Being able to troubleshoot security issues is essential to ensuring fully functional systems in the cloud. In this course, you'll examine some of the common causes of security issues. First, you'll learn to troubleshoot security issues due to missing or incomplete privileges, authentication or authorization issues, or network and directory security group issues. Next, you'll explore how to troubleshoot security issues due to expired, revoked, compromised, or misconfigured keys and certificates or due to misconfigured or misapplied policies. You'll then move on to learn how to troubleshoot and identify security concerns due to unencrypted data, data breaches, misclassification of data, lack of protocol encryption, and insecure ciphers. Finally, you'll also learn to troubleshoot and identify security concerns due to exposed endpoints, misconfigured security appliances, and unsupported protocols, as well as how to deal with internal or external attacks. This course is one of a collection of courses that prepares learners for the CompTIA Cloud+ (CV0-003) certification.
