In the context of cybersecurity for critical infrastructure such as a small airport, developing a robust Risk Management Plan (RMP) is essential to safeguard sensitive assets against escalating threats. The absence of a previous comprehensive security management plan necessitates a structured approach to identify assets, assess threats, and implement effective controls. This paper details the creation of such a plan, explicitly focusing on assets relevant to the airport's web and application infrastructure, threat assessment, and strategic recommendations for mitigating high-risk vulnerabilities.
**Asset Identification and Valuation**
The first step involves cataloging and valuing the assets that comprise the airport's digital infrastructure within the scope of this assessment. A comprehensive Asset Register is crucial for understanding what needs protection and for prioritizing security efforts. Table 1 illustrates the minimum six assets identified, emphasizing their categories, valuation, and existing controls.

The assets, ranging from operational systems to customer-facing applications, are critical to airport operations. Their valuation underscores the importance of implementing tailored controls to mitigate vulnerabilities.
The next phase involves analyzing each asset concerning potential threats, assessing likelihood, and the impact (gravity). This process results in a Threat Assessment Table (Table 2). The likelihood and gravity are rated on a scale of Low, Medium, and High based on industry threat intelligence and local context.

The prioritized threats reveal that external-facing systems like the public website and employee login portal are highly exposed to cyberattacks such as DDoS, phishing, and malware infiltration. The passenger database and payment systems are attractive targets for data breaches and financial exploitation, demanding heightened security measures.
**Recommendations and High-Risk Areas**
Based on the threat assessment, the following recommendations are proposed:
1. **Enhance Web Application Security:**
- Implement Web Application Firewalls (WAFs) to filter malicious traffic.
- Conduct regular vulnerability scans and penetration tests.
- Enforce secure coding practices to prevent SQL injection and cross-site scripting (XSS).
2. **Strengthen Authentication and Access Controls:**
- Deploy multi-factor authentication (MFA) across all systems.
- Regularly review user access privileges and remove unnecessary permissions.
- Implement role-based access control (RBAC) to limit exposure.
3. **Data Protection Measures:**
- Encrypt sensitive data at rest and in transit.
- Establish rigorous backup and recovery procedures.
- Use data masking and tokenization where applicable.
4. **Incident Response and Monitoring:**
- Develop and regularly update an incident response plan.
- Use intrusion detection and prevention systems (IDPS) to monitor threats.
- Conduct security awareness training for employees to recognize and respond to phishing and social engineering attacks.
5. **Infrastructure Segmentation and Hardening:**
- Isolate critical systems such as air traffic management from less secure networks.
- Regularly patch and update all systems to fix vulnerabilities.
- Limit physical access to data centers and network hardware.
6. **Policy Development and Compliance:**
- Establish standardized security policies aligned with industry standards like ISO 27001 and NIST.
- Conduct periodic compliance audits and risk assessments.
- Maintain documentation for accountability and continuous improvement.
**Conclusion**
The security landscape for a small airport's web and application infrastructure necessitates a proactive, layered security approach. By identifying key assets, assessing threats, and implementing targeted controls, the airport can significantly reduce its vulnerability footprint. Ongoing monitoring and periodic reassessment are vital to adapt to evolving threats. The above recommendations provide a strategic framework that aligns with best practices in cybersecurity risk management, ensuring the integrity, availability, and confidentiality of critical systems and data.
