An organization is deploying XSIAM and needs to integrate with a custom internal application that generates critical audit logs in a proprietary JSON format, accessible via an authenticated REST API. The API only allows fetching data in chunks based on a timestamp range. The XSIAM team wants to ensure continuous and complete ingestion of these logs. Describe the essential components and logic required for a robust XSIAM integration for this scenario, including any specific XSIAM features that would be leveraged.
Correct Answer: A
Option A provides the most robust and complete solution. A dedicated XSIAM Data Collector is needed to establish connectivity and process the data. The 'stateful pulling mechanism' with an execution script is crucial for managing the timestamp-based API calls, ensuring no data loss and handling pagination/errors. A custom parser within XSIAM (or pre-processing in the script) is required for the proprietary JSON. Option B is unlikely to handle authenticated REST APIs and timestamp-based fetching. Option C is manual and not continuous. Option D introduces unnecessary AWS components. Option E implies the application can directly push, and doesn't address the timestamp-based pulling or proprietary format without pre-processing.
