Description

This curriculum spans the design and operational governance of malware defenses across enterprise functions, comparable to a multi-phase advisory engagement that integrates risk management, technical controls, and compliance alignment across IT, OT, and cloud environments.

Module 1: Establishing a Malware Risk Governance Framework

Define scope boundaries for malware risk coverage across corporate, OT, and cloud environments based on asset criticality.
Select and adapt a cybersecurity framework (e.g., NIST CSF, ISO 27001) to align with organizational risk appetite and regulatory obligations.
Assign formal accountability for malware risk ownership across business units, IT, and security teams using RACI matrices.
Develop risk tolerance thresholds for malware incidents based on business impact analysis (BIA) outcomes.
Integrate malware risk into enterprise risk management (ERM) reporting cycles and board-level dashboards.
Establish criteria for when malware events escalate to incident response versus routine remediation.
Document decision logic for accepting residual malware risk after control implementation.
Conduct gap analysis between current controls and required baseline protections per industry standards.

Module 2: Threat Intelligence Integration for Malware Defense

Evaluate and subscribe to threat feeds based on relevance to sector-specific malware (e.g., financial trojans, ransomware variants).
Implement automated ingestion of STIX/TAXII threat indicators into SIEM and EDR platforms.
Filter and prioritize IOCs based on geolocation, TTPs, and historical attack patterns targeting peer organizations.
Assign analysts to validate threat intelligence relevance before deploying detection rules.
Develop playbooks for responding to emerging malware families identified in intelligence briefings.
Establish SLAs for updating firewall and email gateway blocklists upon new threat confirmation.
Coordinate with ISACs to share anonymized malware artifacts while preserving legal compliance.
Measure false positive rates from threat intelligence to refine filtering policies.

Module 3: Endpoint Detection and Response (EDR) Governance

Define EDR agent deployment priorities based on device sensitivity and user role (e.g., executives, developers).
Negotiate acceptable performance thresholds for EDR agents to avoid business disruption.
Configure EDR alert severity levels to align with SOC triage capacity and response SLAs.
Implement tamper protection policies that prevent local users from disabling EDR services.
Design quarantine workflows that balance containment speed with business continuity needs.
Standardize EDR data retention periods to meet forensic and compliance requirements.
Enforce certificate-based authentication for EDR management console access.
Conduct quarterly EDR efficacy testing using controlled malware emulation.

Module 4: Email and Web Gateway Security Controls

Configure MIME type blocking rules to prevent executable attachments in inbound email.
Implement URL rewriting and real-time scanning for hyperlinks in email messages.
Enforce strict DMARC, DKIM, and SPF policies to reduce phishing and spoofed sender attacks.
Deploy sandboxing for suspicious email attachments with delayed delivery during analysis.
Define acceptable use policies for personal webmail access from corporate devices.
Configure SSL/TLS inspection on web gateways with certificate trust management.
Block access to known malicious domains using dynamic threat intelligence feeds.
Monitor and log exceptions for users requiring access to high-risk categories (e.g., file sharing).

Module 5: Patch and Vulnerability Management Integration

Map critical vulnerabilities (e.g., CVEs) to known malware exploitation methods for prioritization.
Define patching SLAs based on exploit availability and asset exposure (internet-facing vs internal).
Coordinate with system owners to schedule out-of-cycle patches for zero-day threats.
Implement automated vulnerability scanning with credentialed access for accurate detection.
Enforce application whitelisting on high-risk systems where patching is delayed.
Track unpatched systems in a risk register with documented justification and compensating controls.
Integrate vulnerability data into EDR and SIEM correlation rules for attack chain detection.
Conduct monthly patch compliance audits with remediation tracking to closure.

Module 6: Privileged Access and Application Control

Enforce Just-In-Time (JIT) access for administrative accounts to limit malware persistence opportunities.
Implement application allowlisting on critical servers and workstations using hash or publisher rules.
Disable PowerShell and scripting engine execution for standard users via GPO or MDM.
Restrict macro execution in Office documents through centralized policy enforcement.
Monitor for privilege escalation attempts using EDR and SIEM behavioral analytics.
Integrate PAM solutions with EDR to correlate privileged session activity with malware alerts.
Conduct quarterly reviews of local admin rights assignments across endpoints.
Deploy user behavior analytics to detect anomalous file execution patterns.

Module 7: Incident Response and Malware Containment

Define malware containment procedures for different system types (e.g., domain controllers, databases).
Pre-stage forensic imaging tools and write-blockers for rapid evidence collection.
Isolate infected systems using automated VLAN reassignment or firewall rule updates.
Preserve memory dumps and disk images for reverse engineering and attribution.
Coordinate communication with legal and PR teams before public disclosure decisions.
Execute data restoration from clean backups with validation checks for reinfection.
Document root cause analysis using frameworks like MITRE ATT&CK for post-incident reporting.
Update detection signatures and rules based on lessons learned from incident artifacts.

Module 8: Third-Party and Supply Chain Malware Risk

Require software vendors to provide SBOMs (Software Bill of Materials) for critical applications.
Conduct static and dynamic analysis of third-party software before deployment.
Enforce contractual clauses requiring vendors to disclose malware incidents affecting delivered products.
Monitor vendor update channels for code signing certificate misuse or repository compromises.
Restrict USB and external media use from third-party contractors on corporate systems.
Implement network segmentation for third-party access with strict egress filtering.
Verify integrity of downloaded software using cryptographic checksums and digital signatures.
Assess cloud service providers’ malware detection capabilities during vendor due diligence.

Module 9: Metrics, Reporting, and Continuous Improvement

Track mean time to detect (MTTD) and mean time to respond (MTTR) for malware incidents.
Report on malware infection rates per business unit and device type for trend analysis.
Calculate false positive rate for EDR and email security tools to optimize tuning.
Conduct red team exercises simulating malware delivery to test detection coverage.
Review control effectiveness quarterly using audit findings and incident data.
Update malware response playbooks based on changes in threat landscape or infrastructure.
Benchmark detection capabilities against MITRE ATT&CK Evaluations or equivalent.
Adjust security investment priorities based on cost-per-incident and risk reduction ROI.

Module 10: Regulatory Compliance and Audit Readiness

Map malware controls to specific requirements in GDPR, HIPAA, PCI DSS, or SOX.
Maintain documentation of malware prevention, detection, and response controls for auditors.
Prepare evidence of regular patching, AV updates, and EDR coverage for compliance reviews.
Conduct internal audits of malware control configurations using standardized checklists.
Respond to auditor findings with remediation plans and timelines.
Retain logs and incident records for minimum statutory retention periods.
Implement data loss prevention (DLP) to prevent malware exfiltration of regulated data.
Validate encryption of sensitive data to reduce impact if malware bypasses controls.
