Cloud Security Alliance CCSK - Certificate of Cloud Security Knowledge v5 (CCSKv5.0)

In the CSA Security Guidance v4.0, Domain 12: Identity, Entitlement, and Access Management, authentication is explicitly defined as the process that verifies the identity of a user, process, or device before granting access.

"Authentication is the act of verifying the identity of a user, process, or device, often as a prerequisite to allowing access to resources in an information system."

— CSA Security Guidance v4.0, Domain 12

Here's what each term means:

Authentication = Verifies identity

Authorization = Determines access rights

Entitlement = Set of access rights assigned to a user

Assertion = Statement from an identity provider, often used in federation

So, authentication must happen before authorization. It's the first gate.

AI can enhance anomaly detection in cybersecurity by analyzing large volumes of data and identifying patterns that deviate from normal behavior. By using machine learning algorithms, AI can improve the accuracy of anomaly detection, reducing false positive alerts. This helps security teams focus on genuine threats while minimizing distractions from irrelevant alerts.

Assisting analysts is a valid benefit of AI, but reducing false positives directly improves anomaly detection capabilities. Threat intelligence refers to gathering and analyzing information about potential threats but isn't directly focused on reducing false positives in the same way as anomaly detection. Automated responses can be part of AI's role in cybersecurity, but reducing false positives is more directly related to improving anomaly detection.
