Software Heals Database Systems While They Work

Researchers at Pennsylvania State University said they have developed software that can repair a database that has been attacked, even as it continues to process transactions.

Scientists at the Cyber Security Group at Penn State's School of Information Sciences and Technology said the software can quarantine malicious commands sent to database management programs as it simultaneously repairs any damage done to the system.

The new software can be adapted for static repairs or for on-the-fly fixes that can unwind a chain of corrupted commands while the database continues to process transactions, researchers said.

Several large database software makers are beginning to offer their own self-healing systems. But none is as advanced as the Penn State research project, which represents the next frontier in database management software, analysts said.
