Description

This curriculum spans the design and operation of enterprise malware detection programs, comparable in scope to a multi-phase advisory engagement that integrates threat intelligence, detection engineering, and incident response across endpoint and network environments.

Module 1: Threat Landscape and Malware Taxonomy

Selecting malware classification criteria (e.g., behavior, delivery mechanism, persistence) based on organizational attack surface and industry threat intelligence.
Integrating MITRE ATT&CK framework mappings into malware categorization to align detection rules with observed adversary tactics.
Assessing the operational impact of polymorphic and metamorphic malware on signature-based detection systems.
Deciding when to prioritize zero-day malware analysis versus known threat variants based on current IOCs and threat feeds.
Managing false positives from legitimate software flagged as malware due to heuristic or behavioral analysis.
Documenting malware lineage and family relationships to support incident correlation and threat actor attribution.

Module 2: Endpoint Detection and Response (EDR) Architecture

Configuring EDR sensor telemetry levels to balance performance overhead with forensic data collection requirements.
Designing deployment rollouts using phased staging groups to validate detection efficacy and minimize endpoint disruption.
Implementing tamper protection mechanisms on EDR agents to prevent disablement by privileged malware.
Selecting between real-time monitoring and periodic scanning based on endpoint criticality and resource constraints.
Integrating EDR with existing endpoint protection platforms (EPP) to avoid tool redundancy and alert fatigue.
Establishing data retention policies for endpoint telemetry in compliance with legal and forensic investigation needs.

Module 3: Network-Based Malware Detection

Positioning network IDS/IPS sensors at ingress/egress points and internal segmentation zones to capture lateral movement.
Developing custom Snort or Suricata rules to detect command-and-control (C2) traffic patterns specific to prevalent malware families.
Decrypting TLS traffic for inspection while addressing privacy regulations and certificate management overhead.
Correlating DNS tunneling anomalies with endpoint process behavior to identify data exfiltration attempts.
Managing false positives from encrypted SaaS traffic that mimics C2 communication patterns.
Scaling network detection systems to handle high-throughput environments without packet loss or latency degradation.

Module 4: Static and Dynamic Malware Analysis

Configuring isolated sandbox environments with realistic OS configurations and user artifacts to trigger malware execution.
Extracting and analyzing packed payloads using automated unpacking tools while avoiding anti-analysis techniques.
Validating YARA rule accuracy against malware samples to prevent overbroad matching on benign files.
Automating file hash submission to VirusTotal and hybrid analysis platforms while managing API rate limits and data exposure.
Handling malware samples securely using cryptographic hashing and write-once media to prevent accidental execution.
Documenting behavioral artifacts (registry changes, file drops, process trees) for use in detection engineering.

Module 5: Detection Engineering and Rule Development

Writing Sigma rules that translate malware TTPs into platform-agnostic detection logic for SIEM integration.
Validating detection rules in staging environments using red team emulation to confirm trigger accuracy.
Adjusting detection thresholds for heuristic alerts to reduce noise while maintaining sensitivity to novel threats.
Version-controlling detection rules using Git to track changes and support rollback during false positive incidents.
Coordinating rule updates with threat intelligence feeds to ensure timely coverage of emerging malware campaigns.
Measuring detection coverage gaps using purple team assessments and ATT&CK coverage metrics.

Module 6: Threat Intelligence Integration

Filtering and prioritizing IOCs from open-source and commercial feeds based on relevance to industry and infrastructure.
Automating IOC ingestion into SIEM, firewall, and EDR systems using STIX/TAXII protocols with validation checks.
Assessing the reliability of threat intelligence sources based on timeliness, false positive rates, and attribution confidence.
Mapping threat actor infrastructure patterns to internal network telemetry to identify potential compromise.
Managing IOC expiration and deprecation schedules to prevent stale indicators from triggering alerts.
Sharing anonymized malware findings with ISACs while adhering to data privacy and disclosure policies.

Module 7: Incident Response and Malware Containment

Executing memory acquisition on infected systems before disk imaging to preserve volatile malware artifacts.
Isolating compromised endpoints using automated playbooks while preserving network connectivity for investigation.
Coordinating containment actions across IT operations to minimize business disruption during eradication.
Validating malware removal by cross-referencing registry, file system, and service persistence mechanisms.
Conducting post-incident root cause analysis to identify initial infection vector and control failures.
Updating detection and prevention controls based on lessons learned from malware incident timelines.

Module 8: Governance and Detection Operations

Establishing SLAs for malware detection validation, triage, and escalation within the SOC workflow.
Conducting regular detection rule reviews to retire obsolete logic and optimize query performance.
Measuring detection efficacy using metrics such as mean time to detect (MTTD) and detection coverage rate.
Aligning malware detection policies with regulatory requirements (e.g., NIST, ISO 27001, GDPR).
Managing access controls for malware analysis tools and samples to prevent insider misuse or data leakage.
Integrating malware detection KPIs into executive risk reporting for cyber resilience assessment.
