One of the hottest topics going today is security. So much so in fact that hundreds of Web sites, articles, ads, and books exist related to the subject. Many companies, consultants, and organizations are dedicated to helping protect you and/or your company's vital asset—data. It's not a downside by any stretch of the imagination; in fact, major online news sites, portals, and even government agencies have been invaded in one form or another, all the while employing some measure of security.
