<p>Detection of Linux container escape attempts via syscalls (unshare, keyctl, mount) or process execution outside container namespaces. Defenders may correlate unusual system calls from containerized processes with subsequent process creation on the host or modification of host resources.</p>

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
SyscallWhitelistExpected syscalls by containerized workloads. Deviations may signal an escape attempt.
TimeWindowDefines correlation window (e.g., 60s) between suspicious syscalls and follow-on host process activity.
