The invention discloses a network space asset real-
time perception and risk
early warning system based on a neural network, and belongs to the field of
network security. In order to solve the problems of poor real-time performance, low accuracy, incapability of
processing large-scale data, lack of adaptive ability and the like of a traditional cyberspace asset sensing and early warning method, a three-level collaborative module architecture is constructed and covers an asset sensing layer, a feature
processing layer and a risk early warning layer. The asset
perception layer collects asset information in real time by using a
hybrid detection engine and generates a
fingerprint vector; the feature
processing layer fuses multi-
modal data; and the risk early warning layer evaluates the risk and visualizes the
attack path. Meanwhile, a
reinforcement learning optimization detection strategy is adopted, a cross-
modal alignment
loss function is designed, and core algorithms such as space-time causal
convolution and a causal attention mechanism are applied. Practice of Guangxi
power grid company verifies that the asset state update
delay is reduced from 30 minutes to 2 minutes, the novel APT
attack detection rate is improved to 92%, the bandwidth occupation is reduced by 40%, and the
network security protection level is effectively improved.
