a target machine from a remote location. When attackers use phishing techniques, the first step after a link is created is often to implement a RAT. This enables an attacker to get access to the device and carry on their attack using other tools.
A router is a network device which examines network traffic and forwards it to the most appropriate part of the network.
