Telling Compliance Front to Back - Controls

Effective Compliance with Controls: A Guide for Information Security Managers

Controls are essential in today’s dynamic business environment, where organizations face numerous challenges, including evolving regulatory requirements and emerging cyber threats. For professionals across domains such as information security, compliance, business continuity, and beyond, establishing a strong compliance framework is crucial. This framework relies on well-defined controls and control objectives, which ensure the framework is implemented effectively. If the controls are insufficient or ineffective, the entire framework might not achieve its intended purpose.

This article provides a thorough understanding of controls and control objectives, explains their role in the PDCA (Plan-Do-Check-Act) cycle, and discusses the critical importance of performance reporting in maintaining an effective compliance framework.

Understanding Controls and Control Objectives

Controls are specific mechanisms or procedures implemented within an organization's processes to mitigate risks, ensure compliance, and achieve defined objectives. They are the building blocks that help organizations maintain compliance, reduce risk, and also drive operational excellence. These controls can be administrative, technical, or physical in nature, and they are integrated into an organization's process landscape to address relevant risks.

Control Objectives, on the other hand, are high-level goals that define the intended outcomes of implementing controls within the organization. They serve two primary functions:

• structuring control sets into distinct objectives and
• ensuring the completeness of controls.

These objectives guide the implementation of controls, ensuring that each control contributes to the overarching goal, thus maintaining focus and effectiveness.

For example, a control objective might be to "Ensure secure access to sensitive company information." To achieve this objective, several controls can be implemented:

• Access Controls: Implementing role-based access restrictions to limit access to sensitive data only to those who need it.
• Multi-Factor Authentication (MFA): Enforcing MFA to add an extra layer of security to the authentication process.
• Logging and Monitoring: Regularly reviewing access logs to detect unauthorized attempts to access sensitive data.

Characteristics of Controls

Controls can have various characteristics that determine their type, functionality, and role within an organization's compliance framework. Understanding these characteristics helps in designing an effective control environment that aligns with the organization's needs. Below is a table explaining different types of controls based on several attributes:

Examples of Different Control Characteristics

• Preventive vs. Corrective: Implementing multi-factor authentication (MFA) is a preventive control, as it aims to prevent unauthorized access before it occurs. In contrast, a data restoration process is corrective because it aims to restore systems after an incident has already happened.
• Automated vs. Manual: An automated firewall rule is a technical control that operates automatically to block malicious traffic. On the other hand, manual security awareness training is an administrative control that requires human participation to educate staff on security best practices.
• Compensating Control: Suppose that a small organization cannot afford full-time monitoring of access logs. Instead, it may use a monthly review of access records as a compensating control to mitigate some of the risks associated with a lack of real-time monitoring.

The Role of Controls in the PDCA Cycle

The Plan-Do-Check-Act (PDCA) cycle is a continuous improvement model widely adopted in management systems, including compliance and information security frameworks. Controls play a pivotal role in each phase of the PDCA cycle:

1. Plan

   • During the planning phase, organizations identify (potential) risks and establish control objectives that align with organizational goals and compliance requirements. This phase involves defining the scope, setting objectives, and determining the necessary controls to mitigate identified risks.
   • Example: An organization planning to mitigate data breach risks may set a control objective to "Protect customer data from unauthorized access" and identify appropriate controls like encryption and access control policies.

2. Do

   • In the implementation phase, the defined controls are implemented within the organization’s processes. This includes assigning responsibilities, training personnel, and integrating controls into daily operations (executing them).
   • Example: The organization rolls out encryption tools to protect sensitive data and ensures all employees handling customer data are trained in using these tools effectively.

3. Check

   • The check phase involves monitoring and evaluating the effectiveness of the implemented controls. This includes regular performance reporting, audits, and assessments to ensure controls are functioning as intended. For example, in vucavoid, control performance reporting is designed to continuously monitor and verify the effectiveness of each control, maintaining a dynamic assessment of the control's impact on compliance management - following a pre-defined schedule of (expected) control executions (enough of the ad part here 🤐).
   • Example: The organization conducts quarterly reviews to verify whether data encryption controls are correctly applied and that no unauthorized access has been detected. Such monitoring can also be close to real-time by making use of application support that knows about the control schedule, assigning people to assert control effectiveness, and streamlining the monitoring process.

4. Act

   • Based on the evaluation, corrective actions are taken to address any deficiencies or areas for improvement. This may involve updating controls, revising control objectives, or enhancing training programs.
   • Example: If a review identifies gaps in the encryption process, the organization may update its encryption protocols or provide additional training to employees.

By integrating controls into the PDCA cycle, organizations can establish a systematic approach to managing compliance and information security, fostering a culture of continuous improvement. However, it is a mistake to stop after implementation and assume that the control framework will be effective on its own. Organizations need to adjust for shifting scopes, evolving environments, technological advancements, and changes in the risk and threat landscape. For example, a company that implements controls for secure remote access may find those controls insufficient as new remote work technologies emerge or as existing technologies reveal new vulnerabilities (either on their own or in conjunction with connected technologies that may change over time), requiring additional measures to address newly identified risks.

