摘要:
A referer verification apparatus and method for controlling web traffic having malicious code are provided. In the referer verification method, whether a referer is present in a Hypertext Transfer Protocol (HTTP) packet is determined. If it is determined that the referer is present in the HTTP packet, Uniform Resource Locators (URLs) are extracted from a referer web page corresponding to the referer. The referer is verified based on a URL corresponding to a referer verification request received from a server and the extracted URLs. A Completely Automated Public Test to tell Computers and Humans Apart (CAPTCHA) verification procedure conducted by a user is performed based on results of the verification of the referer.

A system and method for detecting network intrusion by using a network processor are provided. The intrusion detection system includes: a first intrusion detector, configured to use a first network processor to perform intrusion detection on layer 3 and layer 4 of a protocol field among information included in a packet header of a packet transmitted to the intrusion detection system, and when no intrusion is detected, classify the packets according to stream and transmit the classified packets to a second intrusion detector; and a second intrusion detector, configured to use a second network processor to perform intrusion detection through deep packet inspection (DPI) for the packet payload of the packets transmitted from the first intrusion detector. Thereby, intrusion detection for high-speed packets can be performed in a network environment.

摘要:
A computer system includes a system part, a connector to which an external device is connected, a communication unit which performs communication with the external device, and a control unit which is connected between the connector and the communication unit to monitor a state of a predetermined recognition signal applied from the external device when the system part is in a standby mode. The control unit performs a predetermined function corresponding to the monitored state of the recognition signal. When the system part is in the standby mode, the system part may be switched to an operation mode based on the recognition signal from the external device. Additionally, a predetermined charging power is output to an external device in response to the predetermined recognition signal applied from the external device connected to the connector while the system part exists in the standby mode.

Disclosed are a cleaning robot system and its method for controlling which make it possible to reliably and quickly clean with the aid of the cleaning robot. The cleaning robot system comprises at least one external device each formed of an indicator and a virtual wall setting function, with the aid of which cleaning work can be performed by the unit of blocks about a cleaning area reference point, not leaving non-cleaned area behind. Since the access of the cleaning robot can be restricted by means of a virtual wall set by an external device, any damages of furniture due to a collision of the cleaning robot can be prevented, and the cleaning robot can be barred from escaping from the set cleaning area.

A scroll-type compressor has a scroll plate that is prevented from moving radially or rotating but may be axially displaced. The configuration includes a key and key way configuration and springs to axially bias one scroll plate away from the other scroll plate. The major components of the compressor assembly can be axially assembled.
