  • Build custom solutions in support of active cyber threat and cyber defense operations.
  • Track system and organizational security posture over time and brief trends to the ISSM/ISSO.
  • Automate threat assessment and reporting work, and support audits.
  • Fix vulnerabilities, reduce risk and recommend system security changes when needed.
  • Watch for and investigate security incidents, and train staff and customers on security procedures.
