CAS-005 Exam Dumps : CompTIA SecurityX Certification Exam

The provided code snippet shows a script that captures the user ' s cookies and sends them to a remote server. This type of attack is characteristic of Cross-Site Scripting (XSS), specifically stored XSS, where the malicious script is stored on the target server (e.g., in a database) and executed in the context of users who visit the infected web page.

A. XSRF (Cross-Site Request Forgery) attack: This involves tricking the user into performing actions on a different site without their knowledge but does not involve stealing cookies via script injection.

B. Command injection: This involves executing arbitrary commands on the host operating system, which is not relevant to the given JavaScript code.

C. Stored XSS: The provided code snippet matches the pattern of a stored XSS attack, where the script is injected into a web page, and when users visit the page, the script executes and sends theuser ' s cookies to the attacker ' s server.

D. SQL injection: This involves injecting malicious SQL queries into the database and is unrelated to the given JavaScript code.

The best way to address these requirements is to apply Role-Based Access Controls (RBAC) combined with geolocation policies. RBAC ensures that customers are authenticated and authorized to access only the data they are entitled to, thereby minimizing data exposure risks. At the same time, geolocation policies enforce restrictions on which regions customers can access data from, helping with compliance requirements such as GDPR or regional sovereignty laws.

Option B (replicating data in each customer environment) is inefficient, expensive, and introduces additional risks related to data sprawl. Option C (regional hosting with unique links) complicates access management and does not inherently prevent exposure or enforce strong authentication. Option D (restricting to a single region provider) removes flexibility and may conflict with customer needs for global access.

Therefore, implementing RBAC along with geolocation controls provides fine-grained access management, ensures compliance, prevents unnecessary data exposure, and is scalable for a global cloud environment.

The technique that best addresses the issue of insider threats from employees who have individual access to encrypted material is key splitting. Here’s why:

Key Splitting: Key splitting involves dividing a cryptographic key into multiple parts anddistributing these parts among different individuals or systems. This ensures that no single individual has complete access to the key, thereby mitigating the risk of insider threats.

Increased Security: By requiring multiple parties to combine their key parts to access encrypted material, key splitting provides an additional layer of security. This approach is particularly useful in environments where sensitive data needs to be protected from unauthorized access by insiders.

Compliance and Best Practices: Key splitting aligns with best practices and regulatory requirements for handling sensitive information, ensuring that access is tightly controlled and monitored.
