Develop an analysis of the security of a cyber-system (DTS) utilizing the 1st five SANS Critical Security Controls methodology. During this research project, perform a security analysis of the Defense Travel System (DTS) by utilizing the SANS first 5 Critical Security Controls methodology. The controls to be covered include:

  • Inventory of Authorized and Unauthorized Devices
  • Inventory of Authorized and Unauthorized Software
  • Secure Configurations for Hardware and Software on Mobile Devices, Laptops, Workstations, and Servers
  • Continuous Vulnerability Assessment and Remediation
  • Malware Defenses

The system overview describes DTS as a web-based platform providing automated trip support services for DoD agencies and military services, involving various functions such as travel planning, data management, compliance enforcement, digital signatures, financial computations, external interfaces, and official document archiving. The system utilizes Java applets and the DoD PKI for secure login via Common Access Cards, serving approximately 165,000 personnel daily. DTS supports secure, remote access for travel authorization, reservation, and approval processes, with interfaces to external systems.

Paper For Above instruction

The Defense Travel System (DTS) is a critical component of the Department of Defense’s (DoD) operational infrastructure, facilitating automated, secure travel management for approximately 165,000 military and civilian personnel daily. Given its expansive user base and sensitive data, assessing its cybersecurity posture through the lens of the first five SANS Critical Security Controls provides a strategic approach to identify vulnerabilities and enhance its security resilience.

1. Inventory of Authorized and Unauthorized Devices

The foundation of any cybersecurity strategy is a comprehensive inventory of all devices connected to the network. For DTS, this entails cataloging all approved mobile devices, laptops, servers, and workstations authorized to access the travel system. Implementing automated Asset Management Tools ensures continuous monitoring and scanning to detect unauthorized devices. These tools can employ network access controls (NAC) and endpoint detection techniques to prevent rogue devices from infiltrating the system, thus reducing the risk of unauthorized access and potential data breaches (Scarfone & Mell, 2007).

2. Inventory of Authorized and Unauthorized Software

Keeping an up-to-date inventory of authorized software is essential for maintaining system integrity. DTS developers and administrators should utilize application whitelisting solutions, such as Microsoft AppLocker or third-party endpoint security tools, to prevent installation or execution of unauthorized applications. Regular audits and automated scans can detect any unapproved software, which may serve as vectors for malware or exploits (Harrison, 2014). Furthermore, maintaining a strict update and patching schedule for approved software minimizes vulnerabilities arising from outdated versions.

3. Secure Configurations for Hardware and Software on Mobile Devices, Laptops, Workstations, and Servers

Secure baseline configurations are critical in preventing exploitation. For DTS, this involves configuring all hardware and OS instances according to established security standards, such as those outlined by the National Institute of Standards and Technology (NIST). This includes disabling unnecessary services, enabling firewalls, enforcing strong password policies, and encrypting data at rest and in transit (NIST, 2018). Regular configuration audits ensure compliance with security protocols, thereby reducing the attack surface for cyber threats.

4. Continuous Vulnerability Assessment and Remediation

The dynamic landscape of cyber threats necessitates ongoing vulnerability assessments. Tools like Nessus or Qualys can perform regular scans of the DTS infrastructure to identify vulnerabilities in software, hardware, and network configurations. Prompt remediation—applying patches, updating configurations, and removing vulnerabilities—is crucial to prevent exploitation. Automating vulnerability management processes accelerates detection and response, maintaining the integrity of DTS (Cosecure, 2019).

5. Malware Defenses

Deploying robust malware defense mechanisms such as antivirus, anti-malware solutions, and intrusion detection systems (IDS) are vital. These defenses must be configured to detect, quarantine, and remove malicious code effectively. Regular updates of malware signatures and heuristic analysis ensure defenses adapt to emerging threats. In addition, user training on phishing and social engineering enhances overall security posture by reducing the likelihood of malware infiltration through user error (SANS Institute, 2020).

Challenges and Recommendations

The security analysis of DTS highlights challenges such as maintaining up-to-date inventories in a rapidly evolving environment, ensuring all configurations and patches are current, and training personnel effectively. To mitigate these risks, continuous monitoring, automated patch management, comprehensive user awareness programs, and strict access controls are recommended. Additionally, integrating threat intelligence feeds can enhance detection capabilities against emerging cyber threats, ensuring DTS remains resilient against cyber attacks.

Conclusion

Applying the first five SANS Critical Security Controls provides a structured methodology to improve the cybersecurity posture of the Defense Travel System. By establishing rigorous device and software inventories, enforcing secure configurations, conducting ongoing vulnerability assessments, and deploying effective malware defenses, DTS can significantly mitigate its cyber risks. As cyber threats continue to evolve, maintaining this proactive security stance is imperative to protect sensitive travel data and ensure uninterrupted service to the Department of Defense.
