CSM 4.2 ips signature

[rinoj2009]

                   hi CSM guys,

                                             I am a new user to CSM security manager . Currently we have asa 60 ASA 5505,5510 5520 and 5-10 IPS modules.

I would like to know CSM 4.2 version  would be good enough to manage these devices. What are the major differences b/w 4.2 and 4.3 versions

Also i got a info like there is bug in CSM 4.2 like  IPS signature   are not updated on a regular basis.

You are going to have to run CSM 4.3sp1, if you want to be able to support/manage the latest IPS software, version 7.1(6)E4
