How Office 365 Security Protects User’s Data On Cloud– Have A Deeper Look
If we consider business workflow in the last 10 years, it has changed a lot. Every business whether it is a small and large are working on Office 365, which is based on cloud computing. The Cloud platform does not require any introduction as it is the most trending technology used on Personal as well as Professional level. With cloud technology, one can easily get things done remotely at any time because it is available on the cloud server. In fact, it brings the culture of BYOD (Bring-Your-Own-Device) culture in the organizations. So, one can easily do office work from any location.
Cloud Computing itself divided into two different disciplines – Public & Private. The Private cloud defines as when a person rents a space in term of Infrastructure or Platform. It includes Infrastructure as a Service (IaaS) & Platform as a Service (PaaS) Services and a user can manage their data and other components by own.
On the other hand, there is a public cloud that handled by third-party providers over the public internet and known as Software as a Service (SaaS). It includes apps like – Microsoft Office 365, Google G Suite and many other applications.
As we discussed the benefits of Cloud technology, however, there are security risks associated with the public cloud application. Because the service providers are only liable to keep the system up and neglect the security at many ends that can easily penetrate by the hackers. However, Microsoft Office 365 ensures proper security of Office 365 Data data by integrating the multiple security features at a physical and logical level.
But always keep in mind a local backup of your cloud data is always a safe option to protect data from any catastrophic data loss disaster.

Thus, it is good to use the third party Office 365 backup software as Microsoft itself says in their policy.
