The first part of this article are here.
6. Prepare for distributed security.
During your initial strategy meeting, set aside time to discuss how you want to handle the many distributed security features in Windows 7. You’ll want to determine a course of action early in the project because those decisions will have a substantial impact on your test matrix.
First, consider whether you want turn on the desktop firewall. When OS-based desktop firewalls were first introduced in XP SP1, many organizations turned them off with a Group Policy and that was that. The firewall in Windows 7 is much more flexible and warrants reconsideration. You can turn off the firewall while the machine is connected to the domain and turn it on when the machine is connected to a home/work network or to the Internet. You can define granular exclusions, too. Try a mix of options with the first wave of pilot users; take their feedback, along with input from your security team, to make a final decision on firewall settings. They’re completely configurable by Group Policy.
Second, do you want to use AppLocker to restrict applications permitted to run on your desktops? AppLocker allows you to put together a whitelist of approved executables that you can select individually by file hash, in groups by location or in groups by publisher (that is, signed by the publisher’s certificate). Once configured, these rules are downloaded by Windows 7 clients running the Application Identity service. From that point forward, only the whitelisted apps can execute. All other executables are forced to sit on the sidelines, kind of like me during my high-school athletic career.
Because AppLocker permissions are applied via Group Policy, you can tightly target the rules to computers based on OU, group membership or WMI filters.
Sifting through a mountain of applications trying to determine which should be on an AppLocker whitelist doesn’t sound like much fun, but the situation shouldn’t come to that. Most line-of-business machines have a fixed and limited suite of apps. Start there. After all, if you can keep the night crews from plugging flash drives into your factory kiosk machines to run games rather than build widgets, you’ve solved quite a few operational problems. Deal with the back-office machines later. Read More»

Jason Before that the first and second part we continue to publish series of articles.
41. Go Live. Many applications installed on past versions of Windows have been removed. Starting with Windows 7, these applications (and a few others not typically installed with Windows) have been moved into the Live Essentials downloadable applications, at download.live.com. These applications include Messenger, Mail, Writer, Photo Gallery, Movie Maker, Family Safety and a few others.
42. Remove Apps. Although some applications have been moved off of Windows to become an optional download, other apps, such as IE8, Media Player, Media Center and DVD Maker are still included. In times past, especially when it came to IE, the applications were tied into the OS. However, in Windows 7 you can easily remove them if desired. Head to the Program and Features applet in Control Panel and select the “Turn Windows features on or off” link in the top left-hand corner. Then you can select the checkbox of the features you want to lose or add for your system. Read More»

Jason The purchase of a record-breaking windows 7 operating system to make it faster, better one day before the start of the second series I share with you.
21. Presentation Nirvana. Press Windows+P to access the new Presentation mode, and easily turn on your projector and laptop screen at the same time. No more messing with vendor-specific utilities and arcane keystrokes. (Windows+X accesses the Mobility Center, with additional presentation options.)
22. Cut the Clutter. Press Windows+Home to minimize all but the current window, removing background clutter and letting you focus on that report your boss has been bugging you about.
23. Be a Mouse-Click Administrator. Windows 7 makes it easy to gain admin rights with a keyboard shortcut. Click on Ctrl+Shift on a taskbar-locked icon, and voila! You’ve launched it with appropriate admin rights.
24. Faster Installations. If your computer is capable of booting from USB, try this: XCopy the Windows 7 installation DVD to a sufficiently large USB drive, boot from that drive, and install Windows from there. It’s faster than a spinning platter.
25. Burn Discs with a Click. Or two; double-click an ISO file to burn it to your CD or DVD writer. Read More»

Jason The revised Vesik method involves typing nonsense characters into a password input box when using a public PC and then rearranging some of the letters to form your actual password with the mouse. If the PC contains a hardware keylogger or is infected with a software keylogger, rearranging a password in this way will usually suffice to obscure your credentials. Most hackers will concentrate on the 99% of users who type in their passwords at Internet cafés in the usual way.
One proposal sent in by many, many, many readers was a variation on a single theme. Namely, keep your sign-in information on a USB flash drive or memory stick, then copy and paste the info into the appropriate fields when you’re required to use a public PC or other unsecured computer.
Unfortunately, many keyloggers capture any information you place into the Windows Clipboard. I tested the copy-and-paste technique using the All In One Keylogger from RelyTec. (For more info, see the vendor’s site.) The program easily captured the sign-in IDs and passwords entered, whether I used the standard menu options (Edit, Copy and Edit, Paste) or the keyboard shortcuts Ctrl+C and Ctrl+V.

