T1565.001 Stored Data Manipulation
Part of
DET0193 Detection Strategy for Stored Data Manipulation across OS 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
FileIntegrityBaselineBaseline hash values or metadata for stored data files to detect manipulation.
AllowedEditorsWhitelisted applications permitted to update stored data (e.g., Outlook, MySQL).
