Cyber Incident Response Analyst

The Role

As a Cyber Incident Response Analyst, you will be part of the Cyber Defence team that develops and oversees the company's security program, ensuring S&P Global is protected from existing and emerging threats. In close partnership with Security Operations and Threat Intelligence, you will detect, analyze, and decisively respond to security incidents, enrich investigations with timely intelligence, and help drive proactive defences. While based in the UK, you will support response and intelligence needs globally.

Candidates should have a genuine interest in cyber security and a strong grasp of attacker tactics, techniques, and procedures (TTPs). This role requires a detail-oriented, critical thinker who understands how adversaries exploit systems, networks, and people—and how to respond. Experience applying threat intelligence to investigations and to improve detections is highly desirable.

Primary Responsibilities

• Coordinate and triage response to cybersecurity events and conduct forensic analysis across endpoints, networks, cloud, and SaaS.
• Integrate threat intelligence into investigations (e.g., enrich IOCs, map activity to MITRE ATT&CK, identify likely threat actors/TTPs, and assess potential impact).
• Understand the threat landscape through collaboration with industry peers, FS-ISAC, trust groups, and commercial/open-source intelligence, translating insights into actionable recommendations.
• Develop, maintain, and operationalize Incident Response playbooks and SOPs; include PIRs (Priority Intelligence Requirements), collection plans, and feedback loops to refine detections.
• Work closely with the SOC to investigate incidents and deliver containment, remediation, and root cause analysis; produce high-quality intel-informed incident reports.
• Create and tune detections (e.g., SIEM/SOAR, EDR) using intelligence signals (TTPs, behaviors, YARA/Sigma where applicable).
• Produce and present consumable intelligence outputs (e.g., flash alerts, threat overviews, executive briefs) tailored to technical and non-technical stakeholders.
• Contribute to vulnerability/threat surfacing (e.g., emerging CVEs, exploit trends) and advise on risk-based prioritization.
• Deliver actionable incident and hunting metrics to management; assess detection coverage and recommend improvements.
• Follow the end-to-end incident response lifecycle and support post-incident lessons learned with intelligence-driven enhancements.
• Build an understanding of key S&P technology, systems, and business practices to contextualize threats and drive pragmatic defenses.
• Participate in information-sharing activities (e.g., FS-ISAC submissions) in line with TLP and legal/compliance requirements.

Required Qualifications

• Working knowledge of common cyber attacks, tools, and attacker tradecraft; ability to map activity to MITRE ATT&CK and articulate likely TTPs.
• Demonstrated experience handling security events in critical environments and applying intelligence to accelerate triage and response.
• Experience analyzing system, application, and cloud/SaaS logs to investigate security and operational issues; comfort enriching with IOCs and behaviours.
• Hands‑on experience with a SIEM (Splunk preferred) for investigations, alert creation, reporting, and threat hunting.
• Ability to produce clear, actionable intel and incident reports, including executive‑ready summaries and visuals.
• Familiarity with threat intel workflows: collection planning, source evaluation, indicator lifecycle, PIRs, TLP, and feedback loops to detections.
• Experience with one or more TIPs or intel data sources (e.g., MISP, OpenCTI, Recorded Future) and STIX/TAXII concepts.
• 3+ years of information security experience with a focus on incident response, threat hunting, or threat intelligence.
• Excellent communication skills for varied business and technical audiences; strong presentation skills.
• Comfortable working in a fast‑paced environment; passion for cyber security.
• Advanced knowledge of network protocols (TCP/IP, HTTP) and operating systems.

Preferred Qualifications

• Experience in the financial services industry.
• Familiarity with threat hunting techniques (hypothesis‑driven, ATT&CK‑aligned, behavior‑based).
• Windows and Linux administration tools and concepts.
• Understanding of threat actors and the cybercrime ecosystem, including initial access vectors, monetization paths, and supply‑chain/SaaS attack patterns.
• Exposure to malware/TTP analysis at a functional level (family identification, persistence/discovery behaviors) and creation of detections (e.g., Sigma/YARA) is a plus.
• Experience producing finished intelligence products (tactical through executive) and briefing senior stakeholders.
• Relevant certifications (e.g., GCTI, GCFA/GCFR, GCIH, FOR578) or equivalent experience.
• Familiarity with information‑sharing standards and practices (FS-ISAC, TLP) and legal/compliance considerations.
• Knowledge of cloud provider threat models and telemetry (AWS, Azure, GCP, M365/SaaS).
• Second language and/or geopolitical awareness for actor context is a plus.
