Arranging appropriate Computer Networking Certification Training Courses for professional teams can avoid such vulnerabilities. By taking a look at these security vulnerabilities, one can at least get an idea about how they can destroy our data. 

Stats and Facts:

Did you know?

  • In the year 2016, 95% of the breached records came from just three industries.

Top 5 Network Security Vulnerabilities Affecting Businesses:

Below you can find all the details about the top 5 network security vulnerabilities affecting businesses.

Phishing Attacks:

This is a type of attack where the hacker is pretending to be someone you know or trust. This can be your boss or anyone from your organization or business. The most common example that fits here is the hacker emailing you from a very familiar or slightly altered email address.

The hacker emails you a link and asks you to go to a particular website or follow the link. Then asks you to log into your account and enter your details. The moment you enter all your personal details, the hacker would get all the information in real-time. 

Studies have shown that this attack is responsible for 78% of all cybercrimes. 

Malware Attacks:

This is another kind of attack that can affect businesses to a great extent. This attack encloses in it multiple cyber threats like Trojans and other viruses. It is a varied term for malicious code that is created by the hacker to gain access to different networks thereby stealing or destroying data on computers. This can come from any source like spam emails or downloading something from a malicious website or connecting to an infected device or machine. This type of attack can give a third-party access to all your data.

Cloud Jacking:

This is a process in which cloud computing is infiltrated by a third party. As soon as a hacker manages to enter your company cloud, he can reconfigure the cloud code and manipulate all your sensitive data. He may even try to eavesdrop on employees and company communications and can also take control of the entire cloud. Similarly, cybercriminals will also use this opportunity to develop a variety of phishing schemes. This will be done by uploading fake memos or instructions etc and then forwarding them to all the employees. Now the employees will believe the instructions are from the company and would follow them which can harm the company.

Mobile Malware:

The use of working from mobile has increased a lot. Not just the employees use mobile for work but many professionals have also started to move from desktops to either laptops or smartphones. And this is the part where the chances of cybercrimes increase to a drastic extent. Mobile malware is specifically used on mobile devices for malicious purposes, a majority of the employees have started to access and store the company’s data on mobile devices.

Insider Threats:

Last on our list is Insider Threats which as posed by employees have affected 34% of the businesses around the world. The insider threats can happen by the employees intentionally or even accidentally out of ignorance. As more employees have started to work remotely, the chances of insider threats increase even more. And that is why organizations must take extra precautions to curb insider threats. 


Cyber threats are and have been real all this time and yet the majority of the organizations don’t pay attention to them unless it happens to them. The above top 5 network security vulnerabilities that can affect businesses are just the tip of the iceberg. There are many more network vulnerabilities that can put the Security Threats of the entire business at risk. So we urge all companies/businesses to wake up and pay attention to the harm that cyber threats have and can do to us and take necessary measures to prevent any attack in the future.