Connecting Controls to Control Objectives

The relationship between controls and control objectives is integral to an effective compliance framework. Control Objectives act as a guiding structure for multiple controls, providing context and direction. Nearly always, each control objective has multiple controls attached to achieve the overall objective. This ensures that the implementation of controls remains organized and focused on achieving the desired outcomes. However, it is also possible for individual controls to be linked to multiple control objectives, although this can complicate management and tracking of effectiveness.

For example for illustration:

• A control objective like "Ensure secure access to sensitive company information" may include multiple controls such as role-based access, multi-factor authentication (MFA), and logging and monitoring.
• Another control objective, "Ensure data integrity and confidentiality", could share controls like MFA and encryption, demonstrating how certain controls can serve multiple objectives.

While linking controls to multiple objectives can increase efficiency, it also makes performance tracking more complex and may create challenges in ensuring each objective is fully met. Management of controls is easiest — from design to effectiveness monitoring — when one control is assigned to only one control objective (control to control objective should be n : 1).

For example, consider a control objective like "Ensure accurate and timely processing of customer orders." This objective can encompass several controls:

• Order Validation: Validating customer information and order details to reduce errors.
• Dual Approval for Large Orders: Implementing dual approval for significant orders to minimize fraud risk.
• Inventory Check: Verifying inventory levels before processing orders to prevent stockouts or over-promises.
• Timely Data Entry: Ensuring that order information is entered accurately and promptly into the system.

By aligning controls with specific control objectives, organizations can ensure a structured and comprehensive approach to risk management and compliance, thereby reducing the chances of oversight.

Finding the Right Control Set for Your Organization

Determining the appropriate set of controls for your organization is a critical task that requires a thorough understanding of your organization's unique risks, compliance requirements, and operational environment. Having a consultant run this task cannot rely on a simple, unaltered set of standard controls that the consultant brings along as an ever-working toolbox. Even when using well-known industry-standard sets of controls, such as ISO 27001, NIST Cybersecurity Framework, or COBIT, these should only be seen as guidelines rather than implemented unchecked on a 1:1 basis. Controls need to be tailored to the organization's unique needs, taking into account specific risks, environments, and objectives to ensure their effectiveness. This process involves assessing risks, understanding regulatory and business requirements, and selecting controls that best address these needs. Below, we outline a comprehensive (but exemplary - there is no law on how to do this) approach to finding the right control set for your organization.

1. Risk Assessment

The first step in selecting the right control set is conducting a comprehensive risk assessment (again disclaimer: there are countless ways to do this, this is one). This involves identifying (potential) risks that could impact the organization and assessing their likelihood and impact. The goal is to determine which risks are most significant and require mitigation through specific controls.

• Identify Assets and Risks: Begin by identifying critical assets within your organization, such as customer data, intellectual property, and IT infrastructure. Once assets are identified, evaluate potential threats, such as cyberattacks, data breaches, or operational disruptions.
• Assess Likelihood and Impact: For each identified risk, assess the likelihood of its occurrence and the potential impact on the organization. This can be done using qualitative or quantitative methods. For example, a data breach involving customer information may have a high impact due to regulatory fines and reputational damage, whereas a minor system glitch may have a lower impact.
• Risk Prioritization: Based on the assessment, prioritize risks to determine which ones require immediate attention. High-impact, high-likelihood risks should be prioritized for control implementation.

Example: A financial services company may identify the risk of unauthorized access to customer financial data as a top priority. This risk is both highly likely (due to the attractiveness of financial data to attackers) and has a high impact (due to regulatory fines and loss of customer trust). This example also shows that we look at gross risk here - since controls need still to be designed and implemented, resulting in net risk eventually.

2. Understanding Regulatory and Business Requirements

After assessing risks, it is essential to understand the regulatory and business requirements that apply to your organization. These requirements will guide the selection of appropriate controls to ensure compliance. It is important to note that such requirements might necessitate controls that your organization's own risk analysis may not have identified but are still required by law, contracts, or industry standards. Therefore, understanding regulatory and business requirements is not a substitute but a complementary step to risk assessment.

Additionally, while there are mandatory clauses in ISO 27001 that must be adhered to, the implementation of non-mandatory clauses should be conducted based on a risk assessment, ensuring that they are appropriately tailored to the organization's specific context.

3. Control Selection and Control Mapping

Once risks and requirements are understood, the next step is to identify the necessary control objectives, then design the controls (guided by standard or industry frameworks), and finally tailor these controls based on the organization's specific business and technical settings. This involves selecting and mapping controls to address the identified risks and ensure compliance, effectively mitigating the risks. Below is a depiction of this multi-stage process:

• Identify Control Objectives: Determine the high-level goals needed to mitigate risks effectively.
• Design Controls: Use industry frameworks (e.g., ISO 27001, NIST, COBIT) as guidelines for designing controls that meet the identified control objectives.
• Tailor Controls: Adapt the designed controls to fit the organization's unique business processes, technological environment, and specific requirements.
• Mapping Controls to Risks: Map each control to the specific risk or requirement it addresses. This ensures that all high-priority risks are covered and that there are no gaps in the control environment.

