**Control Frameworks** are the "blueprints." They provide a high-level, structural methodology to organize risk management and governance processes. Frameworks, such as **COBIT** (focused on enterprise IT governance) or the **NIST Cybersecurity Framework**, allow organizations to map business goals to IT processes systematically. They are generally voluntary and flexible, ensuring a holistic approach to risk.
**Standards** are the "rules." They are mandatory constraints or specifications that provide specific metrics for compliance and quality. Unlike frameworks, standards are prescriptively defined to ensure consistency and interoperability. Examples include **ISO/IEC 27001** (requirements for security management) or **PCI-DSS**. Adherence to standards is often required for legal or certification purposes.
**Control Types** describe the specific function and timing of the mitigation measures defined within those frameworks and standards:
1. **Preventative:** Measures that stop a risk event from happening (e.g., firewalls, segregation of duties).
2. **Detective:** Measures that identify an event has often occurred or is in progress (e.g., intrusion detection systems, log reviews).
3. **Corrective:** Measures that restore systems and rectify damage after an incident (e.g., backup restoration).
4. **Compensating:** Alternative controls used when a primary control is not feasible or too costly.
To summarize: Frameworks organize the approach, Standards set the required baseline, and Control Types are the specific mechanisms implemented to reduce residual risk.
Control Frameworks, Types, and Standards
What are Control Frameworks and Standards? In the context of CRISC and Information Risk Management, specific methodologies are required to ensure that risks are managed consistently and effective security measures are put in place. A Control Framework is a structured set of guidelines and best practices (such as COBIT, NIST SP 800-53, or ISO 27001) that outlines how an organization should manage risks and internal controls. Standards are mandatory requirements (often derived from frameworks) that define what must be done, while Control Types categorization mechanisms that describe when and how a control modifies a risk.
Why is it Important? Implementing control frameworks and understanding control types is critical for several reasons: 1. Consistency: They provide a common language between IT and business management to discuss risk. 2. Compliance: Many frameworks map directly to regulations (like GDPR, SOX, or HIPAA), ensuring legal obligations are met. 3. Assurance: They allow auditors to measure the organization against a known benchmark. 4. Cost-Effectiveness: They prevent 'reinventing the wheel' by utilizing proven control sets.
How it Works: Control Classifications To effectively respond to risk, a Risk Practitioner must select the right classification of control. Controls are generally classified by time (relationship to the incident) and nature.
1. Classification by Timing (The Primary Types): Preventive Controls: Designed to stop an undesirable event from occurring in the first place. These are generally the most cost-effective controls. Examples: Firewalls, biometrics, segregation of duties (SoD), encryption.
Detective Controls: Designed to identify errors, anomalies, or attacks that have already occurred or are currently occurring. Examples: Intrusion Detection Systems (IDS), log reviews, security cameras (CCTV), audits.
Corrective Controls: Designed to mitigate the impact of an event and restore systems to their normal state after an incident. Examples: Backups and restoration, incident response procedures, antivirus quarantine.
2. Other Critical Classifications: Compensating Controls: An alternative control used when the primary control is too expensive or technically infeasible to implement. It provides a similar level of defense. Directive Controls: Administrative rules designed to dictate behavior (e.g., Acceptable Use Policy).
3. Applying Search Frameworks: Organizations start by selecting a framework (e.g., COBIT for IT governance). They then perform a Gap Analysis to see where their current environment fails to meet the framework's standards. Finally, they implement a mix of preventive, detective, and corrective controls to close those gaps.
Exam Tips: Answering Questions on Control Frameworks, Types, and Standards The CRISC exam tests your ability to apply these concepts, not just define them. Use these strategies:
1. Identify the 'Time' in the Scenario: If the question asks for a control to stop a risk before it happens, look for Preventive options. If the scenario implies the attack is already inside the network, look for Detective options. If the system has crashed, look for Corrective options.
2. Compensating Controls and Cost: A common exam scenario involves a primary control (like Segregation of Duties) that cannot be implemented due to a small team size. The correct answer is almost always to implement a Compensating Control (like increased supervisory review/logging).
3. Framework Selection: If a question asks about aligning IT with business goals, think COBIT. If it asks about international information security management standards, think ISO 27001. If it asks about US Federal government standards, think NIST.
4. Administrative vs. Technical: Pay attention to whether the question asks for a 'management' solution (Policies/Standards) or a 'technical' solution (Firewalls/Encryption).
5. The Rule of Primacy: Generally, Preventive controls are preferred over detective or corrective controls because it is cheaper to stop an incident than to clean it up. However, preventive controls often interfere with usability, so a balance is required.
