The systems we support are hosted using Azure, with some baremetal systems that are due to be migrated still in operation.

EquifaxSenior Technical Systems Analyst
Jan. 2018 - Jan. 2021Alpharetta, Georgia, United StatesWorking as a Senior Technical Analyst in the Infrastructure As A Service (IAAS) organization with the NixSA team who maintained 10,000 Linux based systems. The systems were built using a mixture of SUSE 11 & 12, CentOS 6 & 7, and Red Hat (RHEL) 5, 6, and 7. Brought in to help build out their patch management infrastructure, define vulnerability remediation methods, and develop standard processes to minimize the risks to critical systems. This included structuring those systems into operational lifecycles, creating patch groups based on those lifecycles, and coordinating patching operations for our offshore teams. Patch management and patch group creation was done using Suse Manager and two different installations of Katello, for CentOS and RHEL systems. Managed the patch management systems to ensure they were synced with the OS vendors to provide the latest patches as they were available. Systems are scanned weekly using Rapid7, and detailed reports provided to the application owners showing needed patches, or vulnerabilities that required system/application configuration changes. Analyzed these reports to assist the application owners in keeping with SLAs for vulnerability remediation, and to determine what required patching alone, and what required configuration changes as well. Worked with external audit firms, or government entities, to validate adherence to patch standards, and to make sure that processes were fully documented as directed by Senior Leadership.
