When approaching troubleshooting in a Linux environment, I typically start by analyzing system logs using tools like 'tail' and 'grep' to pinpoint issues. I also perform checks on system services with 'systemctl', and validate configurations to ensure everything is set up correctly. This systematic approach helps in isolating problems effectively.

Patch management is crucial as it keeps systems secure and minimizes vulnerabilities. In my previous roles, I ensured timely application of security patches using 'yum' for Red Hat systems. Regular patch management not only secures our servers but also improves performance stability.

In managing compliance, I conduct regular audits against DISA STIG checklists, automate scans with SCAP, and maintain documentation for all compliance-related activities. Engaging with team members to review findings not only strengthens our compliance posture but also educates the team about security best practices.

I have substantial experience with Ansible for automating key processes such as configuration management and application deployment. Utilizing Ansible scripts, I've streamlined tasks like patching and compliance reporting, greatly enhancing operational efficiency while reducing manual errors.

In case of an unexpected server outage, my first step would be to assess the situation by checking server logs and monitoring tools to identify the root cause. Next, I'd communicate with the necessary stakeholders while executing immediate recovery actions, such as rebooting the server or rolling back changes, ensuring minimal downtime.

DISA STIGs are security configuration standards mandated for government systems. I familiarize myself with these requirements to ensure that the systems I manage comply with them. This involves regular audits and vulnerability remediations to maintain compliance and enhance security.

I prioritize tasks based on urgency and impact, often using a task management tool to keep track of assignments. For example, if there's an outstanding security patch that could risk compliance, I would address that before other routine maintenance tasks.

I have a solid background using VMware for virtualization, which has enabled me to efficiently manage server resources and facilitate server migrations. This technology supports high availability and disaster recovery scenarios, which are essential for maintaining business continuity.

I stay current by subscribing to industry blogs, attending webinars, and participating in online forums. Additionally, I pursue certifications and training courses to ensure that I am knowledgeable about the latest tools and best practices in Linux systems administration.

I have experience configuring Red Hat Identity Management for centralized user authentication and role-based access control. In addition, I've managed SELinux policies to enforce security requirements, resolving conflicts while ensuring that system operations are not hindered.
