You should be aware of the most recent security threats so that you can most effectively secure and 
manage your network. Cisco Security Intelligence Operations contains the top ten intelligence reports 
listed by date, severity, urgency, and whether there is a new signature available to deal with the threat.

Cisco Security Intelligence Operations contains a Security News section that lists security articles of 
interest. There are related security tools and links.

Cisco Security Intelligence Operations is also a repository of information for individual signatures, 
including signature ID, type, structure, and description.

The following restrictions and limitations apply to Cisco IME 7.2.3:

You can use the IME to monitor sensors running Cisco IPS 5.0 and later; however, some of the new 
features and functionality in IME are only supported on sensors running IPS 6.1 or later.

IME 7.2.3 does not support Cisco IPS 4.x or 3.x sensors.

You can install IME 7.2.3 over all versions of the IME but not over IEV. All alert database and user 
settings are preserved.

IME 7.2.3 detects previous versions of IEV and prompts you to manually remove the older version 
before installing IME 7.2.3 or to install the IME on another system. The installation program then 
stops.

Make sure you close any open instances of the IME before upgrading to IME 7.2.3. 

If you are using Windows 7 or Windows Server 2008, uninstall any earlier version of the 
IME before upgrading. Otherwise, just upgrade from your current IME version.

Disable any anti-virus or host-based intrusion detection software before beginning the installation, 
and close any open applications. The installer spawns a command shell application that may trigger 
your host-based detection software, which causes the installation to fail. 

You must be administrator to install the IME.

IME 7.2.3 coexists with other instances of the MySQL database. If you have a MySQL database 
installed on your system, you do NOT have to uninstall it before installing IME 7.2.3.

For IPS 5.0 and later, you can no longer remove the cisco account. You can disable it using the no 
password cisco command, but you cannot remove it. To use the no password cisco command, there 
must be another administrator account on the sensor. Removing the cisco account through the 
service account is not supported. If you remove the cisco account through the service account, the 
sensor most likely will not boot up, so to recover the sensor you must reinstall the sensor system 
image.

The IME launches MySDN from the last browser window you opened, which is the default setting 
for Windows. To change this default behavior, in Internet Explorer, choose Tools > Internet 
Options, and then click the Advanced tab. Scroll down and uncheck the Reuse windows for 
launching shortcuts check box.
