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

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.

TheCascade-and-filter approachis a method used in cloud security to handle incoming data logs efficiently. It prioritizes logs for threat detection byapplying multiple sequential filters, where each filter progressively narrows down the data. This approach helps in:

Layered threat detection:Early filters eliminate non-critical data, while subsequent filters perform more detailed analysis.

Efficient processing:Reduces the volume of data passed through advanced and resource-intensive filters.

Improved accuracy:Allows focusing on the most relevant security events.

For example, in a cloud environment, the first filter might check for known malicious IP addresses, the second might look for suspicious file types, and subsequent filters may perform behavioral analysis or anomaly detection.

Why Other Options Are Incorrect:

B. Parallel processing approach:This method processes logs simultaneously, not sequentially, and is less efficient for prioritizing threats.

C. Streamlined single-filter method:Uses a single filter for all data, which lacks depth and thoroughness in identifying complex threats.

D. Unfiltered bulk analysis:This approach is resource-intensive and inefficient, as it does not prioritize or filter logs.

Real-time visibility allows for monitoring container behavior during runtime, helping to identify and respond to security incidents as they occur. Reference: [Security Guidance v5, Domain 8 - Cloud Workload Security]

When establishing a cloud incident response program, responders need persistent read access to resources, such as logs, configurations, and system data, in order to analyze and investigate incidents effectively. This access allows them to view and understand the nature of the incident, the affected systems, and any potential risks. In critical situations, controlled write access is necessary to take remedial actions, such as stopping malicious processes, patching vulnerabilities, or implementing other immediate security measures, but write access should be restricted and carefully managed to prevent misuse or errors.

Access limited to log events is too restrictive, as responders need more than just log events to fully analyze incidents. Unlimited write access for all responders is too broad and dangerous; unrestricted write access could lead to accidental or malicious changes to critical systems. Full-read access without any approval process could be dangerous if it allows responders too much access without appropriate oversight, potentially violating privacy or security policies.

Immutable containers are not altered post-deployment, ensuring the integrity of the deployed environment and reducing the risk of unauthorized modifications. Reference: [CCSK v5 Curriculum, Domain 8 - Cloud Workload Security][16†source].
