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. |
