Mirant l'Internet Security Threat Report de Symantec
Per darrera de França i Alemanya... I Madrid, la ciutat europea amb més ordinadors infectats per un bot.
Madrid, Spain had the most bot-infected computers of any city in the EMEA region during the second half of 2006, accounting for six percent of the total.

Madrid, Spain had the most bot-infected computers of any city in the EMEA region during the last half of 2006, accounting for six percent of the total (table 4). Bot-infected computers are commonly used relay spam. Madrid ranked number one for spam zombies in EMEA, accounting for six percent of the world's 17 Therefore, it is reasonable to conclude that total. Spain has traditionally been a hotbed for spammers. that bot infected computers in Madrid are commonly being used to relay spam. With the prominence of bot-infected computers there, it is likely that it will continue to be a hotbed for spammers until ISPs in Spain develop more effective methods of controlling bot networks.

L'OLPC (One Laptop per Child) és un dels projectes més interessants dels últims anys, tant des del punt de vista social com del tecnològic.
Acaben de publicar el seu model de seguretat que canvia els estàndards habitualment utilitzats al món Unix, tot demanant a la comunitat especialitzada en seguretat la seva revisió:
System security on the One Laptop per Child's XO laptop 2
The Bitfrost security platform
The 1971 version of UNIX supported the following security permissions on user files:
- non-owner can change file (write)
- non-owner can read file
- owner can change file (write)
- owner can read file
- file can be executed
- file is set-uid
- These permissions should

We have set out to create a system that is both drastically more secure and provides drastically more usable security than any mainstream system currently on the market. One result of the dedication to usability is that there is only one protection provided by the Bitfrost platform that requires user response, and even then, it's a simple 'yes or no' question understandable even by young children. The remainder of the security is provided behind the scenes. But pushing the envelope on both security and usability is a tall order, and as we state in the concluding chapter of this document, we have neither tried to create, nor do we believe we have created, a "perfectly secure" system. Notions of perfect security are foolish, and we distance ourselves up front from any such claims.
Crec, sincerament, que aquest nou model de seguretat ràpidament evolucionarà de l'OLPC a la resta de sistemes, especialment aquells que estan pensats per a l'ús per part dels usuaris finals. Això fa que aquesta lectura sigui encara molt més interessant.
