The description about Pingware compared to ISS and it being more agressive, I would like to point out that the ISS being compared is the limited public version that is free. There is a commercial version of Internet Security Scanner available which has many more features and vulnerability checks than both the limited free demo of ISS and Pingware. There is more info at http://iss.net/iss Also, There are security FAQes (frequently asked questions) on http://iss.net/iss that deal with security with vendors, patches, anonftp, sniffers, and compromise. It is worth checking out. Thanks, Christopher -- Christopher William Klaus Voice: (404)441-2531. Fax: (404)441-2431 Internet Security Systems, Inc.
