Course description
Do you want to know more about protecting your data on your computer? Would you like to see the ins and outs of how that happens? Dive into cryptography and learn about encryption algorithms including 3DES and AES. Understand the difference between symmetric encryption and asymmetric encryption, which is a better solution to use in different circumstances, and why. We’ll explore some of the tools used to secure data both on your hard drive and through emails, as well as focus on the integrity of your data utilizing hashing to authenticate downloads. Finally, we’ll examine public key infrastructure to see how it works under the hood to keep online shopping, banking, and other transactions secure. This course is part of a series covering the CompTIA Advanced Security Practitioner (CASP).
Prerequisites
This course assumes that you have familiarity with information technology, basic networking, and basic security concepts. No scripting or “hacking” experience is required. Having windows command line experience as well as having administrative rights on your machine will be helpful.
