Ebook: Cisco Network Security Little Black Book

A friend recommended this book to me as a cheap book that covered some of the higher-end issues with Cisco Security. I bought it and while I'm still working through it I'm really happy with it so far.

I should probably give this one star off due to some exceedingly long paragraphs (give me a break to catch my breath!) and a few small spelling errors but none of this stuff made me disappointed in the book which has good information, decent organization, and is clearly written by someone who knows his stuff.
