Best Way to protect our lan
Posted on 2009-04-07
Im using 5505 asa cisco pix firewall, and it is well configured, but also Im using VNC as remote desktop application and it is using by default the port 5900 to access my computers from external via internet over the real IPs.
So Ive been attacked till now 3 times on this port so I changed the port, and they attacked the VNC software even that it is protected by a password.
Is there any other way to protect my Lan from the external attack (software or hardware) and is there any software or hardware that monitor the traffic on the lan and the wan and between then (I know that we can monitor on cisco pix firewall but I need a more efficient monitoring tool)
P.S: I dont want to use ISA server as back end protection
