  • Publication number: 20090122721
    Abstract: A hybrid network discovery method for detecting client applications. The method has the steps of: (a) applying test traffic packets to a network which is to be measured, and analyzing responses so as to check target nodes; (b) transmitting a protocol request packet to each of the checked target nodes; and (c) when the URL of the header of the protocol request packet coincides with a site for a specific application of the target node, extracting the URL and the IP address of the target node.

  • Publication number: 20090106843
    Abstract: Provided is a security risk evaluation method for threat management. According to the present invention, new threats or vulnerabilities for a network which should be protected (target network) are collected, and a threat management environment is assessed by checking whether or not to apply attack-attempt detection rules and vulnerability assessment rules for assets related to the threats or vulnerabilities. Based on the assessment result, the range and level of response are previously checked and complemented, and corresponding risk evaluation is provided. Therefore, the threat management environment can be managed effectively.

  • Publication number: 20090099885
    Abstract: A method for risk analysis using information asset modeling. The method has the steps of: (a) identifying an information asset which uses or provides a network service; (b) identifying a threat on the information asset through a computer network; (c) identifying a vulnerability of the information asset; (d) calculating an AL (attack likelihood) by using a CVSS (Common Vulnerability Scoring System) score obtained by converting a severity caused by a success of an attack on the vulnerability into a standardized value; (e) computing the value of the information asset so as to calculate an IM (impact analysis); and (f) multiplying the calculated AL and IM so as to determine an RL (risk level) for the information asset.

  • Publication number: 20080095187
    Abstract: Disclosed is a method for estimating an available bandwidth of a network link by transmitting small-sized probing packets using a time stamp function of an Internet control message protocol (ICMP) and using time information of the probing packet returned. According to the invention, even when the separate program or function is not activated in the router, it is possible to easily estimate and monitor the available bandwidth of the exterior network link connected to the network being managed. Accordingly, it is possible to operate the network more stably and to detect the abnormal sign of the network at early stage, thereby quickly coping with it. In addition, it is possible to prevent the excessive traffic or load from being caused in the network.
