  • Publication number: 20230036609
    Abstract: The present invention provides an event visualization device configured to generate one or more directed acyclic graphs (DAGs) that can be used as a basis for diagnosing whether a target network system has been hacked according to a plurality of activities records. The plurality of activities records pertain to an event cluster associated with a suspicious event category. The event visualization device performs a graph generating operation on the plurality of activities records in a recursive manner to generate a hierarchical directed acyclic graph (HDAG). The graph generating operation includes: interpreting an activities record into a target DAG, and performing a hierarchical partial order alignment (HPOA) operation on the target DAG and a reference DAG to obtain a merging condition of each node; and merging the target DAG and the reference DAG into the HDAG according to the merging condition.

    Abstract: The present invention provides a log classification system configured to perform a hierarchical similarity analysis operation according to a plurality of activities records to generate a discrete space metric tree, and perform a clustering operation on the discrete space metric tree to generate one or more event clusters associated with one or more suspicious event categories. The log classification system includes an output device configured to output the one or more event clusters to an information security incident diagnosis system, and allow the information security incident diagnosis system to calculate similar feature information and differential feature information of a plurality of activities records in the one or more event clusters as auxiliary information for diagnosing whether there are intrusions or abnormalities in a target network system.

  • Publication number: 20230022709
    Abstract: The present invention provides an information security incident diagnosis system for assisting in detecting whether a target network system has been hacked. First, a plurality of activities records of one or more computing devices in a target network system are collected. Then, a discrete space metric tree is generated according to the plurality of activities records, and a clustering operation is performed on the discrete space metric tree to generate one or more event clusters associated with one or more suspicious event categories. Each event cluster may form a guide tree corresponding to the event cluster through single linkage clustering analysis to indicate a merging order from high to low similarity. The merging order is used for recursively performing a graph generating operation to convert a plurality of activities records corresponding to the one or more event clusters into a hierarchical directed acyclic graph (HDAG).

  • Patent number: 11558352
    Abstract: A cyber security protection system includes a plurality of threat information updating devices; and a proactive suspicious domain alert system, which including: a domain information monitoring device; a domain information storage device; and a security threat analysis device, arranged to operably communicate data with the plurality of threat information updating devices through a network. If the domain information monitoring device detects that a domain mapping of a suspect domain is changed and the new domain mapping of the suspect domain points to a predetermined local address, the domain information monitoring device would further monitor a domain mapping variation frequency of the suspect domain. If the domain mapping variation frequency of the suspect domain exceeds a predetermined value, the security threat analysis device adds the suspect domain into an alert list to render the plurality of threat information updating devices to block their member devices from accessing the suspect domain.
