Co-Managed SOC

Overview

A Co-Managed SOC (Security Operations Center) is a collaborative model where an organization partners with a managed security service provider (MSSP) or a third-party cybersecurity expert to enhance its security operations. In this model, the organization and the third party share responsibilities for monitoring, detecting, responding to, and mitigating security threats. The goal is to provide the organization with comprehensive security coverage while leveraging external expertise and technology to strengthen its defense posture. The Co-Managed SOC model blends the benefits of in-house security teams with the experience, scalability, and advanced tools of an MSSP. This partnership allows organizations to achieve 24/7 security monitoring, incident response, and threat intelligence without the need to manage the entire SOC operation internally.

Key Components of a Co-Managed SOC

1. Shared Responsibility:
• The responsibilities for monitoring, managing, and responding to security incidents are shared between the organization and the MSSP.
• In-house team responsibilities might include understanding the business context, reporting, managing internal communications, and providing contextual intelligence.
• MSSP responsibilities typically include 24/7 monitoring, threat detection, analysis, incident response, and vulnerability management.
2. Integration of Tools and Technologies:
   • The Co-Managed SOC uses a combination of both the organization’s existing security tools and those provided by the MSSP.
   • It may involve integrating the organization’s Security Information and Event Management (SIEM) systems with MSSP tools for comprehensive threat detection and response.
3. Threat Detection and Monitoring:
   • The SOC is responsible for actively monitoring networks, endpoints, servers, and cloud environments for any signs of a security breach or threat activity.
   • It combines log analysis, event correlation, and threat intelligence feeds to detect anomalous behavior, malware, or unauthorized access attempts.
4. Incident Response:
   • When a security incident is detected, the Co-Managed SOC coordinates the response efforts. This includes triaging alerts, analyzing the scope of the incident, containing the threat, and initiating remediation actions.
   • The MSSP may provide expertise on specific types of threats, such as advanced persistent threats (APTs), ransomware attacks, or insider threats, while the in-house team provides contextual knowledge and resources for handling the incident.
5. Proactive Threat Intelligence:
   • The Co-Managed SOC typically benefits from the MSSP’s threat intelligence feeds, which provide insights into emerging threats, zero-day vulnerabilities, and attack tactics.
   • Proactive threat hunting is often included to detect hidden threats before they escalate into active incidents.
6. Security Reporting and Compliance:
   • Regular security reporting and documentation of all incidents and investigations are essential, especially for organizations that must meet industry-specific compliance standards.
   • The Co-Managed SOC assists in creating reports for stakeholders and ensures compliance with regulations such as GDPR, HIPAA, and PCI DSS.
7. Vulnerability Management:
   • The Co-Managed SOC helps identify vulnerabilities in the organization’s infrastructure, ensuring regular patching and updates are applied.
   • Vulnerability scans, assessments, and prioritization of remediation efforts are typically handled in collaboration with the internal team.

Benefits of a Co-Managed SOC

1. 24/7 Security Monitoring:
   • Co-Managed SOCs provide continuous monitoring and threat detection, ensuring that organizations have round-the-clock protection without needing to manage the SOC team in-house.
   • The collaboration between internal and external teams enables a more comprehensive approach to security monitoring.
2. Cost Efficiency:
   • Maintaining an in-house SOC can be expensive due to the need for skilled security professionals, tools, and infrastructure. A Co-Managed SOC allows organizations to share the costs with the MSSP, resulting in a more affordable solution.
   • This model also reduces the financial burden of having to invest in advanced security technologies and tools.
3. Access to Advanced Threat Intelligence:
   • MSSPs bring a wealth of threat intelligence resources to the table, providing organizations with insights into the latest cyber threats, trends, and vulnerabilities.
   • The MSSP’s expertise in threat analysis, combined with the organization’s internal knowledge, enables more effective detection and mitigation of emerging threats.
4. Scalability and Flexibility:
   • The Co-Managed SOC model is highly scalable, allowing organizations to adjust security coverage as their needs change. For example, as the organization grows, it can easily expand its monitoring capabilities or adopt new technologies.
   • The flexibility of a Co-Managed SOC also allows for customization of security services to fit specific organizational requirements.
5. Expertise and Specialization:
   • MSSPs offer specialized skills and knowledge in cybersecurity, including threat intelligence, forensics, incident response, and advanced attack techniques. This expertise can significantly enhance an organization’s ability to detect and respond to sophisticated threats.
   • By partnering with an MSSP, organizations gain access to a team of security experts that might be hard to build or maintain in-house.
6. Reduced Response Times:
   • The combination of in-house and MSSP teams working together typically results in faster detection and response times to security incidents.
   • The MSSP brings in additional resources and expertise to quickly identify, assess, and mitigate threats, ensuring that incidents are handled effectively and promptly.
7. Compliance Assistance:
   • The Co-Managed SOC ensures that the organization’s security practices align with industry standards and regulatory requirements. MSSPs often have experience with various compliance frameworks (e.g., ISO 27001, NIST, GDPR), making it easier for the organization to meet compliance mandates.
8. Improved Risk Management:
   • Co-Managed SOCs help organizations improve their overall risk management practices by providing ongoing assessments, vulnerability management, and incident remediation.
   • By identifying vulnerabilities and addressing them promptly, organizations can reduce their exposure to potential attacks.

Challenges in a Co-Managed SOC Model

1. Coordination Between Teams:
   • Effective communication and collaboration between the internal security team and the MSSP are critical. Misalignment in goals, priorities, or incident handling procedures can result in delayed responses or missed threats.
   • Clear processes and workflows must be established to ensure smooth interaction and coordination.
2. Control and Ownership:
   • Some organizations may feel that by outsourcing part of their security operations, they lose control over their security posture. It’s important for organizations to establish clear boundaries for what the MSSP handles and what remains under internal control.
   • Maintaining oversight and governance over the MSSP is necessary to ensure they meet the organization’s security needs and expectations.
3. Integration with Existing Systems:
   • Integrating external tools, technologies, and platforms with the organization’s existing infrastructure can be challenging, particularly if the organization has legacy systems or a complex IT environment.
   • Proper integration and testing must be conducted to ensure smooth data sharing, event correlation, and response coordination.
4. Resource Allocation:
   • While a Co-Managed SOC provides external expertise, organizations must still allocate internal resources to manage the relationship and ensure that security priorities are met.
   • Balancing the internal team’s workload with the collaboration with the MSSP can be challenging.
