Foil 7 Need for Security in Commerce - II

From Basic Principles of Java and Internet Security CPS616 Web Technologies -- Spring 98. by Geoffrey C. Fox


1 There is the usual fraud opportunities at both client and server side (fake customer or fake store) and these are already present in non Internet version
  • Security can reduce level of fraud and make this a viable business model
2 There is the possibility that merchant is attracting customers to site so that it can download applets and other Internet chicanery which can do bad things -- at least invade privacy
3 There is the possibility that credit card number is snooped and this is directly countered using encrypted transmission
4 Note we do not need a perfect system and commerce today builds in a certain fraction of loss due to fraud, bankruptcy etc.
