Which of the following best describes the goal of email security measures?

The goal of email security measures primarily revolves around preventing unauthorized access to sensitive information transmitted over email. This often involves implementing encryption, authentication, and access controls to protect data from interception, theft, or malicious activities such as phishing attacks. By ensuring that only authorized users can access email accounts and that the content of communications remains confidential, organizations can safeguard their information integrity and overall security posture.

While enhancing connectivity, optimizing performance, and facilitating communication are important aspects of email systems, they do not specifically address the protective focus that underpins email security measures. The core intent is to create a secure environment that mitigates risks related to data breaches and unauthorized access, making prevention of unauthorized access the most pertinent goal within the context of email security.
