Exam CCAK topic 1 question 203 discussion

D. Isolation failure A hypervisor bug that results in the access of RAM of a neighboring cloud computer belonging to another cloud customer is an example of an isolation failure. In cloud computing, isolation is a critical security measure that ensures that the resources and data of one customer are kept separate from those of another. The hypervisor plays a key role in maintaining this isolation by managing virtual machines on shared physical hardware. When a hypervisor bug allows one virtual machine to access the memory of another, it represents a failure of this isolation mechanism. This can lead to unauthorized access to sensitive data and compromise the security and privacy of cloud customers. Isolation failures highlight the importance of robust hypervisor security and effective vulnerability management in cloud environments.

P# 55 Isolation failure—Cloud computing often uses shared resources and multitenancy. There are security mechanisms to separate storage, memory, routing, etc., between different tenants. Failure of isolation mechanisms is considered a risk.
