Dropbox is still the most popular cloud-based file sharing and storage system, so its success and failures will inevitably signal how quickly the legal community warms up to the cloud.
Dropbox has recently come under scrutiny for a number of security failures. In response to breaches discovered earlier this summer, they have just introduced a new two-step verification on their accounts.
The two-step verification will be optional for users, and allows them to impose a new security code on top of passwords. The code is sent directly to a cell phone, and can be used whenever the account is added to a new computer.
Other changes introduced earlier this summer are security features to identify irregular activity, and a monitoring page to see where your account has been used.
It's not quite the level of security offered by data encryption, but hopefully it does prevent future breaches of data which could undermine confidence in cloud-based security.
