Types of vulnerabilities in network security that companies need to be aware of.

Information Technology (IT) is integrated into nearly every business process. Every computer your company uses creates more opportunities for cybercriminals. In some cases, the damage caused by cybercriminals could be unrecoverable and force your company to close. There is a lot of vulnerability in information technology — but you can mitigate cybersecurity threats by learning from security vulnerability examples, and being proactive in addressing common IT vulnerabilities.

There are 7 main types of network security vulnerabilities, which you can see in these examples:

1. System Updates

Updating your company’s computer software is one of the most effective ways of improving your cybersecurity. Using outdated software allows criminals to take advantage of IT vulnerabilities. Software developers routinely release security and software updates. Make sure that every computer is updated quickly when these packages become available.

2. Email

Email also poses a significant threat to security. Opening an email with malware or viruses could compromise your security system. Use your email system’s automated email scanners to quarantine junk mail. Also, train your staff to spot and delete emails that could be hazardous to your security systems.

3. Login Information

Unprotected account login information is one of the biggest threats to your company’s IT security. Having the right credentials lets anyone bypass your security systems entirely. Explain to staff members the importance of protecting login information from everyone, even each other. Also, be sure that your IT staff deletes old user credentials from the system and limits people’s ability to create new ones.

4. Flash Drives

Flash drives and similar devices create easy opportunities for someone to place malware and viruses directly into your computer systems. Flash drives can hold any type of file. Limit who can use flash drives and where they can use them so that your company can control these threats. Make sure that all of your company’s computers have scanning programs that examine these devices when they are connected.


Downloads are another effective way to bypass a security system to put malicious software on your company’s computers. Your IT team can install software that prevents downloads from most programs, including web browsers. This will limit who can download materials and where they can be downloaded from, which will lower your chances of encountering malware.

6. Internet Access

Most malware installations come from different places on the internet. Some malware programs can hide in web pages, and try to download themselves when you access the page. Get with your IT team and have them set up firewalls and other protection systems to prevent online malware from accessing your systems.

7. Bad User Practices

The biggest threat to your company’s cybersecurity is bad user practices. Even with all of these systems in place, they can fail if your staff doesn’t understand how to use them. For example, it is easy for staff members to forget to lock or log out of their computers when they leave their desks. This is a perfect opportunity for someone to access your computer systems without needing malware or other devices. Schedule periodic safety review meetings with your staff to educate them and reinforce good security habits in the workplace.

Cybersecurity is a growing concern for any company; recent events have proven that everyone’s cybersecurity should be taken seriously. Thankfully, you can easily reduce your company’s risk by following these tips.
