Operating system security
The goal of computer security is the protection of information stored on the computer system.
Information security is aimed at the following:
| Item | Description |
|---|---|
| Integrity | The value of all information depends upon its accuracy. If unauthorized changes are made to data, this data loses some or all of its value. |
| Privacy | The value of much information depends upon its secrecy. |
| Availability | Information must be readily available. |
It is helpful to plan and implement your security policies before you begin using the system. Security policies are very time-consuming to change later, so up-front planning can save a lot of time later.
