The growth of technology has been a true boon to the world. Improved technology has allowed for increased efficiency, streamlined processes, and all kinds of new possibilities. In business, technology has allowed you to connect with people from all over the world at lightning-quick speeds.


Technology does come with its dark side. Security issues, particularly network security vulnerabilities, have become a growing concern for businesses and individuals alike. Learn more about common IT vulnerabilities in business below.




Malware is one of the most well-known vulnerabilities and for good reason. Malware is a broad category of malicious software designed specifically to cause some sort of damage to a network, device, server, or client. If you want to learn about how to avoid security breaches, it’s important to know the various types of malware. Types of malware include:


  • Viruses – Much like physical viruses, computer viruses are designed to replicate and spread to several computers and devices. Viruses can perform a wide range of functions, like stealing personal information or damaging software.
  • Spyware – Spyware is software that is designed to remotely spy on a user’s activities. They can be used to steal data or monitor activity.
  • Ransomware – This software essentially locks your system or specific documents until you pay a ransom.
  • Adware – A more common vulnerability in the earlier days of the internet, adware causes pop-up ads to automatically and constantly appear. This is usually bundled into spyware on seemingly innocuous free programs.
  • Cryptojacking – Relatively new with the advent of cryptocurrency, cryptojacking essentially loads cryptomining code onto your computer, forcing your computer to mine for cryptocurrency in the background. This is an extremely resource intensive process that can heavily slow down your computer and network and prevent you from properly engaging with your clients and customers.


Installing virus scanners and shields is a good way to address most malware issues. Email virus detection checks email attachment for any potential issues.


Weak Passwords


Just about everything you use needs a password, from your Wi-Fi network to your email account. With so many passwords in your life, it can be easy to get lazy with your passwords. Using weak or default passwords might feel simple in your day-to-day, but it leaves you, your computer, and your business open to the impacts of cyber attacks. Default passwords, “password”, or “abcd1234” are exceptionally easy for malware and hackers to crack.


Use complex passwords that combine letters (both lowercase and uppercase), numbers, and symbols, and consider changing your passwords regularly. Even better, invest in a password managing software to lower your cyber risk. 


Everyone should also use some form of two-factor or multi-factor authentication. This forces users to use multiple authentication methods to log into networks or programs, which makes it harder for hackers to attack accounts with just a username and password. 


Unpatched Software


As more hackers find unpatched vulnerabilities with software, developers are constantly patching and updating software to close loopholes and improve general efficiency. Firmware does the same thing but for hardware. It’s important to download and install these patches as soon as they are made available to prevent potential attacks and lower your security risk. Always keep your software current. Most programs have automatic updates enabled.


Poor Data Backup


While you don’t want an attack to happen, you still want to be prepared in the event it does happen. This is where good data backup practices will shine. Creating an offsite backup can save you time during the recovery process and provide peace of mind. Backups mean that your data is easy to restore, so you can get right back to work. Data backups come in all forms, from physical hard drives to cloud storage. Choose a strategy that works for your workflow and back your data up regularly.


Firewall Configurations


While it’s not without its own vulnerabilities, a firewall is the first line of defense for your network. It essentially monitors all of the packets that are going out and coming in. Based on the firewall’s settings and configurations, it determines what is “safe” and what isn’t. That means that a firewall can prevent unauthorized users or sources from using your network while preventing users on the network from accessing potential threats. Proper configuration ensures that your firewall will work as intended and make accessing any security threat much harder for anyone trying to gain unauthorised access to your system.


Mobile Device Problems


Even with all the latest software patches, complex passwords, and proper firewall setup, an unsecured mobile device can provide an easy entrance for cyberattacks. Bluetooth and unsecured Wi-Fi gives potential hackers easy access to passwords, emails, and other personal information. Avoid connecting to public Wi-Fi networks or downloading apps that come from less-than-savory sources.


Human Error


Human error is often the biggest security vulnerability. While there are certainly people who want to intentionally cause harm, most security issues caused by human error are purely accidental. This could be an employee accidentally clicking a link in an email, downloading an app, or giving login credentials to the wrong person.


Thankfully, applying most of the above strategies can help to reduce any harm that comes from human error. It can also help to train employees in cybersecurity and cybersecurity vulnerability.
