This goes out to my boss because he wanted to know about this new thing

Get your team on board. Your employees are likely going to be your biggest security risk. Training, seminars, and lessons may all be necessary to ensure that they are current on modern security standards. 

 Invest in identity management and authentication services. Cloud services are highly accessible and this can be a double-edged sword. In order to secure your cloud-service, you need to control your credentials. 

Always have a very clear chain of command. Employees should always be aware of their own responsibilities during a security event and the chain of command that flows above them.

Invest in a layered security platform. A layered security platform will divide your organization's infrastructure based on priority, thereby ensuring that the most important items are behind multiple layers of security -- without compromising the performance of other components of the system. 

Restrict permissions to those absolutely necessary. Every employee should have only the permissions that are necessary for them to successfully complete their work.

 Encrypt files and backup files.  Any copy of a company's files needs to be treated with the exact same level of security as the originals. Your cloud computing solution should encrypt all of its files and its backup files. Even if there is a security breach, the company will be able to recover.
