Security breach

What is a security breach?

It is the unauthorized access of information on networks, servers, or devices, getting around security on those systems, ultimately resulting in data leakage.

Security breaches are usually used within the context of companies, organizations, or governmental institutions where security defenses were bypassed in order to access confidential information such as identities, email addresses, passwords, sensitive financial information, etc.

Known cases

Some of the most high-profile cases of data leakage include EBay, JP Morgan Chase, the US voter registration database, US diplomatic cables, the NSA prism program, and the Panama Papers.
