Tencent Digital News (Compiler: Otsuka) For many years, to identify and defend against computer viruses, people mostly rely on traditional anti-virus software. Now things have finally turned a corner and a group of researchers are trying to integrate the above functions into the CPU.
Researchers from Binghamton University and the University of California Riverside are working together to advance projects aimed at achieving these goals. They intend to make changes to the CPU so that they can scan to find out what may be caused by malware.
Once the processor finds any suspicious activity, it will notify the security software installed on the PC, which will conduct in-depth analysis of the problem and take action when necessary.
In essence, the above ideas will use hardware to improve the efficiency of security software. Dmitry Ponomarev, who is responsible for the project, said that the modified microprocessor can identify malware by analyzing the execution of the program.
In trying to identify malicious behavior, the processor seems to take "low complexity" machine learning. Ponomarev said that monitoring by hardware cannot achieve 100% accuracy, so it is necessary to use software to complete a more comprehensive inspection and the latter will make a final judgment. If done entirely with software, the system is easily overwhelmed by the need to check all programs every moment.
The University of California, Riverside, has recently been exposed to newspapers, but last month's focus was on the flaws of the Haswell processor. The researchers found that the attacker could bypass a memory protection mechanism called "ASLR" to trigger stacks. Spill and attack.
However, the above research is expected to improve the CPU's performance in terms of security, no longer causing worrying loopholes.
