OneDrive security best practices include learning all security concerns related to business purposes. Let’s learn some tips for business as well as personal OneDrive security best practices.

Enterprises are fast adapting to cloud technology and choose Office 365 cloud platform to conduct their businesses. They get started with MS Office Exchange Online and get an OneDrive environment for free. For businesses that have already made the switch to OneDrive, there might be challenges of data security, governance, and compliance. Even though OneDrive provides robust security features, there might be some user-based activities that put the confidential data at unknown risk. This is because the users upload some secretive documents on the cloud either intentionally or unintentionally and share it with everyone.

OneDrive Security Best Practices for Business

What is OneDrive? It is a cloud platform where the office-related Word, Excel, etc., files are stored and saved. Around the world, a number of enterprises store and process all their data through OneDrive. Like schools, colleges, hospitals, and healthcare providers store their HIPAA-HITECH information on OneDrive. When the data is regulated by international security standards, then there is a requirement for data storage purposes and cloud & physical data protection. When the workstation rights are shared amongst many users, this type of scenario breaks the OneDrive for Business security completely. For the billing purpose, Microsoft gives Level 1 compliance with PCI DSS. But for security concerns, Microsoft clearly states that MS Office 365 services are not to be used for storing and transmitting cardholder information. This implies that OneDrive is not to be used by enterprises for storing, transmitting, or processing cardholder data. This is the best tip for OneDrive security best practices. Whether it is OneDrive or OneDrive for Business, the security factors remain unique with only one aim; that is OneDrive cloud data security.
