Every networked device works like a computer. This simply means that hackers may look for security vulnerabilities in every device, right from IP cameras to computers and servers. Often using malware, hackers gain unauthorized access to systems and devices, causing breach, data theft and other kinds of damage. That’s backdoor exploit in short. Backdoor attacks are often hard to detect, because such attacks are often disguised. For instance, an employee may be tricked into giving access to an account through malware installed via a suspicious attachment. This is the simplest way in which a backdoor attack occurs, and it is important to step up and take preventive measures against the same. 

More on backdoor attacks

Not all backdoor attacks are malicious. Malware attacks are common for sure, but backdoor attacks can occur in various ways. It is important for companies to evaluate, understand and figure out threats and security flaws, for which constant testing is necessary. Scans are required to detect malware, and antivirus, antispyware, and antimalware software programs must be installed. Many companies are also hiring ethical hackers to find issues within the security perimeters that may not seem obvious otherwise. 

What can be done to prevent malware infection?

Since malware is often used as a means to cause backdoor exploit, prevention is necessary. Here are some of the basic steps that your business can take – 

1. Change all default details, usernames and passwords right after product is deployed. This includes your IP video surveillance systems, as well. 
2. Ensure that passwords are strong. Long passwords with at least 10 to 12 characters, special characters, uppercase and lowercase letters, must be encouraged. 
3. Use the lockout feature, so that brute force attacks are avoided. Also, where required, consider using multifactor authentication. 
4. Review your business’s security policies. Are you doing enough to test and scan networks and devices? Sometimes, an update might be necessary. 
5. Keep all software, firmware, and operating systems up to date. Ensure that the latest update is installed immediately. Also, if you don’t need a software or application anymore, uninstall the same. 

Lastly, be proactive and ensure that you are aware of the common means used by hackers to launch backdoor attacks. It is possible to thaw attempts, because all it takes is an eye for detail, especially for emails, links, attachments, and websites. Train your people, so that they know when and how to report a possible incident, and if required, invest in a tool that helps in controlling access rights!
