CompTIA Server+ SK0-005 Practice Question

After deploying a new SIEM, a security administrator finds that the SOC is receiving thousands of individual failed-login alerts every hour from Windows and Linux servers. The team wants to reduce the alert volume without missing a potential brute-force attack pattern. Which SIEM capability should the administrator tune first to achieve this goal?

  • Enable additional log-normalization parsers so every device uses a common schema

  • Create correlation rules with thresholds that group repeated login-failure events before triggering an alert

  • Extend log retention from 30 to 90 days to provide more historical context

  • Forward authentication logs to a cold-storage data lake instead of the SIEM
