AI benefits/risks Why we need a ‘zero-trust for code’ behavioral approach to secure software May 11, 2026 Share By Ken Ammon (Adobe Stock) COMMENTARY: Enterprise security has long relied on a single classification model for code: Is this artifact malicious? That question no longer suffices. For years, the underlying approach to malware analysis has remained the same. Security systems observe runtime activity, correlate it to known techniques or patterns, and produce a probabilistic judgment. If there’s high confidence, the artifact gets blocked. If not, it’s labeled suspicious and escalated to an analyst for review. [ SC Media Perspectives columns are written by a trusted community of SC Media cybersecurity subject matter experts.

This reframes security from post-execution detection to pre-execution authorization. This model aligns with a zero-trust for code approach that applies zero-trust principles directly to software artifacts by requiring that behavior get evaluated and authorized before execution. Moving beyond indicators Traditional detection models depend on prior knowledge. Signatures, reputation feeds, malware family clustering, anomaly scoring, and many “behavioral” systems rely on pattern matching against previously observed threats. This worked when reuse was common and mutation was slow. In an environment shaped by automation and AI-assisted coding , modern artifacts are often never-before-seen events. Their hashes, strings, packers, and control flow may never repeat. Even runtime behavior can be staged, delayed, or environment-aware, evading short detonation windows. When defense depends on recognition and attackers can generate variation on-demand, classification becomes unstable. Behavioral intent analysis does not ask whether an artifact resembles something malicious. It evaluates what execution paths are possible, what system interactions are encoded, what privileges are required, what persistence mechanisms are embedded, and what external communications are initiated. Assess intent before execution Despite the fact that AI enables endless mutation, malware cannot achieve its objective without performing certain categories of action: escalating privilege, modifying system state, injecting into processes, establishing covert communications, accessing sensitive data, or altering configuration. To counter AI-weaponized threats, behavioral intent performs deeper analysis than surface scanning or heuristic scoring. At a practical level, it involves examining: Control flow and execution paths. System interactions across file, registry, process, memory, and network layers. Privilege requirements. Persistence and propagation mechanisms. Potential blast radius and operational impact. This analysis can combine static control-flow modeling and dynamic observation, but timing remains the main distinction. The decision occurs before trust gets granted. Rather than detonating an artifact and observing outcomes, intent analysis evaluates what can happen and measures it against policy. The operational question shifts from “How quickly can we respond after execution?” to “Should we allow this artifact to execute at all?” In the process, security teams can move from reactive detection to preemptive authorization. In this sense, zero-trust for code reframes software execution as a policy enforcement point, where trust gets established only after behavioral evaluation, not assumed based on origin or prior validation. Behavioral detection vs. behavioral intent There’s an important distinction between behavioral detection and behavioral intent analysis. Behavioral detection typically starts with runtime telemetry and maps observed activity to known technique libraries such as MITRE ATT&CK to drive correlation and alerting. It’s output runs as probabilistic, malicious, suspicious, or unknown, often accompanied by a confidence score. When there’s low confidence, human triage becomes the decision engine. Behavioral intent analysis, meanwhile, produces a structured model of what an artifact was designed to do, independent of prior exposure. It categorizes encoded actions and evaluates them against explicit policy. Instead of a “likely malicious” verdict, intent analysis delivers a determination as to whether specific behaviors violate, or comply with, defined operational, security, or regulatory constraints. This becomes critical in CI/CD and software supply chain contexts. Build artifacts, scripts, automation jobs, and third-party components often inherit trust by origin or signature and are rarely evaluated as malware candidates before promotion. As software supply chains extend beyond organizational boundaries, weak artifact validation introduces opportunities for pipeline poisoning and downstream compromise. Behavioral intent analysis enables enforceable promotion gates that are based on encoded behavior, not provenance alone. Here's where we can operationalize zero-trust for code with deterministic, behavior-based controls at the build, promotion, and deployment stages across the software lifecycle. Probabilistic models, including many machine learning classifiers and LLM-based systems, generate likelihoods and confidence scores. They are valuable for pattern discovery and triage acceleration, but their outputs are inherently non-deterministic. Given the same input, they may produce slightly different results. It’s an acceptable variability for investigation support, but problematic for policy enforcement and audit. Decisions need to be traceable to observable behavior and explicit policy logic, not model confidence alone. Behavioral intent analysis was designed to deliver a deterministic, structured, explainable record: categorized behaviors mapped to impact, tied to policy, and linked to artifact provenance. Under the same policy conditions, the same artifact generates the same outcome. For organizations operating under regulatory scrutiny, that consistency matters. Enforcement decisions must withstand audit, incident review, and compliance validation. In other words, we have to make them repeatable and defensible. As AI accelerates artifact generation and compresses attack timelines, pre-execution controls shift the balance of power back toward defenders. Behavioral intent analysis lets organizations operationalize this transition. Instead of reacting to execution events, security teams can enforce trust decisions before internal or external software can run in the first place. It’s the foundation of a zero-trust for code model, where execution itself becomes the final checkpoint for policy enforcement.
