Time is always used as the most important parameter in the current network security visualization techniques on port scan.This makes the slow scan, the dynamic or random scan, concealed scan and spoofed scan hard to detect, and the detection results of the related security anomalies such as DDoS, worms, Trojans etc are bad too. Therefore, a novel network security visualization method for slow scan, concealed scan etc is proposed in this paper.

Considering the specialty of pseudo-random vector, a partial scan algorithm for BIST, which unifying the structure analysis and testability analysis, is presented in this paper. Then, the fault simulation experiments on ISCAS89 benchmark circuits by this algorithm is made, and the results, which made by the full scan algorithm and the partial scan algorithm only based on the structure analysis, is compared. The conclusion is achieved: for pseudo-random vector, compared with the full scan circuit and the circuit geted by partial scan algorithm only based on the structure analysis, the circuit geted by our partial scan algorithm can greatly reduce the test time with very close or even greater faults coverage and less area than the full scan.