Example: A manufacturing company may use the NIST Cybersecurity Framework to identify controls related to protecting its production systems from cyberattacks. These controls might include network segmentation, intrusion detection systems, and employee awareness training.

4. Control Validation and Testing

After selecting the appropriate controls, it is essential to validate and test them to ensure they are effective in mitigating the identified risks. This step helps confirm that controls are correctly implemented and functioning as intended.

• Control Testing: Conduct tests to validate the effectiveness of each control. This can involve penetration testing, vulnerability assessments, and simulation exercises. For example, testing the effectiveness of an access control system may involve attempting to gain unauthorized access to sensitive information.
• Control Reviews: Regularly review controls to ensure they remain relevant and effective in light of changing risks and regulatory requirements. Changes in the business environment, such as new technologies or updated regulations, may necessitate changes to the control set.

Example: A retail organization that has implemented network segmentation as a control to protect payment systems should regularly test this control to ensure that unauthorized access is not possible between segmented network areas.

5. Continuous Improvement

Finding the right control set is not a one-time activity; it requires ongoing review and improvement. As the organization's environment evolves, new risks may emerge, and existing controls may need to be updated or replaced.

• Monitor Changes in the Environment: Stay informed about changes in the threat landscape, regulatory updates, and changes in business operations that may impact the effectiveness of existing controls.
• Feedback from Performance Reporting: Use the insights from performance reporting to identify weaknesses in the control environment and make necessary adjustments. If a control is not meeting its intended objective, determine whether it should be modified, enhanced, or replaced with a more effective control.

Example: A technology company may identify that as it expands globally, new data privacy regulations in different countries necessitate the implementation of additional data protection controls, such as localization and enhanced encryption.

Performance Reporting on Controls

A crucial aspect of managing controls is performance reporting, which ensures that controls remain effective over time and adapt to changing circumstances. Performance reporting involves continuously tracking, evaluating, and documenting the performance of each control, ensuring that any weaknesses are identified and addressed promptly.

Key Components of Performance Reporting

1. Documented Reporting of Each Control Cycle

   • The first component is the documented reporting of each control cycle, providing not only the status of the control for that cycle—whether effective, not effective, or not applicable (n/a)—but also supporting evidence. This documentation helps build a comprehensive audit trail for each control throughout its entire lifecycle, ensuring transparency and accountability. Ideally, each control should have its own effectiveness indicators, making it easier to evaluate non-quantitative controls.

2. Control Performance Metrics

   • To effectively assess control performance, organizations must establish metrics that provide quantifiable insights into how well each control is functioning. Metrics might include:
     • Number of Incidents: Tracking how often a control fails (e.g., unauthorized access incidents).
     • Response Time: Measuring how quickly the control mitigates an identified risk.
     • Compliance Rate: Percentage of adherence to a specific control (e.g., how many employees comply with MFA requirements).

3. Regular Audits and Reviews

   • Regular audits help verify whether the controls are functioning as intended. Internal audits can be scheduled monthly, quarterly, or annually, depending on the criticality of the control. Reviews should include:
     • Control Effectiveness: Evaluating whether controls are effectively mitigating the risks they are designed to address.
     • Gap Analysis: Identifying areas where controls are not meeting their intended objectives and require adjustments.

4. Incident Analysis

   • Whenever an incident occurs, a thorough analysis should be performed to determine if there was a failure in the control mechanism. For instance, if sensitive data is accessed by an unauthorized party, the performance report should identify whether the breach resulted from a failure in an existing control (e.g., poor password management).

5. Continuous Improvement

   • Performance reporting is not a one-off activity; it is a continuous process that feeds into the PDCA cycle. Organizations should use insights from performance reports to make necessary adjustments to controls, enhancing their effectiveness.
   • Example: If reports show that a specific access control fails during high-volume periods, adjustments may include increasing server capacity or optimizing the authentication process.

Best Practices for Effective Performance Reporting

1. Automation: Leverage automation tools like vucavoid to streamline the process of collecting, analyzing, and reporting performance data. Automation helps in reducing manual errors and allows real-time reporting.
2. Stakeholder Involvement: Ensure that key stakeholders, such as compliance managers and department heads, are involved in reviewing performance reports. Their input is essential for making informed decisions.
3. Clear Documentation: Document all findings, including control weaknesses, recommended corrective actions, and timelines for implementing changes. This documentation is essential for audit readiness and accountability.
4. Reporting Frequency: Set a frequency for performance reporting based on the risk level associated with each control. Critical controls may require weekly performance reviews, whereas less critical controls could be reviewed quarterly.
