Categories of Security Threats
Security threats against an SMB's network fall into the following broad categories:
Information corruption
Information disclosure
Repudiation and lack of authentication and authorization
Denial of service (DoS)
These threat categories are neutral when it comes to the source of the threat, the motive behind it, and the manner in which the threat is executed. Consider a drastic example of information corruption: An SMB's database is destroyed, and there is no backup from which to restore it. From an operational point of view, it almost does not matter who performed the act of destruction, why, and how. It might matter from the legal point of view, but that is a separate topic outside the scope of this publication.
