Welcome to the Norton Community Forum!
I have seen this before with NIS 2011/2012 and thought that something was wrong.
After running different scans with different AV/Malware softwares that came up totally clean, I soon came to the realization that the various NIS Live Update components were simply upgrading the normal Firewall Configuration rules to keep up with changes in the method in which programs access the internet safely - an ongoing necessity in todays world where quality AV/FW suites constantly protect you.
So, no worries.
You can always look under History -> Security History -> Live Update and "drill down" to see what NIS components were actually updated.
Hope this helps answer your question.

What Norton product and version are your running?
I would run a Full System Scan and if all is well you should be fine, as long as these updated Program Rules are not causing any real problem for you. Live Updates are frequently being pushed through. Sometimes programs need to access the internet for these rules to activate and validate, I would think.
Hope this helps.

As programs get added, updated or change how they access the internet, the Norton firewall modifies the existing rules to accomodate the changes. If you look back through your logs you should notice many firewall configuration entries, as these happen all the time. They are normal and just a part of Norton's recordkeeping.

To confirm that all is well I'd suggest a full scan using your Norton product after running live update. Then I'd recommend you do a full scan from the desktop using Malwarebytes free scanner found here: http://www.malwarebytes.org/products/malwarebytes_
it's Norton compatible so keep it on the desktop and run it from time to time as a second opinion.
Hope this helps
PS: did you also check if there had been any pulse updates that might have added some information that caused the program to improve its firewall?
