Network threats can come in many forms, but they all have one thing in common: the intent to breach your network and obtain access to data. Network security is essential because any attack on your network can be detrimental. In the contemporary world, a business that does not want to face a loss needs to understand how to identify network security threats & vulnerabilities.  

Companies, especially small businesses, need to understand cybersecurity threats. According to Business Insider, 28% of data breaches occur in small businesses as these are the most vulnerable ones. In addition to that, around 60% of businesses become bankrupt six months after undergoing a significant cyberattack or data breach.  

How exactly do threats and vulnerabilities differ?

Vulnerabilities are the places where you need to look for when hackers get through. They’re like weak spots in your systems, and they generally exist because someone overlooked a particular part of the network security area. Threats are things constantly wanting to disrupt your network security and your business.   

How to identify the network security threats & vulnerabilities?

As the world continuously moves into a more digital space, threats are also evolving at a relatively rapid pace. 

  1. Analyzing your own network:
    To make sure you can identify any potential threats and vulnerabilities your network must be transparent. You should be able to look at the way an attacker would see them with an understanding of their weaknesses in order to improve them! 
  2. Use threat intelligence:
    Another key way to identify potential threats and vulnerabilities is to take advantage of threat intelligence. The aim is to protect businesses from threats before they actually occur
  3. Constantly monitor your network:
    You can look for signs of potential threats and vulnerabilities by constantly monitoring your network. This can include things like unusual activity or unexpected changes in traffic patterns. 
  4. Keep your software up to date:
    One of the best ways to protect against threats and vulnerabilities is to make sure your software is always up to date. You can also opt for third-party software to take care of all your network security needs. NordLayer allows you to improve your security architecture to help protect your businesses against advanced threats or malware.

Identification of the most common security threats: 

It is essential to discuss the most common network security threats to help better identify the network security threats and vulnerabilities. The following are some security threats:  

Denial of Service (DoS) Attacks

A Denial of Service attack is an attempt to make a computer or network resource unavailable to its intended users. There are many forms of DoS attacks, but the most common involves flooding the target with requests for service until it can no longer respond to legitimate requests or crashing the system by overwhelming it with malformed or malicious data. so that it becomes impossible for anyone outside of this group to engage with any server or application running within their company’s perimeter. 


A virus is a piece of code that has the ability to replicate itself and spread. Viruses are a type of malware that can replicate itself and spread from one computer to another. Once a virus has infected a computer, it can use the network connection to spread itself to other computers on the network. This can pose a serious threat to network security, as a viral outbreak can quickly overwhelm network resources. In addition, viruses can be used to launch attacks on network systems, such as denial-of-service attacks. 

Advanced Persistent Threats (APTs)

An APT is a type of cyberattack where an intruder gains access to a network and remains there undetected for an extended period of time. The goal of an APT is usually to steal data rather than cause damage to the system.

SQL Injection Attacks

SQL injection attacks are a type of attack that allows attackers to execute malicious SQL code on a database. This can be done by inserting malicious code into an input field that is used in an SQL query. If the input field is not properly sanitized, the attacker’s code will be executed along with the rest of the query, potentially allowing them to access sensitive data or even take control of the database.


Phishing is the fraudulent process of attempting to acquire sensitive information such as usernames, passwords, and credit card details by disguising oneself as a trustworthy entity in an electronic communication. Phishers typically create fake websites or send fraudulent emails that look identical to legitimate sites or messages to trick victims into entering their personal information. Once they have this information, they can use it to commit identity theft or fraud.

As we’ve seen, there are many different ways that anyone can compromise your network security. However, by understanding the threats and taking steps to protect yourself, you can rest assured that your data is safe. Implementing a layered security approach will help keep your system secure from all angles and help your business prosper.
