# Adnan Koroth

> Staff Security Engineer who builds internal security platforms across cloud,
> identity, detection, and AI-enabled operations on AWS and GCP. Builds where
> commercial tools are costly, fragmented, or miss company-specific risk —
> end to end: problem, architecture, implementation, and operational feedback.

## Systems (built or co-architected)

- Cerberos: a four-scanner cloud-posture suite — one scanner per attack
  surface (container images via Trivy; AWS config and perimeter via Steampipe;
  Kubernetes control plane via Kubescape; node operating system per-image).
  Ephemeral compute, one shared finding contract.

- IAMGuru: multi-cloud IAM analysis built end to end. Models IAM as
  reachability — privilege-escalation paths, per-principal blast radius, and
  AWS-to-GCP Workload Identity Federation trust bindings — mapped to MITRE
  ATT&CK, with data-driven risk scoring. Runs for about $8/month.

- Pentagon (co-architected): a unified findings warehouse. One four-axis
  taxonomy across 6+ heterogeneous scanners, fingerprint deduplication, a
  finding lifecycle with SLA, and bounded AI agents (deterministic
  classification, scoped I/O, no destructive actions, human review).

- Watchman: an AI-enriched SOC pipeline. Raw EDR detections and WAF spikes
  are re-queried for full context, assessed by Claude under a strict output
  schema (severity, actor, confidence, recommendation), attributed to the
  affected person, and delivered to the analyst channel with a
  human-in-the-thread clarification loop. Cases auto-close only above a
  confidence threshold with nothing outstanding; the system assesses and
  asks but never acts autonomously. Model inputs and outputs are persisted
  for review. https://adnan.koroth.xyz/systems/watchman

- JIT Access: a Slack-native just-in-time AWS access portal. Engineers
  request elevation via a Slack slash command; the request is routed to the
  account owner's channel as a Block Kit message with Approve/Deny actions;
  on approval, the elevated role is granted via IAM Identity Center /
  STS role assumption for a bounded session and auto-revoked at expiry by a
  DynamoDB TTL plus a sweeper that enforces revocation at the IAM boundary.
  Runs on ECS + DynamoDB; the Slack integration uses Socket Mode so no
  public HTTP endpoint is exposed. Replaces vendor PAM with an in-house
  bounded-trust workflow aligned to ISO 27001 A.9 / CIS least-privilege.

## Notable prior work

- Cars24: built cloud security posture from scratch across AWS and GCP for
  four countries and 6,000+ employees; led an XDR rollout (Palo Alto Cortex)
  to 6,000+ endpoints in under 90 days; deployed Prisma Access as the SASE
  solution; designed backup, redundancy, and information-security continuity
  controls to support ISO 27001 certification.
- Castellum Labs: cloud security architecture and roadmaps for enterprise
  clients on AWS and on-prem; built a SIEM platform, a virtual SOC training
  environment, an internal CA, and ran phishing-simulation programs for MNC
  clients.

## Position on AI in security

AI is used as a force multiplier for triage and enrichment, kept deliberately
bounded: deterministic classification, confidence thresholds, scoped read/write
surfaces, no autonomous destructive actions, logged inputs and outputs, and a
human on disputed decisions. The restraint is the engineering, not a limitation.
