This question is in regards to the DLP endpoint or network DLP?
Sometime we use RegEx in DLP endpoint and Network DLP too but we normally verified with specific Algorith based on our requirements. If you can elaborate your request then I can try to help.
Thnks for Reply
This is regarding to DLP for endpoint.
We have created a regex for Visa Card in ePO console.After Creating expression we have test (Kept Validation Method Luhn 10) But some time it show Matches Found:1 and some time it show Validated found:1
So,I want to know in which sitatuation Incidence will genarate.
Alos how can I create a different types of expression for single Visa Card.
Ok this might help, after passing the Validation it will match the pattern and then it trigger event based on your policy configuration.
Have you tried to test this with any endpoint , I suggest try with multiple scenario by adding validated pattern and matching pattern with protection rule that will give better idea here.
Thanks for the conformation.
I like to know that how Regex works and how to find out regex pattern.
Is there any documentaton or any type of guide to make No. of Possible expression for pattern of Regex
I normally use Notepad++ with regex plugin, you can test the pattern and all , its easily available on their site.
For tutorial search in Youtube - detailed video's are there and refer Regexone.com site.
