Guide to intrusion detection etc.

A "compilation of resources that explain what intrusion detection and prevention are, how they work, troubleshooting, configurations and more", by SearchSecurity.com and SearchNetworking.com: Intrusion Detection and Prevention Learning Guide.

Also, 2 blogs which look promising: Conspicuous Chatter and TaoSecurity.

One-time-pad encryption

How to unbreakably encrypt a message using a "one time pad" and the Vernam algorithm - it's surprisingly simple, but there's one big drawback: since this isn't public-key encryption, how do you get the one time pad to the person who is supposed to decrypt your message? You have to make sure that nobody except this one person gets hold of the pad. Moreover, you have to use a different pad for every single message.

File upload - success

I got around the problem (whatever it may have been) by going back to the original files and folders and creating 2 separate .zip files from them instead of 1. The drawback of this solution is that it isn't foolproof: the person who is supposed to download and unzip the stuff may easily put them in 2 different places, which will wreck the whole thing. Foolproof or internet-proof, which do you prefer?

Failed file upload (2)

Hmm ... Now, after 98%, I get a "Broken pipe" and "Remote site local filesystem disconnected" message. And I can't get over this point. What the heck is wrong here?

Failed file upload

We tried to upload a file of about 110 MB to the server - and, at the office, got nowhere. The connection broke so often that we just had to give up after reconnecting to the server for several dozen times. In the end, the connection broke after just a few seconds and this didn't get any better. Was it a problem with FileZilla? With Windoze? A (probably temporary) problem with the internet connection at the office? At home now, I'm trying again - and it goes through without a hitch. 93% of the file are on the server already.
