About... 5-6 years ago I remember someone telling me about Rainbow books(I think that's what they where called). They where books about various computer security I think. He gave me an address to request them. Anyone know what I'm talking about? I beleive they where free. I had a few that I found, but have since lost them. Most likely out dates by now anyway. I did a search on google, but only came up with childrens books.
