With the introduction of wide-ranging and impactful legislation and requirements for privacy and data security (like GDPR), a radical, yet powerful cryptography-based solution is gaining traction and relevance. The “Untrusted Server” model assumes the Web application backend will never have access to customers’ data in plaintext, thereby negating almost all impact of data breaches – as the server is unable decrypt users’ data, so is the attacker.
The purpose of this course is to introduce the “Untrusted Server” security model, its strengths and limitations, as well as proper security-oriented development procedures and to demonstrate practical security concerns in the process, e.g. threat modelling, host hardening, proxying, etc.
During the training, participants will start from a skeleton project and complete a fully-functional secure file sharing service in Node.js and will incrementally deploy different security mechanisms and protections.
