DLP and RMS: Key Differences Explained


Data loss prevention (DLP) and Rights Management Services (RMS) are two Microsoft 365 security solutions that can be used to protect sensitive data. However, they have different strengths and weaknesses, and they are best used in different scenarios. 

Data Loss Prevention (DLP) is a security solution that uses rules and policies to identify, classify, and protect sensitive data. It can be used to detect and prevent data leaks, both accidental and intentional. DLP can be used to protect data in a variety of locations, including email, documents, and files. 

Rights Management Services (RMS) is a security solution that uses encryption to protect sensitive data. It can be used to prevent unauthorized users from accessing or modifying data. RMS can also be used to control how data can be used, such as whether it can be printed or copied. 


Key Differences Between DLP and RMS 

Here are some key differences between DLP and RMS: 

  • DLP is more proactive than RMS. DLP can be used to detect and prevent data leaks before they happen, while RMS can only be used to protect data after it has been leaked. 
  • DLP is more flexible than RMS. DLP can be used to protect a wider range of data types and locations than RMS. 
  • RMS is more granular than DLP. RMS can be used to control how data is used in more detail than DLP. 

Examples of How DLP and RMS Can Be Used Together 

DLP and RMS can be used together to provide a more comprehensive solution for protecting sensitive data. For example, you could use DLP to detect and prevent data leaks, and then use RMS to encrypt the data that is leaked. 


Here are some specific scenarios where DLP and RMS could be used together: 


  • To protect credit card numbers in email: You could create a DLP policy that blocks the sending of credit card numbers outside of the organization. You could then use RMS to encrypt the credit card numbers in the email messages that are allowed to be sent. 
  • To protect confidential documents in SharePoint: You could create a DLP policy that prevents users from downloading confidential documents to unauthorized locations. You could then use RMS to encrypt the confidential documents in SharePoint. 
  • To protect sensitive data in Teams: You could create a DLP policy that blocks the sharing of sensitive data in Teams conversations. You could then use RMS to encrypt the sensitive data that is allowed to be shared in Teams conversations. 


Configuration Steps for DLP and RMS 

The configuration steps for DLP and RMS will vary depending on the specific scenario. However, some general steps that may be involved include: 

  • Identifying the sensitive data that needs to be protected. 
  • Creating DLP policies to detect and prevent data leaks. 
  • Creating RMS policies to encrypt sensitive data. 
  • Assigning DLP and RMS policies to users and groups. 
  • Monitoring and reporting on DLP and RMS activity. 

Eccentrix Training 


Eccentrix offers a variety of trainings on DLP and RMS. These trainings can help you to understand the different features and capabilities of these technologies, and how they can be used to protect sensitive data. 



Conclusion 

DLP and RMS are two powerful security solutions that can be used to protect sensitive data in Microsoft 365. By using them together, organizations can implement a comprehensive security strategy to protect their data from unauthorized access, use, or disclosure.

The Evolution of IT Training: From Classroom to Virtual Labs

Image
In the rapidly evolving world of information technology, the methods and modalities of IT training have undergone significant transformation. The shift from traditional classroom settings to virtual labs represents a pivotal change in how professionals prepare for the demands of the tech industry. This article explores the journey of IT training from its conventional roots to the innovative, flexible learning environments of today, highlighting the role of virtual labs in providing accessible, effective training solutions.  The Traditional Classroom Experience  Traditionally, IT training was predominantly conducted in physical classrooms. This setting offered a structured learning environment, direct interaction with instructors, and the opportunity for hands-on practice with hardware and software. However, the classroom model also presented limitations, including inflexible schedules, geographical constraints, and the significant resources required to update lab equipment to keep pace

Understanding IPSec Transport and Tunnel Modes: Securing Network Traffic

Image
IPSec (Internet Protocol Security) is a framework of open standards for ensuring private, secure communications over IP networks through cryptographic security services. IPSec operates in two distinct modes: Transport Mode and Tunnel Mode, each suitable for different security scenarios. Analyzing how each mode functions helps in determining the appropriate application to secure network traffic effectively.  IPSec Transport Mode  Functionality and Usage In Transport Mode, IPSec encrypts only the payload and ESP trailer of an IP packet, leaving the header untouched. This mode is typically used for end-to-end communications between devices, such as between a client and a server or between two servers in a private network. The main advantage of Transport Mode is that it provides a secure connection without altering the IP headers, allowing the packets to move seamlessly across the network without requiring adjustments by routers.  Operational Process Authentication and Key Exchange : Befor
