In the Introduction to Security course, it has become a tradition for students to choose the topic of the final class. This year, we’re taking the voting process to the next level! Cast your vote by sending us a handwritten postcard. Every properly submitted postcard received before the deadline below will be counted.

Voting Method: Sending a Postcard

  1. Pick your preferred topic for the last class from the list below or from the proposals shared during the lecture.
  2. Clearly write the topic you want to vote for.
  3. Feel free to decorate the postcard—stickers, drawings, glitter—just keep your vote legible.
  4. Mail the postcard using regular postal service with enough time for delivery before the deadline. International mail can take weeks.
