You will play a key role in threat detection, incident investigation, and forensic analysis by transforming raw logs into actionable insights through dashboards, alerts, and advanced log analysis.Key Responsibilities- Design, implement, and maintain log collection pipelines from multiple sources, including security, infrastructure, cloud, and application systems.- Ensure logs are ingested, parsed, normalized, and retained correctly across SIEM platforms such as FortiAnalyzer, Splunk, CrowdStrike, and others.- Maintain data quality and consistency across all log sources.- Design, build, and maintain dashboards and visualizations to provide visibility into security posture, threats, and operational metrics.- Create, tune, and maintain correlation rules and alerts based on:- Attack patterns- Indicators of compromise (IOCs)- Behavioral anomalies- Custom detection use cases defined by the Information Security Team- Continuously analyze logs to identify suspicious, anomalous, or out-of-the-ordinary behavior.- Proactively hunt for threats by performing advanced log searches and pattern analysis.- Support incident response and forensic investigations by:- Searching historical logs- Reconstructing attack timelines- Identifying entry points, lateral movement, and attacker activity- Collaborate with SOC Analysts, Dev Security, IAM, Threat Hunting, and other security roles during incident investigation and response.- Validate alerts and detections to reduce false positives and improve detection quality.- Ensure all detections, investigations, and findings are properly documented and tracked via tickets (Jira).- Document new procedures or update existing ones for log management, detection, and investigation.- Ensure documentation is accurate, comprehensive, and delivered on time.- Create reports based on SIEM data for operational, technical, and management audiences.- Engage in ongoing training and professional development to stay current with emerging threats, attack techniques, and detection strategies.- Share knowledge and expertise with the team to foster a culture of security awareness and continuous improvement.- Adhere to the organization's policies.- Keep your work organized and traceable through tickets (Jira).Knowledge and skills you need to have- Studies in computer science, telecommunications, cybersecurity, or other related academic fields.- At least 3 years of work experience in SIEM operations, log analysis, or security monitoring roles.- Hands‑on experience collecting and managing logs from multiple sources (endpoints, network devices, servers, cloud services, applications, authentication systems, etc.).- At least 2 years of experience with Splunk is required (operating and configuring rules and settings).- At least 2 years of experience working with CrowdStrike is required.- Experience working with other SIEM and log platforms such as FortiAnalyzer, New Relic, ManageEngine AD Audit, Axonius, or similar.- Experience creating dashboards, visualizations, and reports based on log data.- Experience in defining and tuning alerts and correlation rules.- Knowledge of scripting or query languages used in SIEM platforms (e.G., SPL, KQL, SQL‑like queries).- YARA rules.- Regular expressions (regex).- Familiarity with security tools generating logs, such as firewalls, EDR, IAM, cloud platforms, and application security tools.- Strong analytical mindset with the ability to identify patterns and anomalies in large datasets.- Experience supporting incident response and forensic investigations through log analysis.- Ability to work independently and as part of the Information Security Team under minimal supervision.- Eager to learn and continuously improve detection capabilities.- Strong documentation and reporting skills.- Technical skills:- Solid foundations in networking, operating systems, authentication flows, and cybersecurity.- Ability to understand how logs reflect system and user behavior across different platforms.Additional requirements, not essential but "nice to have"- Any cybersecurity certification.- Experience with log normalization standards and detection methodologies.- Familiarity with MITRE ATT&CK and threat detection frameworks.- Experience with threat hunting activities.- Familiarity with forensic analysis concepts and incident response workflow#J-18808-Ljbffr
