Cloud Computing Threats: Comprehensive Guide for CEH Exam

Why Understanding Cloud Computing Threats is Important

Understanding cloud computing threats is crucial for ethical hackers and security professionals because organizations increasingly store sensitive data in cloud environments. Being able to identify and mitigate these threats is essential for protecting client data, maintaining compliance with regulations, and ensuring business continuity. On certification exams like CEH, questions about cloud threats test your ability to recognize vulnerabilities specific to distributed computing environments.

What Are Cloud Computing Threats?

Cloud computing threats are security risks, vulnerabilities, and attack vectors that specifically target cloud-based infrastructures, platforms, and services. These threats exploit the unique characteristics of cloud computing, such as multi-tenancy, shared resources, broad network access, and dynamic provisioning.

Common cloud computing threats include:

1. Account or Service Hijacking - Attackers gain unauthorized access to cloud accounts through stolen credentials

2. Data Breaches - Unauthorized access to sensitive information stored in cloud environments

3. Insecure APIs - Vulnerabilities in application programming interfaces that provide access to cloud services

4. Denial of Service (DoS) attacks - Attempts to make cloud resources unavailable to intended users

5. Insufficient Due Diligence - Organizations moving to cloud computing models may not understand security implications

6. Shared Technology Vulnerabilities - Exploits targeting shared infrastructure components affecting multiple clients

7. Advanced Persistent Threats (APTs) - Targeted attacks that persist over extended periods

8. Data Loss - Permanent loss of data due to inadequate backup procedures or provider failures

9. Malicious Insiders - Threats from within the cloud provider organization

10. Abuse of Cloud Services - Using cloud resources for unauthorized activities like cryptomining or DDoS attacks

How Cloud Computing Threats Work

Cloud threats leverage various attack vectors:

Multi-tenancy exploitation: Attackers attempt to breach isolation mechanisms to access other tenants' data.

API vulnerabilities: Insecure APIs can allow unauthorized access or privilege escalation.

Credential theft: Through phishing, password spraying, or brute force attacks to gain legitimate access.

Misconfiguration: Security settings improperly configured, leaving resources exposed.

Supply chain vulnerabilities: Compromising third-party services integrated with cloud platforms.

Virtualization flaws: Exploiting hypervisor or container vulnerabilities to escape isolation.

The distributed nature of cloud computing creates an expanded attack surface with unique security challenges compared to traditional on-premises environments.

Exam Tips: Answering Questions on Cloud Computing Threats

1. Know the shared responsibility model - Understand which security aspects are managed by the provider versus the customer in different service models (IaaS, PaaS, SaaS).

2. Memorize the top cloud threats - Be familiar with the OWASP Top 10 for cloud security and CSA's Top Threats to Cloud Computing.

3. Focus on threat mitigation - Questions often ask how to address specific cloud threats; know countermeasures for each threat type.

4. Understand cloud-specific technologies - Know security mechanisms for containers, serverless computing, and virtual networks.

5. Pay attention to compliance requirements - Be familiar with regulations affecting cloud security (GDPR, HIPAA, etc.).

6. Practice scenario-based questions - Exams often present real-world scenarios requiring you to identify threats and recommend solutions.

7. Learn cloud security terminology - Familiarize yourself with terms like CASB, CSPM, CWPP, and cloud workload security.

8. Study cloud provider-specific security controls - Know the differences between security features in major providers (AWS, Azure, GCP).

9. Recognize the signs of specific attacks - Know indicators that might suggest account hijacking, data exfiltration, or privilege escalation.

10. Use process of elimination - For multiple-choice questions, eliminate clearly incorrect answers to improve your chances.

When answering exam questions about cloud computing threats, carefully read the scenario details and identify which specific cloud service model is being discussed, as this affects the applicable threats and security responsibilities.
