  • Implement and oversee a risk-based security assessment program for critical assets.
  • Maintain and update standards-based control documentation, including evidence of control effectiveness.
  • Stay informed on emerging technical security threats and communicate relevant risks to management.
  • Utilize an agile approach to integrating information security principles across the organization.
  • Work in conjunction with other departments to ensure consistent application and adoption of information security best practices.
  • Provide assistance in responding to security-related queries from clients, vendors, and other third parties as requested by management.
