What can cause latency issues in Azure Sentinel when processing security logs?

The selection of inconsistent data ingestion from sources as the correct answer highlights a crucial factor that can indeed lead to latency issues in Azure Sentinel. When data sources do not consistently transmit logs or security events, it can create bottlenecks in the processing pipeline. Azure Sentinel relies on this data to perform analytics, generate alerts, and provide insights into security incidents.

If data ingestion is erratic, it can result in delayed processing of logs, causing a slowdown in how quickly analysts can access the information needed to address security concerns. This inconsistency could stem from various factors, such as connectivity issues, misconfigured data connectors, or changes in the source systems that affect how logs are sent.

In contrast, excessive customization of analytics rules primarily affects the complexity and performance of rule evaluation rather than the ingestion process itself. Insufficient network bandwidth can certainly cause some performance drawbacks, but it is typically more significant during high-volume data transfer rather than affecting latency in a structured logging environment like Azure Sentinel. The complexity of the security architecture may introduce challenges in managing systems and workflows, but it does not directly correlate with data ingestion latency in the way that inconsistent data ingestion does.
