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
AccessedFilePathMonitored paths such as /proc/[pid]/mem or /proc/[pid]/maps may need to be scoped based on environment
ProcessNameCommand-line or binary names associated with credential scraping tools may vary
UserContextElevated user or unexpected user context accessing other process memory may indicate malicious activity
TimeWindowCorrelating memory access with process creation or ptrace activity within a specific time range
