Cyber Security Analyst

ShadowFox | Internship | Chennai, Tamil Nadu, India · Remote

• Confidential Operating Environment: Worked inside a restricted security setup where access, data visibility, and actions were tightly controlled. Followed security policies, escalation protocols, and non-disclosure standards to ensure sensitive systems and information were handled responsibly and professionally.
• Security Monitoring & Visibility: Continuously monitored system, user, endpoint, and network activity to identify abnormal behavior. Focused on early indicators such as unusual login patterns, suspicious process activity, traffic anomalies, and deviations from normal baselines.
• Alert Validation & Triage: Reviewed and analyzed incoming alerts to determine relevance and severity. Used log correlation, contextual checks, and known attack patterns to filter false positives and prioritize alerts that required investigation or escalation.
• Initial Investigation & Analysis: Conducted first-level investigations by examining authentication logs, system events, endpoint activity, and access records. Assessed scope, potential impact, and urgency before handing off confirmed or high-risk issues.
• Incident Workflow & Documentation: Supported incident-handling processes by documenting findings clearly, maintaining case records, and escalating issues in line with defined procedures. Ensured all actions were traceable, audit-ready, and aligned with operational standards.

Tools Used: SIEM platforms (Splunk / Elastic) for log analysis, endpoint protection (Microsoft Defender for Endpoint) for host-level visibility, network security controls (firewalls & IDS/IPS) for traffic monitoring, vulnerability scanning (Nessus) for identifying exposure, and threat intelligence (VirusTotal) for indicator validation.
