Hi,

How can I disable Port Scanning? I keep on receiving alerts on my firewall.

our Gateway has detected and successfully blocked an event that could have compromised the security of your network.
Please refer to your customer documentation for a description of the logged event.

Number of security log entries : 3

Security alert type : Port Scan
Protocol type : UDP
IP source address : 200.49.144.221
Time at last attempt : 1/4/10 01:49:08 PM
Number of ports that were scanned: 101
Highest port : 51896
Lowest port : 51887
51887 51888 51889 51890 51891 51892 51893 51894 51895 51896
(Only the first 10 ports are recorded.)

Thanks.

You cannot stop it since it is not you who is doing the Port Scanning. All you can do is block it using a firewall.

Be glad also that you're receiving such alerts because that means your firewall is working.

port scanning is the 1st step of hacking

u wont know that ur server/ip is alive.

if someone pings ur IP, it will just return a "time out".

disabling ICMP/ping won't stop anyone from scanning specific ports of your server.
