Cybersecurity Incident Response in SOC for Cybersecurity

This curriculum spans the design and execution of a full cybersecurity incident response lifecycle within a Security Operations Center, comparable to multi-phase advisory engagements that integrate technical tooling, cross-functional coordination, and continuous improvement processes across global enterprise environments.

Module 1: Establishing the SOC Foundation and Operational Model

• Selecting between centralized, decentralized, or hybrid SOC staffing models based on organizational footprint and threat landscape.
• Defining shift coverage requirements to ensure 24/7 monitoring, including handover protocols between regional teams.
• Integrating the SOC with existing ITIL-based incident management workflows without duplicating ticketing efforts.
• Establishing clear escalation paths between Tier 1 analysts, Tier 2/3 responders, and executive stakeholders.
• Implementing secure, role-based access controls for SOC analysts on SIEM, EDR, and network monitoring tools.
• Documenting and version-controlling standard operating procedures for common detection and response activities.

Module 2: Threat Detection Architecture and Tool Integration

• Configuring log forwarding from firewalls, endpoints, and cloud workloads to ensure normalized ingestion in the SIEM.
• Designing correlation rules that reduce false positives while maintaining detection sensitivity for lateral movement.
• Integrating EDR telemetry with the SIEM to enable automated triage and response workflows.
• Deploying network detection and response (NDR) sensors at key network segmentation boundaries for east-west visibility.
• Validating API connectivity and authentication between SOAR platforms and identity providers for automated user lockouts.
• Assessing the performance impact of full packet capture on network infrastructure and determining retention thresholds.

Module 3: Incident Triage, Classification, and Prioritization

• Applying the MITRE ATT&CK framework to map observed behaviors and prioritize incidents by adversary tactic.
• Implementing a risk-based scoring model that factors in asset criticality, exploit availability, and data exposure.
• Distinguishing between benign anomalies and malicious activity in cloud access logs using behavioral baselines.
• Standardizing incident classification codes to ensure consistency across analyst teams and reporting systems.
• Validating alert context by enriching with threat intelligence feeds without introducing latency in triage.
• Managing alert fatigue by tuning detection thresholds and establishing suppression rules for known false positives.

Module 4: Containment and Eradication Procedures

• Executing network-level containment by reconfiguring firewall rules to isolate compromised subnets.
• Disabling compromised user accounts through automated scripts while preserving audit trail integrity.
• Removing persistence mechanisms such as scheduled tasks, registry run keys, or malicious cloud IAM roles.
• Coordinating endpoint isolation across multiple EDR platforms in a heterogeneous environment.
• Preserving volatile memory and disk images from affected systems before initiating remediation.
• Assessing the impact of containment actions on business operations and obtaining approvals for disruptive measures.

Module 5: Forensic Investigation and Evidence Handling

• Creating forensic images of physical and virtual machines using write-blockers and verified hashing methods.
• Extracting and analyzing Windows event logs for signs of credential dumping or pass-the-hash activity.
• Reconstructing attacker command sequences from PowerShell transcript logs or bash history files.
• Handling cloud-native evidence such as AWS CloudTrail logs or Azure Activity Logs with chain-of-custody documentation.
• Using memory analysis tools like Volatility to detect hidden processes or injected code in RAM dumps.
• Storing forensic artifacts in encrypted, access-controlled repositories with audit logging enabled.

Module 6: Cross-Functional Coordination and Stakeholder Communication

• Initiating communication with legal counsel when personal data or regulated information is involved in a breach.
• Coordinating with public relations to align external messaging with investigation status and legal constraints.
• Providing technical briefings to executives using non-technical summaries of impact and recovery progress.
• Engaging third-party forensic firms under NDAs while maintaining oversight of investigation scope.
• Reporting incidents to regulatory bodies within mandated timeframes, such as 72 hours under GDPR.
• Facilitating tabletop exercises with IT, legal, and business units to validate incident response coordination.

Module 7: Post-Incident Review and Continuous Improvement

• Conducting blameless post-mortems to identify process gaps, tool limitations, or detection blind spots.
• Updating detection rules and playbooks based on attacker techniques observed during recent incidents.
• Measuring mean time to detect (MTTD) and mean time to respond (MTTR) across incident types for performance tracking.
• Revising asset criticality rankings based on actual breach impact to improve future prioritization.
• Implementing compensating controls for vulnerabilities that cannot be immediately patched.
• Archiving incident data in compliance with data retention policies while enabling future threat hunting queries.

Module 8: Threat Hunting and Proactive Detection Engineering

• Developing custom detection queries to identify living-off-the-land binaries (LOLBins) in process execution logs.
• Using Sigma rules to standardize detection logic across multiple SIEM platforms.
• Conducting hypothesis-driven hunts based on threat intelligence about emerging adversary campaigns.
• Automating repetitive data collection tasks using Python scripts to query endpoints at scale.
• Validating detection efficacy through red team engagements and purple team exercises.
• Integrating threat actor TTPs into the SOC’s detection roadmap to close known coverage gaps.
