Describe the Value of Data Normalization in Order to Support Integration into Cybersecurity Defense Programs, Such as Security Monitoring and Threat Hunting, E.g. with CIM, CEF. CYBERSECURITY-DEFENSE-ARCHITECT Practice Questions (Page 1)

   A security team is integrating a third-party intrusion prevention system (IPS) with an existing SIEM. The IPS vendor supports exporting events in Common Event Format (CEF). The SIEM can parse CEF natively. What is the main advantage of using CEF for this integration?

   • AIt automatically encrypts the event data during transmission, ensuring confidentiality.
   • BIt guarantees that the IPS will detect all known threats without additional tuning.
   • CIt eliminates the need for any field mapping because CEF uses the same field names as the SIEM's internal schema.
   • DIt provides a standardized, vendor-neutral format that the SIEM can parse and normalize more easily than a proprietary log format.

   What is a common benefit of implementing data normalization in a cybersecurity defense program?

   • AElimination of all false positives in security alerts
   • BAutomatic compliance with all regulatory requirements
   • CReduced complexity in security operations and improved detection capabilities

   What is the Common Event Format (CEF)?

   • AA type of encryption used for secure log transmission
   • BA standard format for exchanging security event information between systems
   • CA database schema for storing security logs
   • DA proprietary format used only by Splunk

   A Splunk architect is mapping a custom application's logs to the CIM. The application logs contain a field 'user_id' that is a numeric ID, and a separate field 'user_name' that is the human-readable username. The SOC wants to use the username in dashboards and alerts. How should the architect map these fields to CIM?

   • ADo not map either field because CIM does not support usernames.
   • BMap both 'user_id' and 'user_name' to the CIM 'user' field using a multivalue field.
   • CMap 'user_name' to the CIM 'user' field and keep 'user_id' as a separate custom field.
   • DMap 'user_id' to the CIM 'user' field and ignore 'user_name'.

   Why is data normalization essential for integrating diverse data sources into a cybersecurity defense program?

   • AIt guarantees that no data is ever lost during ingestion
   • BIt allows data from different sources to be analyzed and correlated consistently
   • CIt ensures all data sources use the same vendor
   • DIt eliminates the need for any data parsing
