A major security weakness is the lack of built-in hardware security features needed to isolate microcomputer users. It is difficult to prevent user programs from accessing or modifying parts of the operating system and thereby circumventing any intended security mechanisms. Without protecting the hardware, it is impossible to guarantee that any hardware-based security mechanisms have not been modified or removed. Software Security Considerations. Application software is completely dependent upon the security of the operating system residing on the system.
Application software is readily available and easily copied.
It is difficult to tell if a copy is legitimate. Your software will only be as secure as the media you store it on. Software should be centrally received and inventoried at the time of receipt. Original software should be kept under lock and key. Software should be installed by knowledgeable personnel and system configurations controlled.
