Project 2 Deliverables: Security Assessment Report

Project 2 Deliverables security Assessment Report Sari Title Pageii

Develop a comprehensive Security Assessment Report (SAR) and Risk Assessment Report (RAR) based on a cybersecurity breach scenario involving the Office of Personnel Management (OPM). The SAR should include an overview of the organization, network architecture, threats, vulnerabilities, scanning results, database security measures, threat identification, and security issues. The RAR should analyze organizational risks, vulnerabilities, likelihood, impact, and propose remediation strategies, including a high-level plan of actions with milestones.

Assess the organization's vulnerabilities by examining internal and external threats, attack vectors such as phishing, malware, insider threats, and technical exploits like spoofing, DoS, and sniffing. Evaluate security controls like firewalls, encryption, authentication, and auditing mechanisms. Use the OPM breach case to illustrate lessons learned and applicable mitigation techniques. Incorporate scholarly research and credible sources to support analysis and recommendations, demonstrating a thorough understanding of cybersecurity principles, risk management, and security policy formulation.

Introduction

The increasing sophistication of cyber threats necessitates comprehensive security assessments of organizational information systems. The Office of Personnel Management (OPM) breach exemplifies the devastating consequences of vulnerabilities within federal agencies' cybersecurity infrastructure. This paper aims to develop an in-depth Security Assessment Report (SAR) and Risk Assessment Report (RAR) to evaluate the security posture of a hypothetical organization, drawing lessons from the OPM incident. It emphasizes the importance of identifying vulnerabilities, understanding threats, implementing adequate controls, and establishing effective remediation strategies to mitigate potential breaches.

Organization Overview and Network Architecture

The organization under consideration is a mid-sized government agency with a layered network infrastructure comprising a Local Area Network (LAN) and Wide Area Network (WAN). The network architecture includes various interconnected segments: internal intranet, external internet access points, and extranet connections with partners. The organization's core systems include employee databases, operational systems, and administrative functions. The network diagram depicts inner networks separated from external networks via firewalls and demilitarized zones (DMZs). The architecture incorporates cloud computing services, distributed computing platforms, and centralized systems to enhance operational efficiency and scalability.

This design incorporates secure constructs such as virtual private networks (VPNs), secure access gateways, and segmentation to safeguard sensitive data. The rationale for adopting cloud and distributed computing aligns with the need for flexible resource management and resilience, but they also introduce new vulnerabilities requiring reinforced security controls.

Threat Landscape and Threat Intelligence

Analysis of the OPM breach reveals that malicious actors exploited compromised credentials, leveraging phishing and spear-phishing tactics, which highlights the significance of insider threats and external cyber espionage. Threat intelligence indicates the presence of nation-state actors and advanced persistent threats (APTs) targeting sensitive personnel data. Insider threats, including disgruntled employees or inadvertent insiders, pose substantial risks by providing access pathways into secured networks.

Differentiating external threats—such as malware, DDoS attacks, and IP spoofing—from internal threats exposes vulnerabilities at multiple points, especially at access control interfaces and authentication systems. The OPM incident exemplifies the need for robust identity management, continuous monitoring, and comprehensive auditing to detect and deter malicious activities.

Network Scanning and Vulnerability Assessment

Utilizing tools such as Wireshark, network logs were analyzed to detect abnormal traffic patterns, suspicious port activity, and potential covert channels. The findings identified open ports susceptible to scanning and information leakage, highlighting the necessity for strict firewall rules and intrusion detection systems (IDS). Regular vulnerability scanning and patch management are imperative to address known weaknesses, reducing the attack surface.

Database Security and Access Controls

The organization's relational database management system (RDBMS) employs firewalls, encryption, and auditing to protect sensitive data. Firewalls serve to restrict unauthorized access, while encryption techniques like AES ensure confidentiality both at rest and in transit. Auditing mechanisms monitor database transactions and system access, supporting the principles of confidentiality, integrity, and availability. However, lapses in implementing multi-factor authentication and comprehensive logging can diminish these controls' effectiveness, as evidenced in the OPM case where compromised credentials facilitated access.

Threat Identification and Attack Vectors

Potential attack vectors include IP address spoofing, cache poisoning, session hijacking, and distributed denial of service (DDoS). Attack actors range from cybercriminal groups to nation-sponsored entities. The use of intrusion detection systems and firewalls provides a frontline defense; together with access control policies and encryption, they serve to mitigate these threats. For example, firewall logs are instrumental in detecting suspicious activities, such as repetitive failed login attempts or unusual traffic patterns.

Furthermore, weak password policies and sharing credentials amplify vulnerabilities, underscoring the need for enforceable password complexity requirements and periodic credential updates.

Risk Assessment and Mitigation Strategies

Applying the NIST risk management framework, threats are paired with vulnerabilities to estimate the likelihood and potential impact of exploitation. For example, the use of compromised credentials in the OPM breach indicates a high likelihood of insider threat exploitation, with severe implications for data confidentiality and operations continuity.

Mitigation strategies include implementing multi-factor authentication (MFA), conducting regular employee security awareness training, enforcing strict access controls, and deploying real-time monitoring tools. Encryption protocols must be applied consistently, and incidents should trigger automated alerts for rapid response.

A cost-benefit analysis suggests investing in advanced security controls yields a significant return by preventing costly breaches, reputational damage, and legal liabilities. The development of a comprehensive Plan of Actions & Milestones (POA&Ms) ensures systematic remediation is maintained and periodically reviewed for effectiveness.

Conclusion

The security landscape demands a layered, proactive approach combining technological controls, policy enforcement, employee training, and continuous monitoring. The OPM breach serves as a stark reminder of vulnerabilities arising from inadequate credential management, insufficient auditing, and weak boundary defenses. By adopting best practices from standards such as NIST SP 800-41 and SP 800-30, organizations can establish resilient cybersecurity frameworks, reducing the risk of similar breaches and safeguarding sensitive information assets.
