Breach

A breach is the actual usage of a vulnerability to gain unwanted access to resources on a server.

A breach may:

• Steal sensitive information, such as, and not limited to, user credentials, financial data, source code

• Deface the website

• Install backdoors or malware

• Use of the server for further attacks, e.g., DDoS, phishing, crypto-mining

After a breach, there is a phase of remediation.
