My customer is considering installing a software product called "Secure IIS" from Eeye Security Systems. (www.eeye.com) It is a firewall for Microsoft Internet Information Servers which blocks malformed http attacks and 'get' requests that fueled the Code Red and Code Red II worms as well as many others. If I were to implement this I would need to install it on our Unity server and our Exchange server. Basically we need to know if this will work or would we be asking for trouble.<br><br>
