After using two-way communication between I/A's and PC or other dcs, security becomes a prominent problem, and efforts should be made to avoid unnecessary vandalism. Security is a very complex issue, please refer to the professional literature. I will not discuss in detail here, but only make some suggestions on the general principle:

I. When developing software on its own, security must be considered, including read and write access to control processor data, event handling of software (unexpected interruption of process, infinite loop of program, boundary processing, memory release, etc.) TCP/IP operation authority.

II. For professional software, due to its powerful function, when it is used, the unnecessary parts of the software should be closed, and the operation of the software should be password-authorized.

III. Security must be considered when establishing a communication program handshake mechanism.

IV. Strengthen the construction of relevant safety rules and regulations to avoid artificial damage.
