Project Assignment Overview

For the completion of this project, we have chosen to focus on Target Corporation, which suffered a significant data breach in 2013 resulting in the loss of 40 million credit card records. This incident highlighted numerous vulnerabilities and deficiencies in their cybersecurity infrastructure, leading to a need for an Information Security Management Program (ISMP) and an Information Security Management Framework (ISMF).

1. Roles and Responsibilities

Understanding the importance of defining roles within a cybersecurity team is crucial for the effective implementation of a security strategy. Below are the roles within our team and their respective responsibilities as aligned with a RACI (Responsible, Accountable, Consulted, Informed) chart:
| Role | Responsibility | RACI |
|----------------------------------|-----------------------------------------------------------|--------------|
| Senior Manager | Provide overall project direction and strategic oversight. | A |
| Chief Information Security Officer | Compiling and enforcing the ISMP and ISMF. | R |
| Cyber Security Professionals | Technical risk assessments, implementation of security measures. | R |
| Compliance Analyst | Ensure alignment with regulations and standards. | C |
| Auditor | Review and assess the effectiveness of the remediation measures. | I |

2. Project Charter

Project Goals:
- Develop a comprehensive ISMP and ISMF tailored to the needs of Target Corporation.
- Transition from a reactive to a proactive security posture.
Objectives:
- Identify existing vulnerabilities and threats.
- Employ best practices according to industry standards (ISO 27001, NIST).
- Establish a governance framework for security management.
Deliverables:
- Completed ISMP and ISMF documents.
- Risk assessment report and a roadmap for implementation.

3. Organizational Overview

Target Corporation is a retail giant with a significant online and physical presence. Founded in 1902, it operates on a business model focused on providing a limited assortment of merchandise at competitive prices. Its mission is to offer an unparalleled shopping experience which it aligns with its vision for growth and customer satisfaction.

4. Security Posture Before and After the Attack

Before the 2013 breach, Target's security posture was reactive, characterized by minimal cybersecurity policies, lack of incident response plans, and poorly integrated security controls. Post-attack, the organization implemented comprehensive security measures, including a re-evaluation of their cybersecurity strategies and a movement towards a proactive posture that emphasizes risk management and compliance.

5. Information Security Management Plan (ISMP)

The proposed ISMP for Target Corporation will encapsulate:
- Assessment of Current Risks: Identify and document all cybersecurity risks.
- Policy Development: Create policies governing information security practices.
- Training Programs: Implement ongoing training for all employees regarding security protocols.
- Monitoring and Reporting: Establish monitoring tools to assess the effectiveness of security practices continually.

6. Threat Model Approach

The organization will utilize a threat model to map vulnerabilities against potential threats:
- Threats: Malicious attacks, insider threats, system failures.
- Vulnerabilities: Outdated systems, poor access control, lack of employee training.
- Risk Assessment: Evaluate the impact and likelihood of each identified risk to prioritize mitigation strategies (Shostack, 2014).

7. Information Security Management Framework (ISMF)

The ISMF will follow the NIST Cybersecurity Framework, divided into five core functions:
- Identify: Asset management and risk assessment.
- Protect: Implement appropriate safeguards (encryption, access control).
- Detect: Continuous monitoring systems for early threat detection.
- Respond: Incident response planning and communication protocols.
- Recover: Plan for business continuity and disaster recovery strategies.

8. Framework Tier

Target Corporation will aim for a minimum of Tier 3 (Defined) in terms of the Framework Tier approach, which would involve risk-informed decision-making and the regular updating of security measures as per organizational needs.

9. Security Governance Approach

Implementing a comprehensive security governance structure including policies, standards, and accountability measures is essential. The governance approach will ensure that security measures align with the overall business strategy, and will include regular audits to enforce adherence to the established policies.

10. Strategic, Tactical, and Operational Security Plans

Strategic: Establish long-term goals regarding data protection and compliance.
Tactical: Develop specific initiatives like deploying an updated firewall system.
Operational: Daily monitoring of cybersecurity systems and regular training sessions for staff.

11. Development of Policies and Procedures

Utilizing frameworks such as ISO 27001 and NIST, the following documents and policies will be developed:
- Program Policy: Outline an organization-wide policy for information security.
- Issue-specific Policy: Address specific areas such as data encryption.
- System-specific Policy: Focus on security measures around particular systems.
- Standards and Baselines: Define minimum security requirements.
- Guidelines and Procedures: Provide detailed instructions for implementation.

12. Asset Management and Security Approach

Target will implement an asset management strategy that classifies assets based on sensitivity and importance, ensuring confidentiality, integrity, and availability through established controls.

13. Lessons Learned from the Breach

- Implementation of stronger security measures.
- Regular audits and vulnerability assessments are essential.
- Employee training is critical for security awareness and compliance.
- Importance of having an incident response plan.
- The need for continuous monitoring of systems.
- Updating systems and software regularly.
- Engaging third-party security assessments for unbiased reviews (Johnson, 2021).

14. Proposed Preventative Measures

1. Adopt a zero-trust approach to data access.
2. Implement two-factor authentication for user access.
3. Schedule regular penetration tests and vulnerability assessments.
4. Foster a culture of security awareness among employees.
5. Establish a robust incident response team.
6. Utilize advanced threat detection systems.
7. Maintain an up-to-date inventory of all assets (Bertino & Islam, 2017).

Conclusion

Through the comprehensive approach laid out in this report, Target Corporation can transition to a proactive cybersecurity posture, ensuring that customer data is adequately protected, thus restoring stakeholder confidence and mitigating future risks.
