Tricks of the Trade: Playing with DNS servers... some more

http://blog.sebastien.raveau.name/2009/02/playing-with-dns-servers-some-more.html

Tricks of the Trade. Tuesday, February 17, 2009. Playing with DNS servers. some more. Killing time in the metro by listening to podcasts of past security conferences, I got the idea of using DNS caches to check IP-spoofing capability. Now, the easiest way to check if you can send packets to the Internet with a fake source IP address would be with two computers (in different ASs), but that's no fun, is it?

Tricks of the Trade: December 2009

http://blog.sebastien.raveau.name/2009_12_01_archive.html

Tricks of the Trade. Sunday, December 6, 2009. On the legal uncertainty surrounding security education in France. By Cédric Blancher of EADS (in French sorry, automated translation to English here. Basically it discusses a highly subject to interpretation French law. That criminalizes informing people about dangers in Information Technology, and has me pulling my hair out to find interesting yet completely inoffensive. Stuff to tell you on Information Security.

Tricks of the Trade: April 2009

http://blog.sebastien.raveau.name/2009_04_01_archive.html

Tricks of the Trade. Friday, April 17, 2009. Just a quick tip before the big monthly blog post :-). Today I was asked by a friend if it was possible to assign different network interfaces to different programs for their Internet traffic. As bandwidth-intensive applications are often also the ones that don't really require privacy, one could imagine categorizing programs in a way so as to watch Internet TV over the Wi-Fi network while corresponding over the cable. Create a "wifi" user. Sudo -u wifi vlc.

Tricks of the Trade: July 2009

Tricks of the Trade. Sunday, July 26, 2009. From Maximum Risk To Maximum Security. Sorry, once again I have been too busy to work on my blog, notably with a prolific Paris Air Show. Last month, but I finally found some time here over the clouds somewhere between Vilnius and Copenhagen :-). For new readers, this is the follow-up to a first part entitled " Internet By All Means. In which I was describing how to maximize your chances to get a full and secure Internet access almost anywhere. 1 Protect your v...

Tricks of the Trade: January 2009

http://blog.sebastien.raveau.name/2009_01_01_archive.html

Tricks of the Trade. Monday, January 12, 2009. More on encrypted repositories and the usage of EncFS. Judiciously pointed out to me, synchronizing block-ciphered data (typically Rsync EncFS in aes-256-cbc mode, which I mentioned yesterday) will induce a slight overhead on the amount of transferred data, because of block padding. This means software like Rsync could indeed benefit from internal support for repository-encryption. From the University of California and IBM shows. Feature is enabled in EncFS,...
