Study Notes
Al-Obaidy and Dual-Coding Programs
- Al-Obaidy programs create dual-coding, allowing information to pass through.
- These programs are an extension of Greedy Programs.
- A problem with Al-Obaidy programs is that viruses can interfere with systems accessed by multiple users, such as e-mail.
Security Concerns
- Invisible programs can hide in the operating system, allowing them to replicate and access computer resources without being detected.
- These hidden programs can slow down the computer and cause other problems.
Program Development Controls against Program Attacks
- Three key controls to prevent program attacks are:
Modularity
- Modularity is the process of dividing a program into subtasks called modules.
- Each module performs a specific function.
- This control helps prevent program attacks by limiting the scope of damage.
