Basically, I am looking for a reliable source of where I can start to learn to master this. While I can continue to work on this using perl, I am hoping there is something in .NET that supports this so that I can get better performance from compiled code.
Having programmed in C++ for so long, C# strikes me as trivially easy to use: the two are so similar, and the more advanced features of C++ don't seem to be there.
I am a "newby" only in the sense that normally I work on application software (such as statistical or data mining applications: I have programmed in FORTRAN and C/C++ for decades). I am just beginning to examine low level programming tasks
such as examining the lower OSI layers.
I have written some code aimed at one form of ecommerce fraud based on CGI programming in perl.
Maybe the question is naive, but I thought I might be able to get a clue about suspicious incoming traffic if I can compare the IP address information at the IP layer with the IP information in selected HTTP headers. I would guess that the first thing
to do is to be able to sniff incoming packets, and the next is to relate the incoming packets to the requests that have been made to our httpd server (I have access to both MS IIS and Apache, so whatever I do, I can host it on either, depending on what will
