Hi Friends,
I am a graduate level Environmental engineer, We at our modeling group are planning to establish our own network. My Lab description . 2 Clusters with 7 nodes, 10 linux machine , 3 windows machine. 2 printers and 2x300TB storage device.
Our problem is secure our network from intrustion from external network ( we have exp it ). I need a model that will be able achive this goal.
I am planning to setup one Linux machine to act as router between the college network and our network . I also want to install DHCP server, FTP Server (for some external organisaton to access data ).
Kindly help me to get a prefect model for our network as we process and genrate gigs of data in our center .
eagerly awatiing for ur replies thanx in advance

AFAIK, if you trust the insiders then that router is the key. Either setup a separate firewall/IDS machine which will sheild the router or setup the firewall/IDS on the router itself. I would recommend the prior.

Wow and you're asking ilug-bom about this? :)

Dont u think that u should be hiring someone. Even if u do manage to setup some rudimentary protection, u need to have some understanding of networking and security to be able to monitor and understand what the logs throw at u. U are jumping in at the deep end of the pool.

If possible avoid ftp, use scp,sftp instead. Use ssh in place of telnet/rsh wherever needed. Harden your all cluster nodes. Put a firewall and IDS on linux server which will act as gatway to your cluster. Have some policies like 1. software upgrade policy: Patching up software on regular basis. 2. Cluster usage policy: Who and when one can use the cluster.
Select you distribution carefully. Personally I use and recommend debian because of its apt tools and debian social contract.
