SharePoint and Data Loss Prevention
At our organization, we recognize the importance of protecting sensitive information within SharePoint. To achieve this, we have implemented data loss prevention (DLP) policies that allow us to identify, monitor, and automatically protect sensitive items across our site collections.
SharePoint DLP Policies
SharePoint DLP policies are a set of rules that are defined and applied to identify and protect sensitive information within SharePoint. These policies can be created and managed from the SharePoint admin center or using PowerShell.
To create an effective SharePoint DLP policy, we need to understand the different components that make up the policy. These components include policy rules, policy tips, actions, and exceptions. By configuring these components, we can define the conditions under which sensitive information is identified and protected.
Sensitive Information in SharePoint
Sensitive information within SharePoint can include anything from financial data to personal identifiable information (PII). To protect this information, we need to identify it and apply appropriate protection measures.
One way to identify sensitive information within SharePoint is by using DLP queries. These queries can be used to scan SharePoint site collections for sensitive information based on predefined conditions. Once detected, we can then apply protection measures such as blocking access or encrypting the data.
Another way to protect sensitive information within SharePoint is by using sensitivity labels. Sensitivity labels can be applied to documents and other content within SharePoint to classify them according to their level of sensitivity. This classification can then be used to apply protection measures such as encryption or access restrictions.
In conclusion, SharePoint DLP policies are an essential tool for protecting sensitive information within SharePoint. By understanding the different components of these policies and using tools such as DLP queries and sensitivity labels, we can effectively identify and protect sensitive information within our organization.
Working with DLP Policies
When it comes to data loss prevention in SharePoint, DLP policies are a crucial aspect to consider. These policies help us identify, monitor, and protect sensitive information in SharePoint. In this section, we will cover the basics of working with DLP policies.

Protecting Sensitive Information
At our organization, we take data loss prevention seriously. SharePoint is a powerful tool for sharing information, but it’s also important to ensure that sensitive information is protected. In this section, we will discuss how we protect sensitive information in SharePoint.
Sensitive Information Types
To protect sensitive information, it’s important to identify what types of information are considered sensitive. At our organization, we use Microsoft Purview Data Loss Prevention (DLP) policies to identify and protect sensitive items. These policies can use classification properties or item properties to identify sensitive information types, such as credit card numbers, social security numbers, and confidential company information.
Once we have identified the sensitive information types, we can take steps to protect that information. SharePoint provides several tools for protecting information, including:
- Permissions: By setting permissions on sites, lists, and libraries, we can control who has access to sensitive information.
- Encryption: SharePoint can encrypt data at rest and in transit, ensuring that sensitive information is protected.
- Data Loss Prevention: As mentioned earlier, we use DLP policies to automatically protect sensitive items across Microsoft 365 services and other cloud apps.
Compliance is an important consideration when it comes to protecting sensitive information. SharePoint provides several features to help us maintain compliance, including:
- Auditing: SharePoint can track and log user activity, allowing us to monitor who has accessed sensitive information.
- Retention Policies: We can set retention policies to ensure that sensitive information is retained for the appropriate amount of time and then disposed of properly.
- eDiscovery: SharePoint provides tools for eDiscovery, allowing us to search for and retrieve sensitive information as needed for legal or compliance reasons.
In conclusion, protecting sensitive information in SharePoint requires a multi-faceted approach that includes identifying sensitive information types, using information protection tools like permissions and encryption, and maintaining compliance through auditing, retention policies, and eDiscovery. By taking these steps, we can ensure that our sensitive information is protected and secure.
Data Classification and Labeling
Data classification and labeling are essential components of any data loss prevention strategy. By categorizing data based on its sensitivity, we can better understand how to protect it and prevent unauthorized access.
Understanding Sensitivity Labels
Sensitivity labels are a critical part of data classification. They allow us to categorize data based on its level of sensitivity, such as public, confidential, or highly confidential. Sensitivity labels can be applied to documents, emails, and other types of content.
With sensitivity labels, we can control who has access to sensitive information and how that information is handled. For example, we can restrict access to highly confidential documents to only a select group of users or require additional security measures, such as multi-factor authentication, before allowing access.
Mapping and Categories of Sensitive Information
To effectively use sensitivity labels, we need to understand the mapping and categories of sensitive information. Mapping involves identifying where sensitive information is stored and how it is accessed. This can include email, file shares, SharePoint sites, and other locations.
Categories of sensitive information can vary depending on the organization and industry. For example, healthcare organizations may have different categories of sensitive information than financial institutions. Some common categories of sensitive information include personal information, financial data, and intellectual property.
By mapping and categorizing sensitive information, we can better understand where our most critical data is located and how to protect it. This information can also help us develop policies and procedures for handling sensitive data.
Overall, data classification and labeling are critical components of any data loss prevention strategy. By using sensitivity labels and understanding the mapping and categories of sensitive information, we can better protect our data and prevent unauthorized access.
Preventing Data Loss in Microsoft 365
As businesses continue to migrate to the cloud, data loss prevention (DLP) has become a critical concern. Microsoft 365 provides a comprehensive DLP solution that can help us protect sensitive data from being shared or leaked. In this section, we will discuss how to prevent data loss in Microsoft 365.
DLP Rules and Actions
DLP rules are the cornerstone of our DLP strategy. We can create rules to identify and protect sensitive data across Microsoft 365 services, such as Teams, OneDrive, and SharePoint. DLP rules can be based on predefined templates or customized to meet our specific needs.
Once we have defined our DLP rules, we can take actions to prevent data loss. For example, we can block access to sensitive data, quarantine emails that contain sensitive information, or notify users when they are about to share sensitive data.
It is important to note that DLP rules and actions are not foolproof. Users can still find ways to circumvent them, intentionally or unintentionally. Therefore, it is crucial to educate our users about the importance of data protection and provide them with the necessary tools and resources to do so.
Teams and OneDrive DLP
Teams and OneDrive are two popular collaboration tools in Microsoft 365. They allow users to share files and communicate with each other in real-time. However, they also pose a risk of data loss if not properly managed.
To prevent data loss in Teams, we can create DLP policies that apply to Teams chats and channels. We can define rules to detect and protect sensitive information, such as credit card numbers or social security numbers. We can also block file uploads or restrict external access to Teams.
Similarly, in OneDrive, we can create DLP policies that apply to files and folders. We can define rules to detect and protect sensitive information, such as financial data or confidential reports. We can also restrict sharing or prevent users from downloading files to unmanaged devices.
In conclusion, preventing data loss in Microsoft 365 requires a multi-layered approach. We need to define DLP rules and actions, educate our users, and use the right tools and resources to protect sensitive data. By doing so, we can minimize the risk of data loss and ensure that our business remains secure.
