Microsoft 365 Sharing Poses Security Challenges for Enterprises
Key points
- 61% of security leads report shared access remains active too long.
- Over a third struggle to identify who has access to sensitive files.
- Shared access often outlives its original purpose.
- Access reviews are essential but difficult to implement with current tools.
Cloud Sharing Convenience and Security Risks
Microsoft 365 offers convenience for sharing documents, but this ease of sharing introduces data security challenges. Many organizations lack visibility into who their users are sharing potentially sensitive information with.
Unmanaged Cloud Sharing in Enterprises
Unmanaged cloud sharing is a common problem in enterprise environments. Security teams using Microsoft 365 struggle to identify and manage problematic cloud access. A survey by Wire indicated that 61% of security leads reported shared file access remaining active longer than intended, and over a third had difficulty identifying who had access to sensitive shared files.
Context-Driven Sharing and Persistent Access
Cloud sharing is highly contextual, with employees sharing files for specific purposes. However, shared access often persists beyond its original need; for example, a freelancer might retain access to a project folder after leaving a project. This persistence creates security vulnerabilities.
Challenges with Built-in Governance
Access reviews are crucial for security, as looping file or channel owners into the review process can lead to faster and more accurate audits. The main challenge lies in implementing effective access review processes with the existing built-in governance tools within Microsoft 365.
