Generally, it may not be possible to prevent all risks to computer systems; but companies can implement procedures to protect their information system assets. As we mentioned earlier, frequent changes of passwords, ensuring that computer equipment and network devices and equipment are stored in environmentally safe buildings, and backing up company data daily, weekly, monthly depending upon the size of the company, and storing the backup data in another building. Storing the backup data in a separate building is useful should the main building is destroyed by fire or natural disasters.

What are other ways than those mentions already? Explain.
