As a SOC Analyst L2, you will lead deeper investigations of escalated cases, confirm incidents, determine scope and impact, drive containment actions with internal teams, and produce high-quality technical communications and post-incident outputs. You will also contribute to detection improvement (tuning, new detections, playbook updates).
Responsibilities:
- Take escalations from L1 and perform in-depth investigations: hypothesis-driven analysis, evidence validation, scoping, impact assessment, and timeline building.
- Correlate telemetry across endpoint (EDR), Windows/Linux, AD, firewall/proxy/DNS/IDS, and (when applicable) cloud logs.
- Recommend and/or coordinate containment actions (host isolation, credential resets, IOC blocks, temporary control changes) following change control and governance.
- Determine severity and communicate clearly in English to technical stakeholders; provide concise executive-style updates when required.
- Identify detection gaps and drive improvements: reduce false positives, close false negatives, propose new rules/use cases.
- Ensure evidence integrity and proper documentation, coordinate handoffs with IR, IT Ops, Network, and Cloud teams.
- Produce post-incident deliverables: probable root cause, lessons learned, and preventive actions.
Requirements
- 2–5 years in SOC/IR/Blue Team (or equivalent demonstrated incident-handling experience). Solid fundamentals in networking: TCP/IP, DNS, HTTP/S, VPN, NAT.
- EDR investigations (process trees, persistence, LOLBins behavior, containment workflows).
- Windows/AD triage (authentication patterns, suspicious logon behavior, account activity) and Linux triage.
- Network analysis and security controls (firewall/IDS/proxy/DNS), recognizing anomalous patterns.
- Proven ability to produce defensible scoping and timelines based on evidence.
- High documentation standards and the ability to perform under pressure.
- Threat hunting experience and MITRE ATT&CK mapping.
- Detection engineering exposure (Sigma/YARA at a basic/intermediate level), use-case design, and SIEM correlation strategy.
- Basic forensics capabilities (acquisition concepts, triage artifacts, memory/disk fundamentals).
- Certifications aligned to Blue Team / IR (e.g., GCIH/GCIA, BTL2, SC-200, etc.).
- Strong spoken and written English (B2-High/C1 preferred) — able to lead technical calls, write incident summaries, and investigation notes.
