Which of the following is an effective step for identifying cloud vulnerabilities related to improper configuration?

Performing regular vulnerability scans with tools specifically designed for cloud environments is a proactive and effective method for identifying misconfigurations. Cloud Security Posture Management (CSPM) tools, a type of vulnerability scanner, continuously monitor cloud infrastructure against established security benchmarks (e.g., CIS Benchmarks, NIST) and vendor best practices. They automatically detect issues such as overly permissive IAM roles, public-facing storage buckets, and insecure network configurations, which are common sources of cloud vulnerabilities. This automated and continuous assessment is crucial for maintaining a secure posture in dynamic cloud environments.

A. Grant all users administrator-level permissions for easier troubleshooting: This practice violates the principle of least privilege and drastically increases the attack surface, creating vulnerabilities rather than identifying them.
B. Disable logging to reduce storage costs and simplify analysis: Disabling logs eliminates critical visibility required for detecting, auditing, and investigating security incidents, effectively hiding vulnerabilities and misconfigurations from security teams.
D. Rely on default security settings provided by cloud service providers: This is a passive approach that ignores the shared responsibility model. Cloud providers' defaults often prioritize ease of use over security, leaving customers responsible for secure configuration.

1. CrowdStrike. (n.d.). Falcon Cloud Security: Datasheet. CrowdStrike Inc. Retrieved from official vendor documentation. The document states, "Falcon Cloud Security delivers comprehensive breach protection for cloud workloads and containers... It combines CSPM [Cloud Security Posture Management]... to provide continuous posture management and breach protection for cloud infrastructure... [It] identifies misconfigurations across your cloud accounts." This directly supports the use of specialized tools for scanning.

2. Amazon Web Services. (n.d.). Shared Responsibility Model. AWS Documentation. This foundational concept, central to cloud security, clarifies that while the cloud provider secures the cloud of the cloud, the customer is responsible for security in the cloud, which includes proper configuration of services, identity, and access management. Relying on defaults (Option D) neglects this customer responsibility.

3. Pardoll, M. (2022). Lecture 8: Cloud Security. CS 161: Computer Security, University of California, Berkeley. The courseware emphasizes the importance of automated configuration checking and adherence to the principle of least privilege (PoLP) in cloud environments, directly contradicting the insecure practices suggested in options A and D. It highlights that misconfigurations are a leading cause of cloud breaches.
