Discuss the goals of computer security system.

By Dipali Umre

Computer security has three main goals:

  1. Confidentiality – Keeping Secrets:
    • Think of this like a secret diary. You want to make sure that only authorized people can access and read it. Computer systems aim to keep sensitive information private, like your personal data, passwords, or classified business details.
  2. Integrity – Protecting Data:
    • Imagine you have a homework assignment saved on your computer. You want to ensure that nobody can tamper with or change your work without your permission. In computer security, integrity means safeguarding data from unauthorized alterations. It ensures that the information remains accurate and trustworthy.
  3. Availability – Ensuring Continuous Functioning:
    • Consider a vending machine. You want it to be available whenever you need a snack. Similarly, computer systems aim to be available and operational whenever you require them. Availability in computer security means preventing disruptions or attacks that could stop the system from doing its job, ensuring it’s always ready for use.
