Question

In comparison with traditional on-premises infrastructure configurations, defining ACLs in a CSP relies on:

Answers

native applications.
containerization.
serverless configurations.
correct

defined networking.
secure access service edge.

Explanation

The correct answer is: D. Software-Defined Networking (SDN)

In a cloud service provider (CSP) environment, Access Control Lists (ACLs) are typically managed through Software-Defined Networking (SDN). SDN allows for:

Dynamic management: ACLs can be defined, updated, and managed programmatically through APIs or centralized controllers, rather than static configurations on individual devices.
Cloud integration: CSPs use SDN to implement network-level policies, including traffic segmentation, access restrictions, and security rules, across their virtualized network infrastructure.
Scalability and flexibility: SDN enables defining and enforcing ACLs across distributed and scalable cloud networks, which is not easily achievable with traditional on-premises infrastructure.

Why the other options are incorrect:

Cloud-native applications:

Incorrect: While cloud-native applications are designed for cloud environments, they are unrelated to the management or definition of ACLs.

Containerization:

Incorrect: Containerization involves packaging applications and their dependencies, but it does not inherently manage network ACLs. It is more focused on application deployment and isolation.

Serverless configurations:

Incorrect: Serverless configurations abstract the underlying infrastructure, focusing on event-driven execution of code. ACLs are typically managed at the network level, not within serverless functions.

Secure Access Service Edge (SASE):

Incorrect: SASE is a security framework combining network security functions (e.g., CASB, SWG) with WAN capabilities, but it is not specifically focused on ACLs within CSP environments.
