ConfErr Description

Configuration file error injection tool ConfErr is a Java based tool for testing and quantifying the resilience of software systems to human-induced configuration errors. ConfErr uses human error models rooted in psychology and linguistics to generate realistic configuration mistakes; it then injects these mistakes and measures their effects, producing a resilience profile of the system under test. The resilience profile, capturing succinctly how sensitive the target software is to different classes of configuration errors, can be used for improving the software or to compare systems to each other. ConfErr is highly portable, because all mutations are performed on abstract representations of the configuration files.Using ConfErr, the development team found several serious flaws in the MySQL and Postgres databases, Apache web server, and BIND and djbdns name servers; they were also able to directly compare the resilience of functionally-equivalent systems, such as MySQL and Postgres.
