The 'Monitor DNS For Brand Abuse' rule is designed to detect potential abuse of branding through monitoring DNS queries for faux or lookalike domain names that mimic legitimate domains. This search leverages the Splunk data model for network resolution to aggregate DNS answer values and identify suspicious DNS requests from various sources. By utilizing a combination of DNS logging data and the output of the DNSTwist domain permutation search, this rule aims to proactively identify and mitigate risks associated with brand dilution and fraudulent domains that could mislead users or harm a brand's reputation. Although it has been marked as deprecated, the implementation of this rule requires a solid foundation of DNS log ingestion and an understanding of approved domain variations to facilitate accurate detection and corresponding investigation.
