BLOCKBACKDOOR

Abstract

A backdoor is an undocumented method of gaining access to a program or a computer by using another installed program that bypasses normal authentication. This paper deals specifically with hardware backdoors. These backdoors reside in the hardware components of a computer device and they are often very hard to detect using normal intrusion detection methods. Our research on the topic revealed that most hardware computer devices are either manufactured with backdoors within their circuits intentionally by the manufacturer or some vulnerability exists without the knowledge of the manufacturer. As hardware backdoors remain the most dangerous and undetected method used by information system intruders, it is as good as nothing if remote connections cannot be established to them. This paper will showcase how these backdoors work together on different devices in a 4 network system and the various methods that can be employment to curb the problem. This will ensure that whatever the number of backdoors residing in a device, they will be inaccessible to the intruder and remain harmless to the computer system or device. As Kenya anticipates digitalizing most of its systems for the realization of the Vision 2030, digital gadgets will be the order of the day and suppose they pose the risk of information security breach then a big problem lies ahead. The rapid embracement of digital devices, example vehicle speed governors, will most likely create an information security breach in communication systems since these devices could be potential targets.
