Embodiment
[0046] see figure 1 Shown is a flowchart provided by the present invention. The implementation step S100 of the method is as follows:
[0047] S101. Perform a vulnerability scanning operation on network nodes and associated network nodes, obtain attack feature information of network vulnerabilities, and determine network vulnerability types of the aforementioned network nodes and associated network nodes according to the aforementioned attack features.
[0048] The network node refers to a terminal in a network environment with an independent network address and data processing functions, and the data processing functions include but not limited to the functions of transmitting data, receiving data and / or analyzing data.
[0049] The network nodes may be workstations, clients, network users, or personal computers, as well as servers, printers, and other network-connected devices. The entire network environment includes multiple network nodes, and these network nodes are conn...

The invention provides a situation awareness network vulnerability defense method, device and system, and relates to the technical field of network security. The processing method comprises the following steps: performing vulnerability scanning operation on a network node and an associated network node to obtain attack feature information of network vulnerabilities, and determining network vulnerability types of the network node and the associated network node according to the attack feature information; predicting the influence range of the network vulnerability type on the network node and the associated network node; and acquiring a time axis-based attack sequence executed by an attacker on the network node, and based on the attack sequence, calling a defense scheme matched with the network vulnerability type corresponding to the attack operation at the current time and the influence range information from a preset network vulnerability database of the situation awareness system according to the time axis information for defense. According to the method, the attack feature of the network vulnerability is obtained, the attack sequence based on the time axis is determined corresponding to the attack feature, and the attack operation at the current time is correspondingly defended.
Description
technical field [0001] The invention relates to the technical field of network security, in particular to a situation-aware network vulnerability defense method. Background technique [0002] In the existing technology, the situational awareness system integrates multiple data information systems such as anti-virus software, firewall, network management system, intrusion monitoring system, and security audit system to complete the assessment of the current network environment, and the future changes of the aforementioned network environment trend forecasting. [0003] In order to guarantee the ability to defend against network vulnerabilities in the network environment, network security and the ability to perceive potential network threats, the selection of a situational awareness system to achieve multi-system linkage defense can effectively improve the ability to defend against network vulnerabilities. [0004] In the actual process of defending against network vulnerabil...
