I have a somewhat abstract network security question. I am newly administering networks on two separate locations with around 60 nodes each and have been working to enhance their network security. I know this encompasses too many areas to go into in a single topic, so I am looking for advice in the area of virus/spyware/malware etc. security.
Currently I have upgraded both networks to Symantec Endpoint Protection 11 for all servers and clients. I have been doing further research in virus protection and many experts recommend multiple solutions to better protect a network from attack. For instance, I recently ran into a couple virus attacks which completely bypassed Symantec Endpoint Protection and had to be found and removed manually. I know this is an issue which can never be protected against fully, but it seems there are solutions which will greatly enhance network security. One obvious addition is a hardware firewall for both networks which I am currently in the process of obtaining and installing. For this reason, I would like to narrow this focus down to purely the network software. My question is this&
What combination of network protection software would you recommend to be placed on both Server and Client machines? I.E., would you recommend using a malware and/or spyware product in parallel with Symantec Endpoint Protection? And even though I am utilizing Symantec Endpoint Protection currently, I would also like to hear if you have had better results with other solutions in network environments since others may be needing this and for my own reference when doing future upgrades. Also, please expound if you feel I have left off other key concerns pertaining to this focus.
My largest concern is experienced issues when combining products of this nature since many of their securities overlap and will cause conflicts, which I have seen many times in the past. Please add any knowledge you have as to why the proposed solutions are preferable to increase mine and other readers understanding in the area. Lastly, as is the case in nearly all organizations, cost is an issue. So if some of the ideal solutions are quite costly, a secondary recommendation for a similar but more cost effective solution would be greatly appreciated.
Thank you in advance for the help and I look forward to hearing from the experts in this area.
