d. Logging :
In case of cloud computing, logging is minimal or non-existent. Cloud computing improves log indexing and searches. You can index logs in real-time.
e. Security Software improvement :
The efficiency is improved by security software and all inefficieny process are removed.
f. Secure cloud builds :
When you build cloud, it is important to pre-hardened the security and virtualization advantage is that it hardens the cloud build. It also reduces the time of cloning and patching.
g. Security test :
You can reduce the cost of security testing by hosting on a cloud hosting platform
