Backdoor- A breach in security

144
Backdoor is a means of access to a computer program that bypasses security mechanisms. A programmer may sometimes install a backdoor so that the program can be accessed for troubleshooting or other purposes. However, back doors are often used by attackers who detect and/or install it themselves. Whether installed as an administrative tool or a means of attack; a back door poses as a security risk aiding crackers looking for vulnerable systems.
Once the backdoor has been established by cyber criminals, they gain system entry giving them complete access to all kind of sensitive information of the victim such as his financial details, account numbers,passwords etc. Such access enables the criminal to maliciously vandalize, alter,move, or delete files from the infected computer.

ILLUSTRATION:
In October 2006, iPods that were released by Apple had a malware embedded in them. All Apple devices are run by users
on Windows systems. For this reason, even Apple checks its product’s functioning on Windows computers. One of those computers was infected.When ever your computer asks you to run a file called RavMonE.exe. Such an infection is possibly sent from the backdoor of an infected computer.
PROTECTION TIPS:
•Always check for loopholes in your system. A backdoor cannot be detected by normal antivirus softwares.
• If you feel your computer is not behaving normally and seems infected or that few files are missing ,immediately take it to a computer expert for him to check if the system is compromised.
