A perimeter-based network security strategy relies on firewalls, routers, and other devices to create a boundary between the internal network and the external network. This strategy assumes that every internal endpoint can be trusted, and that any threat comes from outside the network. However, this assumption is flawed, as internal endpoints can also be compromised by malware, phishing, insider attacks, or other methods. Once an attacker gains access to an internal endpoint, they can use it to move laterally within the network, bypassing the perimeter defenses. Therefore, a perimeter-based network security strategy is not sufficient to protect an organization's endpoint systems, and a more comprehensive approach, such as Zero Trust, is
