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?
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.
Which ZT tenet is based on the notion that malicious actors reside
inside and outside the network?
The ZT tenet of assume breach is based on the notion that malicious actors reside inside and outside the network, and that any user, device, or service can be compromised at any time. Therefore, ZT requires continuous verification and validation of all entities and transactions, and does not rely on implicit trust or perimeter-based defenses
During ZT planning, which of the following determines the scope of
the target state definition? Select the best answer.
Risk assessment is the process of identifying, analyzing, and evaluating the risks that an organization faces in achieving its objectives. Risk assessment helps to determine the scope of the target state definition for ZT planning, as it identifies the critical assets, threats, vulnerabilities, and impacts that need to be addressed by ZT capabilities and activities. Risk assessment also helps to prioritize and align the ZT planning with the organization's risk appetite and tolerance levels.
Of the following options, which risk/threat does SDP mitigate by
mandating micro-segmentation and implementing least privilege?
SDP mitigates the risk of broken access control by mandating micro-segmentation and implementing least privilege. Micro-segmentation divides the network into smaller, isolated segments that can prevent unauthorized access and contain lateral movement. Least privilege grants the minimum necessary access to users and devices for specific resources, while hiding all other assets from their view. This reduces the attack surface and prevents attackers from exploiting weak or misconfigured access controls
