A security administrator is deploying a DLP solution to prevent the exfiltration of sensitive customer data. Which of the following should the administrator do first?
A.
Block access to cloud storage websites.
B.
Create a rule to block outgoing email attachments.
C.
Apply classifications to the data.
D.
Remove all user permissions from shares on the file server.
Apply classifications to the data is the correct first step because it establishes a foundational understanding of what data is sensitive and needs protection. By classifying the data, the security administrator can ensure that subsequent DLP policies are effectively tailored to prevent the exfiltration of sensitive customer data, while minimizing unnecessary restrictions on non-sensitive data.
Applying a DLP solution to prevent data being 'leaked' out of the company, usually through email, USB or tools like Steganography.
Once installed the first thing he should do is create a rule to either warn or block email attachments. It's nothing to do with cloud storage or server file permissions and we don't need data classification for DLP to work (although it might be a nice option).
So you're gonna block all the end-users from sending attachments ? are you serious...
What should be done, is classify the files you have first then block the sensitive ones from being sent as attachments. Blocking everything doesn't make any sense in the context of this question.
