It is increasingly being breached: numerous security hacks just this past month include the Colonial Pipeline security breach and the JBS Foods ransomware attacks where hackers took over the organization's computer systems and demanded payment to unlock and release it back to the owners.

Columbia Engineering researchers who are leading experts in computer security recently presented two major papers that make computer systems more secure.

"Memory safety has been a problem for nearly 40 years and numerous solutions have been proposed. We believe that memory safety continues to be a problem because it does not distribute the burden in a fair manner among software engineers and end-users," said Simha Sethumadhavan, associate professor of computer science, whose research focuses on how computer architecture can be used to improve computer security.

Computer security has been a long-standing issue, with many proposed systems workable in research settings but not in real-world situations.

The second paper that Sethumadhavan's team will present, No-FAT: Architectural Support for Low Overhead Memory Safety Checks, is a system that makes security checks faster with only a small - 8% - effect on the computer's performance which is 10x faster than current software technique for detecting memory errors.

The researchers found that when binning memory allocation is used by the software, it is possible to achieve memory security with little impact on performance and is compatible with existing software.
