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.
