A network intrusion detection apparatus and method that perform Perl Compatible Regular Expressions (PCRE)-based pattern matching on the payloads of packets using a network processor equipped with a Deterministic Finite Automata (DFA) engine. The network intrusion detection apparatus includes a network processor core for receiving packets from a network, and transmitting payloads of the received packets to a Deterministic Finite Automata (DFA) engine. A detection rule converter converts a PCRE-based detection rule, preset to detect an attack packet, into a detection rule including a pattern to which only PCRE grammar corresponding to the DFA engine is applied. The DFA engine performs PCRE pattern matching on the payloads of the packets based on the detection rule converted by the detection rule converter.

An apparatus and method for manifesting an event to verify the security of a mobile application are provided. The apparatus for manifesting an event to verify the security of a mobile application includes a tester application production unit, a tester application execution unit, and a tester application daemon execution unit. The tester application production unit produces a tester application for testing an application to be tested based on application information which is extracted from the application to be tested. The tester application execution unit executes the application to be tested by manifesting an event included in the extracted application information, and extracts a user view object output to a screen of a smart device when the application to be tested is executed. The tester application daemon execution unit generates a touch event based on the extracted user view object, and performs a screen change.
