IME 7.2.3 has the following new features:

Support for IPS 7.1(5)E4.

Policy groups and shared policies—You can now configure and deploy shared policies to multiple 
sensor and you can group policies for sharing. 

Currently the only policy that you can configure and deploy is the global correlation policy. 

Obfuscation Traffic/Attacks report—Contains statistics on suspect and explicit traffic obfuscation 
activity. It combines a top attacker report with a top event report. 

The IME Configuration pane has the following new features:

Signature threat profiles—In the IME Startup Wizard, you can apply a signature template to 
individual signature policies, which adjusts the signature coverage and response actions 
enabling the sensor to make better choices in various deployment and threat scenarios. 

Signature threat profiles are supported on the IPS 4345, IPS 4360, ASA  5525-X  IPS  
SSP, ASA  5545-X  IPS  SSP, ASA  5555-X  IPS  SSP, and ASA  5585-X  IPS  SSP.

Inspection load statistics—Displays the inspection load history across varying time periods.

HTTP advanced decoding is supported on the IPS 4345, IPS 4360, ASA  5585-X  IPS  
SSP, ASA  5525-X  IPS  SSP, ASA  5545-X  IPS  SSP, and ASA  5555-X  IPS  SSP.

Enabling HTTP advanced decoding severely impacts system performance.

The default value of the Cisco server IP address has been changed from 198.133.219.25 to 
72.163.4.161 in the Auto Update URL configuration. If you have automatic update configured on 
your sensor, you may need to update firewall rules to allow the sensor to connect to this new IP 
address.
