CSA CCZT Exam - Topic 6 Question 56 Discussion

Question

Scenario: A multinational org uses ZTA to enhance security. They

collaborate with third-party service providers for remote access to

specific resources. How can ZTA policies authenticate third-party

users and devices for accessing resources?

Sylvie · Accepted Answer

C) ZTA policies can be configured to authenticate third-party users
and their devices, determining the necessary access privileges for
resources while concealing all other assets to minimize the attack
surface.

Sylvie · Answer

A) ZTA policies can implement robust encryption and secure access
controls to prevent access to services from stolen devices, ensuring
that only legitimate users can access mobile services.

Sylvie · Answer

B) ZTA policies should prioritize securing remote users through
technologies like virtual desktop infrastructure (VDI) and corporate
cloud workstation resources to reduce the risk of lateral movement via
compromised access controls.

Sylvie · Answer

D) ZTA policies should primarily educate users about secure practices
and promote strong authentication for services accessed via mobile
devices to prevent data compromise.
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.
