Cyberthreats and security concerns are constantly evolving. From phishing emails and ransomware attacks, to network breaches and backdoor attacks, the list is long. For businesses, it is important to have a more proactive approach to cybersecurity, so that existing vulnerabilities can be fixed and future breaches can be thwarted. In this post, we are discussing on backdoor attack, also called backdoor exploit.
What is a backdoor?
An intentional backdoor allows a user (typically the admin) to gain access to a system, without following the existing authentication procedures. However, a backdoor may also refer to a malicious one, which gives access to a hacker, who then continues to access the system remotely. The backdoor can be used in many ways – for setting commands remotely, to add more malware, and often to just hack data. A lot of backdoor happens because of trojan files.
Preventing backdoor attacks
It’s important to understand that backdoor attacks mostly happen through malware files and downloads. For instance, an unsuspecting employee may download and install a file from an email. This file could be a trojan that can come off as legit software, and when the user tries to run the file, a backdoor is created for the hacker. Here are some basic things that companies can do to prevent backdoor attacks –
- Use an antimalware suite. There are some brilliant antimalware and antivirus suites available, which have been designed for business needs. Consider getting every networked device behind a firewall and install an antimalware.
- Network monitoring is a must. It is extremely important for businesses to have a network monitoring tool, which can help in identifying any activity that is not related to normal routines. Penetration testing can be handy for finding existing backdoors, if any.
- Educate employees. Some action must be initiated for a malware file to install a backdoor. In other words, employees are on the frontline of ensuring cybersecurity and preventing threats, and they must know the risks and consequences of their action. Consider spending on security training of employees on a regular basis.
The biggest concern with backdoors is detection. Backdoors are not easily detected, and by the time action is taken, considerable damage is done. In short, businesses need to focus more on how to prevent backdoor attacks in the first place. At the same time, there should be an incident response plan that states how such backdoor attacks will be managed.
