Backdoor (computing) | Webviktaya Cyber Security & Website Malware Removal
A backdoor is a method, often secret, to bypass authentication or normal encryption in a computer system, a product or an integrated device (for example, a home router), or its realization, for example. as part of a cryptographic system, an algorithm, a chip set or a “homunculus computer”: a small computer inside a computer (such as the one found in Intel AMT technology). Backdoors are often used to secure remote access to a computer, or by accessing plain text in cryptographic systems. The backdoor can be used to access passwords, delete data on hard drives or transfer information within the cloud.
A backdoor can take the form of a hidden part of a program,a separate program (for example, Back Orifice can subvert the system through a rootkit), code in the hardware firmware or parts of an operating system like Windows Trojan horses can be used to create vulnerabilities in a device. A Trojan horse may seem like a totally legitimate program, but when it runs, it activates an activity that can install a backdoor. Although some are installed in secret, other back doors are deliberate and widely known. These types of backdoors have “legitimate” uses, such as providing the manufacturer with a way to restore user passwords.
Many systems that store information within the cloud fail to create accurate security measures. If many systems are connected within the cloud, hackers can gain access to all other platforms through the most vulnerable system.
