Given the current technologies that we have at our disposal, we should assess the continued use of signatures as a means of authenticating card transactions. It is important to layer security tools and procedures. Methods to devalue payment data, like tokenization and encryption for data at rest, in use, and in transit, mitigate the effect of a data breach.
Analytics can identify and prevent fraudulent transactions. Firewalls and segmentation of technology supporting critical functions can protect networks from outside attacks. Also, remember that people inside your organization and organizations that you work with can pose a significant risk. One study found that more than 20 percent of security incidents could be attributed to insiders.
