Problems solved by technology
[0003] In order to ensure the security of the network, at present, when an attack or suspicious attack is found in the network, it is necessary to search the network log and analyze various fields related to the attack in the network log, resulting in low analysis efficiency of the existing network security , the workload is very heavy
With the expansion of the network scale, various logs are massive, and it is almost impossible to perform correlation analysis according to traditional methods in the era of big data

The invention discloses a network security detection method and device, and relates to the technical field of information security. According to the invention, on the basis of a large data analysis technique, when a network threat is detected, the scope that the network threat involves can be rapidly and accurately determined. The technical scheme of invention is as follows: the network security detection method comprises the following steps: confirming network elements which perform network security analysis; acquiring network data, and associating all the network elements in the network data to obtain a network-element associated network; performing network security detection according to the network-element associated network. The network security detection method and the device, which are disclosed by the invention, are particularly suitable for the discovery process of APT attacks.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to a network security detection method and device. Background technique [0002] With the continuous development of information technology, the degree of informatization of human society is getting higher and higher, and the dependence of the whole society on network information is also getting higher and higher, so the importance of network security is also getting higher and higher. However, there are more and more attacks that threaten network security. For example, APT (Advanced Persistent Threat, Advanced Persistent Threat) attack, which uses advanced attack methods to carry out long-term persistent network attacks on specific targets. One of the attack methods that poses a great threat to network security. [0003] In order to ensure the security of the network, at present, when an attack or suspicious attack is found in the network, it is necessary to search the...
