What is a vulnerability?

A vulnerability is a weakness that can be exploited by cybercriminals to gain unauthorized access to a computer system. After exploiting a vulnerability, a cyberattack can run malicious code, install software, and steal sensitive data.

Protecting your systems and applications from vulnerabilities protects both Queen’s and your personal data from the risk of cyberattack.
