Protecting Airports From Ddos Attacks: A Comprehensive Guide

Distributed Denial of Service (DDoS) attacks are a type of cyber attack that aims to overwhelm a targeted system with a flood of traffic. Airports are a common target for these attacks as they are critical infrastructure and often seen as representatives of a state or region. In recent years, there have been several high-profile DDoS attacks on airport websites, causing temporary disruptions and affecting passengers' ability to access services and receive updates. As airports rely heavily on their websites and online services, it is crucial to implement effective strategies to safeguard against such attacks. This involves identifying assets, conducting risk assessments, improving security, and monitoring for potential threats.

Identify assets and conduct a business impact analysis

To protect against DDoS attacks, airports must first identify their assets and conduct a business impact analysis. This involves cataloguing all assets exposed to the internet and determining their criticality to business operations.

Identify Assets

Airports should identify their resources that are accessible over the internet. This includes websites, application programming interfaces (APIs), applications, virtual private networks (VPNs), and more.

Conduct a Business Impact Analysis

This analysis evaluates the impact of an internet outage at the airport level. Airports rely on cloud apps for many processes, so a DDoS attack causing an internet disruption can have significant consequences.

The impact of a DDoS attack on an airport's operations can be assessed by considering the following:

• Revenue generation: The financial impact of potential flight cancellations, passenger delays, and disruptions to other airport services.
• Customer impact: The inconvenience and dissatisfaction caused to passengers, potentially affecting the airport's reputation and future business.
• Operational significance: The extent to which the targeted asset contributes to the airport's overall operations and efficiency.

By understanding the potential impact of a DDoS attack on each asset, airports can prioritize their defence strategies and allocate resources effectively.

Subscribe to a Web Application and API Protection service

Distributed Denial of Service (DDoS) attacks are a significant threat to airports, as they are critical infrastructure and representatives of a state or region. To safeguard against such attacks, airports need to implement robust cybersecurity measures that protect their websites, information systems, and infrastructure.

One crucial recommendation for airports to enhance their cyber resilience is to subscribe to a "Web Application and API Protection" service. This service provides a comprehensive solution to protect web applications and APIs from DDoS attacks. Here are some key features and benefits of subscribing to such a service:

• Cloud-Based Solution: The easiest and most recommended option for airports is to opt for a cloud-based protection service. Cloud-based solutions are generally easier to deploy and can provide effective security without the need for on-premise hardware. They also often come with built-in anti-DDoS protection, simplifying the process for airports.

They analyze network traffic to distinguish between normal traffic and attack traffic, allowing for quick response and mitigation. This detection capability is crucial in stopping or minimizing the impact of DDoS attacks.
• API Security: APIs (Application Programming Interfaces) are a common target for DDoS attacks. A Web Application and API Protection service will secure APIs by implementing measures such as rate limiting, which controls the number of requests an API can receive within a specific timeframe. This helps prevent APIs from being overwhelmed by excessive requests during a DDoS attack.
• Web Application Firewall (WAF): A WAF acts as a firewall specifically designed to protect web applications. It allows or blocks network requests and responses based on predefined rules, helping to prevent vulnerability exploits and blocking requests from suspicious IP addresses. This adds an extra layer of protection for web applications.
• Automated Updates and Self-Tuning: Reputable protection services offer automated updates, ensuring that the security measures are always up to date with the latest threat intelligence. Additionally, self-tuning capabilities eliminate the need for manual patching, saving time and effort for security teams.
• Integration and Compatibility: Look for a protection service that integrates well with your existing systems and can be customized to your specific needs. Some services offer DevOps integration, allowing for seamless deployment within a CI/CD pipeline. This ensures that security is maintained throughout the development and application lifecycle.
• Threat Intelligence: A good protection service will provide threat intelligence capabilities, allowing airports to stay ahead of potential attacks. This includes monitoring channels where cyberattackers may announce their intended targets, giving airports an early warning to prepare their defenses.
• Support and Management: Opt for a service that provides adequate support and management options. Some services offer fully managed, co-managed, or self-service support levels to suit your airport's specific requirements and internal capabilities.

By subscribing to a Web Application and API Protection service, airports can significantly enhance their defenses against DDoS attacks. It is crucial to select a reputable service provider with a proven track record in protecting against evolving cyber threats.

Diversify hosting providers

Airports should consider diversifying their hosting providers to enhance their defence against DDoS attacks. By using multiple cloud providers, airports can benefit from built-in anti-DDoS protection and increase their cyber resilience. This strategy is recommended by Eric Vautier, the Chief Information Security Officer of Groupe ADP, who emphasises the importance of not putting "all your eggs in the same basket".

Having multiple hosting providers adds an extra layer of security and complexity for potential attackers. It also provides airports with greater flexibility and control over their web services. By leveraging the capabilities of different cloud providers, airports can improve their overall cyber defence posture.

For example, an airport can choose a cloud provider that offers advanced DDoS protection services, such as real-time monitoring of all network traffic, 24/7/365 technical support, and integration with content delivery networks (CDNs) like Cloudflare. CDNs, in particular, can play a crucial role in DDoS defence by filtering out malicious traffic closer to its source, ensuring optimal website performance even during an attack.

Additionally, diversifying hosting providers can help airports maintain operations and minimise disruptions in the event of a successful DDoS attack. If one provider is compromised, the airport can rely on other providers to keep essential web services online. This redundancy can be crucial in ensuring that travellers, airlines, and airport personnel can still access critical information and services.

However, it is important to note that managing multiple hosting providers can introduce complexities, especially when dealing with interconnected systems. Airports should carefully evaluate the trade-offs between security, cost, and operational complexity when diversifying their hosting providers.

Start a Cyber Threat Intelligence (CTI) program

Distributed Denial of Service (DDoS) attacks are a type of cyber attack that aims to overwhelm a targeted system with a flood of traffic. Airports are often the target of such attacks as they are critical infrastructure and representative of a state or region.

To protect against DDoS attacks, airports can implement a Cyber Threat Intelligence (CTI) program. Here are some steps to start a comprehensive CTI program:

• Define the Scope and Objectives: Understand the specific threats and vulnerabilities the program will address, such as phishing attacks, malware, or advanced persistent threats. Set clear objectives, such as increasing the speed of detecting and mitigating new threats.
• Develop a Collection and Analysis Plan: Identify various threat intelligence sources, including open-source information, industry reports, and intelligence from other organizations. Establish a process for analyzing and disseminating intelligence efficiently and effectively, prioritizing it based on relevance and potential impact.
• Establish a Process for Analysis and Dissemination: Identify key stakeholders, such as the security team, IT staff, and other relevant departments. Decide on the format and channels for delivering intelligence, such as email alerts, periodic reports, or dashboards, ensuring it is accessible and actionable for stakeholders.
