Security Evaluation of Situational Awareness in Cyberspace Based on Artificial Neural Network-Back Propagation

Table 1

Situational awareness level in cyberspace.

Situation index values	0.0 ~ 0.15	0.15~0.35	0.35~0.65	0.65~0.85	0.85~1.0
Threat level
Description	Normal operation	The network is slightly attacked	Network operation is greatly affected	The network is attacked more seriously	The network is invaded by a large number of viruses
Description	Intrusion behavior	Loss is not big	System vulnerability is more	More seriously	Serious alert

Safe, medium threat, high threat, most threat, it indicates that the network is normal, and intrusion behavior does not exist.
