System and method using user layer network solution

A non-transitory computer-readable storage medium storing instructions,

• wherein, the instructions, when executed by at least one processor, comprising processing circuitry, individually or in any combination, cause a system to perform operations comprising:
• determining, based on a user-layer network solution (ULNs) loader detecting an execution of an application program, whether a ULNs manager corresponding to the application program exists;
• loading, through the ULNs loader, the ULNs manager corresponding to the application program based on, as a result of the determination, the ULNs manager corresponding to the application program existing;
• transmitting, through a system call hooker, based on the application program calling a function related to a network, the called function to the ULNs manager based on the ULNs manager corresponding to the application program existing;
• and
• calling, based on the ULNs manager receiving the called function, the called function by changing a parameter of the called function to match a form of a corresponding function of a ULNs and transmitting, based on receiving a response corresponding to the called function, the response to the application program by changing the response to match a form of a library.

A system for using a user-layer network solution (ULNs), the system comprising:

• memory;
• and
• at least one processor, comprising processing circuitry;
• wherein at least one processor, individually or in any combination, is configured to cause the system to:
• determine, based on a ULNs loader detecting an execution of an application program, whether a ULNs manager corresponding to the application program exists;
• load, through the ULNs loader, the ULNs manager corresponding to the application program based on, as a result of the determination, the ULNs manager corresponding to the application program existing;
• transmit, through a system call hooker, based on the application program calling a function related to a network, the called function to the ULNs manager based on the ULNs manager corresponding to the application program existing;
• call, based on the ULNs manager receiving the called function, the called function by changing a parameter of the called function to match a form of a corresponding function of a ULNs and transmit, based on receiving a response corresponding to the called function, the response to the application program by changing the response to match a form of a library.
