Figure 8: Count of malicious websites versus indegree (left) and outdegree on the log-log scale (right)<br />

The average indegree of the malicious websites was 4.1 and the average outdegree of the malicious<br />

websites was 3.9. The standard deviation of the indegree and the outdegree of the malicious<br />

websites was 9.3 and 6.04 respectively. The average indegree was greater than the average<br />

outdegree of the malicious websites, even though the indegree computation is limited to the crawled<br />

dataset. This indicates that the malicious websites tend to have higher indegree over their outdegree.<br />

Series1 represents count versus indegree and count versus outdegree in the left and the right graphs<br />

respectively. The outdegree of the malicious websites was compared to the outdegree of the<br />

legitimate websites. We avoided the indegree in this study as the indegrees are limited to the links<br />

existing within the dataset. graph plotted with the outdegrees of the malicious and the legitimate<br />

websites is shown in Figure 9.<br />
