AI for Threat Hunting

As artificial intelligence reshapes cybersecurity, 67% of organizations now use AI to strengthen their defense strategies. Yet, most SOC teams still struggle to keep up with the avalanche of alerts and complex attack chains that evolve faster than legacy systems can respond.

This guide examines AI for Threat Hunting, explaining how machine learning transforms real-time detection and response in modern SOC environments.

DataSunrise’s advanced AI/ML Security platform delivers Zero-Touch Security Orchestration with Autonomous Threat Detection, Context-Aware Protection, and Surgical Precision across 50+ supported platforms.

Understanding AI-Driven Threat Hunting

AI-driven threat hunting leverages machine learning models to identify anomalies and suspicious behavior that traditional SIEM rules might miss. Unlike static signature-based systems, AI models continuously learn from live database activity monitoring data, adapting to new tactics and minimizing false positives.

Traditional tools rely on human-defined thresholds, while DataSunrise’s machine learning tools autonomously correlate patterns across audit trails, role-based access controls, and database firewalls. This delivers real-time context, ensuring threats are detected with maximum accuracy and minimal noise.

Critical AI Threat Vectors in SOC Environments

AI brings precision—but it also introduces new attack surfaces. SOC teams must watch for these critical vectors:

1. Model Poisoning: Attackers manipulate training data to corrupt AI decision-making. DataSunrise mitigates this through continuous data protection and audit logs.
2. Adversarial Evasion: Subtle input alterations deceive classifiers. By combining filtering with behavior analytics, DataSunrise exposes these anomalies before damage occurs.
3. Data Exfiltration via APIs: Unauthorized access paths leak sensitive data. DataSunrise enforces access controls and dynamic data masking to restrict exposure.
4. Privilege Escalation Attacks: Compromised accounts gain unauthorized admin rights. With least privilege enforcement and real-time notifications, DataSunrise keeps escalation attempts under control.

Each layer integrates seamlessly with DataSunrise’s security policy framework, delivering “Maximum Security, Minimum Risk.”

Implementing AI for Threat Hunting

Effective AI threat hunting requires models that understand behavioral baselines and can flag deviations autonomously. DataSunrise’s ML-powered analyzers exemplify this with adaptive risk scoring.

Example: AI Threat Detection Engine

class AIThreatEngine:
    """
    Template-aligned detector that mirrors DS-style signal fusion.
    Inputs are stitched from Audit Trail, Activity Monitoring/History,
    RBAC, Firewall, and Data Discovery contexts.
    """

    def __init__(self, z_thr: float = 2.5):
        # simple per-entity baseline knobs (stand-in for UBA profiles)
        self.z_thr = z_thr

    def analyze(self, ev: dict) -> dict:
        """
        ev example:
        {
          "user":"svc_app", "role":"report_reader",
          "action":"SELECT", "object":"customer.ssn",
          "is_sensitive": True,           # from Data Discovery tags
          "rule_matches": ["high_risk_read"],  # Audit Rules hits
          "firewall_blocked": False,      # Database Firewall event
          "qps_z": 3.1,                   # deviation vs per-user baseline
          "err_z": 0.4,                   # errors vs baseline
          "peer_dev": 2.2                 # peer-group deviation
        }
        """
        # Core anomaly score (z-scores + peer deviation)
        score = max(ev.get("qps_z", 0), ev.get("err_z", 0), ev.get("peer_dev", 0))

        # Contextual boosters (policy correlation)
        if ev.get("is_sensitive"):
            score += 0.7
        if ev.get("rule_matches"):
            score += 0.8
        if ev.get("firewall_blocked"):
            score += 1.0
        if ev.get("role") == "report_reader" and ev.get("action") not in ("SELECT",):
            score += 0.5  # least-privilege nudge

        sev = "LOW"
        if score >= self.z_thr + 1.0:
            sev = "HIGH"
        elif score >= self.z_thr:
            sev = "MEDIUM"

        return {
            "threat_detected": sev != "LOW",
            "risk_score": round(score, 2),
            "severity": sev,
            "explanations": {
                "baseline_signals": ["qps_z", "err_z", "peer_dev"],
                "policy_context": ["is_sensitive", "rule_matches", "firewall_blocked"]
            },
            "recommendations": [
                "Open audit trail and correlate with matched audit rules.",
                "Enable/verify dynamic masking on sensitive objects.",
                "Review RBAC/least-privilege and tighten if needed.",
                "Subscribe Slack/SIEM notifications for HIGH events; generate report."
            ],
        }

This example illustrates how DataSunrise’s AI Threat Engine fuses anomaly metrics with contextual security data. It combines user behavior baselines, peer-group deviations, and policy signals from audit trails, activity history, role-based access controls, and database firewall events. By weighting each signal, the engine produces adaptive risk scores and prioritizes alerts for sensitive or policy-violating actions—turning AI detection into a unified, actionable defense workflow within DataSunrise.
