The analyst will also provide technical guidance and mentorship to junior SOC team members. Key Responsibilities Monitor network, endpoint, system, application, and identity telemetry for potential security threats. Investigate IDS/IPS and EDR alerts, security logs, system events, and network traffic to identify suspicious or malicious activity. Perform second-level analysis of escalated alerts, determine severity and relevance, distinguish legitimate threats from false positives, and document findings. Use SIEM and log-analysis platforms such as Splunk, Elastic/OpenSearch, Kibana, and Microsoft Sentinel to investigate and correlate security events. Operate, tune, and recommend improvements to SIEM, EDR, endpoint security, and other SOC technologies. Support Microsoft Defender and related Microsoft security technologies for alert investigation, containment, and response. Develop threat-hunting and detection strategies based on emerging threats, observed activity, and established attack frameworks. Identify and integrate additional security data sources to improve monitoring and detection coverage. Develop Python 3 and PowerShell scripts to automate detection, enrichment, investigation, response, and security data analysis. Support firewall administration, including security policy enforcement and ruleset maintenance. Incorporate AI-assisted security capabilities into investigation, detection, analysis, automation, and response workflows. Serve as a technical first responder for suspected and confirmed cybersecurity incidents. Perform endpoint, identity, network, log, and system-level analysis to determine incident scope, impact, and potential root cause. Support incident containment, eradication, evidence preservation, and recovery activities. Conduct first-responder-level digital forensic analysis and breach assessment. Prepare clear incident documentation and communicate findings to technical leadership and relevant stakeholders. Configure and review vulnerability scans and analyze identified security weaknesses. Prioritize vulnerabilities based on severity, exploitability, exposure, and business impact. Coordinate remediation activities with infrastructure, application, networking, and system owners. Validate remediation activities and monitor patching effectiveness for critical findings. Mentor junior SOC analysts in alert investigation, log analysis, incident documentation, and escalation practices. Assist with the onboarding, training, and day-to-day technical oversight of junior security team members. Develop and maintain SOC runbooks, operating procedures, investigation workflows, and escalation guidelines.
