E. A and D

A and D A. Choose a hypervisor with a smaller footprint for a reduced attack surface. D. Monitor for signs of compromise by analyzing hypervisor logs on an ongoing basis. For securing the hypervisor in an Infrastructure as a Service (IaaS) environment, Infrastructure4Sure should choose a hypervisor with a smaller footprint, which reduces the attack surface by minimizing unnecessary components and functionalities that could be exploited. Additionally, Infrastructure4Sure should monitor for signs of compromise by regularly analyzing hypervisor logs. Monitoring logs helps detect any suspicious or unauthorized activities that might indicate a security breach or compromise.
