Network security is an often overlooked area. Many organizations do not analyze network traffic because it can be technically challenging. However, hackers and threat actors typically leverage networks for malicious purposes as a first step in many full blown attacks. Additionally, they can reside inside the network for many months or even years without detection, continuously performing reconnaissance, capturing credentials and learning how you do business. This is a critical area to monitor and secure as part of any cyber security posture improvement.
Corelight NDR (Network Detection and Response) is a comprehensive network security solution designed to provide enhanced visibility, detection, and response capabilities. It focuses on monitoring and analyzing network traffic to identify potential security threats and facilitate rapid incident response. Here are the key features and benefits of Corelight NDR:
- Deep Network Visibility: Corelight NDR offers deep network visibility by capturing and analyzing network traffic at high speeds. It provides detailed insights into network protocols, communications, and behaviors, allowing security teams to gain a comprehensive understanding of their network environment.
- Network Traffic Analysis: Corelight NDR leverages powerful network traffic analysis techniques to identify and characterize network-based threats. It can detect anomalies, malicious activities, and indicators of compromise (IOCs) by analyzing patterns, flows, and relationships within network traffic.
- Threat Detection and Alerts: The solution employs advanced threat detection mechanisms, including signature-based detection, behavioral analysis, and machine learning algorithms, to identify suspicious activities indicative of cyber threats. It generates real-time alerts when potential threats are detected, enabling security teams to respond quickly and effectively.
- Protocol Intelligence: Corelight NDR is built on Zeek (formerly known as Bro), an open-source network security monitoring framework. It provides deep protocol intelligence, allowing for the detection of known attack patterns, exploitation attempts, and abnormal protocol behavior. This enables the identification of threats that may evade traditional security controls.
- File Extraction and Analysis: Corelight NDR has the capability to extract and analyze files traversing the network. It can reconstruct and analyze network sessions, extracting files for further inspection and threat analysis. This helps in detecting and mitigating threats such as malware propagation, data exfiltration, or unauthorized file transfers.
- Incident Response and Investigation: Corelight NDR supports incident response and investigation by providing detailed network-level forensics. It offers comprehensive packet-level visibility, allowing security teams to reconstruct events and perform in-depth analysis to understand the scope and impact of security incidents.
- Integration with Security Ecosystem: Corelight NDR integrates with other security tools and platforms, such as SIEM (Security Information and Event Management) systems and threat intelligence feeds. This integration enables seamless correlation of network-level events and alerts with other security data sources, enhancing overall threat detection and response capabilities.
- Compliance and Regulatory Support: Corelight NDR helps organizations meet compliance requirements by providing detailed network visibility and security monitoring capabilities. It assists in monitoring network activities for compliance with regulations such as PCI-DSS, HIPAA, GDPR, and industry-specific standards.
- Scalability and Performance: Corelight NDR is built for high-performance network monitoring and analysis, capable of handling high-speed networks with large traffic volumes. It offers scalable deployment options to accommodate diverse network infrastructures, ensuring that organizations can effectively monitor and protect their networks as they grow.
- Threat Intelligence and Updates: Corelight NDR incorporates threat intelligence feeds and regularly receives updates to stay current with emerging threats and attack techniques. This ensures that security teams have access to the latest threat information and can proactively detect and respond to new attack vectors.
By leveraging the features and benefits of Corelight NDR, organizations can enhance their network security posture, detect and respond to network-based threats in real-time, and gain deeper insights into their network environment for proactive threat mitigation.
