Bitstream validation versus bitstream cybersecurity

Question

If we are talking about exchanging data between different applications or between an application and a human, the issue of data correctness arises. Usually, for modern computers, data is formed as bitstreams. To improve bitstream correctness we can apply validation or cybersecurity.

1. Do we know any more options?
2. What is the difference between validation and cybersecurity?

In this context, we must describe the difference between validation and cybersecurity. Both can be applied to improve bitstream correctness. My point is that 

1. validation ensures the bitstream is correct, functional, and compliant with appropriate domain-specific language 
2. cybersecurity protects the bitstream from threats caused by malicious users

Both processes are essential for the reliable and secure operation of digital systems, but they focus on different aspects of bitstream management. Validation ensures the bitstream works as intended, while cybersecurity ensures it remains secure from potential threats by applying cryptography measures.
