Responsibility for the Harm and Risk of Software Security Flaws

Software vulnerabilities are a vexing problem for the state of information assurance and security. Who is responsible for the risk and harm of software security is controversial. Deliberation of the responsibility for harm and risk due to software security flaws requires considering how incentives (and disincentives) and network effects shape the practices of vendors and adopters, and the consequent effects on the state of software security. This chapter looks at these factors in more detail in the context of private markets and public welfare.
