01 Executive Overview
Document 03 establishes the authoritative threat modeling framework for Aevum Zenth Conglomerate. Given our multidivisional footprint spanning energy grids, aerospace systems, healthcare networks, financial infrastructure, and autonomous robotics, this model adopts a hybrid STRIDE + PASTA methodology tailored for enterprise-scale OT/IT convergence.
The primary objective is to systematically identify, categorize, and mitigate threats across our $94B operational ecosystem while maintaining strict compliance with ISO 27001, NIST CSF, ITAR, and sector-specific mandates.
02 Asset Classification & Tiering
Assets are categorized by criticality, data sensitivity, and operational impact. Tiering dictates monitoring intensity, encryption standards, and response SLAs.
| Tier | Classification | Examples | Protection Standard |
|---|---|---|---|
| T1 | Crown Jewels | Fusion core blueprints, defense contracts, core banking ledgers, genomic datasets | AES-256-GCM, FIPS 140-3 Level 4, Air-gapped backups |
| T2 | Critical | Smart grid controllers, autonomous fleet AI, patient EHRs, trading algorithms | AES-256, Zero-Trust access, Real-time SIEM correlation |
| T3 | Standard | Employee directories, retail POS systems, public APIs, logistics tracking | AES-128, MFA, Standard patching cadence |
| T4 | Transient | CI/CD pipelines, dev/staging environments, temporary data lakes | Ephemeral credentials, Automated cleanup, Scan gates |
03 Threat Landscape Matrix
Threats are evaluated across probability, impact, and attack vector complexity. Expand categories for detailed vectors and countermeasures.
Likelihood: High | Impact: Critical | Primary Vectors: Supply chain compromise, BEC, zero-day exploits, DDoS
- Advanced Persistent Threats (APTs) targeting aerospace & defense divisions
- Ransomware-as-a-Service (RaaS) campaigns against healthcare & logistics
- Cloud misconfiguration exploitation (S3 buckets, IAM overprivilege)
- Mitigation: EDR/XDR deployment, immutable backups, threat intel feeds (MISP), red team exercises quarterly
Likelihood: Medium | Impact: High | Primary Vectors: Privilege abuse, data exfiltration, accidental exposure
- Malicious insiders leveraging service accounts or VPN tunnels
- Compromised credentials via phishing or credential stuffing
- Mitigation: JIT access, UEBA analytics, DLP policies, mandatory least-privilege reviews
Likelihood: Medium | Impact: Critical | Primary Vectors: IT-to-OT lateral movement, firmware tampering, environmental sabotage
- SCADA/PLC manipulation in energy & manufacturing facilities
- Unauthorized firmware updates in autonomous vehicle fleets
- Mitigation: Network microsegmentation, Purdue model enforcement, hardware root of trust, physical access controls
Likelihood: High | Impact: High | Primary Vectors: Compromised vendors, malicious dependencies, logistics interception
- Software Bill of Materials (SBOM) vulnerabilities in acquired subsidiaries
- Compromised cloud service providers or managed security vendors
- Mitigation: Strict vendor risk assessments, contractual security SLAs, continuous third-party monitoring, secure SDLC gates
