Description

This curriculum spans the equivalent depth and structure of a multi-workshop internal capability program, covering policy, risk, deployment, and integration activities comparable to those conducted during an organization’s ISO 27001-aligned malware protection initiative.

Module 1: Establishing the Role of Anti-Virus in the ISMS

Define anti-virus controls within the Statement of Applicability (SoA) based on risk assessment outcomes and ISO/IEC 27001:2022 Annex A updates.
Determine whether anti-virus is classified as a preventive or detective control in the organization’s control framework.
Select which assets require anti-virus protection based on classification levels (e.g., public, internal, confidential).
Document exceptions where anti-virus cannot be deployed (e.g., legacy systems) and justify them in risk treatment plans.
Integrate anti-virus deployment requirements into the organization’s asset management process.
Align anti-virus scope with business continuity and incident response plans to ensure consistency during breaches.
Assign ownership of anti-virus policy enforcement to a designated role (e.g., Information Security Officer).
Map anti-virus activities to control A.8.16 (Protection against malware) and related controls in Annex A.

Module 2: Policy Development and Control Objectives

Draft an anti-virus usage policy specifying mandatory deployment, update frequency, and scanning requirements.
Define acceptable configurations for real-time scanning, scheduled scans, and quarantine actions.
Specify prohibited actions such as disabling anti-virus services without authorization.
Include requirements for handling false positives and procedures to escalate to IT security teams.
Establish criteria for approving alternative solutions (e.g., host-based EDR replacing traditional AV).
Define logging requirements for anti-virus events to support audit and forensic investigations.
Set thresholds for automatic alerts based on infection severity and system impact.
Ensure policy language supports compliance with regulatory requirements such as GDPR or HIPAA.

Module 3: Risk Assessment and Control Justification

Conduct threat modeling to assess malware risks specific to organizational endpoints and servers.
Quantify potential impact of malware incidents on data confidentiality, integrity, and availability.
Justify anti-virus investment by linking control effectiveness to historical incident data.
Assess risks associated with third-party software repositories and USB device usage.
Identify high-risk user groups (e.g., finance, R&D) for enhanced protection measures.
Document residual risks after anti-virus implementation in the risk register.
Evaluate whether anti-virus alone is sufficient or must be combined with application whitelisting and sandboxing.
Review malware trends annually to validate ongoing relevance of control objectives.

Module 4: Technology Selection and Vendor Management

Compare signature-based, heuristic, and behavior-based detection capabilities across vendor offerings.
Evaluate central management console features for scalability and integration with SIEM systems.
Assess vendor update frequency and response time to zero-day threats.
Negotiate SLAs covering detection rates, false positive thresholds, and support escalation paths.
Verify vendor compliance with ISO 27001 certification and third-party audit reports.
Test deployment impact on system performance before enterprise-wide rollout.
Require vendors to provide detailed logs compatible with internal logging standards.
Establish procedures for switching vendors without creating protection gaps.

Module 5: Deployment Architecture and Scope Definition

Define protection scope to include physical, virtual, and cloud-hosted endpoints.
Segment deployment by environment (e.g., production, development, DMZ) with tailored policies.
Configure different scanning schedules based on system criticality and usage patterns.
Implement agent installation via group policy, MDM, or configuration management tools.
Ensure anti-virus agents are included in standard system build images.
Define exclusion lists for performance-critical applications with documented risk acceptance.
Validate coverage across operating systems (Windows, macOS, Linux) based on asset inventory.
Integrate deployment tracking with CMDB to maintain accurate control status reporting.

Module 6: Configuration Management and Hardening

Standardize real-time protection settings across all endpoints using centralized policy templates.
Enforce automatic definition updates with a maximum allowable delay (e.g., 2 hours).
Disable user override capabilities for anti-virus services and quarantine actions.
Configure automatic remediation actions (quarantine, delete) based on threat severity.
Set up scheduled full-system scans during off-peak hours to minimize disruption.
Apply host firewall rules to restrict anti-virus communication to approved update servers.
Encrypt anti-virus logs in transit and at rest when stored centrally.
Regularly audit configuration drift and enforce compliance through automated checks.

Module 7: Monitoring, Logging, and Incident Response Integration

Forward anti-virus event logs (infections, updates, disabled services) to SIEM platform.
Define correlation rules to detect widespread outbreaks or targeted malware campaigns.
Set up automated alerts for multiple infection events within a short timeframe.
Integrate anti-virus alerts into incident ticketing systems with predefined response workflows.
Conduct periodic log reviews to identify undetected threats or configuration issues.
Retain logs for a minimum period aligned with legal and audit requirements (e.g., 12 months).
Test incident response procedures using simulated malware outbreaks.
Include anti-virus status in dashboards for executive risk reporting.

Module 8: Maintenance, Updates, and Version Control

Establish a patch management process for anti-virus engine and agent software updates.
Test updates in a non-production environment before enterprise deployment.
Define rollback procedures in case of update-related system instability.
Track version compliance across endpoints and generate non-compliance reports.
Schedule maintenance windows for updates to avoid business disruption.
Monitor vendor advisories for end-of-life announcements and plan migration.
Validate that definition updates are delivered over secure, authenticated channels.
Document all changes to anti-virus configuration in change management system.

Module 9: Audit, Compliance, and Continuous Improvement

Include anti-virus coverage and configuration checks in internal ISMS audits.
Verify that all high-risk systems have active, up-to-date anti-virus protection.
Review exception logs to ensure unauthorized deactivation is investigated and resolved.
Measure control effectiveness using metrics such as infection rate, detection latency, and remediation time.
Conduct annual review of anti-virus policy and update based on audit findings.
Compare organizational performance against industry benchmarks for malware detection.
Use penetration testing results to assess anti-virus evasion resistance.
Update risk treatment plans if anti-virus controls are found ineffective or obsolete.

Module 10: Integration with Broader Malware Defense Strategy

Coordinate anti-virus with email filtering systems to prevent malware delivery at multiple layers.
Enforce web proxy policies to block access to known malicious domains independently of AV.
Implement application control mechanisms to prevent execution of unauthorized binaries.
Deploy endpoint detection and response (EDR) tools where anti-virus lacks behavioral analysis.
Use sandboxing for detonating suspicious files before they reach end-user systems.
Train users to recognize phishing attempts that may bypass technical controls.
Apply network segmentation to limit lateral movement post-infection.
Ensure data loss prevention (DLP) systems are aware of malware incidents for policy enforcement.
