AI Technical Summary

Technical Problem

Existing I/O control methods in endpoint security products suffer from low read/write control accuracy, leading to disk I/O read/write spikes that affect system disk performance.

Method used

By deploying a kernel extension mechanism at the driver layer of the terminal device, function calls for I/O operations in the kernel are intercepted, the target traffic value of the I/O operation is obtained, and compared with the baseline traffic value generated periodically to determine whether to allow the I/O operation to be initiated. This is combined with I/O flow control policies for precise control.

Benefits of technology

It improves the precision of I/O control, reduces disk I/O read/write peaks, and enhances system disk performance.
