Rootkit and Backdoor
Captions available
The idea
A rootkit modifies the operating system itself to hide its own existence; a backdoor is a concealed feature or command permitting actions normally denied.
In practice
One tampers with the station's own inspectors; the other is a door the blueprints never showed.
Where people slip
Both defeat inspection — one by blinding it, one by bypassing it.
