 Sample Answer 


  Example response for question delving into Security Monitoring with the key points that need to be covered in an effective response. Customize this to your own experience with concrete examples and evidence

  •  Monitoring Security Logs: I monitor security logs by using a SIEM (Security Information and Event Management) system that collects and aggregates logs from various sources, such as firewalls, intrusion detection systems, and antivirus software
  •  Analyzing Security Events: I analyze security events by reviewing the logs for any suspicious or anomalous activities. I look for patterns, trends, and indicators of compromise to identify potential security incidents
  •  Incident Response: If a security event is identified, I follow the incident response process to investigate and mitigate the incident. This includes gathering additional information, containing the incident, and implementing necessary remediation measures
  •  Threat Intelligence: I leverage threat intelligence feeds and databases to enhance my analysis of security logs and events. This helps me identify known malicious indicators and tactics used by threat actors
  •  Log Management: I ensure proper log management by configuring log sources to send relevant logs to the SIEM system, setting up log retention policies, and regularly reviewing log storage capacity to prevent log overflow
  •  Reporting & Documentation: I document my findings and analysis in incident reports, including details of the security event, its impact, and the actions taken to mitigate it. I also provide recommendations for improving security based on the analysis of logs and events
