CSA CCZT Exam Actual Questions

Optimal compliance posture is mainly achieved through two key ZT features: never trusting and reducing the attack surface. Never trusting means that no entity or resource is assumed to be trustworthy or secure by default, and that every request for access or transaction is verified and validated before granting access or allowing the transaction. Reducing the attack surface means that the exposure and vulnerability of the assets and resources are minimized by implementing granular and dynamic policies, controls, and segmentation. These two features help to ensure that the organization complies with the security standards and regulations, and that the risks of breaches and incidents are reduced.

A key architectural consideration that needs to be taken into account while deploying SDP is how SDP deployment fits into existing network topologies and technologies. This is because SDP deployment may require changes or adaptations to the existing network infrastructure, such as routers, switches, firewalls, VPNs, etc. SDP deployment may also affect the network performance, availability, scalability, and resilience. Therefore, it is important to assess the impact and compatibility of SDP deployment with the existing network topologies and technologies, and to plan and design the SDP deployment accordingly.

The first step for an organization in defining priorities for ZT planning is to determine the current state of its network, security, and business environment. This involves conducting a comprehensive assessment of the existing IT infrastructure, systems, applications, data, and assets, as well as the threats, risks, and vulnerabilities that affect them.The current state analysis also involves identifying the gaps, challenges, and opportunities for improvement in the current security posture, as well as the business goals, objectives, and requirements for ZT implementation12. By determining the current state, the organization can establish a baseline for measuring the progress and impact of ZT, as well as prioritize the most critical and urgent areas for ZT adoption.

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.

In a ZTA, automation and orchestration can increase security by using the following means:

Infrastructure as code (laC): laC is a practice of managing and provisioning IT infrastructure through code, rather than manual processes or configuration tools1.laC can increase security by enabling consistent, repeatable, and scalable deployment of ZTA components, such as policies, gateways, firewalls, and micro-segments2.laC can also facilitate compliance, auditability, and change management, as well as reduce human errors and configuration drifts3.

Identity lifecycle management: Identity lifecycle management is a process of managing the creation, modification, and deletion of user identities and their access rights throughout their lifecycle4.Identity lifecycle management can increase security by ensuring that users have the appropriate level of access to resources at any given time, based on the principle of least privilege5.Identity lifecycle management can also automate the provisioning and deprovisioning of user accounts, enforce strong authentication and authorization policies, and monitor and audit user activity and behavior6.
