• Conduct regular vulnerability scans of Linux systems using tools such as Nessus or Qualys, and prioritize remediation based on risk severity.
• Evaluate CVEs and security advisories (e.g., from NVD, RedHat, Ubuntu Security) for applicability to the environment and communicate risk to stakeholders.
• Administer and audit user accounts, sudo privileges, SSH key management, configurations across Linux infrastructure.
• Configure and maintain centralized logging pipelines for Linux systems using syslog-ng, rsyslog, Fluentd, or the Elastic Stack (ELK).
