Google Cloud Platform CIS security controls

This security configuration benchmark covers foundational elements of Google Cloud Platform. The security controls detailed here are important security considerations when designing your infrastructure on Google Cloud Platform. Most of the security controls provided with this release of the benchmark (1.0.0) covers security considerations only at individual Project level and not at the organization level.

4.6 Ensure VM disks for critical VMs are encrypted with Customer-Supplied Encryption Keys (CSEK)  
5 Storage
5.1 Ensure that Cloud Storage bucket is not anonymously or publicly accessible 
5.2 Ensure that there are no publicly accessible objects in storage buckets  
5.3 Ensure that logging is enabled for Cloud storage buckets  
6 Cloud SQL Database Services 
6.1 Ensure that Cloud SQL database instance requires all incoming connections to use SSL 
6.2 Ensure that Cloud SQL database Instances are not open to the world  
6.3 Ensure that MySql database instance does not allow anyone to connect with administrative privileges. 
6.4 Ensure that MySQL Database Instance does not allows root login from any Host 
7 Kubernetes Engine
