Discover the definition of the term Backdoor (Unhinged Door) presented by Les Assises de la Cybersécurité.


Discreet access placed illicitly in a system or software, making it possible to bypass legitimate access control. A backdoor is used in particular by attackers to ensure that they can return to their victim at will. Some have also been discovered in commercial software, placed at the design stage for ease of maintenance ('official' backdoor), or by a malicious employee.

A backdoor is never a feature, contrary to what we are sometimes led to believe!
