Once More unto the Breach
4/13/2007
By David Nagel
"By following best practices, universities, as well as other large organizations, can reduce the likelihood of a data breach and the severity of damage when a breach does occur."
RSA's Parkerson offered these suggestions:
- Locate and classify the information in the protected classes in every system in which it is stored or communicated
- Determine whether having such data around for a particular application or system is really necessary; if not, lessen your risk by purging or truncating it.
- For the remaining data that must remain in full original form, acquire encryption solutions appropriate to the system type where the data exists (e.g. database encryption, storage encryption, laptop encryption, etc.).
- Ensure the solutions you acquire already include the necessary key management functionality, as managing keys on your own is too difficult.
The idea is to reduce the chances of your university having to do what UCSF had to do earlier this month: notify more than 40,000 people that their personal data had been compromised by one of its servers.
"Unfortunately, the damage is done," said BSI's DiMaria. "In conjunction with [notifying the public], they should immediately be reevaluating their processes (all inputs and outputs), not just technology (and we must recognize that they may in fact be doing this). While technological evaluation is important, the internal processes are equally important but far too often ignored. A full gap analysis against a recognized standard such as ISO 27001 is in order to identify opportunities for improvement. Using such a standard reduces the risk that something might be missed.
"Once these opportunities are identified," he continued, "immediate corrective action should be taken with a long-term plan following close behind to ensure the health of the system is continuously monitored and preventive actions are implemented on a regular basis."
We will keep you updated on developments in the UCSF incident as details become available. See the links below for more information.
