rolled out a new security feature for Gmail
that can alert you when
it thinks someone else may be using your account. By using the IP tracking
feature that Google launched in July 2008, the new security feature will
display a warning if it detects that your account has been accessed from two different
geographic regions within a short timeframe.
Although the new feature isn't remarkably accurate (in the
US it only displays which state you are in), it can prove useful if an attack
comes from across the country or from overseas. Since there are plenty of
legitimate reasons for accessing an account from multiple locations, Google
doesn't lock you out of the account. Instead, it simply displays a warning
message and provides an easy way to change your password.
The message also provides detailed information so you can
see the latest account activity with information about the most recent access
points. If the access was legitimate, you can click "Dismiss" to
remove the message.
Recognizing security is also a high priority for businesses
and schools, Google plans to offer this feature for Google Apps in the future
after it has gathered and incorporated feedback.
