Businesses today are more at risk than ever before when it comes to network security vulnerabilities.
Thanks to the rise of the remote work culture, malicious actors now have a greater number of potential targets to choose from. And with 68% of business leaders saying their cyber risks are increasing, making sure your sensitive data is protected has never been more important
In this blog post, we will list and describe in great detail all of the major types of network security vulnerabilities that businesses face. We will also explain how businesses can avoid or prevent these threats from causing damage to their networks.
Before delving into the specific types of network security vulnerabilities, it’s important to understand what these terms mean. A cyber threat is any potential risk that can cause harm to a computer network and the sensitive data it holds.
An information security vulnerability, on the other hand, is a weakness in a network’s system or infrastructure that could potentially be exploited by a cyber threat. In other words, a cyber security vulnerability is the entry point for many types of attacks in network security.
Here we will discuss the most dangerous and most common network vulnerabilities and types of vulnerabilities in network security that all businesses face today.
This catch-all term refers to any type of malicious software that can harm a computer network. Some common types of malware include viruses, ransomware, and spyware.

To avoid falling victim to this particular cyber vulnerability, it’s crucial to have strong anti-malware software in place and regularly update your operating system and applications. It’s also important to educate employees on the risks of clicking on suspicious emails or links, as well as proper internet browsing habits.
Phishing is a form of social engineering and an attempt by cyber criminals to steal data such as usernames, passwords, and credit card details through fraudulent communication methods such as emails or text messages. These communications often appear legitimate, making them particularly dangerous to a business’ network security.
To prevent falling victim to this major security risk, it’s important to educate employees on identifying and reporting suspicious emails or messages. It’s also important for businesses to use multi-factor authentication for sensitive accounts and regularly update passwords to prevent hackers from gaining unauthorized access.
A Distributed Denial of Service (DDoS) attack occurs when cyber criminals flood a network with large amounts of traffic, preventing legitimate users from accessing the network or its services. These cyber attacks can have major repercussions for businesses, including loss of data and revenue.
Preventing DDoS attacks can be difficult, as they often originate from multiple sources at once. However, having a strong firewall in place, monitoring network activity and conducting vulnerability scans can help identify and prevent these attacks.
It’s also important to have a plan in place for how to quickly respond to a DDoS attack if one occurs.
In a man-in-the-middle attack, cyber criminals intercept and manipulate communications between two parties, potentially gaining access to sensitive information such as usernames, passwords, and financial details.
To avoid falling victim to this type of attack, it’s important to use encrypted communication security controls such as virtual private networks (VPNs) and secure websites with HTTPS. Ensuring that all Wi-Fi networks are secure is also crucial in preventing man-in-the-middle attacks.
In a SQL injection attack, cyber criminals gain access to sensitive information by inserting malicious code into a website’s input fields. This allows them to manipulate and exploit the underlying database.
To prevent this type of attack, businesses should regularly update their websites and use parameterized queries to ensure input fields cannot be manipulated by malicious code. It’s also important for businesses to properly secure their databases, perform penetration testing and regularly monitor for suspicious activity.
One of the simplest yet most common network security vulnerabilities is weak or reused passwords. These can easily be guessed or cracked by cyber criminals, allowing them access to sensitive information on a network.
To prevent weak password attacks, it’s crucial for businesses to enforce strong password policies and regularly update passwords. It’s also important to educate employees on the importance of creating unique, difficult-to-guess passwords, as they are very much the first line of defense against this particular cyber vulnerability.
Outdated software can contain network vulnerabilities that can easily be exploited by cyber criminals. This includes both operating systems and applications, making it crucial for businesses to regularly update all software on their network.
To avoid falling victim to an attack through unpatched software, it’s important to set up automatic updates where possible and regularly check for updates on all software used on the network. It’s also important to properly secure any internet-connected devices, as they may also contain unpatched software vulnerabilities.
Insider threats involve employees or individuals with authorized access to a network using that access for malicious purposes. This can include theft of sensitive information or sabotage of the network.
To prevent insider threats, it’s important for businesses to properly vet and monitor employees with access to sensitive information and networks. It’s also crucial for businesses to have a plan in place for how to quickly respond if an insider threat does occur.
Unsecured WiFi networks can easily be accessed by cyber criminals, allowing them access to a network and the sensitive information it contains.

Privilege escalation involves cyber criminals penetrating the network through a configuration error or software bug and expanding their reach. Gaining access to adjacent systems is known as horizontal escalation; while gaining a higher level of privileges is known as vertical escalation.
It allows the cyber criminal to perform unauthorized actions on systems, potentially allowing them to install malware, steal and erase data, and even lock out legitimate users.
Preventing privilege escalation attacks can be done by having experienced IT professionals administer network privileges, patch applications and OSes, and by conducting regular audits of user privileges.
In conclusion, there are a variety of network security vulnerabilities that businesses must be aware of and take steps to prevent and protect against. By staying informed and implementing the necessary security measures, businesses can minimize the risk of a potential attack and its resulting damage.
