Any examples on how to use the Network Communication Protection Rule

Jump to solution

Does anyone have any real world examples on how they utilize the "Network Communication Protection" rule. 

 

I have been trying to figure out if we can use this rule to block data that was to leave from a secure vlan. It states that you must use content fingerprinting which is confusing me. Trying to utilize this rule but keep it from generating too many events.

Hi @twenden ,

Thank you for writing in here.

Content Fingerprinting is a quite good topic to learn about. I hope the below would be useful for you.

 

https://community.mcafee.com/t5/Enterprise-Documents/Manual-Classification-and-Content-Fingerprintin...

 

Small Summary: 

If you have created a classification for Application Content Fingerprinting and have mentioned the application as word.exe and have selected the file condition -> file extension as .docx. 

Then all files which you are creating/ saving by word.exe with file extension .docx will be processed by DLP and DLP creates fingerprint signatures for the contents of the files. 

And these fingerprint signatures are linked to the classification id(Classification name) in which you have created the Application content fingerprinting.

Now these files are called content fingerprinted files. So in NCPR rule you can use only content fingerprinted files.

 

Thank you.