Have you ever tried to share files on your home network but found that dealing with folder permissions and user accounts was just too frustrating? You aren’t alone; the process can aggravate experienced IT pros and home enthusiasts alike. Just imagine how your parents feel when they try to share files across their home computers.
HomeGroup helps simplify file and printer sharing among computers that run Windows® 7 on your home network. Domain-joined computers can also join your homegroup, so you can bring your work laptop home and access your music collection. You can set up HomeGroup as easily as you log on to most password-protected Web sites. HomeGroup is a feature of Windows 7, and Home Premium or better is required to create a HomeGroup.
The step-by-step instructions in this walkthrough provide a brief tour of the new HomeGroup feature in Windows® 7. These instructions assume that you have two computers running Windows 7 and at least one computer is running Windows 7 Home Premium or better on the same network, and neither computer is already a member of a homegroup or are joined to a domain.

This tips is dedicated to all the firefox lovers out there who are struggling with slow speed firefox and crashing issues. Firefox is one such browser who has been my favourite since the time I first tried to use Firefox 1.5 from that I have moved to firefox and it is the primary browser for me till this date, there are several improvements that have been done now the latest version of firefox is Firefox 3.5 which I using right now.
With time there are lot more things that have been changed in firefox which has made it a better and secure browser than before to use, but with new cool browser from google called google chrome which is far more faster than firefox in operation people has started moving towards google chrome because it is faster and easier to understand and use.
But as we all know google chrome is in development stage so it cannot provide some good features which are there in firefox like and it does not support much more extensions which provide great functions in firefox.
But new version of firefox 3.5.x crashes so often and does not even closes when you shutdown the firefox window as reported by some users it keeps running in the background and does not allow you to launch new firefox session. Read More»

You can see whether your current passwords you do use more than one, right? are rated “strong” by using Microsoft’s online Password Checker. I bet you’ll be unpleasantly surprised by the results.
The three keys to strong passwords are length, randomness, and use of different types of characters. Each additional character multiplies the potential combinations a brute-force attack must try.
Random passwords use upper- and lower-case letters, numbers, and symbols. When at least three of these four categories are used, an eight-character password should suffice in most instances. According to the FrontLine security site, such a password would take a century or more to crack by a hacker using a single PC. The eight-character standard is also the minimum the Microsoft Password Checker deems “strong.” Of course, the more characters in your password, the safer you’ll be.
If you wish to create your own password, use a sentence or phrase you can recall easily and then tweak it for each account. Read More»

The disclosure of a back door allowing bad guys to repeatedly guess Gmail passwords should remind us all to protect our accounts with long and strong character strings.
There’s a straightforward way to protect your online accounts use signin phrases that are easy for you to remember but hard for others to guess.
The latest vulnerability affecting Gmail accounts was recently revealed by security researcher Vicente Aguilera DĂaz in a posting on the Full Disclosure security list. (Aguilera previously revealed a Gmail flaw known as session-riding, which Google subsequently fixed, as reported by WS contributing editor Scott Spanbauer)
According to Aguilera’s new security alert, Google allows anyone with a Gmail account to guess another Gmail user’s password 100 times every two hours, or 1,200 times per day. No “captcha” keeps hacker bots from guessing passwords in this way. Worst of all: If a hacker controls, say, 100 Gmail accounts, 120,000 guesses can be made per day. Because Gmail accounts are free, many hackers control far more than 100 accounts, of course. Read More»

1. Delete items from address bar history
While it’s very handy to have your recently visited pages autocompleted as you type, it’s not always desirable. Go to the address bar (Ctrl-L), start typing an address, and the drop-down menu will appear with the URLs of pages you’ve visited. You can highlight and delete these at will, for maximum privacy.
2. Protect your PC from malware
You don’t have to visit the seedy side of the web to pick up a virus – even the best social networking sites regularly host all kinds of malware. But you can reduce the chance of infection by installing NoScript. This handy add-on blocks Javascript, Java, Flash and other executable content from running unless you explicitly allow it, and is a great way to keep yourself safe online.
3. Speedily search for images
Browse Google images and your results are split into blocks of 21. But use CoolIris and you’ll get all your results displayed on a 3D photo wall, a much faster and easier way to find the images you need. It only works with some sites, unfortunately, but as these include Google, Flickr, Picasa, Yahoo, Photobucket, Facebook and MySpace then you’ll still have plenty to browse. Especially as it searches and displays YouTube videos, too. Give it a try. Read More»

Symantec Security Response encourages all users and administrators to adhere to the following basic security “best practices” to prevent the virus attack to your computer:
1. Use a firewall to block all incoming connections from the Internet to services that should not be publicly available. By default, you should deny all incoming connections and only allow services you explicitly want to offer to the outside world.
2. Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
3. Ensure that programs and users of the computer use the lowest level of privileges necessary to complete a task. When prompted for a root or UAC password, ensure that the program asking for administration-level access is a legitimate application. Read More»
