    Memory sticks have been branded as the latest security risk by
    security firm SecureWave, whose intrusion prevention technology can be
    used to control the use of the popular devices in corporate
    environments.
    
    The alleged risk here is that "many organisations run the risk of
    viruses and unauthorised software entering the network, as well as
    confidential data being removed through these small, yet powerful
    desktop devices."
    
    So flash memory sticks pose similar risks to those posed by floppy
    disks, and then some. SecureWave's concerns echo those of Websense
    which earlier this year warned that online storage sites provided a
    route to smuggle data out of organisations.
    
    But if people really want to smuggle data out of an organisation
    they'll always find a way; there's only so much technology can do. The
    application of technology has to be consistent with an organisation's
    overall security policy.
    
    There is a risk that USB devices could be used to bring viruses into a
    network. However since the main risk of viruses these days stems from
    email-borne nasties, desktop AV protection represent the most
    appropriate line of defence.
    
    In some instances, however, USB devices arguably pose their own
    distinctive security problem.
    
    SecureWave cites an incident where a Crewe estate agent plugged in her
    newly-purchased memory stick to her PC, only to discover the
    confidential medical records of cancer patients at a local hospital.
    
    So for many organisations, USB devices need to be managed properly,
    the thinking goes.
    
    
    Lock down
    
    SecureWave's argument is that you can't manage USB devices using Group
    Policy in Windows 2000/XP, but you can disable the USB ports using a
    third party tool called SecureNT from, you've guessed it, SecureWave.
    
    By default, SecureNT provides very strict security by disabling
    unknown devices, writing to CD Rom drives or plugging flash memory
    devices into USB ports. However, the use of some devices such as PDAs
    may be allowed by adding them to the list of user-defined devices.  
    SecureNT provides a degree of granular control over the use of
    devices.
    
    This could fit with a company's security policy. On the other hand,
    companies may decide that a networked computing route represents their
    best way forward.
    
    It all comes back to security policy.
    
    On a slightly related note South Korea's Samsung Electronics yesterday
    said it would be making and selling Sony Corp memory products for use
    in digital cameras and electronic organisers this quarter. According
    to Samsung, the memory stick market is worth $2.5bn a year worldwide.
