User-Defined Signatures (UDSs) are provided as an immediate solution to a security advisory. We write and test these signatures with the objective of a quick turnaround.
A UDS is intended to cover the known aspects of a threat and might not cover all variants. Sometimes, UDS releases might generate incorrect identification.
