Could you elaborate on the various types of messages that are used within the Financial Information Exchange (FIX) protocol? I understand that FIX is a widely adopted messaging standard in the financial industry, particularly for the electronic trading of securities. Are there specific message types designed for different types of transactions, such as orders, executions, or 
market data? And do these message types adhere to a standardized format, ensuring interoperability between various systems and participants in the market? Additionally, are there any security measures in place to ensure the integrity and confidentiality of these messages? I'm curious to learn more about how the FIX protocol facilitates efficient and secure communication in the financial industry.

    Admin messages are employed for transferring basic administrative information crucial to maintaining the operational integrity of the trading platform. Examples of admin messages include login credentials, heartbeat messages to confirm system connectivity, and requests to resend missing messages.

    In contrast, application messages are utilized for transmitting more substantive trading-related information. These messages encompass order requests, trade executions, and updates on the current state of orders.
