Enterprise security teams are increasingly being stretched by end users utilizing new, difficult-to-secure technologies. Consumer-focused cloud storage options like Dropbox and Apple's iCloud, for example, allow users to stores files and documents easily, making them available from any PC or mobile device.
But what if users store sensitive work documents in the cloud? Security professionals would ideally like to stamp out this behavior altogether, but if such services help users drive business initiatives, mounting a case against them can be challenging. Fortunately, security pros can offer users an extra layer of security thanks to AxCrypt, a free and open source encryption tool for Windows.
In this SearchSecurity screencast, Keith Barker, a Certified Information Systems Security Professional (CISSP) and trainer for CBT Nuggets LLC, provides an AxCrypt tutorial, showing how it makes simple file encryption possible for the average user. Barker first demonstrates how to encrypt a file. With AxCrypt installed, one simply needs to right click the document or file that requires encryption, choose the correct option from the subsequent AxCrypt drop-down menu, and input a passphrase. Users can also select the key-file option instead, though Barker warns that may not be wise because the data remains encrypted forever if the user loses the key-file.
Once encrypted, the associated icon of a file or document changes to that of the AxCrypt logo, signaling to a user that the data is now secured. To open the encrypted file, the user simply needs to double-click it and enter the correct passphrase, or point to wherever the key-file is stored; if any modifications are made to the data once opened, selecting "save" will automatically re-encrypt the file with those changes intact. AxCrypt also utilizes the respected Advanced Encryption Standard with 128-bit keys when securing files, giving users and enterprises piece of mind when sensitive corporate data is stored in potentially insecure ways.
