SharePoint is an incredibly useful tool for businesses, as it allows employees in all departments to work together effectively. However, using SharePoint to share sensitive data and other content can present serious security risks for your organization. Follow these SharePoint security tips to create a secure SharePoint environment and an overall effective security strategy.
1. Control Access to Sensitive Data
In the average SharePoint Online environment, 17.4 percent of documents contain sensitive data, such as customer payment details or personally identifiable information. It is very unlikely that every person in your organization needs to have access to all of this sensitive data, so it’s a good idea to restrict access to these documents to only those users who really need it. The fewer the people who have access to sensitive data, the lower the risk of a data leak.
2. Control External Data Sharing
If you use SharePoint to share information with collaborators from other companies, make sure you’re not sharing any sensitive data. The well-known Target data breach that occurred in November 2013 was caused by hackers stealing sensitive information from a third-party vendor. When you share sensitive data with external partners, remember that you can’t guarantee that their environment is secure. In SharePoint Online, you can use the External Sharing feature to invite external users to view content. It’s a good idea to disable this feature by default and only turn it on when it’s absolutely necessary. (source)
