The evolution of cyber threats and the increasing complexity of IT and DevSecOps environments drive the need for innovative defence strategies. Automated vulnerability discovery and AI-driven defensive tools transform the cybersecurity landscape, enabling defenders to detect and mitigate attacks with unprecedented speed and precision. This shift is crucial because attackers leverage automation and AI to accelerate their efforts. To remain effective, defenders must adopt AI across various defensive applications.
This blog explores the critical need for AI adoption in cybersecurity. It outlines the importance of developing a standardized “Defender’s Framework” to guide organizations in approaching these emerging technologies.
The Case for AI-Driven Defence
AI-driven defence mechanisms are expected to alter cybersecurity radically over the next 6–18 months. With the rise of automated tools for vulnerability discovery and attack detection, defenders now have access to faster and more comprehensive insights into their environments. These advancements enable real-time threat detection, dynamic response strategies, and ongoing system health monitoring. Key applications of AI in defensive cybersecurity include:
1. SOC Analyst Augmentation
AI tools assist Security Operations Centres (SOCs) by automating the triage process, flagging critical alerts, and reducing false positives. This frees human analysts to focus on more complex tasks, improving overall operational efficiency and response times.
2. Automated Continuous Penetration Testing
AI-based penetration testing continuously scans systems for vulnerabilities, simulating real-world attacks. This automation enables organizations to identify and fix vulnerabilities quickly, reducing the attack surface before malicious actors exploit them.
3. Automated Patching
Vulnerability management tools that leverage AI can automatically prioritize and apply patches based on the severity of vulnerabilities. This process reduces the risk of exposure by ensuring that patches are deployed swiftly across an organization’s infrastructure.
4. Compliance Observability (including Third-Party Risk Management, TPRM)
AI helps organizations maintain regulatory compliance by automating the monitoring of security controls and ensuring that third-party suppliers follow necessary security protocols. It enhances visibility and reduces the risk of supply chain attacks.
5. Insider Behavioural Analysis
AI-powered behavioural analysis tools can detect anomalous behaviour patterns in insider threats. Analyzing user activity in real-time allows these systems to identify suspicious actions before they escalate into breaches.
6. Supervision of Traditional ML Training Pipelines
Machine learning models can be vulnerable to adversarial attacks. AI-driven supervision tools monitor the training pipelines for potential biases, anomalies, or attacks, ensuring that the models are trained securely and continue functioning as intended.
Projects like Project Naptime and XBOW, alongside many successful private initiatives, highlight the growing impact of AI on vulnerability discovery. These tools allow for faster detection of potential threats, augment SOC operations, and streamline continuous penetration testing and automated patching.
Defender's Framework: A Taxonomy of Defence
A critical component of building robust AI-driven defences is the establishment of a comprehensive taxonomy of attacks and defences. This taxonomy will allow defenders to map specific defences to relevant attack types, creating a structured and targeted approach to mitigating threats. There are two main types of defences:
1. Pre-emptive Defences
These anticipate potential attacks and include traditional cybersecurity measures such as firewalls, intrusion detection systems, and network segmentation. AI enhances these defences by using predictive analytics to identify vulnerabilities before they can be exploited.
2. Post-Attack Defences
These are applied after an attack and focus on mitigating damage. An example is spatial smoothing applied to an adversarial sample, which reduces the attack’s impact and prevents further harm.
A well-developed Defender’s Framework should integrate these defences, ensuring that AI systems are protected before and after an attack. This framework will help organizations implement AI-driven tools effectively, maximizing their ability to defend against evolving threats.
Collaboration and Standardization
Developing a standardized Defender’s Framework should build upon established industry standards rather than starting from scratch. Several well-known frameworks are already widely used in the cybersecurity industry, including:
MITRE ATT&CK
A framework that describes attacker tactics, techniques, and procedures (TTPs) used in attacks against infrastructure and networks.
MITRE ATLAS
A framework specifically focusing on attacker TTPs targeting AI/ML systems.
CAPEC
A comprehensive catalogue of common attack patterns in application-layer security.
CWE and CVE
Frameworks used to describe known weaknesses and vulnerabilities.
Additionally, there are ontologies like MITRE D3FEND, which maps defences to specific technologies, and the MIT BRON ontology, which links the above frameworks with structured threat information exchange (STIX). These resources form a solid foundation for the Defender’s Framework.
Identifying and addressing gaps in these frameworks, particularly around AI safety and policy standardization, will be essential to ensuring widespread AI adoption in cybersecurity. Standardization in evaluation specifications will create a consistent and reliable method for testing the effectiveness of AI-driven defences.
The Importance of Workflow and Policy Standardization
Organizations must also focus on standardizing workflows and policy frameworks to implement AI-driven cybersecurity tools effectively. Standardized workflows streamline processes for evaluating, detecting, and responding to attacks, making defensive efforts more efficient. A unified policy language guiding decisions between workflow stages will ensure these AI-driven systems can be implemented across different platforms without vendor lock-in.
This interoperability is crucial for allowing organizations to adopt the best AI tools available, ensuring flexibility and scalability in their defensive strategies.
Leveraging Generative AI for Natural Language Processing
Generative AI (GenAI) can further enhance the effectiveness of the Defender’s Framework by introducing natural language processing (NLP) capabilities. GenAI can interpret and process large volumes of data, automating report generation, workflow orchestration, and policy evaluation.
For example, GenAI can simplify the interaction between security teams and AI/ML systems by allowing them to generate natural language queries. These queries could prompt reports on detected threats, evaluate the metrics of ML systems, or suggest policies based on specific criteria. This integration would make AI tools more accessible, particularly in large, complex organizations.
Conclusion
AI-driven defences, standardized frameworks, and workflows are essential for outpacing attackers in a complex and hostile cybersecurity landscape. Integrating AI into defensive operations, supported by a standardized Defender’s Framework, will allow organizations to deploy more adaptive, scalable, and effective cybersecurity practices.
By building a collaborative approach to standardization, including policy language and workflow orchestration, the cybersecurity community can ensure that AI-driven technologies are adopted efficiently and provide maximum value in safeguarding critical infrastructure and sensitive data.
