New MS Windows servers in the DMZ

Issue Symantec and Microsoft updates both depend on akamai and other types of services where the update programs recommend that dns based firewall rules be put into place.

From the Firewall team I understand that URI checking is a weak spot in checkpoint.
Wondering if anyone has good solutions for this? or can give me a list of options.

Thanks,
Mark

I cannot confirm nor deny.  Are there different methods for different versions ? I am sure it is at least a year or two out.

Generally anything above R70 has pretty good URI and IPS functionality.

There are a few options. Domain based objects and dynamic objects.
In general these options both bring with them a performance impact and are prone to fail with these web based services, like you said WSUS servers or i.e. virus scanner pattern updates.
If you implement domain based objects in the firewall like .akamai. or dynamic objects, that run a script you write to do the resolving, every time the rule is hit, the dns query or your script is executed.
As a rule of thumb, you move these rules as far back in your policy as possible, so they do not get parsed by legitimate traffic, still every illegitimate traffic will trigger the rule, and execute the query or your script. The performance impact can be severe under certain circumstances.
Othen than that, if your web server gets redirected/loadbalanced somewhere else by the destination servers, your updates will still fail.

My personal recommendation would be to use some kind of proxy solution like squid or bluecoat, if you do not trust your WSUS server or place them in a different DMZ and allow https to the internet.
