A **Qubes canary** is a security announcement periodically issued by the [Qubes
|
|
security team](/security/#qubes-security-team) through the [Qubes security
|
|
pack](/security/pack/) consisting of several statements to the effect that the
|
|
signers of the canary have not been compromised. The idea is that, as long as
|
|
signed canaries including such statements continue to be published, all is
|
|
well. However, if the canaries should suddenly cease, if one or more signers
|
|
begin declining to sign them, or if the included statements change
|
|
significantly without plausible explanation, then this may indicate that
|
|
something has gone wrong.
|
|
|
|
The name originates from the practice in which miners would bring caged
|
|
canaries into coal mines. If the level of methane gas in the mine reached a
|
|
dangerous level, the canary would die, indicating to miners that they should
|
|
evacuate. See [Wikipedia: warrant
|
|
canary](https://en.wikipedia.org/wiki/Warrant_canary) for more information, but
|
|
bear in mind that Qubes Canaries are not strictly limited to legal warrants.
