Web Security

Overview

This course is a comprehensive overview of web security. The goal is to build an understanding of the most common web attacks and their countermeasures. Given the pervasive insecurity of the modern web landscape, there is a pressing need for programmers and system designers to improve their understanding of web security issues. We'll be covering the fundamentals as well as the state-of-the-art in web security.

Topics include: Principles of web security, attacks and countermeasures, the browser security model, web app vulnerabilities, injection, denial-of-service, TLS attacks, privacy, fingerprinting, same-origin policy, cross site scripting, authentication, JavaScript security, emerging threats, defense-in-depth, and techniques for writing secure code. Course projects include writing security exploits, defending insecure web apps, and implementing emerging web standards. Instructor: Feross Aboukhadijeh (https://feross.org)

Wow Meticulous in keeping the workplace clean and tidy. Charlotte makes a habit of keeping own area clean and hazard-free and also assists and encourages others to do the same. Reacts quickly and decisively in an emergency, keeping a cool head and effectively leading others. Applies professional experience and/or knowledge of people expertly to forecast outcomes with at least 90% accuracy. Others trust his judgement because the choices have usually been good. Late on fewer than 3 occasions in 6 months.
