Measuring Attack Surfaces of Open Source IMAP Servers

Abstract: "The attack surface metric provides a means of discussing the susceptibility of software to as-yet-unknown attacks. A system's attack surface encompasses the methods the system makes available to an attacker, and the system resources which can be used to further an attack. The attack surface metric can be used to compare the security of multiple systems which provide the same function. The Internet Message Access Protocol (IMAP) is a protocol which has been in existence for over a decade. Relative to web (HTTP) and e-mail transfer (SMTP) servers, IMAP servers are a niche product, but they are widely deployed nonetheless. There are three popular Open Source Unix IMAP servers (UW-IMAP, Cyrus, and Courier-IMAP), and there has not been a formal security comparison between them. In this project, I use the attack surface metric to discuss the relative security risks posed by these three products. I undertake this evaluation in service of two complementary goals: to provide an honest examination of the security postures and risks of the three servers, and to advance the study of attack surfaces by performing an automated attack surface measurement using a methodology based on counting entry and exit points in the code."
