À propos de Marwane

Je suis un analyste SOC/CSIRT expérimenté, au croisement de la détection avancée, de la réponse à incident et de la cyber threat intelligence, avec une forte spécialisation en création de règles de détection sur mesure et en exploitation avancée des SIEMs. J’interviens en première et troisième ligne pour détecter, investiguer et neutraliser les menaces les plus sophistiquées.

Mes domaines d’expertise :
• Threat Hunting proactif sur EDR (CrowdStrike Falcon, SentinelOne, etc.)
• Détection personnalisée : création de règles (SIGMA, YARA, KQL, AQL, Falcon Query Language…)
• Manipulation avancée de SIEMs (QRadar, Splunk, Elastic, LogScale) : parsing, règles de corrélation, dashboards, filtres personnalisés
• Investigation forensique (mémoire, disques, artefacts Windows/Linux, analyse de logs)
• Analyse et réponse à incidents : ransomware, attaques LotL, accès initial, élévation de privilèges, mouvements latéraux
• Enrichissement d’IoCs, détection des TTPs adverses (MITRE ATT&CK, CTI, OSINT)
• Production de playbooks DFIR, rapports techniques & recommandations durcies

Ce que j’apporte :
• Une capacité à transformer la visibilité brute en détection ciblée et actionnable
• Une approche offensive/défensive, ancrée dans les tactiques des attaquants
• Une expertise éprouvée dans l’optimisation des pipelines SIEM/EDR/SOAR
• Une autonomie complète sur des environnements critiques et des contextes sensibles

Disponible pour des missions ponctuelles ou longues, sur site ou à distance, pour :
• Améliorer la couverture de détection
• Renforcer les capacités du CSIRT/SOC
• Réagir face à une compromission
• Structurer une stratégie défensive moderne

    Paris, France
    Proactively monitor enterprise systems and networks using industry-leading SIEM and EDR technologies (QRadar, Azure Sentinel / Defender, CrowdStrike) to detect early indicators of compromise, advanced persistent threats, and anomalous behavior. Conduct in-depth digital forensic investigations across Windows and UNIX environments to uncover root causes, trace attacker movements, and collect admissible evidence for potential legal escalation. Orchestrate rapid incident containment and mitigation, leveraging real-time intelligence and automation to neutralize threats and minimize business impact. Collaborate seamlessly with cross-functional teams—including internal CSIRT, global IT security teams, external partners, service providers, and law enforcement when necessary—to coordinate end-to-end incident response. Continuously track emerging threats, vulnerabilities, and adversary tactics (TTPs) to enhance threat models and inform detection strategy. Engineer advanced detection capabilities, developing tailored signatures, YARA rules, and correlation logic for intrusion prevention systems (IPS), malware detection platforms, and SIEMs—optimizing visibility across hybrid infrastructures.
