Data Sources and Collection 

Identifying Relevant Data Sources for Fraud Detection in Financial Institutions 

1. Relevant Data Sources for Fraud Detection: Transaction Data: Information about financial transactions like the amount, date, location, and involved parties. Strange patterns in this data can signal potential fraud.  Customer Data: Details about customers such as their transaction history, credit score, and basic information. This helps spot unusual behavior.  External Databases: Databases containing known fraud indicators, like reported stolen credit card numbers or suspicious IP addresses. 

Methods for Collecting and Ingesting Data into Azure Sentinel

2. Ways to Get Data into Azure Sentinel: Connectors: Built-in tools in Azure Sentinel that connect with Microsoft services like Microsoft 365 Defender, as well as existing tools like firewalls.  Log Forwarding: Configuring systems and services to send logs directly to Azure Sentinel, both from Microsoft and third-party solutions.  Direct Ingestion: Adding data directly to Azure Sentinel using its REST API, which is useful for custom applications or sources without built-in connectors. 

Ensuring Data Quality and Consistency for Effective Analysis 

3. Making Sure Data is Good for Analysis: Data Validation: Checking that data is in the right format and within expected ranges. For instance, transaction amounts should be positive numbers.  Data Cleaning: Handling missing or inconsistent data by filling in missing values or making sure all data is in the same format.  Data Integration: Combining data from different sources in a way that makes sense and ensures everything matches up correctly, like making sure all timestamps are in the same time zone.
