4. We are using Debian for advanced cryptographic programs like ISAAC - for random number generators (RNG). What's more it's used for simplier tasks like apache web server, mysql database, ftp. It's running on one 64bit Xeon(R) CPU E5-2620 station. Debian was chosen because of non vulnerability (malware&hacks) and great support.
