Answer 1

Answer :

Backdoor is a means to gain access to a system by bypassing the device’s customary security mechanisms.

According to Wikipedia, 'A backdoor is a method, often secret, of bypassing normal authentication or encryption in a computer system, a product, or an embedded device (e.g. a home router), or its embodiment, e.g. as part of a cryptosystem, an algorithm, a chipset, or a "homunculus computer" —a tiny computer-within-a-computer (such as that as found in Intel's AMT technology). Backdoors are often used for securing remote access to a computer, or obtaining access to plaintext in cryptographic systems.'
