Backups Question
Is it good practice to backup things like master passwords. If so, how/where can multiple copies be stored without storing them near the thing they unlock.For example, if I have a GPG key at home, I wouldn't want the symmetric key password at home too. (Is this even reasonable?)I can comfortably store a master password in my head but if I was to be really paranoid, I would worry about things like head injuries that give me memory loss.My issue is then; if I have forgotten my password, I may have also forgotten where it's backed up. This leads me to think that I would need to store the backup somewhere obvious and potentially insecure.For arguments sake, say that my threat model is being secure from the NSA, is it just best to have one master password remembered, without backups?

Best way to protect copyrighted work
Good morning all,I am an author of a training book or guide that I currently sell on Amazon. The training guide is a question and answer form guide to help students pass a particular exam. I was presented with an opportunity by a National training center. They proposed that I give them permission to use my training material, the questions that is, and in return they would have a link to where the students can purchase the full guide on Amazon. They would need access to my material in some format (MSWord) where they can copy and paste my questions. What would be the best way of sharing this material to prevent unauthorized access from copying? Please share some options. I was thinking of uploading to a secure server, creating a login and sharing that with the person.

Does banning IP-ranges with millions of IPs cause lots of extra CPU load?
This is for a Linux (no specific distro) server with Apache, MySQL, PHP. Some standard stuff. :) We're talking about low budgetservers. Lets say a VPS, with Dual CPU @ 1.6 GHZ, 2 GB RAM.IPTables, is that what most people use for banning ranges? I don't really know what most people use for this since it's normally nothing I work with. Please, tell me if there's a better way. I need to block the full server from these ranges. Not just 1 domains.If I for example want to ban: 101.16.0.0/12 Which is 1,048,576 IPs. Does this cause the server to spike up the CPU a lot more or is it a quick check for the server and just compare some numbers?What if I have ~20 more IP-ranges like it and it comes up to a couple of million, should any server handle this with ease?Another last question: Is it easier for the server to check the banlist if I only specify for example: "123...*"? I guess it doesn't have to calculate the IPs the same way then and only have to check the first 3 digits?I'm thankful for all the help I can get. :)
