This book constitutes the proceedings of the 13th International Symposium on Stabilization, Safety, and Security of Distributed Systems, SSS 2011, held in Grenoble, France, in October 2011. The 29 papers presented were carefully reviewed and selected from 79 submissions. They cover the following areas: ad-hoc, sensor, and peer-to-peer networks; safety and verification; security; self-organizing and autonomic systems; and self-stabilization.

Protection of enterprise networks from malicious intrusions is critical to the economy and security of our nation. This article gives an overview of the techniques and challenges for security risk analysis of enterprise networks. A standard model for security analysis will enable us to answer questions such as "e;are we more secure than yesterday"e; or "e;how does the security of one network configuration compare with another one"e;. In this article, we will present a methodology for quantitative security risk analysis that is based on the model of attack graphs and the Common Vulnerability Scoring System (CVSS). Our techniques analyze all attack paths through a network, for an attacker to reach certain goal(s).

This book constitutes the refereed proceedings of the 8th International Conference on Autonomic and Trusted Computing, ATC 2011, held in Banff, Canada, September 2011. The 17 revised full papers presented together with 1 keynote speech were carefully reviewed and selected from numerous submissions. The papers address all current issues in autonomic architectures, models and systems, autonomic communications, trusted and secure computing, reliable, secure and trust applications.

Spar tid & Penge – skån miljøet er en opslagsbog til hjemmet med over 2.500 gamle husråd og gode ideer til en lettere hverdag. Bogen er forsynet med et meget detaljeret stikordsregister, så det er let at finde frem til de gode råd og tips, der findes om et bestemt emne. Bogen indeholder gamle, velafprøvede husmorråd, som har været brugt med succes gennem mange generationer samt en del nye, som er kommet til i de seneste år. Der er gode råd om personlig pleje, husapotek, madlavning, rengøring, tøjvask, strygning, syning, strikning, potteplanter, have, biler, cykler osv. Selvom der er rigtig mange ting i vores hverdag, der har ændret sig radikalt gennem de seneste hundrede år eller mere, så er der alligevel mange grundlæggende ting, som ikke har ændret sig ret meget. Vi skal stadig have mad hver dag, skal holde os selv, vores tøj og boliger rene og funktionsdygtige. Vi er gennemgående blevet mere miljøbevidste, og denne bog giver mange tips, hvordan du eksempelvis reducerer madspild og gør rent uden brug af farlige kemikalier. Du vil helt sikkert blive overrasket over at erfare, hvor mange daglige opgaver du faktisk kan klare, hvis du bare altid har eddike, citroner, bagepulver og klart opvaskemiddel i huset.
