I have a network with 10 computers with 2 NAS drives. All connected to a Linksys router that is connected to the internet. All computers have Norton Internet Security 2009 runnning. What else can I do to make the network more secure and protect the data (Wireless on router is turned off)? I have sensitive data on the NAS drives and it would be detrimental if the data is compromised.
Would having a Windows 2003/2008 Server make the network more secured (i.e. connect the server to the router then to the rest of the network)?
