Fuzzing is a type of software testing in which an input is tweaked to test its behavior in an application. It is commonly used by attackers to uncover potential areas of weakness in an application in order to exploit the software. It typically involves submitting random values to application interfaces to examine application responses.

To better understand and protect against cyber attacks, it is important to take the following steps:

1. Ensure your devices are running the most up-to-date version of software and security patches.
2. Conduct regular, rigorous audits of all IT systems for vulnerabilities and potential areas of weakness.
3. Keep all software and anti-virus definitions updated regularly.
4. Implement measures to monitor network traffic, to detect suspicious activity and potential threats.
5. Ensure all software is scanned for malicious code prior to implementation.
6. Train users to use best practices when using the internet and handling company information.
7. Implement a cyber security policy and ensure everybody adheres to it.
