The Quick Finance Company network, characterized by its limited security infrastructure and small scale, presents numerous vulnerabilities that can be exploited by malicious actors. Given the absence of detailed information about the network infrastructure, making assumptions becomes essential to identify potential vulnerabilities and craft appropriate mitigation techniques. This analysis assumes that the network comprises a combination of wired and wireless components, with centralized servers hosting sensitive data, and employs basic firewall protections without additional security layers such as intrusion detection or multi-factor authentication.

One primary assumption is that the company's web and VPN servers are accessible via the internet with minimal security controls, exposing them to common threats like defacement, session hijacking, and service Denial-of-Service (DoS) attacks. It is also presumed that the employee workstations and databases lack rigorous access controls, encryption, and regular security updates. The absence of a dedicated security professional suggests that security policies are either outdated or nonexistent, increasing vulnerability to exploitation.

Analyzing each access point reveals significant protection gaps. For example, the web server, which has already been defaced twice, indicates weak defenses—possibly unpatched software or lack of web application firewalls. The VPN server, handling remote access, is susceptible to session hijacking and DoS attacks, suggesting insufficient encryption or session management protocols. Network segments such as the employee workstations and database servers may rely solely on basic network segmentation without additional safeguards like VPNs or proper access controls, leaving internal resources vulnerable to lateral movement in case of compromise.

The vulnerabilities stemming from this network design are manifold. The lack of enforced password policies and absence of multi-factor authentication make user accounts easy targets for credential theft. Outdated or misconfigured web and VPN servers facilitate defacement and hijacking attempts. The company's minimal security posture, with no dedicated security personnel, hampers proactive threat detection and incident response. Moreover, insufficient network segmentation allows attackers to move laterally within the network post-entry, increasing the risk of data breaches and operational disruptions.

Ranking the top three most probable network-based attacks involves assessing likelihood based on historical trends and system vulnerabilities. First, web server attacks, such as defacement and exploitation of web application vulnerabilities, are most likely due to previous defacements and unpatched systems. Countermeasures include regularly patching web applications, deploying web application firewalls, and monitoring server logs for suspicious activities. Second, session hijacking targeting the VPN server is probable, especially if session encryption and token management are weak; implementing multi-factor authentication and secure session protocols can mitigate this risk. Third, DoS attacks on the VPN server or web server are plausible, considering their exposure; to counter these, deploying Intrusion Detection Systems (IDS) and anomaly detection can identify and block attack traffic early.

To reduce or eliminate business interruptions, the organization should adopt comprehensive mitigation procedures. These include implementing robust password policies, enforcing multi-factor authentication, and ensuring all servers and software are regularly patched and updated. Network segmentation should be improved by isolating sensitive systems and critical resources, limiting the attack surface. Deploying intrusion detection and prevention systems will provide real-time monitoring and response capabilities against threats like DoS and unauthorized access. Employee training on cybersecurity best practices and establishing incident response plans are also crucial to improve resilience against attacks. Regular security audits and vulnerability assessments will help identify emerging threats early, enabling prompt remediation.

Utilizing credible sources such as the National Institute of Standards and Technology (NIST), cybersecurity frameworks, and scholarly articles provides a foundation for these recommendations. NIST's Cybersecurity Framework emphasizes the importance of identify, protect, detect, respond, and recover functions, aligning with the mitigation strategies suggested. Research indicates that small organizations lacking dedicated security staff are particularly vulnerable and should adopt layered security approaches, including regular patches, segmentation, and monitoring (NIST, 2018). Drawing from OWASP guidelines, web application security and proper session management are critical to prevent defacement and hijacking (OWASP, 2020). Additionally, studies show that employee training significantly reduces successful phishing attacks and credential theft (Verizon, 2021).
