Responsible Domains as below:

1. Monitoring & Detection

• Monitor security alerts from various sources, including SIEM (Security Information and Event Management), EDR (Endpoint Detection and Response), firewalls, and IDS/IPS systems.
• Triage incoming alerts to distinguish between benign events and genuine security incidents.
• Maintain and tune use cases within the SIEM to reduce false positives and improve detection capabilities.
  
  

2. Incident Response & Management

• Lead the technical response to security incidents, including malware outbreaks, ransomware, phishing campaigns, data leaks, and unauthorized access.
• Perform digital forensics, including disk and memory analysis, to determine the root cause and scope of an incident.
• Contain, eradicate, and recover from security incidents, ensuring business continuity.
• Document every step of the incident lifecycle, creating detailed after-action reports and timelines.
  
  

3. Threat Hunting & Analysis

• Proactively search for signs of advanced persistent threats (APTs) or malicious activity that may have evaded existing security controls.
• Analyze threat intelligence feeds to understand the current threat landscape and anticipate potential attacks against the organization.
  
  

4. Communication & Reporting

• Communicate technical findings to non-technical stakeholders, including management and legal teams, during active incidents.
• Prepare post-incident reports that include root cause analysis, lessons learned, and remediation recommendations.
• Escalate critical incidents according to the incident response plan.
  
  

5. Process Improvement

• Recommend and implement improvements to security tools, policies, and playbooks based on lessons learned from incidents.
• Collaborate with the IT and Development teams to ensure vulnerabilities are patched and configurations are hardened.
