According to a one embodiment of the present invention, a method for collecting a website in an electronic device includes: step a of accessing a web server corresponding to a Uniform Resource Locator (URL) and receiving a website corresponding to the URL; step b of obtaining a first solution key based on a CAPTCHA solution model when CAPTCHA exists in the website; step c of transmitting the first solution key to the web server and receiving an authentication result; step d of recalculating the first solution key when authentication of the first solution key has failed and transmitting a CAPTCHA resolution request signal to a user terminal when the authentication has failed more than a preset number of times; and step e of receiving a second solution key from the user terminal, transmitting the second solution key to the web server, and crawling the website.

According to the present specification, a method for inspecting a high-speed network packet payload by a terminal includes: a step of receiving L7 (Layer 7) policy related to containers from a user; a step of extracting string patterns to be inspected for each of the containers on the basis of the L7 policy through a pattern compiler; a step of creating a deterministic finite automaton (DFA) on the basis of the extracted string patterns through the pattern complier; and a step of converting a state transition table of the deterministic finite automaton into a match-action table through the pattern compiler and storing the match-action table in an eBPF (extended Berkeley Packet Filter) map for a payload inspection engine.
