Data Integrity

Integrity is knowing that the message sent by a legitimate user is identical to that received by the system, and that its content has not been altered along the way. Clearly this is a significant security requirement, given the potentially disastrous effects of an intruder adding dangerous code to the end of an innocuous message. These "Trojan horse" attacks can frequently be devastating.

Encryption of the data, particularly strong encryption coupled with signed certificate authentication, provides data integrity by making it practically impossible for an intruder to modify a legitimate user's message. SunScreen^TM SKIP provides this technology in Solaris ISP Server.
