How does Splunk ES handle data normalization?

Splunk Enterprise Security handles data normalization by aggregating different sources into a consistent format. This process is crucial because organizations typically collect security data from a variety of sources, such as firewalls, intrusions detection systems, and application logs. Each of these data sources can have its own format, which might make it challenging to analyze the data collectively for security insights.

Normalization ensures that disparate data types can be treated uniformly, enabling more effective searches, reports, and alerts. By converting data into a standard schema, Splunk ES allows users to correlate data effectively across different data sources, facilitating better detection of security threats and anomalies.

The other options do not accurately describe the normalization process. Filtering out irrelevant data addresses data quality and relevancy but doesn't focus on the standardization of formats. Storing data in a cloud environment relates to where the data is kept rather than how it is formatted and processed. Encrypting sensitive information is a security measure to protect data integrity and confidentiality, but it does not involve the normalization of data.
