Transition from a reactive to a proactive security posture by auditing the critical safety protocols within your Google Admin Console. This session moves beyond basic settings to address modern infrastructure risks, including the "active" security threat of legacy overshared data being surfaced by generative AI tools like Gemini. We will conduct a technical walkthrough of API controls to manage third-party app access, discuss the implementation of "walled gardens" for student Gmail security, and explore the deployment of Data Loss Prevention (DLP) rules to protect sensitive school information. You will also learn how to leverage the Alert Center and Investigation Tool to triage incidents and remediate inappropriate sharing at scale across your entire domain.
