Computer Backdoor and Security Threats! A back door is a means of access to a computer program that bypasses security mechanisms.
Backdoors are lines of code developers intentionally install in firmware so that manufacturers can safely upgrade our devices and operating systems. A programmer may occasionally install a back door so that the program can be accessed for troubleshooting or other purposes. However, attackers often use back doors that they detect or install themselves, as part of an exploit. In some cases, a worm is intended to take advantage of a back door created by an earlier attack. For example, Nimda gained entrance through a back door left by Code Red.
The challenge is that backdoors can also be used surreptitiously to harness everything from our webcams to our personal data, whether installed as an administrative tool or a means of attack, a back door is a security threat, because there are always crackers out there looking for any vulnerability to exploit.
Some government officials will be advocating for a set of “golden keys,” which would allow law enforcement to use backdoors as they wish. This won’t just affect the usual suspects, such as Facebook and Google.Opponents argue that the simple act of creating a backdoor would leave ordinary people vulnerable to everyday attacks by even unskilled hackers.
