Paper For Above instruction

The network environment of Global Finance, Inc. (GFI) has experienced rapid growth, resulting in a complex and interconnected infrastructure that is vital to the company’s operations. The network diagram depicts multiple interconnected devices, including routers, switches, firewalls, and servers, designed to provide fault tolerance and resilience. These components facilitate communication both internally among company departments and externally with clients and financial institutions. The core of the network is built upon a trusted computing base hosting mission-critical systems, such as the Oracle database and email servers, which are crucial to GFI’s ability to operate smoothly and securely.

The communication environment at GFI spans multiple network segments, interconnected via routers and switches to form a layered architecture. The internal network is segmented into zones—private, demilitarized zone (DMZ), and internet-facing perimeter—implemented to enhance security and control traffic flows. This segmentation aligns with industry best practices to contain breaches and limit lateral movement of threats. Firewalls and intrusion detection systems (IDS) are strategically placed to monitor and control network traffic. External connections, including remote access and cloud-based services, extend the network perimeter, further increasing potential attack vectors.

Risk assessment of the GFI network revolves around identifying vulnerabilities that could lead to service disruptions, data breaches, or financial loss. The scenario highlights issues such as exposure to distributed denial-of-service (DDoS) attacks, insufficient security personnel, and the existing reliance on perimeter defenses without robust internal security measures. The recent DDoS attacks, which caused Oracle and email servers to be offline for a week, have resulted in an estimated loss exceeding $1 million and caused damage to customer confidence. This underscores the necessity of a comprehensive risk strategy that encompasses prevention, detection, and response mechanisms.

Assessing vulnerabilities involves scrutinizing network design, configurations, and implemented security controls. Three key vulnerabilities emerge from the scenario:

1. Lack of Internal Segmentation and Insufficient Access Controls

The internal network hosts mission-critical systems within a trusted computing base, yet there appears to be limited segmentation within this environment. Without proper internal segmentation, a breach compromising one system could allow lateral movement across the network, amplifying the potential damage. Furthermore, inadequate access controls—such as weak authentication or broad permissions—may enable unauthorized personnel or malicious actors to exploit sensitive systems.

Mitigation strategies include implementing stricter network segmentation, employing zoned architecture with firewall policies regulating communication between segments. Additionally, deploying multi-factor authentication (MFA) and least-privilege access controls can minimize insider and outsider threats.

2. Insufficient Defense Against DDoS Attacks

The company’s experience with DDoS attacks points to a vulnerability in its perimeter defense. Relying solely on traditional firewalls and perimeter security measures is insufficient against volumetric attacks designed to overwhelm resources. The lack of scalable DDoS mitigation solutions exposes GFI to repeated service outages, risking operational continuity and reputation.

Recommended mitigation includes deploying dedicated DDoS mitigation services, such as cloud-based scrubbing centers, and configuring network appliances to detect and block abnormal traffic patterns. Rate limiting and traffic filtering should be implemented to reduce attack surface and maintain service availability during attack incidents.

3. Absence of Robust Security Monitoring and Incident Response

The scenario indicates a lack of dedicated security personnel and continuous monitoring capabilities. Without real-time detection and rapid response plans, GFI risks prolonged breaches or attack impacts. The recent recovery costs and operational downtime highlight the significance of proactive security monitoring.

Implementing Security Information and Event Management (SIEM) systems, along with automated alerting and incident response protocols, can significantly improve detection and containment capabilities. Regular security audits and penetration testing further strengthen the defense posture.

Cryptography recommendations are rooted in protecting data confidentiality and ensuring the integrity and authenticity of communications. For internal and external data exchanges, implementing Transport Layer Security (TLS) protocols with strong cipher suites (e.g., AES-256, RSA-2048) ensures secure transmission. Data encryption at rest, using robust algorithms like AES-256, should be applied to sensitive databases and storage devices. Digital signatures and public key infrastructure (PKI) facilitate secure authentication and non-repudiation, which are vital given the company's financial importance.

The risk assessment methodology employed combines qualitative and quantitative approaches. Qualitative methods evaluate the likelihood and impact of identified risks based on expert judgment, while quantitative analysis estimates potential financial losses and probability metrics. This hybrid approach enables a comprehensive understanding, allowing prioritization of vulnerabilities according to their potential impact and likelihood. Quantitative analysis concretizes the assessment by translating risks into dollar estimates, supporting data-driven decision-making.

To effectively communicate findings, I recommend presenting a clear executive summary that highlights key vulnerabilities, risks, and recommendations. Visual aids, such as risk matrices, threat maps, and the redesigned network architecture diagram, will facilitate comprehension among management. Demonstrating the cost-benefit analysis of proposed mitigations—such as investment in DDoS mitigation services or internal segmentation—will enhance buy-in. Presenting a prioritized action plan aligned with business objectives underscores how security improvements directly support operational resilience and confidence.

The reimagined secure network model, depicted in the diagram, consolidates security best practices and mitigation controls. It incorporates segmented zones with firewalls, dedicated DDoS mitigation filters at the perimeter, and centralized security monitoring systems. Encryption controls encrypt sensitive data, and layered defenses ensure redundancy. The diagram emphasizes a security-by-design approach, where defenses are integrated into the network architecture rather than added ad hoc, significantly reducing attack surfaces and vulnerabilities.

In conclusion, GFI’s rapid growth and network expansion have exposed its infrastructure to various security vulnerabilities. A comprehensive risk assessment that combines technical, procedural, and managerial controls is imperative to safeguard critical financial systems. Prioritizing internal segmentation, enhancing DDoS defenses, and establishing continuous monitoring will considerably strengthen GFI’s security posture. Employing a hybrid risk assessment methodology ensures effectiveness and precision, supporting strategic decision-making. Effective communication with management through clear, visual, and data-supported presentations will facilitate security buy-in and foster an organizational culture of security resilience.
