The three main goals of security are Confidentiality, Integrity, and Availability (CIA).
Confidentiality refers to protecting sensitive information from unauthorized access or disclosure. This includes preventing unauthorized access to data, systems, and networks.
Integrity refers to ensuring that information is accurate, complete, and reliable. This means that data must be protected from unauthorized modification, deletion, or other unauthorized changes.
Availability refers to ensuring that authorized users have access to the information they need when they need it. This includes ensuring that systems, networks, and data are available when needed and that any downtime or disruptions are minimized.
In summary, the three main goals of security are to maintain confidentiality, ensure data integrity, and provide availability of information to authorized users.
