  • Publication number: 20260113302
    Abstract: Various embodiments of the teachings herein include a method for improving cybersecurity. An example includes: parsing a network packet to obtain a first network packet, wherein an operating system reads content in the first network packet sent by a controller for controlling operation of a first device; parsing attributes of the first network packet; filtering out malicious packets from the first network packet based on attributes of the first network packet, to obtain a second network packet; parsing the second network packet to establish communication with a first application layer in a second space of the operating system; and performing data conversion on the second network packet to enable the first application layer.
