Copyright(C) 1994 - 2009 Network World, Inc. http://www.networkworld.com/news/2009/101909-a-guide-to-windows-7.html Until now, Windows Vista was the most secure version of the Windows operating system. Windows 7 picks up where Vista left off, and improves on that foundation to provide an even more secure computing experience. Microsoft also incorporated user feedback about Vista to enrich the user experience and to ensure that the security features are intuitive and user-friendly. Here's a look at some of the more significant security enhancements in Windows 7.

Often it's the rule and not the exception. If you ever find yourself in a situation where you need a decently robust and full featured firewall and have a budget approaching zero, I have just the solution for you: SmoothWall Express.

Our focus today is on helping you WiFi better, even if it means doing less WiFi. James E. Gaskin 2009-09-02T12:00:00-04:00 http://www.networkworld.com/news/2009/082709-facebook-twitter-provide-sensitive-info.html Social networking services like Facebook and Twitter foster a false sense of security and lead users to share information which can be used by cybercriminals and social engineers. The very concept of social networking is based on connecting and sharing, but with who? Tony Bradley 2009-08-27T12:00:00-04:00 http://www.networkworld.com/news/2009/082409-the-art-of-creating-strong.html While security has never been more important than it is today, the fastest way for an IT professional to become the most despised person in the company is to start enforcing a strong password policy. A policy perceived as overbearing may cause people to write down their passwords on a sticky-note near their computers, circumventing its very purpose. Your policy will be ineffective if your users don't know how to create strong passwords that are easy to remember.

Twitter has taken some steps to mitigate the spike in traffic and ensure that the site is not knocked offline again, but some of those steps are having an impact on third-party tools that link to Twitter through API's (application programming interface). Tony Bradley 2009-08-10T12:00:00-04:00 http://www.networkworld.com/news/2009/080709-hardware-firewalls-bring-security-to.html Think your business is too small for a serious security appliance? The truth may surprise you. For less than $500, a simple unified gateway device can protect even tiny offices from the very real threats posed by malware and hackers. Robert Strohmeyer 2009-08-07T12:00:00-04:00 http://www.networkworld.com/news/2009/080709-twitter-ddos-attack-reminder-for.html Facebook, LiveJournal, and most visibly Twitter were sabotaged by a distributed denial of service (DDOS) attack. What's not clear is exactly why these sites were targeted. Current speculation is that the Koobface worm, whose name is a Facebook anagram, may be responsible for the attacks. A fresh wave of infections from a new variant of the worm supports this possibility. Let this serve as a warning that we can never remind our users too often about safe surfing practices. Michael Scalisi 2009-08-07T12:00:00-04:00 http://www.networkworld.com/news/2009/080709-learning-lessons-from-the-twitter.html Unless you have been living in a cave or off the grid for the past 24 hours or so, you are probably aware that Twitter experienced a two-hour outage yesterday morning as a result of a distributed denial-of-service (DDoS) attack that overwhelmed its servers. The same attack was also targeted at other sites such as Facebook and Google, but Facebook only experienced performance issues and Google seems to have been relatively unaffected. What can Twitter learn from Facebook or Google to help it handle future attacks without a site outage? Tony Bradley 2009-08-07T12:00:00-04:00
