The Internet has proven to be a vital communications medium for worldwide commerce, but as an open and unprotected global network it can also present a wide range of threats that can cripple any business organization. Several years ago, most Internet threats were relatively benign examples of a young adolescent’s technical expertise but over time they have evolved into increasingly sophisticated domestic and foreign attacks that are designed to capture financial, personal, or strategic business information. Threats now come in the form of deliberately malicious acts, and exploitative opportunities for hackers and/or organized crime. The impact is serious, and the landscape of victims is getting broader every day. In response, no organization can afford to have its networks remain unprotected.
