Data exfiltration attacks like Magecart have targeted a low-hanging fruit in the industry and have allowed attackers to steal millions of user’s credit card data. Existing security systems fail to prevent or even detect these attacks and this is a major blind-spot in the security monitoring systems. Content Security Policy is a standard supported in most modern browsers and can be harnessed to help increase protection against Magecart type attacks. This talk will explain how engineers in charge of infrastructure and servers can put this security measure in place and manage it effectively.
