The authors assessed the "Fortune 500" corporations' retail e-commerce security to identify their strengths and weaknesses for improvement. They used online content analysis, information security auditing, and network security mapping for data collection and analysis. The findings indicate that most sites posted security policies; however, only one third stated what security measures were in action. Second, all of the sites secured "My Account" login with secure Sockets Layer Encryption, but only 16% limited 3 attempts of login access. Third, although the sites had most of their Internet ports filtered or behind firewalls, nearly one third of the sites' computer operating systems were detected from the few open ports.
