Which of the following methods would BEST help detect unauthorized disclosure of confidential documents sent over corporate email?

Show Suggested Answer Hide Answer
Suggested Answer: D

To detect unauthorized disclosure of confidential documents sent over corporate email, monitoring all emails based on pre-defined criteria is the best approach. This involves setting up automated monitoring systems that analyze email content, attachments, and metadata to identify any potential unauthorized disclosures. By defining specific criteria (such as keywords related to confidential information), organizations can proactively detect and prevent leaks. Requiring encryption before sending documents (option A) is important but does not address monitoring for unauthorized disclosures. Firewalls (option B) protect the network but do not specifically focus on email content.Reporting outgoing emails marked as confidential (option C) relies on user self-reporting and may not catch all incidents12.Reference:1(https://www.isaca.org/resources/isaca-journal/past-issues/2010/data-governance-for-privacy-confidentiality-and-compliance-a-holistic-approach)2(https://www.isaca.org/resources/news-and-trends/newsletters/atisaca/2020/volume-6/best-practices-for-privacy-audits)

Dude, can you imagine the IT guy's face if he had to read every single email? Option D is the only practical solution here.

Requiring all users to encrypt documents before sending could also help prevent unauthorized disclosure.

Yeah, it would be impossible for the IT guy to manually read every email. Option D is definitely the way to go.

Installing firewalls is important for overall security, but it may not specifically target unauthorized disclosure of confidential documents.

Option C sounds good, but what if someone accidentally marks an email as confidential? That could get messy. I'd go with D to be safe.

Haha, if I were a hacker, I'd just encrypt the documents before sending them. Option A is a total joke!
