Apache Struts, RCE and Managing App Risk

People used to argue about whether cyber security is a business problem or a technical problem. But this frames the issue poorly. “Problem” and “solution” imply that there is a definitive “solve.” Cybercrime isn’t a technical problem that can be definitively solved. It is an inherent business ris...
