What is the first step to prevent credit card numbers from being sent externally via email?

• A. Implement stronger passwords
• B. Create a Data Loss Prevention (DLP) policy for Exchange
• C. Monitor all outgoing emails
• D. Train users on data sensitivity

Answer: (B)

Creating a Data Loss Prevention (DLP) policy for Exchange is the most effective first step to prevent credit card numbers from being sent externally via email. A DLP policy allows an organization to specify what sensitive information, such as credit card numbers, should be protected and under what conditions it can be sent or shared. When such a policy is in place, the system can automatically detect sensitive information in emails and take specific actions, such as blocking the email from being sent, notifying the user of the violation, or encrypting the email content. This proactive approach directly addresses the risk of sensitive data being accidentally or intentionally disclosed outside the organization. While utilizing stronger passwords, monitoring outgoing emails, and providing user training are all important components of an overall security strategy, they do not specifically target the automated prevention of sending sensitive data like a DLP policy does. Stronger passwords enhance account security, monitoring can help identify issues retrospectively, and user training raises awareness about data sensitivity, but they do not actively prevent the transmission of sensitive information in the way that a DLP policy can.
