We can also define information security as the set of measures taken to prevent information from being harmed in the wrong hands.

Principles of Information Security: The CIA Triad

Confidentiality: Ensures that information is accessible only to authorized individuals and prevents others from viewing it.

Integrity: Means that information remains accurate and unchanged, preventing it from being accidentally or intentionally altered.

Availability: Ensures that information is easily accessible to authorized users when needed.

Information security encompasses the protection of both physical documents and electronic data. This includes a wide range of measures, from encryption techniques to access control systems and antivirus software.

Today, especially with the widespread use of the internet, information security is of vital importance for both individuals and organizations.
