Core Responsibilities

Primary Functions

Monitor multiple security telemetry sources (SIEM, EDR, NDR, firewall and proxy logs, cloud logs, email gateways) 24x7 to detect anomalous activity, validate alerts, and escalate confirmed incidents following established triage playbooks and SLAs.
Lead end-to-end incident investigations including evidence collection, timeline reconstruction, scope determination, root cause analysis, and preparation of actionable remediation recommendations to close security gaps and prevent recurrence.
Execute real-time containment actions (isolate endpoints, block malicious IPs/domains, revoke compromised credentials, quarantine mailboxes) in coordination with IT operations to minimize business impact and limit threat propagation.
Create, tune, and maintain detection content and alert rules for SIEM (e.g., Splunk, QRadar, Microsoft Sentinel, Elastic) and EDR platforms (e.g., CrowdStrike, Carbon Black, Microsoft Defender) to reduce false positives and increase mean time to detect (MTTD) effectiveness.
Perform advanced threat hunting using telemetry, threat intelligence, and TTP mapping (MITRE ATT&CK) to surface hidden compromises and proactively mitigate emerging attack patterns before they escalate into incidents.
Conduct host, network, and cloud forensics (Windows, Linux, container/VM images, AWS/Azure/GCP logs) to identify indicators of compromise (IOCs), attacker techniques, and persistence mechanisms, and document findings for remediation and legal hold when necessary.
Coordinate cross-functional incident responses with legal, privacy, executive leadership, engineering, and communications teams to ensure synchronized containment, regulatory compliance, and clear external/internal reporting.
Manage vulnerability triage by validating exploitability, prioritizing remediation efforts, and integrating vulnerability scanning outputs (Nessus, Qualys, Rapid7) into incident workflows and patching cadence.
Integrate and operationalize threat intelligence (commercial, open-source, internal feeds) into detection pipelines and enrichment processes to accelerate detection and investigation workflows.
Design, maintain, and execute playbooks and runbooks for common incident types (ransomware, phishing, account takeover, data exfiltration, supply-chain compromise) and continuously refine procedures based on lessons learned.
Lead phishing simulations, analyze phishing trends, and support detection improvements across email security stacks (Proofpoint, Mimecast, Microsoft Defender for Office 365) to reduce user compromise rates and improve awareness.
Support identity and access monitoring by investigating anomalous authentication activity, privileged account misuse, and suspicious service principle behavior in on-prem and cloud identity providers (Active Directory, Azure AD, Okta).
Perform log analysis and enrichment using scripting (Python, PowerShell, Bash) and automation tools to accelerate investigative tasks and reduce manual toil while preserving chain-of-custody for sensitive evidence.
Maintain and enhance endpoint protection and EDR posture through policy tuning, deployment validation, telemetry health checks, and coordination with desktop engineering to ensure full coverage and resilience.
Participate in tabletop exercises, red/blue team engagements, and post-incident reviews to surface process improvements, maturity gaps, and training opportunities across the organization.
Provide escalation-level support for Tier 1 SOC analysts, triage complex alerts, mentor junior staff, and document investigative techniques to build institutional knowledge and improve SOC throughput.
Evaluate and onboard security tools and integrations (SOAR, threat intel platforms, network sensors) by conducting proof-of-concepts, performance assessments, and vendor comparisons to improve detection and response capabilities.
Track incident metrics and KPIs (MTTR, MTTD, incident volume, containment time) and produce clear executive and technical summaries to guide strategic investments and operational improvements.
Support compliance and audit requirements by compiling incident evidence, retention documentation, control test outputs, and remediation status to satisfy regulatory frameworks (PCI-DSS, SOC 2, ISO 27001, GDPR).
Drive continuous improvement by analyzing near-misses and false positives, proposing detection logic changes, and collaborating with engineering teams to remediate systemic security weaknesses.
Maintain awareness of emerging threats and vulnerability disclosures, assess organizational exposure, and propose compensating controls or mitigations to leadership to reduce risk exposure.

Secondary Functions

Provide forensic artifacts, timelines, and written incident narratives for legal, insurance, or regulatory response and assist with evidence preservation when escalated to law enforcement.
Support ad-hoc security data requests, reporting, and exploratory analysis using log stores, SIEM queries, and data pipelines to answer investigative and compliance questions.
Contribute to the organization's security strategy, detection roadmap, and technology backlog by recommending prioritized initiatives, automation opportunities, and architectural changes.
Collaborate with application and platform teams to translate detection and containment requirements into engineering tasks, secure-by-design feedback, and instrumentation requirements for future observability.
Participate in sprint planning and agile ceremonies within the security engineering or SOC uplift team to ensure deliverables align with detection/response priorities and SLAs.
Build and maintain incident response kits, runbooks, and playbooks for high-risk business-critical applications and cloud services to accelerate response times during major incidents.
Conduct security awareness briefings, create tailored training content, and deliver feedback loops to reduce risky user behavior and improve organizational resilience.
Maintain vendor relationships for managed detection services, threat intel providers, and forensics partners, including escalations, contract renewals, and performance reviews.
Assist in scoping and performing tabletop exercises and simulated incidents to validate detection, response, and communication processes across stakeholders.
Help maintain asset inventories, critical system mappings, and business impact analyses that support accurate prioritization during incident triage and remediation planning.
