The Update Framework (TUF) helps developers to secure new or existing software update systems, which are often found to be vulnerable to many known attacks. TUF addresses this widespread problem by providing a comprehensive, flexible security framework that developers can integrate with any software update system. The framework can be easily integrated (or implemented in the native programming languages of these update systems) due to its concise, self-contained architecture and specification. Developers have so far implemented the framework in the Python, Go, Ruby, and Haskell programming languages.
