Database security involves protecting the database from unauthorized access, modification, or destruction.
The security of information typically follows the CIA model, where CIA stands for Confidentiality , integrity, and availability.
Confidentiality requires that only authorized users have access to information in order to preserve the privacy of individuals, business intellectual property, and national security efforts. With the growth of social media and online business due to the Internet,
maintaining conconfidentiality involves using appropriate encryption techniques as well as user authorization, iddentification, and authentication procedures.
Integrity requires that only authorized users be allowed to modify data, thus maintaining data consistency and trustworthiness. If data is incorrect, it is no longer useful. Incorrect data can also be harmful to individuals (such as wrong data on a credit report) and organizations (such as invalid crucial reports).
Availability requires that information be accessible by authorized users when needed. Security attacks against an organization can cause business services to become unavailable, leading to violations of service level agreements that are critical to business operations.
