Which statement best captures the course review’s view of computer security?

### Why this is right Security needs ongoing attention because systems, users, and risks change. The review explicitly treats it as a process involving technology, people, and the environment, rather than as a one-time purchase. ### The concept Technical controls are only part of security. People must use them appropriately, and organizational and physical conditions can affect whether they work. Obscurity may hide details, but concealment alone does not reliably prevent misuse. ### The other options - **B. It is a product that provides permanent protection after installation.**: A product may supply a control, but it cannot provide lasting protection without continuing management. - **C. It depends only on keeping system details secret.**: This confuses security with obscurity, which is not a complete security process. - **D. It is needed only after a system has been attacked.**: Security is also preventive and ongoing; waiting for an attack leaves risks unaddressed. ### Terms - **Obscurity**: Relying on hidden or undisclosed details to make a system harder to understand or attack. ### Remember Treat security as continuing work across people, technology, and environment, not as a single installed product.
