Today's free eBook offer from Packt is Applied Network Security. It might become useful in scotty's fight against DoS attacks on OzBargain. A free Packt account is required to claim, access and download the eBook. As far as I know this is the first time this title has been offered free.
When you visit Packt's web page you will be offered Industrial Cybersecurity as today's free eBook, but it will say "This title is not available to claim on this day" after you pressed "Claim Your Free eBook". Afterwards Applied Network Security will be offered instead.
