Opened: Jun 10, 2014
Severity: 3-Major


Update any "filter" field for signature-set changes other unchanged "filter" fields to default.


A User-Defined Filter Based Signature Set may not contain the expected signatures


REST Client is used to configure ASM and partial objects (only changed fields) are sent in a PATCH


When updating the object via a PATCH, send the fully populated object.

Fix Information

Filter fields that are not explicitly specified in the PATCH call are correctly left unchanged.
