CYB006 — Synthetic Login Activity Dataset (Sample)

XpertSystems.ai Synthetic Data Platform · SKU: CYB006-SAMPLE · Version 1.0.0

This is a free preview of the full CYB006 — Synthetic Login Activity Dataset product. It contains roughly ~1.3% of the full dataset at identical schema, threat-actor-tier distribution, and statistical fingerprint, so you can evaluate fit before licensing the full product.

Dataset Summary

CYB006 simulates enterprise login activity as a 6-phase session state machine across diverse identity infrastructures, with:

• 4 threat-actor capability tiers: script_kiddie, opportunistic, advanced_persistent_threat (APT), nation_state — with per-tier credential attack patterns, MFA bypass propensity, lateral hop distributions, and Golden Ticket / Pass-the-Hash abuse rates
• 8 identity domain types: on-premises AD, Azure AD, Okta, hybrid_joined, SAML federated, zero_trust_ztna, PAW (privileged access workstation), SaaS application portal — each with distinct detection_strength and resilience scores
• MFA challenge methods: disabled, SMS, TOTP, push notification, phishing-resistant FIDO2 — with per-method bypass propensity calibration
• 6 session lifecycle phases: pre_auth_probe, credential_submission, mfa_challenge, session_active, lateral_traversal, session_termination
• Geo-velocity modeling with impossible travel detection via Haversine distance and per-user expected geolocation baselines
• UEBA scoring with calibrated false-positive rates
• Conditional Access (CA) policy enforcement modeling — ZTNA block strength tunable per architecture

Calibrated Benchmark Targets

The full product is calibrated to 12 benchmark validation tests drawn from authoritative identity security sources (Microsoft Digital Defense Report, Okta Customer Identity Trends, Verizon DBIR, CISA Joint Advisories, Mandiant M-Trends, MITRE ATT&CK Evaluations, Gartner IAM Hype Cycle, KuppingerCole Leadership Compass).

Benchmark categories (calibrated in both sample and full product):

1. Credential attack velocity — brute force (~50 RPS), password spray (<1 RPS)
2. Account takeover rate by tier — graduated by attacker capability
3. MFA bypass rate — FIDO2 ≤1%, push/SMS variable
4. Impossible travel rate — 7-12% of sessions
5. Lateral movement depth — capped per tier (script_kiddie ≤1.2 → nation_state ≤14)
6. Privilege escalation rate — conditional on lateral movement
7. MFA fatigue burst timing — Poisson λ=7 burst pattern
8. UEBA false positive rate — calibrated to 10-14% range
9. Golden Ticket / Pass-the-Hash detection gap — stealth modeling
10. Session duration anomaly separation — KL divergence proxy
11. Conditional Access block rate — ZTNA ≥88% for untrusted
12. Kill-chain completion rate — phase-to-phase progression

Sample benchmark results:

Test	Description	Verdict
T01	Credential Attack Velocity	✓ PASS
T02	Account Takeover Rate by Tier	✓ PASS
T03	MFA Bypass Rate (FIDO2)	✓ PASS
T04	Impossible Travel Rate	✓ PASS
T05	Lateral Movement Depth by Tier	✓ PASS
T06	Privilege Escalation Rate	✓ PASS
T07	MFA Fatigue Burst Detection	✓ PASS
T08	UEBA False Positive Rate	✓ PASS
T09	Golden Ticket / PtH Detection Gap	✓ PASS
T10	Session Duration Anomaly Separation	✓ PASS
T11	Conditional Access Block Rate (ZTNA)	✓ PASS
T12	Kill-Chain Completion Rate	✓ PASS

Note: some benchmarks (e.g. nation-state account takeover rates, Golden Ticket detection) require larger sample sizes to converge tightly because they're conditional on small attacker-tier subsets (nation_state ≈ 2% of all sessions, APT ≈ 3%). The full product demonstrates all 12 benchmarks with strong statistical power.
