The advent of cloud collaboration suites has revolutionized the way we work, but it also poses significant security risks if not managed properly. Oversharing unmanaged access is a growing threat that can lead to sensitive information falling into the wrong hands. By adopting a proactive approach and implementing governance tools that provide complete visibility at every level, organizations can regain control of their cloud collaboration suites and protect themselves against this danger.

The advent of cloud collaboration suites has revolutionized the way we work, making it easier to connect people, ideas, and information across geographical boundaries. Platforms like Microsoft 365 have enabled seamless sharing of documents, files, and even entire projects with colleagues, freelancers, or business partners. While this level of accessibility was once considered a luxury, it is now a necessity in today's fast-paced, globally interconnected work environment.
However, the convenience of cloud collaboration comes with a hidden cost: the increased risk of oversharing unmanaged access. This phenomenon occurs when users share content with others, but either invite more people than they needed to or forget to remove them later on. The result is a situation where sensitive information falls into the wrong hands, posing significant security risks to the organization.
The problem of oversharing in cloud collaboration suites is multifaceted. It can manifest in various ways, including:
* Users sharing access to project folders without revoking it when the project is complete.
* Sharing documents through Teams channels and failing to consider the impact on new team members who may not be aware of the shared content.
* Storing sensitive information in shared folders with multiple users, forgetting that they have access to the same files.
These scenarios are not unique and can happen to anyone. However, they demonstrate the dangers of oversharing unmanaged access and highlight the need for organizations to implement robust security measures to mitigate these risks.
In addition to the risks associated with oversharing, cloud collaboration suites also pose a threat to an organization's security when it comes to external sharing. When users share content with external partners or contractors, they are relying on the security practices of that partner or contractor to keep them safe. If this external partner or contractor is breached, attackers could gain access to sensitive information shared by the user.
The principle of least privilege has become a best practice in recent years to prevent such breaches. This principle emphasizes the need to limit access to sensitive information to only those who require it to perform their jobs. However, in many cases, users may not have the necessary training or expertise to implement this principle effectively.
To regain control of cloud collaboration suites and mitigate the risks associated with oversharing unmanaged access, organizations must adopt a proactive approach. This involves implementing governance tools that provide visibility into shared content and allow security teams to monitor and remediate unwanted access.
The current state of governance tools in cloud collaboration suites is insufficient for this task. Most governance tools focus on managing users and groups rather than providing detailed insight into access rights on unstructured data like files shared through Teams, OneDrive, or SharePoint. This lack of visibility makes it difficult for security teams to identify and address the risks associated with oversharing.
Fortunately, there are solutions available that can provide complete visibility at every level. Tenfold is a cloud governance suite that offers in-depth analysis of access rights on unstructured data. Its centralized hub provides a full breakdown of shared content across Teams, OneDrive, and SharePoint, allowing security teams to identify and address the risks associated with oversharing.
Furthermore, tenfold's Access reviews feature enables security teams to prompt file owners to review access to the content they have shared, ensuring that outdated access is removed. This feature can be scheduled at set intervals or tied to specific events, such as a person switching to a different team or leaving the organization.
In conclusion, cloud collaboration suites have revolutionized the way we work, but they also pose significant security risks if not managed properly. Oversharing unmanaged access is a growing threat that can lead to sensitive information falling into the wrong hands. To mitigate these risks, organizations must adopt a proactive approach and implement governance tools that provide complete visibility at every level.
By doing so, organizations can regain control of their cloud collaboration suites and protect themselves against the dangers of oversharing unmanaged access. Tenfold's cloud governance suite offers the necessary features to achieve this goal, providing security teams with the insight they need to monitor and remediate unwanted access in real-time.
