Cisco Cisco IPS 4255 Sensor

Because MySDN has been decommissioned, the URL in older versions of IDM and IME is no longer 
functional. If you are using IPS 6.0 or later, we recommend that you upgrade your version of IDM and 
IME.

You can upgrade to the following versions to get the functioning MySDN URL:

IME 7.0.3

IPS 7.0(4), which contains IDM 7.0(4)E4 

If you are using version IPS 5.x, you must look up signature information manually at this URL:
