In SaaS and PaaS, which access control method will ZT help define
for access to the features within a service?
ABAC is an access control method that uses attributes of the requester, the resource, the environment, and the action to evaluate and enforce policies. ABAC allows for fine-grained and dynamic access control based on the context of the request, rather than predefined roles or privileges. ABAC is suitable for SaaS and PaaS, where the features within a service may vary depending on the customer's needs, preferences, and subscription level. ABAC can help implement ZT by enforcing the principle of least privilege and verifying every request based on multiple factors.

SDP incorporates single-packet authorization (SPA). After
successful authentication and authorization, what does the client
usually do next? Select the best answer.
After successful authentication and authorization, the client typically sends an SPA packet to the controller, which acts as an intermediary in authenticating the client's request before access to the accepting host is granted.

Which of the following is a required concept of single packet
authorizations (SPAs)?
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
Which architectural consideration needs to be taken into account
while deploying SDP? Select the best answer.
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.
