Monitored enterprise security infrastructure using SIEM platforms to detect suspicious activities, anomalous behavior, and potential security incidents. Performed security alert triage and investigation across multiple log sources including endpoints, firewalls, authentication systems, DNS logs, and network devices. Investigated endpoint-based threats using EDR tools, analyzing process trees, registry modifications, persistence mechanisms, and suspicious file executions. Conducted phishing incident investigations including email header analysis, malicious attachment inspection, URL reputation checks, and IOC extraction. Correlated security events across multiple telemetry sources to detect multi-stage attack campaigns and lateral movement attempts. Leveraged threat intelligence feeds and OSINT platforms to enrich investigations and validate malicious indicators of compromise (IP addresses, domains, file hashes). Performed investigations aligned with MITRE ATT&CK techniques to identify adversary tactics and attack behaviors. Investigated suspicious authentication activities including brute-force attempts, impossible travel events, and account compromise scenarios. Conducted network traffic analysis to identify abnormal outbound connections and potential command-and-control communications. Assisted in SIEM rule tuning and detection logic improvements to reduce false positives and enhance detection capabilities. Participated in threat hunting exercises to proactively identify suspicious patterns and potential stealthy threats within the environment. Investigated malware-related alerts by analyzing file reputation, process execution patterns, and endpoint telemetry. Documented security incidents, investigation steps, root cause analysis, and remediation recommendations. Collaborated with SOC L2/L3 teams, incident response teams, and IT teams to coordinate containment and remediation actions. Monitored privileged account activities and investigated potential misuse of administrative privileges. Supported vulnerability management activities, reviewing vulnerability scan reports and assisting with remediation tracking for critical vulnerabilities. Contributed to SOC operational improvements, including playbook development and incident response workflow enhancements. Participated in post-incident reviews and lessons learned sessions to improve SOC detection and response capabilities.
