De CIA-triad is een fundamenteel concept in informatieveiligheid en wordt gebruikt als leidraad voor het ontwikkelen van beveiligingsbeleid, -praktijken en -technologieën om informatie en informatiesystemen te beschermen. Het helpt organisaties bij het nastreven van belangrijke doelen zoals het beveiligen van hun activa, het handhaven van vertrouwen en het zorgen voor de goede werking van informatiesystemen.
Confidentiality: This aspect of the triad is concerned with ensuring that information is only accessible to those who have the proper authorization. It involves measures such as encryption, access controls, and data classification to prevent unauthorized access and disclosure of sensitive information.
Integrity: Integrity in the context of the CIA triad refers to the accuracy and reliability of information. It involves protecting data from unauthorized modifications, alterations, or corruption. Techniques such as hashing and digital signatures are often used to verify the integrity of data.
Availability: Availability focuses on ensuring that information and systems are accessible and operational when needed. This involves implementing measures to prevent and mitigate disruptions, such as hardware failures, natural disasters, or cyberattacks. Redundancy, backup systems, and disaster recovery planning are common strategies to enhance availability.
