PROFILE
Christina Aravantinou
Christina Aravantinou developed two monitoring rules for AWS Bedrock model invocations in the panther-analysis repository, focusing on enhancing security and governance. She implemented detection for abnormal token usage by establishing threshold-based alerting, as well as guardrail intervention monitoring to expose misuse and policy violations. Using Python and YAML, Christina applied rule-based monitoring techniques to improve observability and incident response readiness for Bedrock usage. Her work addressed the need for faster detection of policy breaches and stronger governance of AI/ML model activity in cloud environments. The depth of her contribution lies in integrating security monitoring with automated policy enforcement workflows.
