22. A system comprising: one or more processors; a memory configured to store instructions, which are executable by the one or more processors and include an analysis engine including one or more protocol parsers and configured to receive data including a first portion and a second portion, wherein the second portion of the data has a same protocol as the first portion of the data, and wherein the analysis engine does not analyze the second portion of the data; and a generic decoder operating according to primitives, wherein the generic decoder is configured to receive the second portion of the data from the analysis engine, assist the one or more protocol parsers by analyzing the second portion of the data for a signature, output a signal indicating the signature is detected in response to the signature being matched to the second portion of the data; and output a signal indicating the signature does not apply to the second portion of the data in response to encountering a token that does not match the signature.

The system of claim 22 , wherein the generic decoder is: coupled to a pre-developed protocol parser providing the second portion of the data to the generic decoder for analysis; and configured to use a syntax that also applies to the pre-developed protocol parser.
