Custom Signature- Stop Credit Card Information

Hi folks,

Great to be here!

Just installed IPS version 7.1; the environment is a financial institution servicing connection from third party and in-house user. I need to implement several custom signatures; prominent among these include sig to stop cardholder information (MasterCard, VISA etc string of card number) traversing the network.

Any ideas folks?

Thanks in advance

Daniel.

Custom Signature- Stop Credit Card Information

You cannot implement such signature which can crack down into secure tunnel, decrypt it and sense it as credit card info traffic.

You can generate custom

You can generate custom signature with text .

 

MASTER CARD

VISA 

 

and all such cards have some defined text which identifies them being mastercard or visa, then only you can filter them as you like .

 

This could be a hit and trial case but seems possible !

 

PS :  Normally DLP solution is implemented or SIEM solution is implemented to watch out for such things.
