ASIM Parsers

Correct Answer: A.

Option A is correct.

ASIM includes two levels of parsers: source-agnostic and source-specific parsers:

Option B, C & D are incorrect.

These parsers are invalid.

Reference:

ASIM stands for "Automated Security Incident Measurement" and is a framework developed by the US National Institute of Standards and Technology (NIST) for automated security incident detection and response. One of the key components of the ASIM framework is the parser, which is responsible for analyzing and extracting relevant information from security event data.

There are different types of parsers in ASIM, including source-agnostic, source-explicit, and source-gnostic. Here's a detailed explanation of each type:

1. Source-agnostic parser: This parser is designed to be independent of the source of the data it is analyzing. It can process data from different sources and formats without any modification. The source-agnostic parser does not require any specific knowledge about the format or structure of the data being analyzed.

2. Source-explicit parser: This parser is designed to work with a specific data source or format. It is customized to extract relevant information from data generated by a specific device, application, or system. The source-explicit parser is useful when dealing with large volumes of data generated by a single source.

3. Source-gnostic parser: This parser is designed to work with multiple data sources and formats. It can process data from different sources and formats without requiring specific knowledge about the format or structure of the data being analyzed. The source-gnostic parser is useful when dealing with a large volume of data generated by multiple sources.

In summary, all of the options listed in the question are valid parsers in the ASIM framework. Source-agnostic, source-explicit, and source-gnostic parsers have different strengths and weaknesses and are used depending on the specific needs of the organization.
