Great book and great reference. It covers a wide range of topics and is very clear about each of them. Provides great example situations, real case studies, and ways to defend against SE attacks. Would recommend it to anyone!

I always use hotspot shield if I'm not using my server at home as a gateway. Just search it on google, it's free unlike other VPN software. The only thing I don't like about it is it doesn't run on linux. So, the only free solution for linux is using your own server, but otherwise, just use hotspot shield
