Using the case study and NIST SP 800-53, Identify and prioritize IT Security controls

Using the case study and NIST SP 800-53, identify and prioritize IT security controls that should be implemented. Discuss any applicable US Government regulations/standards that apply to this organization (The organization is from Project 1). Step 1: Review the selected case study and describe at least 10 issues related to security, interoperability, and operations. Step 2: Prioritize and articulate the selected requirements based on immediate need, security posture, complexity, resource availability, and cost. Step 3: Identify at least 4 applicable government regulations/standards that govern how the requirements must be met, implemented, or measured. Provide rationale for why these are applicable. Step 4: Using NIST Special Publication 800-53 select at least 4 security controls that relate to these issues and describe how these controls enhance the security posture or facilitate the secure implementation of these requirements. The deliverable for this assignment is a minimum 5 page, double-spaced paper using Times New Roman 12 font and APA style format. It will also include a minimum of 5 references. The Title/Cover page, illustrations (tables/charts/graphs), or references are not part of the page count but are required.

Paper For Above instruction

The increasing reliance on digital infrastructures in financial institutions underscores the necessity for comprehensive cybersecurity strategies, especially concerning disaster recovery (DR) and business continuity (BC). The case study of Bank Solutions exemplifies the critical need to evaluate current security postures, identify vulnerabilities, and implement robust controls aligned with federal standards such as NIST SP 800-53 and relevant US regulations. This paper systematically reviews the key security issues, prioritizes requirements based on risk and resource considerations, and recommends specific controls to enhance resilience and compliance.

1. Security, Interoperability, and Operations Issues

The case analysis reveals at least ten significant issues impacting Bank Solutions’ security posture and operational effectiveness:

1. The Disaster Recovery and Business Continuity Plan (DRBCP) was last updated in 2009 and last tested in 2007, risking outdated procedures during crises.
2. Critical team members are not trained in DRBCP procedures, increasing the risk of operational failure during emergencies.
3. Without established metrics, response efforts may be inefficient and inconsistent in restoring services.
4. Backup tapes stored informally—some at employees’ homes or in unsecured locations—pose significant risks of loss, theft, or tampering.
5. Although IDS and firewalls are in place, there is no standardized incident handling process, including escalation and evidence preservation.
6. Users with elevated privileges can modify logs, compromising forensic investigations after security incidents.
7. While redundancies exist at the perimeter, there is no clear delineation of responsibilities for backup processing sites, risking data loss or process interruptions.
8. Generic templates have not been adequately customized or tested, increasing downtime risk at smaller facilities.
9. Failures in backup jobs at facilities and reliance on ad hoc storage compromise data integrity and recovery.
10. The current processes lack documentation demonstrating compliance with federal standards, exposing the organization to legal and financial penalties.

2. Requirement Prioritization Based on Risk and Resources

Prioritizing these issues involves assessing their immediate threat level and resource implications. High-priority actions include updating and testing the DRBCP (Issue 1), establishing formal incident response procedures (Issue 5), securing backup storage locations (Issue 4), and formalizing access controls and log integrity protocols (Issue 6). These address vulnerabilities that could have catastrophic operational or financial consequences. Medium-priority issues include training staff (Issue 2), defining RTO/RPO (Issue 3), and enhancing small centers’ plans (Issue 8), which strengthen overall resilience but are less critical during immediate threats. Lower priorities involve addressing backup failures (Issue 9) and formal regulatory compliance documentation (Issue 10), which are essential for long-term sustainability and legal adherence.

3. Applicable US Regulations and Standards

Four key regulations/standards applicable to Bank Solutions include:

• Gramm-Leach-Bliley Act (GLBA): Requires financial institutions to safeguard customer information, enforce privacy regulations, and implement security controls.
• Federal Financial Institutions Examination Council (FFIEC) Guidelines: Provides comprehensive cybersecurity assessment frameworks specific to financial institutions’ needs and operational risk management.
• NIST SP 800-53: Offers a catalog of security controls for federal information systems, applicable by reference to private sector organizations handling sensitive financial data.
• Supervisory Guidance for IT outsourcing: Advocated by federal regulators ensuring that third-party providers (like data centers) meet security standards, critical for disaster recovery infrastructures.

These regulations are applicable because Bank Solutions handles sensitive financial transaction data, must protect consumer privacy, and is subject to federal oversight designed to mitigate operational risks, especially in disaster scenarios. Compliance ensures legal adherence and enhances stakeholder trust.

4. NIST SP 800-53 Controls to Address Key Issues

The selection of controls from NIST SP 800-53 is driven by the issues identified:

1. Control: Contingency Planning (CP-2, CP-4, CP-6): This control mandates formal procedures for developing, testing, and maintaining contingency plans. Implementing it will mandate regular, realistic DR tests, addressing issues of outdated plans and inadequately tested recovery strategies.
2. Control: System and Communications Protection (SC-7, SC-13): These controls enforce encryption, secure boundaries, and data integrity during transmission. They strengthen network defenses, protecting data during backups and transfers which lessens exposure to interception or tampering.
3. Control: Access Control (AC-17, AC-23): These controls specify least privilege and monitoring of privileged activities, ensuring only authorized personnel can modify logs or access sensitive data, thus improving forensic readiness.
4. Control: Incident Response (IR-4, IR-6): Establishes formal procedures for detecting, analyzing, and responding to security incidents, including escalation paths and forensic preservation, directly addressing gaps in incident handling protocols.

Together, these controls improve organizational resilience, protect critical data, support compliance, and facilitate rapid, coordinated responses to security incidents, aligning with best practices in financial cybersecurity management.
