Backdoor attack is a type of security breach, where hackers gain access to systems, networks, and/or devices, by bypassing the existing authentication methods. Most backdoors are created when a user installs a malicious file, typically a trojan that disguises itself as a valid product download of software. Backdoors, however, are not always malicious. Many businesses create these backdoors for their testing and cybersecurity teams, to gain access to get work done. Backdoor attacks can have serious consequences – from data breach to having cameras hacked, businesses have a lot at stake. In this post, we are sharing more on how to address backdoor attack concerns.
Follow the basics
The biggest problem of backdoor attacks is late detection. In many cases, attacks are discovered only after months or weeks, and by then, hackers have probably got everything they needed. Some of the basic steps go a long way in preventing such attacks, such as –
- Placing devices behind firewalls. All devices that are connected to a network should have a firewall installed. This works as the first barrier.
- Install antimalware and antivirus software. Like we mentioned, majority of backdoor attacks happen through malware files. There are some amazing antimalware and antivirus products in the market, which can find and remove malicious files. The user can get a warning when a malicious file is being run or downloaded.
- Make the most of multifactor authentication. Just a single password is not enough for cybersecurity anymore. With multifactor authentication, it is possible to add that extra layer of security, so that even if a hacker has the login credentials, they still cannot breach the other security measures.
- Focus on strong passwords. Backdoor attacks often involve brute force attacks, and to prevent that, strong passwords are a must with multifactor authentication. Ask your employees, users, and customers to use passphrases with special characters that are at least 16 characters long.
- Penetration testing is a must. To check if there is any suspicious network activity, regular penetration tests are a must. There are several ways in which networks and systems can be checked and monitored for backdoor attacks and unauthorized access.
The aftermath of a data breach could be detrimental for any business, and in most cases, backdoor attacks have serious consequences. Instead to waiting for a breach to happen, take the necessary preventive and proactive steps to enhance and take cybersecurity to the next level.
