Any action that compromises the security of information owned by an organization.

On the other hand, it is quite difficult to prevent active attacks absolutely, because of the wide variety of potential physical, software, and network vulnerabilities. The broad service categories are: Cryptograpuy examples of confidentiality, integrity, crytpography, and authenticity requirements associated with the system.
