send, recv, write) or middleware interception. Identify mismatched file hashes when compared at origin vs. destination. Watch for anomalous activity from processes interacting with secure transmission services (e.g., OpenSSL, scp).</p>- Detects

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 source | Channel | Data component |
|---|---|---|
| auditd:SYSCALL | send, recv, write: Abnormal interception or alteration of transmitted data | DC0021 OS API Execution |
| linux:syslog | Integrity mismatch warnings or malformed packets detected | 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.
| Field | Description |
|---|---|
WatchedProcesses | List of processes authorized to handle transmitted data (e.g., sshd, nginx). |
HashCheckInterval | Frequency of out-of-band integrity verification checks. |
