CCSK Exam Dumps - Cloud Security Alliance Cloud Security Knowledge Questions and Answers

The primary objective of posture management in a cloud environment is to ensure that cloud configurations are continuously monitored to ensure compliance with security policies, best practices, and regulatory requirements.Posture management involves assessing and maintaining the security posture by identifying misconfigurations, vulnerabilities, or non-compliant resources, and ensuring that the cloud environment remains secure and aligned with organizational policies.

Automating incident response procedures is important but is not the primary focus of posture management, which focuses more on proactive configuration and security monitoring. Optimizing cloud cost efficiency is a key concern in cloud management, but it is not the main focus of posture management, which deals with security and compliance. Managing user access permissions is related to Identity and Access Management (IAM), which is a separate aspect of cloud security from posture management.

In the context of Function as a Service (FaaS), trigger events are primarily defined in addition to the functions themselves. FaaS allows you to run individual functions in response to events, such as HTTP requests, file uploads, database changes, or messages in a queue. These trigger events initiate the execution of the serverless function, making them a core part of FaaS architecture.

Data storage is not directly defined by FaaS, as storage is typically managed separately (e.g., cloud storage or databases). Network configurations are not the main focus of FaaS, since cloud providers manage the underlying network infrastructure. User permissions may be relevant but are typically handled through identity and access management (IAM), not directly tied to the definition of a FaaS function.

The correct answer isA. Authorization. In Identity and Access Management (IAM),authorizationis the process of determining whether a subject (user, application, or device) has the right to access a specific system object, such as networks, data, or applications. Authorization decisions are made after successful authentication and are based on the subject's permissions, roles, or attributes.

Key Characteristics of Authorization:

Decision Making:Determines if access ispermitted or deniedbased on policies or permissions.

Role and Attribute-Based Access:Often uses Role-Based Access Control (RBAC) or Attribute-Based Access Control (ABAC) mechanisms to enforce policies.

Post-Authentication Process:Occursafter authenticationhas verified the user's identity.

Resource-Specific:Determines the level of access or specific operations (like read, write, execute) a user is allowed.

Example Scenario:

When a user logs into a cloud platform, the system firstauthenticatesthe user (verifies their identity) and thenauthorizestheir access to specific resources, such as viewing data in an S3 bucket or managing a VM instance. The access policies define what actions the authenticated user can perform.

Why Other Options Are Incorrect:

B. Federation:Involves linking a user's identity across multiple systems or domains but does not decide access permissions.

C. Authentication:The process of verifying a user's identity, typically through passwords, biometrics, or multi-factor authentication (MFA), but it does not determine resource access.

D. Provisioning:Refers to creating and managing user accounts and permissions, but it does not make real-time access decisions.

Real-World Context:

In cloud environments, services like AWS IAM or Azure AD use policies toauthorizeuser actions after they have beenauthenticated. For instance, an AWS IAM policy might allow a user to list S3 buckets but deny deletion.

A Service Registry lists approved services, making it easy for teams to find and integrate compliant services. Reference: [CCSK Knowledge Guide, Domain 3 - Risk and Compliance Tools]

Insecure interfaces and APIs can expose data to unauthorized users, which is a significant security risk. If the API or interface is not properly secured with authentication, authorization, and encryption measures, attackers may exploit vulnerabilities to gain unauthorized access to sensitive data or control over cloud services. This can lead to data breaches and loss of confidentiality.

Ensuring secure data encryption at rest is important, but it is not directly related to insecure interfaces and APIs, which are more about securing data during transmission or interaction. Man-in-the-middle attacks can occur if APIs and interfaces are not properly secured with encryption, but this is a more specific type of attack rather than the primary risk. Increased resource consumption on servers is not typically associated with insecure interfaces or APIs. This might be a result of other issues, like poorly optimized APIs.
