When adjusting controls to increase security on messaging services, what is essential?

Adjusting controls to enhance security on messaging services requires not only technological measures but also operational policies that dictate how messages are handled. Establishing clear rules for handling messages is essential because it involves guidelines on how sensitive information is transmitted, accessed, and stored. These rules help ensure that all users understand the procedures for maintaining security, such as who can send certain types of messages, how to identify suspicious communications, and protocols for reporting breaches.

By focusing on rules for handling messages, organizations can create a structured approach that minimizes risks associated with human error and improves overall security posture. While encryption, compliance, and size restrictions are important aspects of messaging security, having robust handling rules is foundational to preventing data leaks and ensuring consistent application of security measures across the board.
