Backdoor vs. Rootkit — What's the Difference?
By Maham Liaqat & Urooj Arif — Updated on May 9, 2024
A backdoor is a secret method of bypassing normal authentication to access a system, while a rootkit is a malicious software suite that hides its presence and can control system functions to maintain unauthorized access.

Key Differences
A backdoor is a means to access a system without using standard authentication methods. It can be placed deliberately for maintenance or introduced maliciously. On the other hand, a rootkit is a software package designed to hide malware presence and provide unauthorized access.
Backdoors are sometimes included by developers for troubleshooting, but they are exploited by hackers for illicit control. Rootkits, meanwhile, are specifically designed to grant stealthy administrative privileges to attackers by manipulating system files.
Backdoors offer external access by circumventing regular security protocols, which can expose the system to further threats. In contrast, rootkits operate internally, masking their activities and those of other malware to avoid detection.
While backdoors allow attackers direct entry into the system, rootkits aim to remain undetected, altering system behaviors and concealing logs. Both pose significant security risks due to the control they give to malicious users.
Backdoors might be removed if discovered and patched in security updates. However, rootkits often require a complete system reinstallation to eradicate them fully due to their deep integration.

Rootkit
A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or an area of its software that is not otherwise allowed (for example, to an unauthorized user) and often masks its existence or the existence of other software. The term rootkit is a compound of "root" (the traditional name of the privileged account on Unix-like operating systems) and the word "kit" (which refers to the software components that implement the tool).
