What Is AI Threat Detection?

The Evolution of Threat Detection

For decades, threat detection has mainly worked by using a signature-based system for detecting threats. Known threats are cataloged by industry professionals and shared in public databases like the MITRE ATT&CK Framework. These frameworks would show businesses the exact signatures to look out for, allowing them to then identify attacks in their early stages by recognizing elements of their signature.

Several core technologies, like Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR) solutions, used signature identification to locate threats. If one of these tools detected a signature commonly associated with a threat vector, they would alert the cybersecurity team and begin to isolate the threat.

But with the arrival of AI, threats can now rapidly morph, obfuscating their previous signatures and challenging EDR and XDR solutions. The integration of AI tools into the cybersecurity stack that uses behavioral analysis, pattern tracing, and anomaly detection helps to identify these threats, even in zero day scenarios.

To keep up with the changing form attacks can take, more businesses than ever are turning to AI solutions to augment their existing security controls.

Key Technologies in AI Threat Detection

AI threat detection uses a range of different technologies in tandem to identify distinct threats. Some components will scan for known attack vectors, like in earlier EDR and XDR solutions. Other components will use AI components to learn from public attack data and understand new threat vectors in real time.

Here are some of the main technologies that enable AI threat detection:

• • Machine Learning (ML): Machine learning is the ability of artificial intelligence models to learn from previous data to continually improve and refine their offerings. In threat detection, ML allows models to understand historical attack data, identify new threat vectors, and continually become better at understanding malicious attacks.
  • Behavioral Analysis: AI technology can process enormous volumes of user data at once to better understand how they behave when connected to a company account. If an account suddenly interacts with company systems in a strange or unexpected way, this can trigger a behavioral alert that blocks the account to prevent account hijacking.
  • Natural Language Processing: Threats like phishing emails are still a leading method that malicious entities use to deliver malware into businesses. By using NLP, AI can process emails and better understand their contextual intent, identifying potential markers that signal an email may contain phishing elements and blocking them.

• Threat Intelligence Knowledge Building: Artificial intelligence software scrapes data from leading cybersecurity threat vector frameworks to continually update itself on different emerging types of threats. The continual use of research and expanding its known corpus of threat markers allows AI tools to readily understand and respond to threats. Drawing from thousands of distributed knowledge bases allows AI tools to respond in real-time to novel threats, improving zero day detection capabilities.

• Automated Threat Response: Leading AI cybersecurity software uses a range of automatic pathways to respond to threats in real time. The availability of these pathways allows AI tools to instantly respond in the best possible way to a threat, isolating it, reducing its visibility, and alerting security teams that a breach may be occurring. 

The Need for AI Threat Detection

Malicious actors are increasingly using artificial intelligence to improve their attacks and make threat vectors more challenging to detect. AI threat detection is the direct answer to these evolving threats, providing an around-the-clock method of identifying and preventing these attacks from impacting your business.

There are a number of benefits of AI threat detection:

• Automatic Threat Response: AI tools can work 24/7/365 to scan for potentially malicious entities in your system and neutralize them as quickly as possible. This comprehensive automatic solution allows you to scale your business without worrying about a lack of cybersecurity visibility. 
• Improve Cybersecurity Workflows: When AI tools actively monitor a company’s attack surface for threats, this frees up a significant amount of time for cybersecurity teams. These teams can then better spend their time elsewhere, conducting penetration tests and fortifying a company’s cyber defenses instead of just monitoring for threats.
• Combats Advanced Threats: As malicious actors develop more challenging technology, often itself enabled by AI software, businesses must turn to AI tools to identify and defend against advanced threat vectors. 

Types of Cyber Threats Detected by AI

Artificial intelligence tools can detect any existing threat that other cybersecurity defense tools monitor for. This means that classic threats like phishing and spear-phishing attacks, as well as common types of malware and DDoS attacks, are all recognized by AI. 

Alongside the more standard cyber threats, AI can also detect:

• Zero day vulnerabilities
• Wider supply chain attacks
• Account hijacking and insider threats

How to Implement AI in Existing Security Frameworks

Artificial intelligence tools aren’t a complete infrastructural shift in the cybersecurity world. On the contrary, they typically support existing tools and integrate where possible to streamline your security architecture.

Here are the steps you should follow to successfully integrate AI into your existing cybersecurity posture:

1. Evaluate Your Current Landscape: Take stock of all the technologies you currently use in your security posture and note where AI could improve your defenses or streamline internal workflows.
2. Select and Train Your AI Tool: Select an effective AI cybersecurity tool with a proven track record. Businesses can then train their tool on internal data to refine it and fulfill the exact objective you’ve defined in step one.
3. Test AI Models and Integrate: In sandbox conditions, test your AI model with a number of fabricated threats to see how it performs. If necessary, continue to refine your model until it is able to detect and respond to the exact kinds of threats that you expect it to cover in your security posture. Once ready, you can then integrate these models into your system.

Monitor Performance and Improve: Continually monitor your AI cybersecurity models and feed them additional data to improve their performance. Where possible, integrate available threat intelligence data to increase the scope of your AI model. Always include a human-in-the-loop during these processes to oversee your AI system and ensure it acts as expected.
