A vulnerability in cyber security is a weakness in a system that can be exploited by cyber attackers to gain unauthorised access to or perform unauthorised actions on a computer system. These vulnerabilities can exist in a variety of forms, from software bugs to human error, and each type requires a specific approach for mitigation. Here, we take a look at the most common types of vulnerabilities that threaten an organisation’s cyber security today.


Software Vulnerabilities

Software vulnerabilities are perhaps the most well-known and widely discussed type of security vulnerability. They occur when there are coding errors or flaws within the software. Addressing these vulnerabilities often involves regular software updates and patches from the developers.

Outdated or Unpatched Software

Software that is not regularly updated or patched presents significant vulnerabilities. Attackers exploit these weaknesses to launch malware, ransomware, and other cyber attacks. Implementing a rigorous process for prioritizing and automating software updates and patches can mitigate this risk​​​​.

Zero-day Vulnerabilities

Zero-day vulnerabilities are previously unknown flaws that are exploited before developers have a chance to address them. These vulnerabilities require a proactive defense strategy, including advanced threat detection systems and a comprehensive endpoint security solution​​​​.


Hardware Vulnerabilities

Hardware vulnerabilities arise from physical or design flaws in hardware components. Mitigating hardware vulnerabilities can be challenging and may require physical modifications or firmware updates. Default usernames and passwords, Outdated firmware and Unsupported legacy devices are just some examples of hardware vulnerabilities.

Network Vulnerabilities

Network vulnerabilities exist in the infrastructure and protocols that govern internet and network communications. Weaknesses in network architecture, such as unsecured Wi-Fi networks or outdated encryption protocols, can allow attackers to intercept or alter data in transit. Effective network security measures, including the use of VPNs and updated encryption methods, are vital for protection against these vulnerabilities.


Human Vulnerabilities

Often overlooked, human vulnerabilities refer to the ways in which human error or behavior can lead to security breaches. Phishing attacks, where victims are tricked into revealing sensitive information, and password vulnerabilities, stemming from the use of weak or reused passwords, fall into this category. Educating users on safe online practices is a key step in mitigating human vulnerabilities.


Misconfigurations occur when security settings are not correctly implemented, leaving systems exposed. Automated configuration and regular updates to security settings can help minimize these risks. Ensuring that IT teams are well-versed in best practices for cloud and application security is vital for preventing misconfigurations​​​​.

Unsecured APIs

Application Programming Interfaces (APIs) serve as bridges between different software applications, facilitating their interaction. Unsecured APIs are a prime target for attackers due to their accessibility over the internet and inherent security risks. Securing these requires encryption, proper IT hygiene during development, and regular key rotation​​​​.

Weak or Stolen User Credentials

Weak passwords and reused credentials offer easy access for attackers. Organizations should enforce strong, unique password policies and implement multi-factor authentication (MFA) to enhance security​​​​.

Access Control and Unauthorised Access

Excessive access rights increase the risk of data breaches. Adopting the principle of least privilege (POLP) ensures that users have only the access necessary for their job functions, reducing the attack surface​​​​.

Addressing Cyber Security Vulnerabilities

Effective vulnerability management is crucial for mitigating the risks posed by these vulnerabilities. This involves a combination of technical measures, such as vulnerability scanning and access control, and organizational strategies, including training and awareness programs.
