Taylor Lehmann, Director at the Office of the CISO, and Luis Urena, Cloud Security Architect at Google Cloud, tackle the complexities of securing inherited cloud environments. They discuss the risks of late security team involvement and the impracticality of drastic measures like 'nuking' the environment. Instead, they offer strategic steps for immediate security improvements, such as managing overly permissive roles. They also evaluate the necessity of compromise assessments and the balance between current priorities and securing new systems.
