Cyb 200 Module Three Case Study Template After Reviewing The Scenar

After reviewing the scenario in the Module Three Case Study Activity Guidelines and Rubric document, fill in the table below by completing the following steps: 1. Specify which Fundamental Security Design Principle applies to the control recommendations by marking the appropriate cells with an X. 2. Indicate which security objective (confidentiality, availability, or integrity) applies best to the control recommendations. 3. Explain your choices in one to two sentences with relevant justifications.

Sample Paper For Above instruction

The scenario involves a security incident where an intern accidentally transferred confidential data to a cloud storage platform, DataStore, resulting in temporary public exposure. From this case, various security controls can be implemented, aligned with fundamental security design principles and security objectives, to prevent similar incidents in the future.

Control Recommendation 1: Deploy an automated tool on network perimeters that monitors for unauthorized transfer of sensitive information and blocks such transfers while alerting information security professionals.

  • Isolation:
  • Encapsulation:
  • Complete Mediation: X
  • Minimize Trust Surface (Reluctance to Trust):
  • Trust Relationships:

Security Objective: Confidentiality. This control is aimed at preventing unauthorized disclosures of sensitive data.

Justification: Monitoring and blocking unauthorized data transfer directly safeguard confidential information by ensuring only permitted data flows occur, aligning with the confidentiality principle.

Control Recommendation 2: Monitor all traffic leaving the organization to detect any unauthorized use.

  • Isolation:
  • Encapsulation:
  • Complete Mediation: X
  • Minimize Trust Surface (Reluctance to Trust):
  • Trust Relationships:

Security Objective: Availability. Ensuring authorized data transfer maintains system availability.

Justification: Continuous monitoring enhances the organization's ability to detect and respond to misuse, thus preserving the availability of critical services and data.

Control Recommendation 3: Use an automated tool, such as host-based data loss prevention, to enforce access controls to data even when data is copied off a system.

  • Isolation:
  • Encapsulation:
  • Complete Mediation: X
  • Minimize Trust Surface (Reluctance to Trust):
  • Trust Relationships:

Security Objective: Confidentiality. This control protects sensitive data from unauthorized access or transfer.

Justification: Enforcing strict access controls, particularly when data is copied or transferred, directly upholds confidentiality by preventing unauthorized data exfiltration.

Additional controls include segregating higher-risk systems, enforcing only necessary resource access, installing application firewalls, implementing multi-factor authentication (MFA), encrypting data-in-motion, and setting security alerts for abnormal login activities. Each recommendation aligns with fundamental security principles like least privilege, layering, and separation to enhance overall security posture.

Responses to Short Questions

1. Is it possible to use DataStore and maintain an isolated environment? Explain your reasoning.

Yes, it is possible to utilize DataStore within an isolated environment by implementing strict access controls, network segmentation, and encryption. Creating a dedicated virtual private cloud (VPC) or using containerization techniques can ensure data is segregated and protected from other tenants, thus maintaining isolation.

2. How could the organization have more effectively applied the principle of minimizing trust surface with DataStore to protect its confidential data? Explain your reasoning.

The organization could have minimized trust surface by limiting DataStore permissions through granular access policies, employing strong encryption for all data in transit and at rest, and implementing multi-factor authentication for accessing cloud services. These measures would reduce reliance on trusting DataStore alone and limit potential attack vectors.

3. How can the organization build a more security-aware culture from the top down to prevent mistakes before they happen? Explain your reasoning.

Building a security-aware culture requires leadership commitment to regular training, fostering open communication about security risks, and establishing clear policies and accountability. When top management emphasizes security priorities, employees are more likely to adhere to best practices and recognize the importance of vigilance, reducing human error and insider threats.
