2.3 Robust Programs

2.3 Robust Programs

1. A robust product can be one that doesn't break easily.

2. It's an operating system where an individual application can fail without it disturbing the system o applications to be robust

3. Data Validation - this is a check made by the computer to make sure the data entered is sensible or reasonable

   • The negative result is that it cannot check if it is correct or made a mistake on the user's part
     • An example: A phone has a 9 digit number but it asks for 11 and it then ensures that 11 has been typed in

4. Another method for validating and stopping attacks is to clean up the data that is inputted so the application is ready to use for the user.

5. Some people may try and get into the program and find clues out but the program is clever and adds little things in so the person trying to get in dosent know them.
