Zero Trust Changed CCZT Questions

For a successful implementation of Zero Trust security, planning and aligning incident and response management processes with existing access procedures are crucial. These processes ensure that the organization is prepared to effectively respond to security incidents and breaches, minimizing potential impacts. Aligning these processes with Zero Trust principles enhances the organization's resilience and ability to quickly adapt to threats, maintaining the integrity and availability of its systems and data​​.

To ensure an acceptable user experience when implementing SDP, a security architect should collaborate with IT to model and plan the user experience, client software distribution, and device onboarding processes. This is because SDP requires users to install and use client software to access the protected resources, and the user experience may vary depending on the device type, operating system, network conditions, and security policies. By modeling and planning the user experience, the security architect and IT can ensure that the SDP implementation is user-friendly, consistent, and secure.

ZTA is based on the principle of never trusting any user or device by default, regardless of their location or ownership. ZTA policies can use various methods to verify the identity and context of third-party users and devices, such as tokens, certificates, multifactor authentication, device posture assessment, etc. ZTA policies can also enforce granular and dynamic access policies that grant the minimum necessary privileges to third-party users and devices for accessing specific resources, while hiding all other assets from their view. This reduces the attack surface and prevents unauthorized access and lateral movement within the network.

In a ZTA, a policy decision point (PDP) is a logical component that evaluates the incoming signals from an entity requesting access to a resource against a set of access determination criteria, such as identity, context, device, location, and behavior1. A PDP then makes a decision to grant or deny access, or to request additional information or verification, based on the policies defined by the policy administrator1. A policy enforcement point (PEP) is a logical component that uses the incoming signals from the PDP to open or close a connection between the entity and the resource1. A PEP acts as a gateway or intermediary that enforces the decision made by the PDP and prevents unauthorized or risky access2.
