In this time and world that you have lived in, security problems in business networks are at their highest point. Cybercriminals with their attack techniques are constantly evolving, as we can read every day. Unfortunately, many companies fall behind when it comes to protecting themselves. Here you will see what network detection and response (NDR) is, a technology that goes beyond traditional security tools to keep your networks safe. Read on to understand how it works and why it could be the step you need to shield your network.
Have you ever wondered if your company is really prepared to defend itself against increasingly evolved digital threats? Today I’m going to talk to you about an essential cybersecurity tool that you may not have known about: network detection and response (NDR). Here you’ll see how it works, why it’s so important, and most importantly, how it can help you strengthen your network and prevent problems before they happen. Let’s dive into this key topic that could make the difference in protecting what matters most in your company.
What is an NDR and how does it work?
Network detection and response, known as NDR, is a technology that monitors and analyzes all traffic on a network. Unlike traditional methods that only focus on known threats, NDR uses artificial intelligence and behavioral analysis to identify suspicious patterns that could be a threat. This technology does not rely on specific malware signatures, making it ideal for discovering new or unusual threats that other tools might miss.
The operation of an NDR tool is based on five key steps:
- Collects network data: An NDR solution obtains real-time information from all devices connected to the network. This includes data about traffic, who connects, and what actions they take.
- Create a behavioral baseline: Analyze typical network behavior to identify any changes that may be suspicious. It is like a “map of normality” that highlights the strange.
- Detects suspicious activity: Once in the normal pattern, the system checks the traffic for deviations, such as unauthorized access or unusual data transfers.
- Take action against possible threats: If the system detects something out of the ordinary, it sends an alert or even takes automatic measures, such as blocking dangerous traffic or isolating the suspicious device.
- Constant improvement: With each new threat it finds, the system becomes more accurate, incorporating this information into its model for future detections.
Why is NDR important in your company?
Unlike traditional tools that only detect known threats, an NDR solution is designed to address today’s landscape, where threats are becoming more sophisticated. Hackers often use advanced methods, such as identity theft or movements within the same network, which tools such as antivirus or firewalls cannot always detect. This is where NDR comes in, covering those blind spots and providing real-time surveillance.
Additionally, a good NDR solution not only detects, but also responds immediately, allowing businesses to act before the attack causes damage.
Advantages and points to consider
- Real-time detection: Stay alert to the minute to identify unusual activities.
- Complete view of the network: All devices and activities are monitored, not only incoming and outgoing traffic, but also what is happening internally.
- Automation: With NDR, many responses can be automated, stopping threats without the need for constant intervention.
Points to note: NDR tools are typically more complex and require some initial investment in equipment and staff training. Additionally, they can generate false positives, especially in very large networks or with variable traffic, requiring adjustments and revisions.
If your company is looking for advanced protection to prevent network cyberattacks, an NDR solution may be the answer. With real-time detection capability and support from artificial intelligence, this technology not only detects problems, but also responds, keeping your network safe.
