## 课程概述

Welcome to Cryptography! Cryptography is the practice and study of techniques for securing communications in the presence of third parties. You will learn how to protect information in order to ensure its integrity, confidentiality, authenticity, and non-repudiation. You will come out with a basic understanding of cryptographic concepts and how to apply them, implement secure protocols, key management concepts, key administration and validation, and Public Key Infrastructure. Course Objectives 1. Apply the fundamental concepts of cryptography 2. Describe the difference between symmetric and asymmetric cryptography 3. Define the basic requirements for cryptography 4. Identify processes to support secure protocols 5. Describe the process for implementing cryptographic systems 6. Define key management concepts 7. Define Public Key Infrastructure 8. Identify processes for key administration and validation 9. Describe the implementation of secure protocols...

One of the most important security topics for CIA, Authentication & Non-repudiation. Absolutely must have knowledge as a security stakeholder. Practical skills throughout the course. Thanks.

If you have an IT bachelor degree, then don't enroll in it.

It's only theoretical, and doesn't deserve $200. 创建者 Dominic P Jul 26, 2022 It's a very high level course, but that could be forgiven. What is annoying is that the information presented and information tested during intermediate quizes is out of sequence. Furthermore, some test questions are formulated very unclearly. Finally, the final test based on open questions leaves too much room for incomplete answers while still getting all the points. Worse, when grading, sometimes you have options to only give 2,5/5 or 5/5 points, yet not 0/5 for completely wrong questinos... All in all this results in even lower value of the accreditation. 创建者 FAROOQ K Sep 3, 2019 IT HAS BEEN TWO DAYS AND THE FINAL ASSIGNEMENT ANS PEER REVIEWS WOULD NOT START OR DISPLAY ANYTHING. No information who to call or contact to resolve. Waste of$200

Great course content, interactive, instructor is very knowledgeable and quiz after every module is good to assess our-self with the concepts which we learned and project is something unique experience when it compare to any online training program, Overall its a great learning experience. Thank you the entire team of Coursera and ISC2.

A very good course to learn about cryptography, very simple with a lot of knowledge. Regarding teacher is very practical have a lot of examples. Regarding the information it has the possibility to take notes, download information and have a summary of the videos also you can see the text of the speaker.

There was nothing easy about this course, perhaps that is what makes it so good. There is a lot of information to process, I have a better understanding of cryptography and the role it plays in maintianing information integrity and confidentiality.

some of the questions in the final test were not really discussed during the course or maybe briefly mentioned and not in details

More of a theoretical course. Content does not cover anything on how these concepts can be used in practice. A week of practical usage and an assignment based on it would have made it much better.

An asset is worth $10,000. The likelihood of an attack is once every two years with an expected impact of 80% damage. The risk acceptance level is$2000. A control that would reduce the risk to $1000 per event is available at an annual cost of$4000. Should the company implement the control? Calculate SLE, ARO and ALE. Then calculate residual risk once the control is implemented.
