Diagnosis of threat degree of IP addresses based on the generalized and regularized Mahalanobis distances

The domain name system( DNS) plays an important role in the internet, and maintaining its health and security is significant to the normal operation of the entire internet. To this end,we detect and shield the IP addresses that have potential threats to the name servers. We propose the generalized and regularized Mahalanobis distances to diagnose the threat degree of IP addresses. Both the methods efficiently solve the issue where the covariance matrix is singular. Real data analysis shows that the two proposed distances are very efficient in the diagnosis of threat degree of IP addresses.
