Summary
Detects Cisco AI Defense allowed response events that matched privacy guardrails for personally identifiable information (PII) or payment card data (PCI). It ingests Cisco AI Defense Alerts and uses a Splunk search to identify cases where event_action is "allow" and event_message_type is "response" and where the guardrail ruleset type indicates PII/PCI guardrails. The rule surfaces key fields such as event_id, application_name, guardrail_ruleset_type, guardrail_entity_name, policy_name, and related context (application_id, connection_id, model name) in a tabular view for review. The finding notes that a potentially sensitive dataset was disclosed to an AI application user and should be investigated for data leakage or policy noncompliance. It is designed to be used in conjunction with Cisco AI Defense alerts ingestion via the cisco_ai_defense macro and requiring proper extraction of the required fields. The detection supports security operations by highlighting possible data exposure tied to web applications and is categorized under data protection and critical alerts in the analytics storyline. Administrators should consider expected disclosures (authorized demos or testing) and verify ownership, policy alignment, and the disclosure context to determine if remediation is needed.
