Automating Security with AI: The BAS Revolution

Security teams often simulate attacks to test their defenses, but there's a glaring inefficiency in the current system: the manual crafting of detection rules. These Breach-and-Attack-Simulation (BAS) tools surface critical findings, yet translating them into actionable intelligence has remained a manual, labor-intensive task. But what if AI could fill this gap?

Bridging the Gap with Automation

Enter a breakthrough: partially automating the translation of BAS findings into Sigma rules. These rules serve as vendor-neutral detection formats essential for security information and event management (SIEM) systems. The key innovation? A deterministic synthesis function that maps each finding to a Sigma rule using a modest template library of 23 categories, aligned with the OWASP LLM and Web Top 10. This isn't a partnership announcement. It's a convergence.

On two distinct corpora, namely a 17-probe LLM and a 23-probe Web, every bypassed-probe finding is converted into a starter rule. Impressively, all 17 emitted rules were successfully parsed and integrated into backends like Splunk and Elasticsearch. Imagine deploying these rules into a live OpenSearch SIEM environment: the LLM rules effectively fired on 30% of a held-out AdvBench subset and 14% of HarmBench, with a 7.7% false-positive rate on benign data.

The Future of Security Automation

Why should this automation matter to security teams? First, it offers a verifiable, byte-stable path from BAS findings to deployable Sigma rules, enhancing reproducibility and precision. The approach trades the expansive reach of generative AI methods for exact reproducibility and a typed traceback from any alert back to its source probe. In an industry where precision can mean the difference between staving off an attack or succumbing to it, this shift could be revolutionary.

But here's the kicker: if agents have wallets, who holds the keys to their security insights? It's a question that underscores the broader implications of agentic systems in cybersecurity. As AI continues to integrate with security practices, we're building the financial plumbing for machines in a landscape where every byte counts.

Ultimately, this is about more than just speeding up the response to threats. It's about redefining the boundaries of machine autonomy in cybersecurity. The compute layer needs a payment rail, not just for transactions but for the easy flow of security intelligence as well. The collision of AI and cybersecurity isn't just inevitable. it's already reshaping the industry. The AI-AI Venn diagram is indeed getting thicker, and those who adapt will find themselves at the forefront of a new era in digital security.
