Arasy Dafa Sulistya Kurniawan

SOC Engineer at Zentara. Blue team practitioner specializing in detection engineering, threat intelligence, deception technology, cloud security, and security architecture. I turn threat intel into high-fidelity detections, build deception environments to study adversary behavior, and design resilient security architectures across cloud and hybrid environments.

Focus Areas

Detection Engineering

  • Sigma, YARA, and KQL rule development for multi-platform coverage (SIEM, EDR, Cloud)
  • MITRE ATT&CK mapping & coverage analysis to prioritize detection gaps
  • High-fidelity correlation rules tuned for low false positives
  • Detection-as-code pipelines with CI/CD integration

Threat Intelligence

  • TI platform integrations (MISP, OpenCTI) for automated enrichment
  • Threat actor profiling & campaign tracking
  • IOC management & sharing via STIX/TAXII
  • Intel-driven detection rule creation and hunting hypotheses

Deception Technology

  • Honeypot/honeynet deployment & management (Cowrie, Dionaea, T-Pot, custom)
  • Deception architecture for lateral movement detection
  • Adversary engagement & behavioral analysis in controlled environments
  • Canary tokens & breadcrumb placement for early warning

Cloud Security

  • Cloud-native detection for AWS/Azure/GCP (CloudTrail, GuardDuty, Security Hub, Defender for Cloud)
  • Container & Kubernetes runtime security (Falco, Tracee, custom eBPF)
  • IaC security scanning & policy-as-code (OPA/Rego, Checkov, tfsec)
  • CSPM/CIEM posture management and drift detection

Security Architecture

  • Zero Trust & defense-in-depth design for hybrid environments
  • Security control mapping (NIST 800-53, ISO 27001, CIS Benchmarks)
  • Data flow threat modeling (STRIDE, PASTA)
  • Secure reference architectures for cloud migration
