I built network 'canaries', for lack of a better word, that do a couple things.
1) They emulate popular services, Web Server, FTP Server, MySQL server.
2) They provide you with information and alert you when other machines talk to it (for example, it will give you information from a POST request on a page that has a password field).
They are essentially network trapdoors that let you find people doing things they shouldn't on your network and are all precompiled ELFs, which make deployment super easy.I want this to provide me with real revenue (my 2016 goal). If you have input for me please let me know what you think.
