This curriculum spans the full lifecycle of malicious code management within ISO 27001, equivalent in depth to a multi-phase internal capability build covering risk assessment, policy design, technical implementation, and audit validation across complex, distributed environments.
Module 1: Defining Malicious Code Scope within ISO 27001 Context
- Determine which systems (e.g., OT, cloud workloads, endpoints) are explicitly included or excluded from the malicious code control based on asset classification.
- Map malicious code risks to specific business units and data types to justify control applicability during stage 1 certification audits.
- Decide whether containerized environments require separate malicious code detection strategies compared to traditional VMs.
- Assess if shadow IT systems discovered during asset inventory should be retrofitted with malicious code controls or decommissioned.
- Document exceptions for systems that cannot support anti-malware agents due to performance or compatibility constraints.
- Align malicious code definitions with internal incident response playbooks to ensure consistent classification during triage.
- Negotiate control boundaries with third-party service providers where endpoint protection is outside organizational control.
- Update the Statement of Applicability (SoA) to reflect justifications for partial or full implementation of A.12.2.1 controls.
Module 2: Risk Assessment Integration for Malware Threats
- Integrate threat intelligence feeds into the risk assessment process to quantify likelihood of ransomware attacks on internet-facing systems.
- Assign ownership of malware-related risks to system custodians rather than generic IT roles to ensure accountability.
- Adjust risk ratings dynamically when new malware campaigns (e.g., Emotet resurgence) are detected in the sector.
- Use historical incident data to calibrate risk models instead of relying solely on vendor-provided threat likelihood tables.
- Include supply chain compromise scenarios in risk assessments when third-party software is integrated into core systems.
- Validate risk treatment plans by requiring technical controls (e.g., EDR deployment) to be in place before risks are formally accepted.
- Document risk acceptance decisions for systems running unsupported operating systems with known malware vulnerabilities.
- Ensure malware risk scenarios are reviewed quarterly during management review meetings with documented outcomes.
Module 3: Policy Development and Control Specification
- Define acceptable configurations for real-time scanning (e.g., CPU thresholds, scan exclusions) to prevent operational disruption.
- Specify file types and extensions subject to mandatory scanning at email gateways and web proxies.
- Establish rules for handling encrypted archives suspected of containing malicious payloads.
- Prohibit local administrator rights on endpoints as a complementary control to reduce malware execution success.
- Mandate digital signing and hashing verification for all internally distributed executables.
- Define response time requirements for malware signature and behavioral rule updates across global sites.
- Require sandboxing for all executable files downloaded from untrusted domains, including SaaS platforms.
- Prohibit the use of personal USB storage devices on corporate systems through enforceable policy language.
Module 4: Anti-Malware Technology Selection and Architecture
- Evaluate EDR vs. traditional AV based on organizational detection capabilities, staffing, and SOC maturity.
- Design agent deployment sequencing to avoid network congestion during initial rollout across 10,000+ endpoints.
- Select centralized management platforms that support API integration with SIEM and ticketing systems.
- Implement failover mechanisms for on-premise update servers to maintain protection during WAN outages.
- Configure cloud workload protection platforms (CWPP) to scan container images at CI/CD pipeline stages.
- Enforce mutual TLS between anti-malware agents and management servers to prevent command-and-control spoofing.
- Define data retention policies for endpoint telemetry to balance forensic needs with privacy regulations.
- Conduct side-by-side testing of signature-based and behavior-based detection efficacy using controlled malware samples.
Module 5: Secure Configuration and Hardening Practices
- Disable AutoRun and AutoPlay features across all Windows endpoints to prevent USB-based malware propagation.
- Implement application allowlisting on critical servers where malware risk outweighs operational flexibility.
- Configure email gateways to strip or block executable file types in inbound attachments from external senders.
- Set registry and file system permissions to prevent unauthorized modification of anti-malware services.
- Enforce macro security policies in Office applications to block unsigned or untrusted VBA scripts.
- Disable PowerShell remoting on workstations unless explicitly required and logged for audit.
- Implement host-based firewall rules to restrict outbound connections from anti-malware agent processes.
- Use group policy to enforce consistent real-time scanning settings across endpoint fleets.
Module 6: Monitoring, Detection, and Alerting
- Define correlation rules in SIEM to detect multi-stage malware attacks across endpoint, email, and network logs.
- Set thresholds for anomalous process creation chains that trigger high-priority alerts in EDR consoles.
- Integrate phishing simulation results with detection tuning to reduce false negatives on socially engineered payloads.
- Configure automated quarantine actions for endpoints exhibiting confirmed malware behavior.
- Establish baseline CPU and disk utilization patterns to identify performance degradation from scanning processes.
- Assign detection ownership to specific SOC analysts to ensure consistent alert triage and response.
- Validate detection coverage by running controlled red team exercises targeting anti-malware bypass techniques.
- Document and review false positive rates monthly to adjust detection sensitivity without compromising coverage.
Module 7: Incident Response and Containment
- Activate predefined network segmentation rules to isolate infected systems without disrupting business-critical traffic.
- Preserve memory dumps and disk images from compromised endpoints before remediation for forensic analysis.
- Coordinate with legal counsel before initiating mass endpoint scans during active ransomware incidents.
- Use hash-based indicators to search for lateral movement across systems within the same trust zone.
- Engage external incident response firms only after internal containment thresholds are exceeded.
- Document chain of custody for all evidence collected during malware investigations to support legal proceedings.
- Initiate crisis communication protocols when malware impacts customer-facing systems or data.
- Conduct post-incident tabletop exercises to validate improvements to detection and response workflows.
Module 8: Third-Party and Supply Chain Risk Management
- Require software vendors to provide SBOMs (Software Bill of Materials) for all third-party applications.
- Scan all vendor-provided updates in isolated environments before deployment to production systems.
- Include malware detection requirements in SLAs with cloud service providers hosting critical workloads.
- Conduct on-site assessments of offshore development teams to verify secure coding and build practices.
- Block unauthorized SaaS file-sharing services that increase exposure to infected document uploads.
- Enforce code signing for all internally developed applications before they are distributed to users.
- Monitor DNS and HTTP traffic for connections to known malware distribution domains used by compromised suppliers.
- Require penetration test reports from third parties demonstrating resistance to common malware delivery vectors.
Module 9: Audit, Compliance, and Continuous Improvement
- Verify through technical audit that anti-malware agents are active and communicating on 100% of defined scope systems.
- Review SoA entries for A.12.2.1 annually to confirm alignment with current threat landscape and business changes.
- Measure mean time to detect (MTTD) and mean time to respond (MTTR) for confirmed malware incidents quarterly.
- Conduct unannounced control testing by introducing benign test files to validate detection and alerting workflows.
- Compare internal audit findings with external certification auditor observations to identify control gaps.
- Update training materials for end users based on trending phishing and social engineering tactics observed.
- Track patch latency for anti-malware engine and signature updates across global regions for compliance reporting.
- Revise control objectives when organizational shifts (e.g., remote work adoption) alter malware exposure profiles.
