In terms of encryption at rest, Microsoft utilizes BitLocker to secure its servers and implements per-file encryption where each file update is encrypted using a distinct key.

These keys are stored in a separate location, making it difficult for hackers to decode encrypted OneDrive files even if they manage to breach Microsoft servers.

Access And Sharing Controls

The OneDrive Application offers various options for restricting access to your files and folders. Typically, when you click the Share button on any Microsoft 365 productivity app, you receive a shareable link that can be given to anyone. However, within the OneDrive Admin Center, you can control who can access files through these links. Shared link access is divided into three categories:

  • Anyone with the link can access the file
  • Links are accessible only by users within the organization
  • Only specific individuals permitted by the end user can access the link

Furthermore, you can set permissions for how users interact with shared libraries or folders. You can either make files read-only by default or enable editing permissions. If you choose the latter, users can move, rename, share, delete, and copy content on files and folders. Additionally, you can set an expiration date or password-protect shareable links to further shield sensitive data from public view.

OneDrive Security Concerns: Cloud Storage Risks

Businesses that prioritize having more control and visibility over corporate data face various issues when using consumer-grade file sync services (sometimes referred to as CGFS services), such as OneDrive. The most well-known illustration is Dropbox Personal, although this also holds true for the standard and unrestricted versions of OneDrive app and Google Drive.

Data Theft: Many problems with CGFS services stem from insufficient oversight. IT administrators and business owners often lack awareness of product installations and are unable to control different devices syncing with corporate shares. As information gets replicated on numerous personal devices, administrators lose control over the data, and the risk of data theft or misuse increases significantly.

Data Loss: sync solutions are designed to automatically update files and folders across all connected devices. Consequently, any file deletions or incorrect changes will be synced across all devices. Without history retention or deleted-file protection, previous versions may be lost in the cloud. Additionally, an end-user could intentionally delete files permanently.

Corrupted Data: A CERN study revealed that silent data corruption occurs in approximately 1 out of every 1500 files. Many users and organizations rely on solutions to maintain the latest and most accurate file versions without realizing that few solutions offer protection against data corruption. Even if backups are available, most CGFS services don’t provide an easily accessible method to request backed-up data copies.

Sharing Sensitive Information: Personal sharing solutions don’t offer centralized oversight of shared information and its recipients. Once information is shared, it’s generally impossible to limit the access period or the number of downloads. This lack of control can result in the loss or unauthorized sharing of critical business documents, increasing the risks of violating privacy agreements and causing disputes.

Compliance Violations: Due to minimal file retention and access controls in CGFS solutions, compliance violations are a significant concern. Compliance policies often mandate that files should be retained for specific durations and accessed only by certain individuals, necessitating strict access controls and oversight.

Loss Of Accountability: The absence of reports, alerts, and logs for user activities can lead to a direct loss of accountability. Changes to individual documents, user accounts, organizations, passwords, and policies cannot be tracked effectively, resulting in the risk of unmonitored and unauthorized changes to files and configurations.

Loss of File Versions: Since CGFS solutions don’t maintain all file versions or keep a history of changes, including the corresponding people, devices, and dates, modifications to files can result in a direct loss of information. Incorrect changes or local data corruption can cause permanent loss of file versions, making it impossible to trace the cause and source of the loss.

Business applications address many of these known issues without sacrificing the features that make consumer file sync services user-friendly and convenient. As a result, numerous companies have implemented formal policies against or discouraged employees from using personal applications, accounts, or devices.

Wrapping Up

OneDrive for Business offers a fantastic platform for companies aiming to safeguard and share their data securely.

With extensive safety features like multi-factor authentication, access management, data leakage protection, ransomware detection and recovery, coupled with Microsoft Defender integration, it offers a strong shield against security risks.

Nonetheless, it’s crucial for businesses to adhere to recommended practices to guarantee the highest level of security is enforced.
