IPS Update Function Becomes Unavailable (Example 1)

Publication Date:  2012-07-23 Views:  74 Downloads:  0
Issue Description
At a certain office site, the automatic and periodic UTM updating function is configured. After a certain period, the AV signature database is up-to-date, but the IPS signature database remains the same since the deployment.
Alarm Information
Handling Process
  1. Because the AV signature database is updated normally, the problem is not caused by incorrect
configuration of the automatic and periodic updating function. 
  1. The IPS configuration check result shows that the function of downloading and installing the latest
version is not configured. Different from the AV function, the IPS function requires user confirmation
before installation of automatically downloaded IPS updates.
By default, confirmation of automatic IPS installation is enabled. To validate an IPS version directly after its update, you need to run the undo update confirm ips enable command in the system view to disable confirmation of automatic installation.
Root Cause
  1. The automatic and periodic updating function is configured incorrectly.
  2. The IPS updates are downloaded but not installed.
If the customer needs the automatic update function, disable confirmation of automatic IPS installation during the deployment.
