"defintions released" vs "extended version"

Created: 18 Apr 2013 • Updated: 18 Apr 2013 | 6 comments
This issue has been solved. See solution.

Could somebody tell me the difference between "defintions released" and "extended version" on this webpage here: http://www.symantec.com/security_response/definitions.jsp

For example:

Behavior-based protection says defintions released 4/10/13 and extended version 4/4/2013 rev. 11. The extended version is what is installed on my clients. When I run liveupdate on the SEPM it completes successfully saying no new updates found. I was under the impression that behavior-based protection (truscan or proactive protection) defintions are released daily. Has this changed in 12.1?

SEPM version 12.1.2015.2015

Client version 12.1.2015.2015

hi

 

File-based AV - Updated daily (typically three times a day Monday through Friday; one time a day on weekends).

So, the date on which the definitions get released are known as "Definitions Released" and the certified definitions releases are marked with a revision number (as there are 3 releases a day ) which are known as "Extended version".

http://www.symantec.com/security_response/definitions.jsp

Definitions Released: 3/25/2013
Extended Version: 3/25/2013 rev. 24
 

How often are Endpoint Protection definitions for IPS, SONAR, and Download Protection released?

Secondly, 

Network-Based Protection (IPS)- Updated on Weekdays (M-F - no releases scheduled for weekend or major holidays in the United States).

Behavior-Based Protection / Proactive Threat Protection - There is no set schedule.

Reputation-Based Protection (Insight) - Continually updated as it is a cloud based detection

The "Definitions Released" is the actual day they get released

The "Extended Version" is the date that will show on your client, ie. 4/17/2013 rev. 25

Any idea why for behavior-based the extended version is older than the defintions released date?

Definitions Released: 4/10/2013
Extended Version: 4/4/2013 rev. 11
 
(edit: spelling)

Those are for SONAR. They are not released as often as traditional AV signatures. Maybe once every week or two.
