Why Security?

What is the purpose/goal of security in an enterprise?

The principles of the CIA Triad form the foundation of security:

  • Confidentiality

    • Only authorized users should be able to access data.

    • Some information/data is public and can be accessed by anyone, some is secret and should only be accessed by specific people.

  • Integrity

    • Data should not be tampered with (modified) by unauthorized users.

    • Data should be correct and authentic.

  • Availability

    • The network/systems should be operational and accessible to authorized users.

Attackers can threaten the confidentiality, integrity, and availability of an enterprise's systems and information.
