Usability and Security of Personal Firewalls
Usability and Security of Personal Firewalls Almut Herzog^ and Nahid Shahmehri^ Dept. of Computer and Information Science, Linkopings universitet,Sweden {almhe, nahsh}@ida.liu.se Abstract. Effective security of a personal firewall depends on (1) the rule granularity and the implementation of the rule enforcement and (2) the correctness and granularity of user decisions at the time of an alert. A misconfigured or loosely configured firewall may be more dangerous than no firewall at all because of the user's false sense of security. This study assesses effective security of 13 personal firewalls by comparing possible granularity of rules as well as the usability of rule set-up and its influence on security. In order to evaluate usability, we have submitted each firewall to use cases that require user decisions and cause rule creation. In order to evaluate the firewalls' security, we analysed the created rules. In ad dition, we ran a port scan and replaced a legitimate, network-enabled application with another program to etssess the firewalls' behaviour in misuse cases. We have conducted a cognitive walkthrough paying special attention to user guidance and user decision support. We conclude that a stronger emphasis on user guidance, on conveying the design of the personal firewall application, on the principle of least privilege and on implications of default settings would greatly enhance both usability and security of personal firewalls. 1 Introduction In times where roaming users connect their laptops to a variety of public, pri vate and corporate wireless or wired networks and in times where more and more computers are always online, host-based firewalls implemented in soft ware, called personal firewalls, have become an important part of the security armour of a personal computer. -

2020-Floss-Roadmap.Pdf
-1- -2- Why do we need a 2020 FLOSS1 Roadmap? Based in Paris, Open World Forum (openworldforum.org) is a forum dedicated to FLOSS, its players and projects. OWF offers all contributors this open space in which they can express their own vision of FLOSS. 2020 FLOSS Roadmap is the Open World Forum’s main manifesto, and is designed to support discussions taking place during the different OWF seminars and forums. This is a prospective Roadmap, and a projection of the influences that will affect FLOSS between now (2008) and 2020, with descriptions of all FLOSS-related trends as anticipated by OWF contributors over this period of time. It also highlights all sectors that will, potentially, be impacted by FLOSS, from the economy to the Information Society. It is easy to find a wealth of writings on the subject of FLOSS contributed by various analysts, but this study represents a first, not just because of its inward looking vision of the future of the FLOSS Community itself, but also because it is the result of a collaborative effort by all OWF contributors. This first version of 2020 Roadmap is open to comment, and will be re-assessed annually during the OWF. Studies have been carried out in seven key areas: Theme 1: Public policies: promoting sustainable development of shared resources Theme 2: FLOSS: the key to future innovation and competitive differentiation? Theme 3: Ensuring sustainability for FLOSS developer communities and business ecosystems Theme 4: Technological and economic breakthroughs: challenge or opportunity for FLOSS? Theme 5: IT 3.0: towards new governance for information systems? Theme 6: FLOSS: a lever for employment and careers Theme 7: FLOSS in an Open World: Innovations and best practices from Brazil In the first section, we have summarized the discussions that took place during the study period, and this is followed by a special focus on Cloud Computing. -

Crippleware - Wikipedia, the Free Encyclopedia Page 1 of 1
Crippleware - Wikipedia, the free encyclopedia Page 1 of 1 Crippleware From Wikipedia, the free encyclopedia Crippleware is any product whose functions have been limited (or "crippled", thus the name) with the express purpose of requiring the user to pay for those functions (either paying a one-time fee or continually paying a service). Crippleware is also used to describe software that makes use of Digital Rights Management. Crippleware programs are usually free versions of computer programs that lack the most advanced (or in some cases, even crucial) features of the original program. Crippleware versions are made available in order to increase the popularity of the full program without giving it away for free. An example of crippleware is a word processor that cannot save or print. There are several types of crippleware programs. A crippleware version can be the full program with the features disabled; this type can be "unlocked" into a fully functional version of the software, usually via a serial number. A crippleware version can also be a special trial version of the program that does not even include the executable code for the disabled features. In this case, only users who buy a license are given access to another version of the program, which is fully functional. A third type is where the functionality of the software or hardware is permanently compromised from full functionality due to third party agreements. For something to become crippleware, it usually requires the manufacturer or author to take active steps to reduce the capabilities that the hardware or software could otherwise handle. -

Security Now! is brought to you by Astaro, makers of the Astaro Security Gateway, on the web at www.astaro.com. I smell a mod 4 episode. I do indeed. Leo Laporte here, Steve Gibson in Irvine, and it’s Episode 44. And as far as I can tell, that’s divisible by 4. Steve Gibson: That’s like a double mod 4. Leo: That’s a double mod 4. Steve: Yeah. Leo: So we get our usual 20 questions. Steve: It’s even mod 11. Leo: Mod 11, mod 4, mod 2, mod 0... Steve: Mod 22. Yeah. Leo: All right. You math showoff. Let’s get to the questions, unless there’s anything we want to cover from our last episode, where we talked all about ports.
