  • Establish a taxonomy of indicators of compromise (IOCs) and share this detail with other security colleagues, including the security operations center (SOC), information security engineers and analysts, as well as other counterparts within IT
  • Validate IT infrastructure and other reference architectures for security best practices and recommend changes to enhance security and reduce risks, where applicable
  • Validate security configurations and access to security infrastructure tools, including firewalls, IPSs, WAFs and anti-malware/endpoint protection systems
  • Review network segmentation to ensure least privilege for network access
  • Liaise with the Information Security Compliance and Internal Audit teams to review and evaluate the design and operational effectiveness of security-related controls
  • Review security technologies, tools and services, and make recommendations to the broader security team for their use, based on security, financial and operational metrics
