DET0304 Detection Strategy for Endpoint DoS via Application or System Exploitation

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.

Log sourceChannelData component
auditd:SYSCALLProcess segfault or abnormal termination after invoking vulnerable syscall sequenceDC0033 Process Termination
journald:ApplicationSegfault or crash log entry associated with specific application binaryDC0038 Application Log Content
NSM:FlowUnusual request pattern leading up to service crash (e.g., malformed or oversized payload)DC0085 Network Traffic Content

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
CrashPatternSpecific binary fault signature or stack trace identifiers unique to the application context
ExploitSourceIPSuspect source IPs for correlation across requests and service failure timing
