What might an insecure protocol allow that poses a security risk?

An insecure protocol is characterized by vulnerabilities that can be exploited by malicious actors. One significant risk posed by such protocols is the interception of sensitive data. When data is transmitted over an insecure protocol, it is often sent in plain text, making it easily readable to anyone who can capture the data packets during transmission. This could lead to the unauthorized access of confidential information such as usernames, passwords, financial data, and personal identification information.

In contrast, other options like enhanced connectivity, stronger authentication, or faster transmission speeds are not inherently related to insecurity. Enhanced connectivity does not directly imply security risks, and stronger authentication typically involves the use of secure protocols. Faster transmission speeds are advantages that could be offered by both secure and insecure protocols but do not contribute to a security risk by themselves. Thus, the primary threat that arises from using an insecure protocol is the potential for sensitive data to be intercepted, making it a critical concern for organizations managing data communications.
