When sending data to a server-side container, what validation steps should be implemented to ensure data integrity and prevent malicious input?

To ensure data integrity and prevent malicious input when sending data to a server-side container, several validation steps should be implemented. First, implement input validation on the client-side. Before sending data to the server, validate the data on the client-side to catch simple errors and prevent obviously malicious input.
