I have worked using Logs, SCCM, Right Click Tools to identify and remediate vulnerabilities. Additionally I have used Tenable Nessus to understand severity and best practice in remediation of vulnerabilities. After understanding and gaining experience with frequent vulnerabilities I began using PowerShell scripting to automate much of the remediation process. Lastly, I used SCCM and my understanding of how it works to find issues within the configuration of SCCM which resulted in some vulnerabilities not being auto remediated. After identifying these issues multiple vulnerabilities were automatically remediated from SCCM directly. Show less
