Description

This curriculum spans the full lifecycle of ransomware defense in a security operations context, comparable to the technical and procedural depth required in multi-phase incident response engagements and sustained SOC modernization programs.

Module 1: Threat Landscape and Ransomware Evolution

Selecting which ransomware families to prioritize in detection engineering based on regional attack trends and industry sector exposure.
Integrating threat intelligence feeds that provide actionable IOCs and TTPs, while filtering out noise from non-relevant campaigns.
Determining whether to track ransomware-as-a-service (RaaS) affiliates separately from core operators in threat actor profiles.
Updating detection rules when ransomware variants rapidly mutate encryption techniques or obfuscation methods.
Deciding when to escalate anomalous behavior to incident response based on deviations from known ransomware pre-attack patterns.
Assessing the risk of zero-day ransomware deployment against the cost of deploying heuristic and behavior-based detection layers.

Module 2: Architecture of a Ransomware-Resilient SOC

Designing network segmentation that limits lateral movement without disrupting business-critical applications.
Deploying EDR agents across hybrid environments while managing performance impact on legacy systems.
Integrating SIEM correlation rules with endpoint, network, and identity telemetry to detect multi-stage ransomware attacks.
Implementing write-once-read-many (WORM) storage policies for logs to prevent tampering during ransomware encryption events.
Balancing real-time alerting with alert fatigue by tuning thresholds on high-volume detection sources like file modification events.
Establishing secure, isolated communication channels for SOC analysts during an active ransomware incident to prevent disruption.

Module 3: Detection Engineering for Ransomware Indicators

Developing Sigma rules to detect suspicious PowerShell or WMI usage commonly associated with ransomware deployment.
Creating custom YARA rules to identify encrypted file headers or known ransom note templates in file shares.
Configuring network IDS signatures to flag traffic to known C2 domains used by ransomware operators.
Mapping MITRE ATT&CK techniques (e.g., T1486, T1078) to detection rules for consistent coverage across the kill chain.
Validating detection logic in staging environments before deployment to avoid production false positives.
Rotating and updating detection signatures in response to evasion tactics such as domain generation algorithms (DGAs).

Module 4: Incident Triage and Initial Response

Verifying ransomware activity by cross-referencing endpoint encryption behavior with network exfiltration logs.
Deciding whether to immediately isolate infected hosts or allow limited monitoring to trace attacker movement.
Preserving memory dumps and disk images from compromised systems before disconnecting them from the network.
Coordinating with IT operations to halt automated backup jobs that could overwrite clean restore points.
Initiating communication protocols with legal and executive teams while maintaining operational security.
Documenting attacker TTPs during triage to support threat hunting and future detection improvements.

Module 5: Containment, Eradication, and Recovery

Executing network-level blocking of attacker C2 IPs at firewalls and proxies across multiple locations.
Disabling compromised user and service accounts identified during lateral movement analysis.
Validating the integrity of backup snapshots before initiating restoration to prevent reinfection.
Rebuilding critical systems from gold images rather than restoring from backups when compromise scope is uncertain.
Monitoring for residual persistence mechanisms such as scheduled tasks or registry run keys post-eradication.
Coordinating recovery sequencing to restore interdependent systems without causing cascading failures.

Module 6: Threat Hunting for Latent Ransomware Presence

Running proactive queries for abnormal volume of file rename or extension changes across shared drives.
Searching for evidence of data staging behaviors, such as large-scale file compression prior to encryption.
Investigating anomalous logon patterns from privileged accounts during off-hours in Active Directory.
Using EDR timeline analysis to reconstruct attacker activity when endpoint logging was disabled or corrupted.
Correlating failed ransomware deployment attempts with successful ones to identify gaps in prevention controls.
Conducting memory analysis to detect in-memory payloads that bypass disk-based detection mechanisms.

Module 7: Post-Incident Review and Control Hardening

Conducting a root cause analysis to determine whether the initial access vector was phishing, RDP exposure, or unpatched software.
Updating patch management policies to reduce mean time to patch for critical vulnerabilities exploited in attacks.
Revising user access controls based on privilege misuse observed during the incident.
Enhancing email gateway filtering rules to block new phishing lures used in the campaign.
Adjusting EDR and SIEM configurations to reduce detection-to-response time for similar future events.
Documenting lessons learned in runbooks and playbooks to improve consistency across SOC shifts.

Module 8: Governance, Compliance, and Stakeholder Communication

Reporting incident details to regulators within mandated timeframes while preserving legal privilege.
Justifying investment in ransomware-specific controls to executive leadership using risk-based metrics.
Aligning ransomware response plans with organizational incident response frameworks like NIST SP 800-61.
Managing disclosure decisions when third-party vendors are impacted by the same ransomware campaign.
Conducting tabletop exercises with legal, PR, and IT teams to validate cross-functional coordination.
Ensuring audit trails from detection through recovery are preserved for forensic and compliance purposes.
