Abstract: The present disclosure provides a computer-implemented method for extracting a target string excluding delimiter from a character string, which comprises a first step of loading a unit string into a 1-0 register; a second step of loading a delimiter boundary value into a 1-1 register; a third step of loading a value calculated based on the comparison result between the 1-0 register and the 1-1 register, into a 1-2 register; a fourth step of creating a mask by transferring a feature value of the value loaded on the 1-2 register to a second register; a fifth step of creating delimiter array by calculating offset of the delimiter based on the feature value; and a sixth step of extracting the target string based on the delimiter array.

Abstract: A computer-implemented method for responding to network threat includes receiving, by the threat detection module, security-associated data from a unit security system; generating, by the threat detection module, a ticket based on the received security-associated data; requesting, by the ticket management module, ticket analysis and response to the workflow module; calling, by the plugin program module, AIP of the unit security system or an external security service; and carrying out, by the workflow module, a task according to API communication with the called unit security system or the external security service. The task includes at least one of an inquiry task, a blocking task, an alarm task, and a follow-up action task. The inquiry task includes at least one of an inquiry about IP reputation, asset information, WHOIS, GEOIP, URL, HASH, sandbox, and prior information. The blocking task includes at least one of account deactivation, IP blocking, HASH blocking, URL blocking and domain blocking.

Abstract: A computer-implemented method of generating a file is provided herein having a column-oriented layout and including a file header and a data block. The method includes a step of inserting a field header into the data block and a step of inserting a block, which supports encoding of a variable type field value array, into the field header.

Abstract: A computer-implemented method is provided herein of generating a file having a column-oriented layout and having a file header and a data block. The method includes a step of inserting length information of an encryption vector into the data block; a step of inserting the encryption vector into the data block; and a step of inserting data array of the encrypted column after referring to the encryption vector.
