In 2023, the Canadian Border Services Agency (CBSA) was one of several federal departments hit by a wave of cyber-attacks, affecting kiosks and electronic gates at airports and delaying millions of travellers across the country. The result of a widespread targeted attack against Canadian entities, this was the first time threat analysts had seen a DDoS (Distributed Denial of Service) attack impact more than just a website—highlighting the crippling effect these incidents can have on organizations and on critical public systems.
As cybercriminals increasingly leverage artificial intelligence (AI) to deploy these types of attacks, the cyber security industry is beginning to explore how AI might complement existing methods, and that is the intention of this article, which aims to provide insights into that evolving landscape. Beyond that, it’s also important to approach this topic realistically, recognizing both the potential and the limitations of AI in DDoS mitigation. In this article, we’ll explore how AI could enhance cyber security, the challenges it faces, and why a layered approach that combines traditional solutions remains essential in defending against these attacks.
What Is A DDoS Attack?
A DDoS attack occurs when multiple internet-connected devices controlled by cybercriminals send a large amount of data or requests to an online service or website all at once. The goal is to overload the system, making it slow down or crash altogether so legitimate users can’t access it. This kind of cyber-attack can involve hundreds or thousands of devices across the internet.
The Growing Impact of DDoS Attacks
Over the past year, DDoS attacks have risen 106%. These increases caused the Government of Canada to issue a public alert following a series of DDoS attacks affecting various sectors, some of which targeted high-profile organizations, including the CBSA, Canadian Armed Forces, and Parliament.
The impact of DDoS attacks can range from temporary disruptions in service to prolonged downtime that could affect your business operations, revenue, and customer trust. Research shows the average DDoS attack lasts 68 minutes and costs organizations roughly $6,000 per minute—potentially leaving a $408,000 bill and a disruptive mess in its wake.
Traditional Methods for Mitigating DDoS
Traditional DDoS mitigation techniques are proven to focus on preventing or reducing the impact of attacks by filtering out malicious traffic and absorbing or dispersing the flood of incoming requests. Here’s an overview of proven approaches:
- Traffic Analysis and Filtering: Network traffic analysis involves analyzing incoming traffic to distinguish between legitimate and malicious requests. By setting thresholds for normal traffic, mitigation systems can filter out anomalies.
- Blackholing and Sinkholing: In blackholing, all traffic to the attacked IP address is redirected to a “black hole” where it is discarded. Sinkholing directs traffic to a valid IP address where the traffic can be analyzed and then filtered.
- Content Delivery Networks (CDNs): CDNs can mitigate DDoS attacks by distributing the load across multiple geographically dispersed servers, making it more difficult for an attack to significantly impact the service.
- Rate Limiting: Rate limiting controls the number of incoming requests a server can handle, preventing the server from becoming overwhelmed and ensuring availability.
- Anomaly Detection: Using statistical analysis, predefined thresholds, and machine learning, anomaly detection systems monitor network traffic and spot unusual patterns that may indicate a DDoS attack.
These established strategies remain foundational in protecting against DDoS attacks and provide reliable defences for businesses today.
The Evolving Role of AI in Cyber Security
AI is often discussed as a complementary tool in the fight against DDoS attacks. While it has the potential to enhance certain aspects of cyber security, its capabilities must be understood within the broader context of traditional methods. Here are some ways AI could contribute:
- Enhanced Detection and Response: AI algorithms analyze massive amounts of network data quickly, helping identify unusual patterns or anomalies that could signify an attack.
- Dynamic Adaptation: AI-driven systems can adjust defensive measures in response to evolving attack tactics.
- Support for Decision-Making: By reducing the volume of data that cyber security teams need to sift through, AI can assist in identifying critical threats more efficiently.
While AI offers promising advancements in DDoS mitigation, it’s not a standalone solution. Businesses must pair AI with proven traditional methods for a comprehensive defence.
Challenges in Using AI for DDoS Mitigation
Despite its potential, AI has its limitations and challenges when applied to DDoS mitigation. From technical complexities to evolving threats, recognizing and navigating these hurdles is an important first step if your organization is considering implementing AI in your cyber security strategy:
Technical Challenges:
- Data Quality and Quantity: Effective AI models require massive, high-quality datasets. Poor data quality can impair the training of AI models, leading to less effective cyber security measures.
- Algorithm Complexity: Crafting efficient AI models involves complex algorithm design. These models must balance accuracy, processing speed, and resource consumption, which can be difficult to achieve—especially in real-time attack scenarios.
- Evolving Threats: Cyber threats constantly evolve, making it challenging to keep AI models up-to-date with the latest attack patterns. This requires continuous learning and adaptation, which can be resource-intensive.
- Integration with Existing Systems: Implementing AI solutions often involves integrating them with existing—and sometimes outdated—IT infrastructure. This integration can be complex and costly.
Operational Challenges:
- Resource Allocation: Deploying and maintaining AI-based cyber security systems can be costly and resource-intensive. This includes both the computing resources needed to run the systems, the financial investment required to implement them, and also the significant expertise and the ongoing necessity for human oversight to avoid errors.
- Skills Gap: With AI advancing so quickly, the skills gap in the market is widening. Managing and developing AI-driven cyber security solutions requires expertise and deep knowledge, which make it challenging to find people who qualify.
- False Positives and Negatives: AI systems can sometimes make incorrect decisions, misidentifying benign activities as threats (false positives) or failing to detect actual attacks (false negatives). This could lead to potentially damaging outcomes for your business.
- Scalability: As network environments grow in size and complexity, ensuring that AI solutions can manage larger data volumes and maintain performance is challenging.
The reality is that, like any cyber security solution, AI alone cannot protect your organization. Having an awareness of these challenges early on is key, as it will guide you in developing a layered approach to DDoS mitigation and contingency response plans for a comprehensive and 360-degree approach to your cyber security strategy—one that combines the reliability of proven solutions with the potential of emerging technologies.
Practical Insights for Organizations
Organizations considering AI adoption should approach it strategically:
- Assess Current Security Posture: Identify areas where AI could add value within your existing defences.
- Select Suitable Solutions: Evaluate AI-powered tools that align with your organization’s needs while ensuring compatibility with your current systems.
- Adopt a Proactive Approach: Conduct regular security audits, train employees, and maintain a layered defence strategy.
The Case for Combining Traditional and AI-Powered Defences
Traditional methods and AI each have strengths and limitations, but together they offer a comprehensive defence against DDoS attacks. Consider the following:
Traditional DDoS Prevention:
- Pros: Effective against simple attacks, cost-efficient.
- Cons: May struggle with sophisticated attacks and generate false positives.
AI-Powered DDoS Prevention:
- Pros: Can analyze large datasets in real-time and adapt to new threats.
- Cons: Expensive, requires expertise, and depends on high-quality data.
Since each approach has its own strengths and limitations, combining them provides a balanced solution that leverages the reliability of traditional defences and the advanced capabilities of AI. This combination strengthens overall security by enhancing threat detection, improving response times, and providing a layered approach to protect against both known and emerging threats.
