|20150249589||METHOD AND APPARATUS FOR DETERMINING AUTOMATIC SCANNING ACTION - Disclosed are a method and an apparatus for determining an automatic scanning action. The method comprises: in a set period, collecting access request messages sent from a selected send end to a selected network server and access response messages returned from the selected network server to the selected sending end; equally dividing the set period into at least two set sub-periods, successively counting the number of the access request messages in each set sub-periods and determining a request credible value of the selected sending end; counting the number of response success messages and the number of response failure messages in the collected access response messages, and determining a request credible value of the selected sending end; calculating a general accessed value of the selected send end in the set period according to the determined request credible value, the response credible value, first weight, and second weight; and comparing the general accessed value with a first set threshold, and determining whether is the selected sending end performs automatic scanning This solution is more applicable and more accurate than the prior art.||09-03-2015|
|20130326627||APPARATUS AND METHOD FOR DETECTING VULNERABILITY - The invention discloses a vulnerability monitoring method for performing a vulnerability monitoring on a system in which data execution protection (DEP) is enabled, which method comprises the steps of: monitoring an operation with respect to the DEP; and considering that an action exploiting the vulnerability has occurred in the system when an operation to close the DEP is detected. The invention also discloses a corresponding vulnerability monitoring apparatus.||12-05-2013|
|20130276126||WEBSITE SCANNING DEVICE AND METHOD - The invention discloses a website scanning apparatus for performing a security vulnerability scanning on a target website, which apparatus comprises: a web page obtaining component obtaining current content and/or features of a web page corresponding to a link to be processed; a link processing component including a change judgment device for judging whether the web page corresponding to the link to be processed has been changed based on stored web page content and/or features corresponding to the link to be processed as well as the current web page content and/or features of the link to be processed; and a vulnerability detecting component for performing a security vulnerability detection on a web page corresponding to a link to be processed for which the web page has been changed. The invention also discloses a website scanning method corresponding thereto.||10-17-2013|
|20130227640||METHOD AND APPARATUS FOR WEBSITE SCANNING - Described is a website scanning apparatus comprising a policy analysis device for determining whether a link in a target website belongs to a known web application used by the target website. If the link belongs to the identified web application, then a vulnerability scanning is not performed on the link; a crawler device for obtaining the link content that the link points to; a web application identification device for determining whether the link belongs to a known web application; a full scan device for performing a full vulnerability scanning on a link determined as not belonging to the known web application; and a known web application vulnerability detection device for performing vulnerability detection for the identified web application according to known vulnerabilities to determine whether the known vulnerabilities exist in the website. A website scanning method employed by the website scanning apparatus is also described.||08-29-2013|
|20130219496||SECURITY CONFIGURATION VERFICIATION DEVICE AND METHOD AND NETWORK SYSTEM EMPLOYING THE SAME - The invention discloses a security configuration verification device for performing a security configuration verification on a network device, which comprises: one or more preconfigured scanning policies; a scanning policy generator, which selects a scanning policy from the one or more preconfigured scanning policies to generate a new scanning policy corresponding to the network device; and a scanner, which performs the security scanning on the network device with the generated new scanning policy and thereby performs the security configuration verification. The invention also discloses a corresponding security configuration verification method and a network system employing the verification device.||08-22-2013|
