Enhancements to Data Feeds Documentation
Improvements have been made to the documentation surrounding data feeds used for security analysis. These feeds include various sources, such as public NTP servers, and provide valuable context for investigating IP addresses beyond merely identifying malicious activity. The documentation now better explains the purpose of these data feeds, differentiating them from block lists, highlighting their usefulness in understanding network traffic associated with legitimate services. One newly introduced data feed focuses on repackaged open-source threat intelligence, which consolidates indicators of compromise gathered from various blogs and articles, enhancing the analysis capabilities for users.
