There was a thread about blocking by country about a month or two ago, with some very good info. I tried it on one of my servers. I'm only blocking China, Russia, Taiwan, and the Koreas. Spam has dropped over 60% on this server. And the added benefit is that scans and ssh attempts etc, have dropped to a VERY manageable level. In fact, I'm now able to have the firewall send the alerts to my cell phone, which i was not able to do before, from being overwhelmed with alerts. I have no business dealings with anyone in those countries, so don't lose any sleep. As with everything in our field, is the risk worth whatever possible benefit? I guess it depends mostly on what your type of business is. ------------------------------------------------------------------------ This list is sponsored by: InfoSec Institute Need to pass the CISSP?
