Universal Comprehension: Normalization and the Azure Sentinel Information Model (ASIM)

A persistent challenge in large-scale security operations is the inherent diversity of data sources. Azure Sentinel, by design, ingests telemetry from an incredibly disparate multitude of origins. Consequently, attempting to work with these various data types and their distinct table schemas concurrently necessitates an intimate understanding of each individual format. This often translates into the arduous and repetitive task of writing or adapting unique sets of analytics rules, designing bespoke workbooks, and crafting distinct hunting queries for every single data type or schema. This manual effort is inefficient and prone to errors.

The Azure Sentinel Information Model (ASIM) represents a pivotal innovation addressing this very challenge. ASIM provides a profoundly seamless experience for systematically handling diverse data sources by unifying them into uniform, meticulously normalized views. This standardization effort dramatically simplifies the analytical use of security data within Azure Sentinel workspaces through several key mechanisms:

• Facilitating Source-Agnostic Content and Solutions: ASIM’s core advantage is its enablement of source-agnostic security content and solutions. This means that a single analytics rule, workbook, or hunting query can operate effectively across data from various sources, as long as that data has been normalized to an ASIM schema. This vastly reduces the development and maintenance overhead.

• Simplifying Analytic Utilization of Data: By presenting diverse data in a consistent, normalized format, ASIM significantly simplifies the process of writing analytical queries. Security analysts no longer need to learn the intricacies of each original source schema, allowing them to focus on the threat intelligence and analysis rather than data manipulation.

• Optimized Query-Time Parsing: ASIM achieves its normalization through query-time parsing. This means the raw data is ingested as is, and the parsing to a normalized format happens dynamically when a query is executed. This approach minimizes the performance impact on the ingestion pipeline and storage, as the computationally intensive parsing only occurs when the data is actively being analyzed.

Fundamental Components of the Azure Sentinel Information Model (ASIM)

The robust architecture of the Azure Sentinel Information Model (ASIM) is composed of three interconnected and synergistic components, each playing a crucial role in its efficacy:

• Normalized Schemas: These schemas define standardized sets of predictable event types that serve as the blueprint for building unified security capabilities. Each schema rigorously delineates the specific fields that are representative of an event, prescribes a consistent and normalized column naming convention, and mandates a standard format for the values contained within those fields. This structured approach ensures data consistency regardless of its origin.

• Parsers: To facilitate the conversion of raw, source-specific data into the standardized ASIM schemas, Microsoft provides a collection of meticulously developed normalizing parsers. These parsers are readily deployable and can be found within the Azure Sentinel GitHub Parsers folder, specifically located in subfolders that commence with «ASim.» These pre-built parsers significantly expedite the normalization process for common data sources.

• Content for Each Normalized Schema: A critical benefit of ASIM is the availability of pre-built security content specifically designed to operate on normalized data. This includes a rich repository of analytics rules, workbooks, hunting queries, and various other components. The profound advantage here is that content developed for a specific normalized schema will function seamlessly across any normalized data source adhering to that schema, eliminating the cumbersome necessity of creating source-specific content for every single data type. This drastically reduces development effort and improves consistency across an organization’s security operations.
