The scope of the target state definition in Zero Trust planning is significantly influenced by an organization's risk appetite. This entails a strategic evaluation of the level of risk an organization is willing to accept in pursuit of its objectives. Continuous authentication and authorization, integral to Zero Trust, adapt to the dynamic state of threats and the organization's risk posture, ensuring that authorization decisions align with the prevailing risk appetite and the changing security landscape​​.

One of the core principles of Zero Trust (ZT) is to “never trust, always verify” every request for access to a resource, regardless of where it originates or what resource it accesses1. This means that ZT does not rely on implicit trust based on network perimeters, device types, or user roles, but rather on explicit verification based on multiple data points, such as user identity, device health, location, service, data classification, and anomalies1.

Software-Defined Perimeter (SDP) features such as server isolation, single packet authorization (SPA), and dynamic drop-all firewalls are designed to protect against a range of threats, including Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks. These SDP capabilities help to shield servers from unwanted or malicious traffic by ensuring that only authenticated and authorized users can establish connections. By minimizing the server's exposure to the internet and reducing its attack surface, SDP effectively mitigates the risk of DoS/DDoS attacks, which aim to overwhelm servers with excessive traffic, thereby ensuring the availability and reliability of critical services within a Zero Trust framework.
