Behavioral Baselines & Anomaly Detection

Establish normal patterns for every non-human identity, API key, and service account. When behavior deviates — unusual hours, authentication spikes, new IP ranges, or scope escalation — Netallion AI Assurance alerts before the anomaly becomes a breach.

Static Rules Miss Evolving Threats

Signature-based detection catches known patterns. But when a legitimate service account is compromised and used within its normal permissions — just at unusual times or volumes — only behavioral analysis catches it.

How Behavioral Baselines Work

Learning, baselining, and continuous monitoring in a fully automated pipeline.

# Baseline pipeline
1.COLLECT — Ingest authentication logs, API call records, and access events
2.PROFILE — Build per-identity profiles: time windows, call volumes, IP ranges, resources
3.BASELINE — Compute statistical baselines with 14-day rolling window
4.SCORE — Every new event scored against baseline (z-score, percentile rank)
5.DETECT — Flag events exceeding threshold (configurable: 2-sigma, 3-sigma, 4-sigma)
6.ALERT — Notify with full context: what deviated, by how much, historical norm

6 Anomaly Detection Types

Unusual Access Hours

High

A service principal that normally operates 9-5 UTC starts making API calls at 3 AM. The baseline flags this as a 4-sigma deviation from normal operating window.

Authentication Spike

Critical

Failed authentication attempts for a managed identity jump from a baseline of 2/day to 200/hour. Indicates credential stuffing or a misconfigured rotation.

New IP Range

High

An API key that has only been used from 10.0.0.0/8 suddenly appears from a public cloud IP in a different region. Geographic or network drift detected.

Scope Escalation

Critical

A token that historically accessed 3 repositories now requests access to 47. The baseline detects resource scope expansion beyond the established norm.

Volume Anomaly

High

API call volume for a service account jumps 10x above baseline in a 15-minute window. Could indicate data exfiltration or a runaway automation.

New Resource Access

Medium

A non-human identity accesses a database or storage account it has never touched before. First-access events are flagged against the approved resource list.

Built for NHI Security

Per-Identity Profiles

Every service principal, managed identity, and API key gets its own behavioral profile. No one-size-fits-all thresholds.

Adaptive Baselines

Baselines evolve with legitimate changes. Approved scope expansions and new deployments are absorbed into the baseline after review.

Time-Window Analysis

Detect anomalies at multiple time scales: per-minute spikes, hourly trends, daily patterns, and weekly cycles.

Alert Correlation

Multiple anomalies on the same identity are correlated into a single incident. Unusual hours + new IP + scope expansion = high-confidence compromise.
