As you may be knowing Gmail rolled out a labs feature some time back, Gmail users can soon expect a new addition to their accounts. The new addition is aimed at increasing the security and privacy of users. Soon Gmail will allow your to remotely log out of your account and also view the recent account activity so that you can track down if your account has been accessed from elsewhere, or if you are logged in from another computer or if someone other than you has accessed your account.

Consider for example that you log into your Gmail account at office and then leave in a hurry, forgetting to sign out, now when you log in again from your home or another computer you will be able to see that you are still logged in from your office computer in the Gmail footer (it shows "This account is open in 1 other location"). This is what it will look like:

You can then click the details link to get some more details about your account activity, clicking on details presents you with tables that will look like this:

You can now view two sets of information one regarding the concurrent session which gives you the details of all the open sessions, what is the IP address of the computer from where you have logged in, the access type. The other table is the recent activity table which shows you the IP addresses, access type and the time of recent logins into your account. You can thus verify that it was indeed you who has accessed the account recently and if you would like you can log out of all other open sessions (eg the one you created when you logged in at office) by clicking "Sign Out All other Sessions" button.

The new feature will be available shortly in the latest version of Gmail which is best accessed from Firefox and IE, no luck for Opera users again!

UPDATE: The features are live now, look at the footer of your Gmail page.

USB thumb drives are one of the most commonly used ways to transfer data if you happen to work across multiple computers. Lets just make the USB drives prettier, useful and secure.

1. Add icons and labels to your drive.

[autorun]

label = "<your name here>"

icon = "yourIcon.ico"

Save the file onto the root of your thumb drive and name it "autorun.inf", be sure to put the quotes or else it will be saved as a text file. Now Safely remove your USB drive and plug back in, the icon and name should appear in Windows Explorer if your did everything right. You can also automatically launch an application. If this is not the way you prefer to work use this neat application to generate the autorun.inf file automatically

2. Add a Start Menu to your USB drive

Moreover it lets you operate without leaving any trace what so ever on the computer, so you can be rest assured about your privacy and data

4. Write Protect your Drive

My USB drive has a write protect notch that prevents it from being written onto when plugged on a computer, this is important because if the computer you are plugging into is infected than it can readily infect your USB drive. However if your drive cannot be write protected then you can use thumbscrew. It makes anything connected to the USB non writeable until you are sure and want to make it writeable.

5. Make Autorun.inf read only and system file

Thumbscrew may prevent writing on USB devices but it has to be already present on the computer you want to plug your USB drive into, so if its not possible for one reason or the other then you should make sure that you have a custom autorun.inf file and that its read only and has the system file attribute set. This prevents malicious code from writing entries to your autorun.inf and thus even if your USB drive may have a virus it won’t actually run it automatically. So a little bit more protection but not fool proof by any means.

6. Hold down the shift key

If you suspect your USB drive may be infected but still you have to plug it in to scan and remove the infections, then when you plug it in hold down the shift key to prevent autorun if its not already disabled.

7. Encrypt your drive using Truecrypt
