DET0376 Behavioral Detection Strategy for Network Service Discovery Across Platforms

Log sources and channels

Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.

Mutable elements

Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.

FieldDescription
MDNSServiceQueryPatternsmDNS queries such as _ssh._tcp.local that may indicate service discovery.
UserContextAdjust alerting based on whether discovery activity originates from a background daemon vs. interactive session.
ScanToolListExpected tools that could trigger mDNS or TCP/UDP scans (e.g., dns-sd, nmap).
