NDLI: Towards fully automatic placement of security sanitizers and declassifiers

Content Provider	ACM Digital Library

Abstract	A great deal of research on sanitizer placement, sanitizer correctness, checking path validity, and policy inference, has been done in the last five to ten years, involving type systems, static analysis and runtime monitoring and enforcement. However, in pretty much all work thus far, the burden of sanitizer placement has fallen on the developer. However, sanitizer placement in large-scale applications is difficult, and developers are likely to make errors, and thus create security vulnerabilities. This paper advocates a radically different approach: we aim to fully automate the placement of sanitizers by analyzing the ow of tainted data in the program. We argue that developers are better off leaving out sanitizers entirely instead of trying to place them. This paper proposes a fully automatic technique for sanitizer placement. Placement is static whenever possible, switching to run time when necessary. Run-time taint tracking techniques can be used to track the source of a value, and thus apply appropriate sanitization. However, due to the runtime overhead of run-time taint tracking, our technique avoids it wherever possible.
