Longer passwords increase the number of possible keys making it, Encryption is essential for every day life and activity, The "strength" of encryption is related to how easy it is to crack a message, assuming adversary knows the technique but not the exact "key". Definitions of cryptography, encryption, decryption, cracking/breaking an encryption, cipher, etc. Antivirus software usually keeps big lists of known viruses and scans your computer looking for the virus programs in order to get rid of them. Note that the Explore PT prep unit includes additional resources that will help students prepare for the task. Implementing cybersecurity has software, hardware, and human components. Code of Practice for Cyber Security in the Built Environment. Understand the relationship between cryptographic keys and passwords. Enterprise. As a result an alphabetic shift is often referred to as the Caesar Cipher. You cannot break it so you are encouraged to let students play and investigate to figure out how the tools work. Distributed denial of service attacks (DDoS), Viruses / Antivirus software and firewalls. However, when aided with computational tools, a random substitution cipher can be cracked by a novice in a matter of minutes. But what it does is bit of a mystery! Most of those people were also impacted by the cyber incident involving background investigations records; approximately 600,000 individuals were impacted only by the cyber incident involving personnel records.

As part of wrap up the major points we want to draw out are: Here are a couple of thought-provoking prompts you can use to bring closure to the lesson and as an avenue to draw out the points above. How did you get interested in computer science? freeCodeCamp is a donor-supported tax-exempt 501(c)(3) nonprofit organization (United States Federal Tax Identification Number: 82-0779546) Our mission: to help people learn to code for free. Luckily, in choosing their topics, students will likely have begun to identify resources they can use in completing their project. shorter? If necessary provide context of some facts about the Internet: Secrecy is a critical part of our lives, in ways big and small. Goal: let students explore for 5-10 minutes to see if they can discover what the tool is showing them and allowing them to do. “Encryption” is a process for transforming a message so that the original is “hidden” from anyone who is not the intended recipient. Once you've done one, it only takes a matter of seconds to do others. With tools it becomes trivial, as we'll see next. The video touches on types of cybercrimes and cyber attacks NOT covered in the How Not To Get Hacked - Web Resource article but are still vocabulary that students need to know, specifically DDoS attacks and how they work. Ask the students questions and leave time for Q&A. (It should look like the screen shown below), Figure out what is going on in this new version of the tool. If you want to, enter you own message, encrypt it, and have a friend decrypt it. Presenting and cracking a caesar cipher should go pretty fast. There is a page in Code studio which recaps terminology (encryption, decryption, crack, cipher, Caesar ciper) and poses the next problem. Don't rush it, but don't linger on cracking caesar ciphers. Students are not creating any kind of computational artifact. Some categories and topics have been supplied ahead of time. The need for secrecy when sending bits over the Internet is important for anyone using the Internet. The process of encoding a plain text message in some secret way is called Encryption. For 50 years and counting, ISACA ® has been helping information systems governance, control, risk, security, audit/assurance and business and cybersecurity professionals, and enterprises succeed. Showing top 20 occupations for cybersecurity. The video touches on a number of topics that students might choose to research later: Distribute: Give students copies of Rapid Research - Cybercrime - Activity Guide What information is being presented to you? You should move on to cracking random substitution relatively quickly. Showing top 20 occupations for cyber security. Students try their own hand at cracking a message encoded with the … More sophisticated scams can make websites and email look very similar to the real thing. Emphasize the need for clarity in their writing, and remind them that everything must fit on a single page. Students are not describing the beneficial or harmful effects of an innovation / event. How much easier is it to crack a Caesar cipher than a random substitution cipher? With this simple encryption technique it only took a few minutes to decode a small message. REMINDER: Discovery-based introduction of tools in a nutshell: This widget, like all others, are meant as a learning tool. Did it take longer than you thought? 1. Review terminology about cybersecurity and crime that is relevant for the AP CS Principles Exam and 2. It provides social context which you may want to bring to your classroom.

Choose one or more. If students are struggling to start here are a few strategy suggestions: If you'd like your students to read a little bit about Historical Cryptography and cracking ciphers, check out 'Substitution Ciphers and Frequency Analaysis' in Blown to Bits, Chapter 5 - Reading pp. See how codes can protect your online secrets and what motivates hackers to hack. If you received a notification letter and 25-digit PIN code … Remember the letters aren't randomly substituted - the alphabet is just shifted. The annotations given here should provide enough depth for the kinds of responses expected of students. When you see the little lock icon and, SSL (secure sockets layer) and TLS (transport layer security) use. Complete One-Pager: Students should find this aspect of their project most familiar. Stream high-quality videos and courses on various topics of cybersecurity and take your career to the next level! Do the students have any questions for you. Crack a message encrypted with a Caesar cipher using a Caesar Cipher Widget, Crack a message encrypted with random substitution using Frequency Analysis, Explain the weaknesses and security flaws of substitution ciphers. Viruses can be used as a Bot Net to trigger a DDoS-style attack, or they can spy on your computer activity, such as capturing all the keystrokes you make at the computer, or websites you visit, etc. The prompts are similar in style and content to prompts students have already seen. What if the message were longer BUT you had a computational tool to help you?! We are a national non-profit providing services and support for women and marginalized groups interested in a cybersecurity career. What about a random substitution cipher? If you are running out of time, assigning some of these terms for homework might be a good way to review and kick off the next day. Share a story about how tech affects everyone. This message was encrypted using a Caesar Cipher (an "alphabetic shift"). Closest matches are shown first. cyber security. Review Activity Guide and Rubric: At the beginning of the project, emphasize the importance of reviewing the one-pager template and rubric. … In this video, hear how our excellence in code-making and code … A "firewall" is simply software that runs on servers (often routers) that only allows traffic through according to some set of security rules. Developing strong encryption relies on knowledge of problems that are “hard” for computers to solve, and using that knowledge to encrypt messages. Conducting Your Research: This document is intended to serve primarily as a guide to students for identifying online sources of information. Explain why encryption is an important need for everyday life on the Internet. Find a small word and try alphabetic shifts until it's clear that it's an English word. If we are to create a secure Internet, we will need to develop tools and protocols which can resist the enormous computational power of modern computers.
