Security Operations Centers (SOCs) can be categorized in several ways based on their operational focus, how they are deployed and staffed, and their organizational structure.
Here are the primary ways to classify Security Operations Center (SOC) types:
1. By Operational Focus
This classification is based on the primary mission and goals of the SOC.
Threat-Centric SOC: Focuses proactively on seeking out threats and malicious activity on the network.
They heavily leverage threat intelligence, stay updated on vulnerabilities, and establish a baseline of normal network behavior to easily identify anomalies. Compliance-Based SOC: Primarily focuses on ensuring the organization adheres to regulatory standards and policies (e.g., GDPR, HIPAA, PCI DSS).
Their operations revolve around comparing organizational posture to regulations and generating reports for audits. Operational-Based SOC: Concentrates on maintaining the security posture of internal business operations.
Their focus often includes identity and access management and maintaining rules for security technologies like firewalls and Intrusion Detection Systems (IDS).
2. By Deployment and Staffing Model
This is one of the most common ways to classify SOCs, focusing on who operates them and from where.
Internal (In-House) SOC: The organization builds, owns, and operates its own SOC.
It is staffed by regular employees. This offers maximum control and alignment with company culture but is expensive and difficult to staff and maintain round-the-clock. Managed SOC (Outsourced SOC / SOC-as-a-Service):
An organization contracts with a third-party provider (typically a Managed Security Service Provider, or MSSP) to handle all or most of its SOC functions. The provider offers 24/7 monitoring with their own staff and technology, which is faster and often more cost-effective but involves sharing data and trusting a vendor. Hybrid (Co-Managed) SOC: A combination of in-house staff and an external service provider.
For instance, an internal team might handle strategic analysis and incident response during business hours, while the outsourced partner provides 24/7 monitoring and triage. Virtual SOC (vSOC): An outsourced, cloud-based service model where a remote team of experts monitors the organization's environment without a physical facility.
The focus is on leveraging decentralized, remote teams for resilience and access to a broader talent pool.
3. By Organizational and Geographic Structure
This category deals with how SOC resources are arranged within an organization and across locations.
Centralized SOC: All security operations and resources are consolidated into a single authority and often a physical location.
This is one of the most common models and promotes streamlined management. Distributed SOC: Resources are decentralized and spread across various parts of the organization or different physical locations.
This can improve resilience and response times and leverage localized knowledge. Federated SOC: Composed of multiple semi-autonomous SOCs that operate independently but coordinate closely and share some security policies.
This balances unit independence with unified standards and is common in diverse, large organizations. Coordinating SOC: A dedicated group that oversees and coordinates the activities of other SOCs within a larger organization.
Hierarchical SOC: Structured in tiers of capability and authority, common within very large enterprises.
National SOC: A center that coordinates cybersecurity efforts at a national level, often for critical infrastructure or government agencies.
4. By Service Delivery and Operating Hours
Command SOC: A physical center with advanced visual displays and tools, used to centrally manage operations.
Ideal for large enterprises with complex needs. 24/7 SOC: Provides continuous, round-the-clock monitoring and response capabilities.
Follow-the-Sun SOC: Utilizes multiple SOCs in different time zones around the world to ensure continuous coverage, with the monitoring responsibility passing to the next active team at the end of a shift.
This optimizes workload and response for global organizations.
