What This Document Is
This is a lab assignment for Introduction to Computer Networks (CSE 473S) at Washington University in St. Louis, specifically Homework 8E. It focuses on the practical application of email security principles, centering around digital certificates, encryption, and digital signatures. The assignment requires students to engage with email clients and understand how to securely communicate using these technologies. It’s a hands-on exercise designed to reinforce theoretical concepts learned in the course.
Why This Document Matters
This assignment is crucial for students aiming to understand the real-world implementation of network security. It’s particularly valuable for those pursuing careers in cybersecurity, network administration, or software development where secure communication is paramount. Successfully completing this lab will demonstrate a student’s ability to configure email clients for secure messaging and verify the authenticity of senders. It’s best utilized *after* covering the foundational concepts of cryptography and email protocols in lectures.
Common Limitations or Challenges
This assignment focuses on the *how-to* of implementing email security with specific software. It does not delve deeply into the underlying mathematical principles of encryption algorithms or the broader policy implications of digital signatures. Students will need to have a working knowledge of email client software (Outlook, Gmail, Thunderbird, etc.) and basic computer troubleshooting skills. The assignment assumes access to a computer with internet connectivity and the ability to install and configure software.
