Bracing for the AI-Driven Cybersecurity Landscape of Tomorrow

Maria Markstedter, founder of Azeria Labs and security researcher specialized in mobile and IoT security, was the opening keynote at BlackHat 2023 — Guardians of the AI Era: Navigating the Cybersecurity Landscape of Tomorrow. Markstedter provided an enlightening look at how artificial intelligence will transform cybersecurity in the coming years. While AI brings many benefits, it also poses novel threats that developers must understand to secure their systems.

As Markstedter described, AI chatbots like ChatGPT have gone mainstream seemingly overnight. However, businesses have valid concerns about exposing sensitive data to these external services. In response, a new market for in-house AI development platforms has rapidly emerged.

This leads to a future where AI assistants have broad access to internal systems to increase productivity. However, autonomous decision-making capabilities raise significant security questions. Just as identity and access management secures human users, new safeguards are needed to secure AI agents.

Multi-modal AI that synthesizes data from images, text, voice, and more exponentially expands potential attack surfaces. Malicious instructions could lurk imperceptibly within any input channel. Securing AI systems will require holistic data validation and sanitization well beyond current practices.

Sergienko warns that AI could be exploited through automatically processing internet data. For example, an AI agent instructed to create a new app could download arbitrary code found online containing backdoors. The ability to ingest external data is fundamental but also dangerous.

A key challenge highlighted is that AI decision-making lacks transparency. The exact logic behind responses is often inscrutable even to the developers. This underscores the need for explainable AI that elucidates how conclusions are reached. Otherwise, detecting manipulated results or troubleshooting failures becomes impossible.

Markstedter emphasizes that while AI may not eliminate the need for security professionals, new skill sets will be in high demand. Experts must learn techniques like adversarial machine learning to harden AI systems. Understanding AI intricacies will become mandatory for effective cyber defense.

Proactive developers should embrace principles like zero-trust networking for AI, perform robust input validation, deploy AI sandboxes, continuously monitor for anomalies, and rigorously test for edge cases. Creative hackers will likely find ways to trick AI that developers cannot yet imagine.

She concluded that rather than AI replacing security jobs, professionals able to leverage AI to enhance cybersecurity will see their value increase. Developers with capabilities to build watertight machine learning systems resistant to manipulation will be perfectly positioned to lead us into the algorithmic future.

Looking deeper, a core theme of the keynote is the need to “protect AI from the world” to ensure security and safety. AI agents ingesting real-time, uncontrolled data need hardened defenses against exploitation.

Some specific recommendations for developers include:

• Isolate AI from the public internet and filter inputs through security stacks like WAFs, DLP systems, and sandbox environments.
• Actively monitor API calls, database queries, and information flows within AI systems for anomalies indicating manipulation.
• Implement robust access controls governing what data AI can touch and what actions can be executed autonomously. Zero trust principles apply.
• Continuously tune machine learning models to detect emerging attacks like adversarial examples and data poisoning aimed at misleading AI.
• Perform extensive ethics testing to catch biases, abuse potential, and unintended outcomes before deploying AI. Model transparency is key.
• Adopt a “DevSecOps” approach with security practices deeply integrated across the machine learning lifecycle.
• Leverage principles like SLSA for software supply chain security to ensure integrity of AI components and dependencies.
• Enforce strict provenance tracking for training data, models, and pipelines to enable auditing and reproduceability.
• Build in model monitoring capabilities to spot drift, degradation, and anomalies indicating problems.

Markstedter drove home that yesterday's security practices are insufficient for the AI-infused future. Developers have a window of opportunity to lay strong security foundations before AI becomes ubiquitous. Those proactive steps taken now will pay exponential dividends later as AI grows more capable and critical for business operations.

In many ways, the journey is just beginning. But the message for developers is clear — integrate security into AI from day one, leverage emerging best practices, and ensure the transparency required to operate AI securely over the long-term. With vigilance and collective responsibility, the promise of AI can be realized safely.

In summary, the emergence of widely-deployed AI requires developers to completely rethink their security posture. Assumptions that worked for protecting human processes do not translate to AI assistants. Failure to account for AI-specific threats early on could have disastrous long-term consequences if flawed systems are entrenched.
