Web server is a web application carrier, so if the carrier has security problems, the security cannot be guaranteed in running web applications. Therefore, the security of the web server cannot be ignored.

This chapter will talk about runtime security problems common in a web server. The list of problems discussed here is not exhaustive. These are problems that have been encountered frequently in recent years.
