Backdoors can be very difficult to detect, and detection methods vary considerably depending on the computer’s operating system. In some cases, anti-malware software may be capable of detecting backdoor software. In other cases, security professionals may need to use specialized tools to detect backdoors. There are several different strategies for avoiding backdoor attacks. First and foremost, organizations need to adhere to security best practices, such as avoiding untrusted software and ensuring that every device is protected by a firewall. Application firewalls can also help to prevent backdoor attacks, since they restrict the traffic that can flow across open ports. It is also important to monitor network traffic for signatures that may indicate the presence of a backdoor.
