Stress Testing and Scenario Analysis Policy

1. Introduction

Purpose and Scope: This policy outlines the framework for conducting regular stress testing and scenario analysis of our ICT systems to evaluate their resilience and operational continuity under adverse conditions. This includes identifying vulnerabilities, assessing the impact of potential disruptions, and developing mitigation strategies to ensure the continued delivery of critical services in line with DORA requirements. The scope encompasses all ICT systems supporting critical functionalities, including but not limited to payment systems, data processing, communication networks, and customer-facing applications.

Relevance to DORA: This policy directly supports DORA's objectives by enhancing the resilience and security of our ICT systems. It addresses DORA's focus on operational resilience, incident reporting, and recovery capabilities. Specifically, it helps meet requirements related to identifying and managing risks, conducting regular stress tests, and having robust incident response plans.

2. Key Components

The policy includes the following key components:

  • Risk Identification and Assessment: Identifying potential threats and vulnerabilities affecting ICT systems.

  • Scenario Development: Defining realistic and plausible scenarios reflecting potential disruptions.

  • Stress Testing Methodology: Defining the approach, tools, and metrics for conducting stress tests.

  • Impact Assessment: Evaluating the potential impact of disruptions on business operations and customers.

  • Mitigation and Recovery Planning: Developing and documenting mitigation strategies and recovery plans.

  • Reporting and Communication: Establishing procedures for reporting stress test results and communicating findings.

  • Review and Update: Defining the process for regularly reviewing and updating the policy and its implementation.

3. Detailed Content

3.1 Risk Identification and Assessment:

  • In-depth Explanation: This section details the process of identifying potential threats and vulnerabilities to ICT systems. This involves analyzing internal and external factors, considering past incidents, and leveraging threat intelligence feeds.

  • Best Practices: Employ a combination of qualitative and quantitative risk assessment methods; involve subject matter experts from various departments; utilize vulnerability scanning tools; regularly review and update the risk register.

  • Example: Identifying risks such as cyberattacks (DDoS, ransomware), natural disasters (earthquake, flood), hardware failures, software bugs, and human error. Assessing the likelihood and impact of each risk using a risk matrix.

  • Common Pitfalls: Overlooking less obvious risks; failing to involve relevant stakeholders; relying solely on automated vulnerability scans without manual review.

3.2 Scenario Development:

  • In-depth Explanation: This section defines the process of developing realistic scenarios that represent potential disruptions. Scenarios should cover a range of severity and likelihood.

  • Best Practices: Utilize historical data, industry benchmarks, and expert opinions; consider both individual and cascading failures; develop scenarios with varying degrees of impact on different systems.

  • Example: Scenario 1: A major cyberattack targeting the payment processing system, leading to a prolonged outage. Scenario 2: A natural disaster causing significant damage to a data center, resulting in data loss and service interruption. Scenario 3: A widespread software bug affecting multiple critical applications.

  • Common Pitfalls: Creating unrealistic or overly simplistic scenarios; neglecting to consider dependencies between systems; failing to adequately test the scenarios.

3.3 Stress Testing Methodology:

  • In-depth Explanation: This section details the methodology for conducting stress tests, including the tools, techniques, and metrics used.

  • Best Practices: Employ a combination of simulated and real-world testing; utilize automated tools for monitoring system performance; define clear success and failure criteria; document the testing process thoroughly.

  • Example: Using load testing tools to simulate high volumes of transactions; injecting simulated failures into the system; monitoring key performance indicators (KPIs) such as response time, transaction success rate, and resource utilization.

  • Common Pitfalls: Insufficient testing scope; inadequate test data; lack of clear testing objectives; ignoring test results.

3.4 Impact Assessment:

  • In-depth Explanation: This section outlines the process for evaluating the potential impact of disruptions on business operations and customers.

  • Best Practices: Utilize business impact analysis (BIA) techniques; quantify the financial, reputational, and operational consequences of disruptions; define recovery time objectives (RTOs) and recovery point objectives (RPOs).

  • Example: Quantifying the financial losses associated with a payment system outage; assessing the reputational damage caused by a data breach; determining the time required to restore service after a disaster.

  • Common Pitfalls: Underestimating the impact of disruptions; failing to consider indirect impacts; neglecting to involve business stakeholders.

3.5 Mitigation and Recovery Planning:

  • In-depth Explanation: This section details the development and documentation of mitigation strategies and recovery plans.

  • Best Practices: Implement preventative controls to reduce the likelihood of disruptions; develop detailed recovery plans for various scenarios; regularly test and update recovery plans; establish communication protocols.

  • Example: Implementing multi-factor authentication to prevent unauthorized access; establishing a backup data center to ensure business continuity; developing a detailed incident response plan; creating communication templates for stakeholders.

  • Common Pitfalls: Lack of detailed recovery procedures; insufficiently tested recovery plans; inadequate communication protocols.

3.6 Reporting and Communication:

  • In-depth Explanation: This section outlines the process for reporting stress test results and communicating findings.

  • Best Practices: Prepare comprehensive reports summarizing stress test results; communicate findings to relevant stakeholders; track and monitor remediation efforts.

  • Example: Creating a report summarizing the results of a stress test, including identified vulnerabilities, impact assessments, and recommended mitigation strategies.

  • Common Pitfalls: Delayed or inadequate reporting; unclear communication; failing to track remediation efforts.

3.7 Review and Update:

  • In-depth Explanation: This section defines the process for regularly reviewing and updating the policy and its implementation.

  • Best Practices: Review the policy annually or more frequently if significant changes occur; conduct regular stress tests; update the policy based on lessons learned.

  • Example: Reviewing the policy annually, updating scenarios based on emerging threats, and incorporating feedback from stress tests.

  • Common Pitfalls: Failing to regularly review and update the policy; neglecting to incorporate lessons learned.

4. Implementation Guidelines

  • Step-by-step process:

1. Establish a stress testing team with representatives from IT, business units, and risk management.

2. Identify and assess critical ICT systems and potential threats.

3. Develop realistic scenarios based on risk assessments.

4. Define stress testing methodologies and metrics.

5. Conduct stress tests and assess the impact of disruptions.

6. Develop mitigation and recovery plans.

7. Report results and communicate findings to stakeholders.

8. Review and update the policy and implementation regularly.

  • Roles and Responsibilities: Clearly define roles and responsibilities for each team member, including ownership of specific tasks and deliverables.

5. Monitoring and Review

  • Effectiveness Monitoring: Track key metrics such as the number of stress tests conducted, the time taken to recover from simulated disruptions, and the number of vulnerabilities identified and remediated.

  • Frequency and Process: Review the policy and its implementation annually or more frequently as needed. The review should involve a thorough assessment of the effectiveness of the stress testing program and identification of areas for improvement. This should include a review of incident reports and post-incident analysis to identify gaps and refine scenarios and mitigation strategies.
