An IT security manager has noticed a recent uptick in confidential information being leaked through casual conversations on the company's authorized instant messaging (IM) platform. While reviewing the IM security policies, what should the manager implement to reduce the risk of data leakage through IM chats?
Assign dedicated staff to manually review IM message logs for sensitive data
Configure Data Loss Prevention (DLP) policies on the IM system
Restrict file permissions for users on the network
Enforce end-to-end encryption for all IM communications
Configuring DLP policies to monitor and block sensitive information being sent through IM helps prevent data leaks. The IM system can be set up to detect and stop the transmission of predetermined sensitive information patterns. Use of encryption would make messages secure in transit but would not prevent employees from sharing sensitive information. Restricting file permissions is unrelated to IM conversations. Manually reviewing message logs is less efficient and might not effectively prevent leaks compared to automated DLP mechanisms.
