As Americans gear up for the holiday shopping season and Cyber Monday, the unofficial start of the online holiday shopping season on November 30, it is clear that Web site security plays a major part in consumers' purchasing decisions, according to a new poll by the National Cyber Security Alliance(NCSA)and Symantec [SYMC]. The poll, conducted by Zogby International, of more than 3,500 Americans found that online retailers will lose sales if consumers have concerns about a site's security.
