Tackling angry emails from employees about Wi-Fi running slowly, or it taking a lifetime to download a simple setup file or load a business-critical application, can hamper productivity.

In this four-part series, we explore hypothetical cyberattacks inspired by real-life events in four different industries: healthcare, finance, manufacturing, and education. We’ll take a look at unforeseen security attack scenarios, and discover how user and entity behavior analytics (UEBA) can be leveraged to safeguard organizations. In this second post of the series, we’ll examine cyberattacks that threaten the financial sector.
