C2M2: The government's free model for assessing your cybersecurity protocols
Global cyber threats want access to critical infrastructure and data. Organizations are instituting the federal government’s free Cybersecurity Capability Maturity Model to protect themselves.
In essence, C2M2 helps organizations to evaluate and enhance cybersecurity to keep their valuable data from getting hijacked using easily-accessible, free toolkits and resources.
Established in 2012, the original model was dubbed ES-C2M2 and was the result of a White House initiative for the electricity subsector. The effort was led by the DOE in partnership with the U.S. Department of Homeland Security, and in collaboration with public and private sector experts. In February 2014, the DOE published the first version of the model.
The program is comprised of three key components:
- Electricity Subsector-Cybersecurity Capability Maturity Model (ES-C2M2)
- Oil and Natural Gas Subsector-Cybersecurity Capability Maturity Model (ONG-C2M2)
- Cybersecurity Capability Maturity Model (C2M2)
The current C2M2 is designed to be an easily replicable framework that measures a set of defined characteristics for strengths and vulnerabilities in any organization, regardless of its industry or size. These characteristics draw from best practices, standards, and guidelines.
How the C2M2 works
An organization that intends to rollout C2M2 typically starts the process with a day-long collaborative session to evaluate their current security measures. Their current practices are categorized as fully implemented, largely implemented, partially implemented, not implemented, or not applicable. The answers are then recorded in the C2M2 toolkit.
The model looks at 10 domains of cybersecurity in this evaluation phase:
- Risk management
- Asset, change, and configuration management
- Identity and access management
- Threat and vulnerability management
- Situational awareness
- Information sharing and communications
- Event and incident response, continuity of operations
- Supply chain and external dependencies management
- Workforce management
- Cybersecurity program management
The toolkit processes the answers and generates a detailed summary of holes and gaps. We rank the domains within the organization at a Maturity Indicator Level (MIL), from MIL0 to MIL3.
Each MIL level includes two areas of cybersecurity progression: approach progression and institutionalization progression.
Approach progression refers to the completeness, thoroughness, or level of development of an activity in a domain. Institutionalization progression describes the extent to which a practice or activity is ingrained in an organization’s operations.
The more deeply ingrained an activity, the more likely the organization will continue to perform the practice over time, under pressure, and in a consistent and reliable manner.
The MILs apply independently to each domain. For example, an organization could be operating at MIL3 in the asset, change, and configuration management domain, MIL1 in the supply chain and external dependencies management domain, and MIL0 in a third domain.
MILs are also cumulative within each domain. In the above example to earn a MIL3 in the asset, change, and configuration management domain, the organization must perform all the practices in the MIL1, MIL2, and MIL3 levels.
However, the C2M2 does not suggest every organization should attempt to achieve the highest MILs. Rather, an organization’s business objectives, cybersecurity strategy, financial capabilities, and other independent factors direct which MILs should be strategized and emphasized within the different domains.
When employed correctly, the C2M2 should help an organization:
- Effectively and consistently measure and benchmark cybersecurity capabilities.
- Prioritize actions and investments to improve cybersecurity.
- Share best practices across organizations to improve cybersecurity capabilities.
The explosive growth in organizations relying on cybersecurity to harbor their company’s data and information has necessitated the development of a standardized program for regular cyber-safety inspections. This C2M2 cybersecurity maturity model is among the best available for a free program with a formalized process.
