What Malicious traffic is your Firewall Protecting you from?

This not an all inclusive list but typically represents about 99% of our daily unsolicited scans blocked by our firewalls as logged by Link Logger and port captures by PortPeeker or are ports we are commonly asked about.  The idea behind this is to give you an idea as to what the malicious traffic is that your firewall is protecting you from.  Of course everyone's environment might differ (for example some ISP filter out all TCP 445 traffic), but typically this is representative of what most internet users will see.  Don't believe us, turn on logging on your firewall and see for yourself......
