 # Ethics
 *Timeline: 35 hours*
 
-This course provides an introduction to ethics in engineering and technology.
-- [Ethics, Technology & Engineering](https://www.coursera.org/learn/ethics-technology-engineering), 18 hrs
+Ethics in Technology is an open textbook that introduces students to the ethical challenges posed by modern digital tools and innovations. It covers topics such as privacy, cybersecurity, artificial intelligence, and social responsibility, encouraging learners to think critically about the role of technology in society.
 
-This course will introduce the various types of U.S. intellectual property: patents, which cover inventions and process innovations; copyright, which protects original works of authorship; and trademarks, which protect a business’ commercial identity as the source of valuable goods and services. You will then explore case studies of how global businesses have used intellectual property law to generate enormous value from these intangible assets.

-This course is designed to introduce data privacy to a wide audience and help each participant see how data privacy has evolved as a compelling concern to public and private organizations as well as individuals. In this course, you will hear from legal and technical experts and practitioners who encounter data privacy issues daily. This course will review theories of data privacy as well as data privacy in the context of social media and artificial intelligence. It will also explore data privacy issues in journalism, surveillance, new technologies like facial recognition and biometrics.

-# Secure Coding Practices
-*Timeline: 52 hours*
-
-Through these courses, you will cover the principles of secure coding, concepts of threat modeling, cryptography, and exploit vulnerabilities in C/C++ or Java languages, all of which will prepare you to think like a hacker and protect your organizations information. The courses provide ample practice activities including exploiting WebGoat, an OWASP project designed to teach penetration testing.
