A backdoor is an unseen point of entry that bypasses any system security measures. Backdoors enable hackers to enter the system without being authorized.
Backdoor access may take the form of a hidden piece of a program, a different program, code in the firmware of the equipment, or parts of a operating system, for example Windows.
Trojan horses as well can be utilized to create vulnerabilities in a device. A Trojan horse may seem, by all accounts, to be a benign program, yet when executed, it triggers an action that may introduce unwanted indirect access. These sorts of indirect accesses have real uses, for example, furnishing a hacker with the capability to reset users’ passwords.
Many systems that store data inside the cloud are not secure. When many enterprise applications are offered on cloud, hackers may be able to access all of them through the most vulnerable application. Default passwords can work as backdoors when these are not changed by the user. Some benign troubleshooting efforts can likewise create backdoor accesses in the event that they are not abandoned, deleted or uninstalled following their use.
Example:
“When a backdoor was discovered in the company’s software, a full investigation was launched and thousands of customers promptly received a patch to fix the issue.”
