RE: adding another defence layer against viruses/worms

[<boaz.shunami () rsa com>]

Hi Juan,

I would advise your Client to either:

1. Have solid policy as to what sites are accessible/are not accessible
from his branches (can be enforced with bluecoat and the like...)
2. Segregate the network the branches have access to (kind of DMZ) from
his LAN using FW.
3. Give low level permissions to the branches on the core.

My 2c...

Thanks,
 
Boaz

Subject: adding another defence layer against viruses/worms

Hi all,

I'm doing some security consulting for a client. this client have around
30 remote branches connected to his core. the problem is that sometimes
the AV fails to detect new viruses/worms coming from those branches so
those viruses/worms mess up his LAN.another problem is that the the
client doesn't have much of control over the remote PCs in the branches.
so I thought about adding another layer of defence in which we will add
an IPS (which Ips detects also viruses/worms??) which will filter and
scan all traffic coming from the branches.

I just wonder if you guys agree with my suggestion.

any comments will be welcomed.

BTW,

any recomendations for the IPS?

thanks a lot 
juan
