Answer

Log analysis is a critical component of detecting early signs of a breach, as it helps identify anomalies and suspicious activities. Following a structured approach ensures thorough examination and timely detection of potential threats.

Access the SIEM (Security Information and Event Management) dashboard to aggregate and visualize log data from various sources.
Identify and prioritize logs based on critical systems, high-value assets, and known threat vectors.
Search for anomalies such as unusual login attempts, unexpected data transfers, and changes to system configurations.
Correlate events across different logs to identify patterns indicative of a breach, such as lateral movement or privilege escalation.
Document findings and escalate any suspicious activities for further investigation and response.

Additional Comment:

Use automated tools to enhance log analysis efficiency and accuracy.
Regularly update detection rules and thresholds based on the latest threat intelligence.
Ensure logs are retained according to compliance requirements and organizational policies.
Train staff on recognizing signs of compromise and using log analysis tools effectively.
