• Work hands-on with SIEM platforms such as Microsoft Sentinel, Splunk, IBM QRadar, or similar tools.

• Use endpoint detection and response (EDR) solutions such as Microsoft Defender for Endpoint, CrowdStrike, or similar platforms.

• Investigate alerts using endpoint telemetry, authentication logs, network logs, and cloud security events.

• Develop or fine-tune detection rules, alert thresholds, and correlation logic to improve threat detection.

• Use security dashboards, queries, and investigation tools to identify and analyze potential threats.

4. Threat Hunting & Vulnerability Management

• Perform proactive threat hunting to identify suspicious activities that may not trigger standard security alerts.

• Analyze indicators of compromise, threat intelligence feeds, and emerging attack techniques.

• Support vulnerability identification, prioritization, remediation tracking, and validation.

• Assist in investigating security weaknesses and recommend practical mitigation measures.

• Apply knowledge of common attack techniques, including those described in the MITRE ATT&CK framework.

5. Security Operations & Documentation

• Hands-on experience with one or more SIEM platforms, such as Microsoft Sentinel, Splunk, or IBM QRadar.

• Experience with EDR tools such as Microsoft Defender for Endpoint, CrowdStrike, or similar solutions.

• Strong knowledge of security event analysis, log correlation, incident triage, and root-cause investigation.

• Experience responding to phishing, malware, endpoint compromise, suspicious authentication, and unauthorized access incidents.

• Working knowledge of network security, endpoint security, identity and access management, and cloud security fundamentals.

• Understanding of vulnerability management and security remediation practices.

• Strong troubleshooting, analytical, and problem-solving skills.

• Good communication skills and the ability to collaborate effectively with technical teams.

Preferred Qualifications

• Experience with Microsoft Sentinel, Microsoft Defender XDR, CrowdStrike, Splunk, or IBM QRadar.

• Familiarity with MITRE ATT&CK, threat hunting, and detection engineering.

• Knowledge of incident response playbooks and digital forensics fundamentals.

• Exposure to AWS, Microsoft Azure, or other cloud security monitoring tools.

• Familiarity with scripting or query languages such as PowerShell, Python, KQL, or SPL.

• Relevant certifications such as Security+, CySA+, GCIH, GCIA, or equivalent cybersecurity certifications.
