To answer the question, let’s analyze the options provided:

1. Backdoor: This is a method that allows users to bypass normal authentication processes to gain unauthorized access to a computer or system.

2. Trojan: This refers to malware that disguises itself as legitimate software to trick users into installing it, enabling unauthorized access indirectly.

3. Ransomware: This is a type of malware that encrypts files on a victim's device, demanding a ransom for their decryption. While it can lead to unauthorized access, its primary function is not to provide access but to extort.

4. Rootkit: This is a collection of software tools that enable unauthorized users to gain control of a computer system without being detected. Rootkits facilitate unauthorized access but are generally used once the access has already been gained.

A backdoor is a means to get unauthenticated access to a computer or device.
