Alert Analysis
The object of Alert Analysis is to examine and understand the nature of an alert generated. The goal is to determine the significance of the alert, identify potential threats or anomalies, and initiate the process of incident identification.
Process:
Trigger Identification:
- Determine the specific trigger or event that led to the generation of the alert.
- Identify the source or context that initiated the alert, such as a security event or system log entry.
Correlation Check:
- Check if there are multiple alerts correlated with the same incident.
- Analyze the relationships between correlated alerts to understand the broader context of the incident.
Malicious Activity Assessment:
- Assess whether the alert indicates potential malicious activity or security threats.
- Look for patterns or indicators that suggest unauthorized access, malware presence, or other security concerns.
Relevance to Security Policies:
- Evaluate the alert’s relevance to established security policies and rules.
- Determine if the observed activity aligns with acceptable network behavior or if it deviates from defined security standards.
Severity Evaluation:
- Assess the severity level assigned to the alert.
- Consider the potential impact on the organization’s assets, data, and overall security posture.
Initial Triage:
- Perform an initial triage to prioritize alerts based on criticality.
- Determine which alerts require immediate attention and which can be investigated in subsequent stages.
Documentation of Initial Findings:
- Document initial findings and observations related to the alert.
- Note any unique characteristics or information that may be relevant for further analysis.
Flagging for Further Investigation:
- Identify alerts that warrant deeper investigation and analysis.
- Flag alerts that may indicate a potential incident or security breach.
