Understanding of AI security risks and frameworks: OWASP LLM Top 10, NIST AI RMF.
Scripting proficiency in Python, PowerShell, or Bash for security automation.
Strong grasp of PCI DSS, NIST CSF, SOC 2, ISO27001, CIS Benchmarks, and MITRE ATT&CK for Cloud.
AZ-500, AWS Certified Security – Specialty, or equivalent cloud security certification.
