The work is sequenced in 10 stages. It starts with Defining Resilience Objectives within ISMS Frameworks, moves through Risk Assessment Specific to System Availability and Designing Redundant Architectures under ISO 27001 Controls, and ends at Governance of Resilience in Hybrid and Cloud Environments. Each stage carries its own topic list, so the sequence is followed rather than summarised.

What is in Module 1 of the System Resilience in ISO 27001 course?

Module 1 is Defining Resilience Objectives within ISMS Frameworks. It works through determine which business processes require high-availability design based on RTO and RPO agreements with stakeholders., select appropriate ISO 27001 controls (e.g., A.17.1.2, A.17.2.1) to align with resilience requirements for critical systems., negotiate acceptable levels of downtime with business unit leaders to inform recovery strategy thresholds. and 5 more.

How is the System Resilience in ISO 27001 course delivered?

The System Resilience in ISO 27001 course is fully self-paced with immediate online access after enrolment. Access does not expire and future updates are included at no cost. It can be taken on any device, and a certificate of completion is issued by The Art of Service when you finish.

How much does the System Resilience in ISO 27001 course cost?

The System Resilience in ISO 27001 course is $347 as a one time payment. There is no subscription, no per seat licence and no hidden fee. Enrolment carries a 30 day satisfied or refunded guarantee, so it can be assessed in full before you commit.

This curriculum spans the design, integration, and governance of system resilience across ISMS and business continuity functions, comparable to a multi-phase advisory engagement addressing availability risks in hybrid environments.

Module 1: Defining Resilience Objectives within ISMS Frameworks

Determine which business processes require high-availability design based on RTO and RPO agreements with stakeholders.
Select appropriate ISO 27001 controls (e.g., A.17.1.2, A.17.2.1) to align with resilience requirements for critical systems.
Negotiate acceptable levels of downtime with business unit leaders to inform recovery strategy thresholds.
Map regulatory obligations (e.g., GDPR, SOX) to resilience control implementation priorities.
Decide whether to treat resilience as a separate policy or integrate it into existing ISMS documentation.
Assess dependencies between third-party providers and internal systems when setting resilience targets.
Establish criteria for classifying information assets by resilience impact (e.g., mission-critical vs. non-essential).
Define ownership of resilience outcomes across IT, security, and business continuity functions.

Module 2: Risk Assessment Specific to System Availability

Identify single points of failure in network architecture that could compromise system availability.
Conduct threat modeling exercises focused on denial-of-service, ransomware, and infrastructure sabotage.
Quantify financial and operational impact of extended outages using historical incident data.
Adjust risk treatment plans when third-party cloud providers do not meet internal resilience standards.
Integrate availability risk into the organization’s overall risk register with consistent scoring criteria.
Validate assumptions about backup site readiness during regional disasters through scenario testing.
Document residual risks related to legacy systems that cannot support modern failover mechanisms.
Balance investment in redundancy against the likelihood of catastrophic events in the operating region.

Module 3: Designing Redundant Architectures under ISO 27001 Controls

Select active-passive vs. active-active configurations based on cost, complexity, and recovery time requirements.
Implement A.12.1.4 logging mechanisms across redundant systems to ensure audit continuity during failover.
Configure DNS failover mechanisms with TTL settings that support rapid redirection without cache issues.
Deploy load balancers with health checks that trigger automatic rerouting upon node failure.
Ensure database replication methods (synchronous vs. asynchronous) meet defined RPOs.
Isolate backup networks from primary infrastructure to prevent cascading failures.
Validate that redundant systems are geographically dispersed to avoid regional threats.
Enforce consistent patching and configuration management across all redundant nodes.

Module 4: Business Continuity Integration with ISMS

Align BCP activation thresholds with ISO 27001 incident management procedures (A.16.1.5).
Assign roles in the incident response team that reflect both ISMS and BCP responsibilities.
Conduct joint tabletop exercises involving security, operations, and business continuity staff.
Ensure BCP documentation is stored in a separate, access-controlled repository with offline copies.
Update communication trees to include external stakeholders such as regulators and customers.
Integrate backup site readiness checks into regular ISMS internal audit cycles.
Define escalation paths when BCP execution conflicts with ongoing incident containment efforts.
Review insurance policies for cyber and business interruption to validate coverage assumptions.

Module 5: Secure Backup and Recovery Operations

Enforce encryption of backup media at rest and in transit using FIPS-validated modules.
Implement immutable backup storage to prevent tampering during ransomware attacks.
Test recovery of encrypted backups using documented key escrow procedures.
Rotate backup media offsite using bonded couriers with chain-of-custody documentation.
Validate backup integrity through regular checksum verification and spot restoration.
Apply least-privilege access controls to backup management consoles and APIs.

Enforce retention periods based on legal hold requirements and storage cost constraints.

Module 6: Third-Party Resilience Assurance

Require cloud providers to produce SOC 2 Type II reports with specific focus on availability controls.
Negotiate SLAs that include financial penalties for failure to meet uptime commitments.
Conduct on-site audits of data centers when contracts permit physical inspection rights.
Map vendor incident response timelines to internal escalation procedures.
Validate that subcontractors used by third parties are included in resilience obligations.

Deploy synthetic transaction monitoring to simulate user activity and detect silent failures.
Integrate network performance monitoring with IT service management tools for rapid triage.
