Cryptographers far from enemy lines have long helped win shooting wars by cracking enemy codes—and in the new world of cyber warfare, cryptography has become the first line of defense for hundreds of millions of civilians worldwide. In this 21-video course, you will learn just how cryptography and encryption protect sensitive data, both in transit and at rest. Learners are given important information about public key infrastructure (PKI) hierarchy and lifecycles; protection in UFS (Ultra Flash Storage) and Bitlocker; and on Linux and cloud storage. Learn about the hashing process, including how to generate file hashes for Linux and Windows. Then learn about using SSL (secure sockets layer) and TLS (Transport Layer Security) to secure network traffic, cloud certificate authority (CA) deployment, and certificate issuance. Next, learn how to configure custom encryption keys for cloud storage and how to configure a Microsoft IIS web site with a PKI certificate. The course helps to prepare learners for CompTIA+ Cybersecurity Analyst+ (CySA+) CS0-002 certification exam.
