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 | execve | DC0032 Process Creation |
| NSM:Connections | sshd or PAM logins | DC0002 User Account Authentication |
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 |
|---|---|
UserContext | Identify logins to root or sudoers not aligned with normal usage profiles. |
HostDensityThreshold | Number of unique systems a user authenticates to in a time window. |
LoginMethod | Trigger on rarely used access methods such as password instead of SSH key. |
