Over the past two weeks Alien Vault has been notifying me of suspicious ip addresses scanning my web servers and exchange server. I have been blocking these addresses in my firewall as they come up. The 208. addresses are from oversee.net. The others are from China and other locations.
Does anyone have an explanation of why this is happening and if it is a serious threat?
Here are the ip addresses:
141.212.121.10
218.77.79.34
71.6.167.142
208.73.211.182
