Respond To Data Loss Prevention Alerts

Data Loss Prevention (DLP) Alerts

The DLP alerts will help you in your investigation to find the full scope of the incident and can also be generated from the Microsoft 365 Compliance or Microsoft Cloud App Security. With a DLP policy you able to:
  • Identify sensitive information across many locations, such as Exchange Online, SharePoint Online, OneDrive for Business, and Microsoft Teams.

  • For example, you can identify any document containing a credit card number that's stored in any OneDrive for Business site, or you can monitor just the OneDrive sites of the specific people.

  • Prevent the accidental sharing fo the sensitive information.

  • For example, you can identify any document or email containing a health record that's shared with the people outside your organization, and then automatically block access to that document or block the email from being sent.

  • Monitor and protect sensitive information in the desktop versions of Excel, PowerPoint, and Word.

  • Just like in Exchange Online, SharePoint Online, and OneDrive for Business, these Office desktop programs includes some capabilities to identify sensitive information and apply DLP policies that provides continuous monitoring when people share content in these Office programs.

  • Help users learn how to stay compliant without interrupting their workflow. 

  • You can also educate your users about the DLP policies and help them remain compliant without blocking their work. 

  • View DLP alerts or reports showing contents that matches your organization's DLP policies.

DLP Components

Sensitive information types

A sensitive information is generally defined by a pattern that can be identified by a regular expression or a function. In addition, it can also be identified by using the corroborative evidence such as keywords and checksums while also using confidence level and proximity in the evaluation process.

Microsoft 365 compliance comprises of a built-in Sensitive information types like Credit Card Numbers, Bank Accounts, and more, which allows you to create a custom sensitive info type matched on regular expressions, keywords, or an uploaded dictionary. 

Sensitivity labels

Sensitivity labels specify the classification of a document and they could be the terms like public, private, or classified. These labels also helps in applying more functionality to the documents, like encryption. The Labels are applied to the documents either manually or automatically based on the sensitive info type.

DLP Policy

A DLP policy contains a few basic things:

  • Where to protect the content- Locations such as Exchange Online, SharePoint Online, OneDrive for Business site, as well as the Microsoft Teams chat and channel messages. 

  • When and how to protect content by enforcing rules comprised of-                 

             1. Conditions that the contest must match before the rule is enforced. 

             2. Actions that you want the rule to take automatically when content matching the conditions is                   found. 
    
Cloud App Security file policy

File policies can be set to provide continuous compliance scans, legal eDiscovery tasks, DLP for sensitive content shared publicly, and many more user cases. But Cloud App Security can monitor any file type based on more than 20 metadata filters.

  To read part 1, please click  here To read part 2, please click  here Microsoft Monitoring Agent (MMA) MMA is used across multiple Microsoft solutions and has undergone a few name changes as its features and functionality have evolved. If it is being considered to be used, then following areas should be covered during a Microsoft Sentinel deployment project: Consider the timelines and the strategy for a migration to AMA (Azure Monitor Agent) before the MMA end-of-life.  Consider the central deployment and management methodology for MMA. Determine which endpoints are in scope for deployment as these affect the log ingestion volume significantly.  Azure Monitor Agent (AMA) Organizations with MMA as the main Microsoft Sentinel agent should start planning the migration to AMA as soon as possible to avoid a rushed migration. One of the main advantages of AMA is the ability to control the log collection policy centrally and apply different policies against different groups of computers, re

Various organizational units may require a level of access to specific dashboards or sets of data. Microsoft Sentinel offers the ability to assign table-level permissions and limit the level of access to the minimum required to perform requisite job functions.  Role-based Access Control (RBAC) Requirements Microsoft Sentinel offers an extensive list of Azure built-in roles that can be used to provide granular access according to the job requirements and permitted level of access. Some of them are various Microsoft Sentinel dedicated roles: Microsoft Sentinel Contributor- Can perform all engineering-related configuration, such as creating alert rules, configuring data connectors, and additional similar tasks.  Microsoft Sentinel Reader- Can query the log data stor
