Quality can be defined as fitness for purpose.
Code reviews and interface testing, are key elements in ensuring software quality.
Software controls come in various flavors and have many different goals. They can control input, encryption, logic processing, number-crunching methods, inter-process communication, access, output, and interfacing with other software. Software controls should be developed with potential risks in mind, and many types of threat models and risk analyses should be invoked at different stages of development. The goals are to reduce vulnerabilities and the possibility of system compromise.
