In this episode of the Security Swarm Podcast, the host Andy Syrewicze and the guest Philip Galea discuss the security implications of Microsoft's AI assistant Copilot, which is integrated into the Microsoft 365 suite. They explore how Copilot's ability to surface information from an organization's Microsoft 365 data can create significant security risks, especially for companies that lack the operational maturity to properly manage permissions and access controls.
The discussion also covers Microsoft's reactive approach to security in some of its products, where default settings are often not secure enough, and the company is slow to address these issues. The host and the guest emphasize the need for organizations to take a proactive approach to security, continuously reviewing and updating their security posture to mitigate the risks posed by Copilot and other Microsoft 365 features.
The episode also introduces Hornetsecurity's Tenant Manager tool, which aims to help organizations better manage and enforce their Microsoft 365 security settings, providing a centralized and automated way to ensure that their environments are configured according to best practices.
