What is Managed NDR and how does it differ from other security solutions such as SIEM or EDR?
Managed Network Detection and Response (Co-Managed NDR) is a specialized security solution that continuously monitors network traffic and detects threats in real time. While SIEM (Security Information and Event Management) mainly aims to collect and analyze security data from various sources such as logs and events, NDR focuses on monitoring all network traffic. As a result, NDR also detects threats that typically leave no trace in log files, e.g. unusual network activities or anomalies in the data flow. EDR (Endpoint Detection and Response), on the other hand, focuses on end devices and their protection. EDR systems specialize in detecting threats that take place directly on the endpoint, such as a computer or server. NDR complements these approaches by providing a holistic overview of the network and also detecting the threats that can emanate from infected devices before they reach other endpoints.
Why should a managed NDR solution be considered?
Managed NDR relieves the burden on IT teams, who are often busy with other security-related tasks and projects. Monitoring and detecting threats is not only a time-consuming but also a complex task. Managed NDR solutions provide specialized resources and analysts who can watch over the network 24/7 and respond immediately in the event of an incident. By using machine learning and behavior-based detection techniques, Managed NDR solutions can efficiently identify new, hard-to-detect threats. This helps to improve network visibility and stop threats early before they can cause damage.
What advantages does a managed NDR solution offer over a self-managed NDR?
Managed NDR services bring several benefits, including the availability of experienced security experts and comprehensive threat databases. This is particularly valuable as many companies struggle to attract and retain specialized security talent. A managed service reduces internal overhead and ensures that threats are monitored around the clock. In addition, proven security protocols and automated processes are often used, which are often lacking in self-managed environments or can only be implemented with considerable effort.
What types of threats can Managed NDR detect?
Managed NDR is designed to detect a wide range of complex threats, including Advanced Persistent Threats (APT), zero-day attacks, ransomware, insider threats and even malware hidden in encrypted data streams. These threats often evade other security solutions because they use inconspicuous ways to spread. NDR detects such threats by identifying anomalies in network traffic and analyzing unusual behavior in the data flow. By continuously monitoring the entire network, threats can be detected more quickly and defended against accordingly.
How does the Managed NDR set-up process work?
Setting up a managed NDR solution begins with a comprehensive inventory and analysis of the existing network infrastructure. As part of a baseline process, the NDR solution gets to know the “normal” behavior of the network and identifies typical network patterns. Network devices, protocols and security policies are then integrated into the NDR solution. The managed NDR provider then adapts the solution to the company’s specific requirements and security policies and implements initial detection mechanisms and warning levels. There is usually a familiarization phase in which the system is further adapted to minimize false alarms and optimize the precision of threat detection.
How does Managed NDR affect IT performance and the network?
A professional NDR solution is designed to passively monitor the network while conserving resources. Nevertheless, the use of deep packet inspection and machine learning can place increased demands on the infrastructure, especially with large amounts of data and extensive analysis. However, modern solutions are often able to carry out these processes without any significant disruption to network traffic.
What does cooperation with a managed NDR provider look like?
A managed NDR provider usually provides a dedicated team that works closely with the internal IT and security teams. This includes regular reports, threat analysis and status updates to ensure that the company’s security policies are being adhered to. In the event of a security incident, the provider will take immediate action and work with the internal team to ensure a rapid incident response and return the network to normal. A professional provider also provides detailed reports and lessons learned after incidents.
What technologies and methods does Managed NDR use for threat detection?
Managed NDR solutions rely on a combination of behavior-based analysis, machine learning and anomaly detection. Machine learning continuously analyzes network data and identifies patterns or deviations that indicate potential threats. Behaviour-based analyses help to detect unusual activities such as atypical access or unauthorized data transfers. In addition, many providers use threat intelligence feeds that contain information on current threats in order to identify and block new attack vectors at an early stage.
Is Managed NDR suitable for companies of all sizes?
Managed NDR is generally suitable for companies of all sizes, but the specific benefits depend on the individual requirements. Large companies and companies with critical security requirements benefit greatly from network visibility and advanced detection mechanisms. Medium-sized companies can also benefit from Managed NDR, especially if they are active in regulated industries or strive for a higher level of security.
How are compliance and data protection requirements met by Managed NDR?
Many managed NDR providers offer solutions that are specifically tailored to industry-specific compliance requirements. This includes features such as logging and reporting in accordance with applicable data protection guidelines (e.g. GDPR in Europe) as well as the protection and encryption of all data collected. A professional managed NDR service provider will ensure that all data is processed and stored securely and that security protocols comply with the relevant legal standards. Through regular audits and certifications, companies can ensure that Managed NDR solutions also meet and document their compliance requirements.
