We have customers deployed with Cisco IP Telephony solutions. We need to address the security issues in CIPT environments. Went through the SAFE whitepapers on IPT Security. But I have the following to know:
1) Can we upgrade the OS of Call Manager with the latest MS security patches and hot fixes, as and when released from MS? Will there be any application problems? Should we wait for any Cisco notifications (if there are any) on such upgrades?
2) SAFE whitepaper suggests host IDS and host antivirus programs on the Call Manager? Any issues to be taken care of, before such implementations?
Any advise on the above is warmly appreciated, since it will help me win more IPT business in my accounts.
1.) You should only upgrade the call managers OS with the Cisco patches and hot fixes. The reason is that the Spirian install doesn't install the complete MS OS. Also many services that are not neccessary for CM are not installed or are disabled.
2.) IDS is a very very good idea. The HIDS product woks very well if configured correctly, McAffee and Symantec are both approved by Cisco as antivirus currently if I am not mistaken.
I recommend HIDS with all IPTelephony sales. You should work with the HIDS products and CM for a while to get familair with configurations that will maximize performance and security. If HISD is configured incorrectly you will potentialy create a DOS situation for your end users when you lock the server down.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
