ISO/IEC 27001 is a widely recognized international standard that outlines the requirements for implementing an information security management system (ISMS) in any organization. The standard is designed to help companies protect their information assets by establishing a comprehensive framework for managing and protecting sensitive information. 

Implementing an ISMS can be a complex and resource-intensive process, but partnering with a managed detection and response (MDR) service provider can help organizations meet their compliance requirements more efficiently. 

MDR providers can offer a combination of services that include Managed security information and event management (SIEM), Managed endpoint detection and response (EDR), SOC services, and Threat Intelligence. These services provide organizations with the tools and resources they need to not only meet the ISO/IEC 27001 standards but also to get a competitive advantage in the industry. 

In this blog post, we will look at how MDR services can help an organization meet some important requirements of ISO/IEC 27001:2022, providing added benefits. Such a service can help organizations increase their visibility into their security environment. It can also enhance their security posture, reduce their expenses, increase their efficiency, and receive 24/7 monitoring and support from a team of security experts. 

Control 5.7: Threat intelligence

An MDR service can provide organizations with real-time threat intelligence by monitoring the latest threat information from multiple sources. This information can be used to prioritize potential vulnerabilities and take proactive measures to mitigate risks that could lead to a breach. The threat intelligence provided by MDR services can help organizations comply with the ISO 27001 requirement to have a threat management process established. 

Control 5.25: Assessment and Decision on Information Security Events 

MDR services can provide assessments of potential security incidents and help improve a response plan. Additionally, MDR services can provide real-time monitoring of the organization’s networks and systems, allowing them to quickly respond to any potential threats. This helps organizations become more proactive in their security, as they can quickly identify any potential issues and take the necessary steps to address them. 

Control 5.26: Response to information security incidents 

Part of ISO 27001 compliance is having a plan in place to respond to any potential security incidents. In the event of an actual security incident, an MDR service can help organizations respond quickly and effectively. The MDR team can provide immediate support, including containment, and remediation, minimizing the impact of the incident and preventing further damage. 

Control 5.27: Learning from information security incidents 

ISO 27001 requires organizations to have a process for learning from any security incidents that occur. MDR services can help organizations meet this requirement by providing the necessary resources and tools needed to review and analyze any potential security incidents. Identifying measures to prevent similar incidents from occurring in the future is part of this process. 

Control 5.28: Collection of evidence 

An MDR service can collect and preserve digital evidence related to security incidents, which can be used in subsequent investigations or legal proceedings. Additionally, MDR services can provide the necessary resources and support to ensure evidence is collected and stored securely. 

Control 6.8: Information security event reporting 

An MDR service can provide detailed reports on security events, including alerts, incidents, and trends. These reports can be used to demonstrate compliance with ISO 27001 and other regulatory requirements. Additionally, MDR services can offer the necessary resources and support to ensure reports are sent securely and quickly. 

Control 8.1: User endpoint devices 

MDR services can provide a comprehensive endpoint security solution tailored to their specific needs. This includes steps to identify and contain potential threats, as well as measures to prevent them from occurring. Additionally, MDR services can offer the necessary resources and support needed to ensure endpoint devices are secure and up to date. 

Control 8.7: Protection against malware 

Organizations also need a process in place to protect themselves against potential malware threats. MDR services can help organizations meet this requirement by providing a comprehensive malware protection solution tailored to their specific needs. This includes both known threats and emerging threats that may not be detected by traditional antivirus solutions. 

Control 8.15: Logging 

An MDR service can help organizations respond to log requirements by providing detailed logs of events and security activities. This includes steps to take to identify any incidents, as well as measures to ensure the logs are accurate and up to date. Additionally, MDR services can give the necessary resources and support needed to ensure logs are securely stored and accessible. While ISO 27001 does not specifically require a SIEM solution, implementing a managed SIEM service backed by a SOC can provide many benefits for ISO 27001-compliant organizations. Some examples include improved threat detection and response, reduced complexity and costs, enhanced compliance reporting, and continuous monitoring and analysis. 

Control 8.16: Monitoring activities 

An external SOC service can help organizations meet this requirement by providing real-time monitoring of networks and systems. This includes steps taken to identify any potential threats before they cause significant harm, as well as measures to prevent them from occurring.  

Control 8.23: Web filtering 

An MDR service can provide web filtering capabilities through the EPP/EDR platform. This can block access to malicious websites and prevent users from inadvertently downloading malware. 

Conclusion 

MDR services assist organizations in meeting their ISO 27001 compliance requirements by providing comprehensive threat intelligence, 24/7 monitoring and response, advanced EDR capabilities, detailed reporting, and analysis.  

Building and maintaining an internal SOC can be costly and require significant resources. By partnering with an external SOC service, organizations have the expertise and resources of a dedicated team of safety professionals. This is without additional staff, hardware, or software. The service can provide ongoing monitoring and analysis of an organization's security posture, helping to identify potential vulnerabilities and areas for improvement.
