A network security monitoring system (NSM) protects digital assets and data against cyber threats. But what is network security monitoring? Simply put, it involves continuously surveilling network traffic and devices to detect potential vulnerabilities or suspicious activities that might indicate an upcoming breach.

The significance of network security monitoring becomes even more apparent when we consider the statistics related to it. The annual cost of cybercrime is projected to exceed $20 trillion by 2026. Additionally, according to Sophos’ State of Ransomware 2022 report, only a mere 4% of businesses retrieve all their stolen data after paying ransoms during ransomware attacks.

Network security monitoring ensures real-time tracking and intelligent analysis of all network data. This not only keeps networks secure but also identifies areas for improvement. To help you understand this better, we will give you a complete picture of NSM in this article.

What Is Network Security Monitoring?

Network security monitoring (NSM) is the art and science of overseeing network devices and traffic. It is used to swiftly identify potential vulnerabilities, suspicious activity, and early signs of breach attempts. Think of NSM as your watchful eye over every byte that passes through your vital networks.

By deploying automated systems armed with powerful analytics capabilities, NSM provides complete visibility into your data ecosystem in real-time. This continuous tracking ensures that no stone goes unturned when identifying threats lurking within your network.

But wait! Isn’t this similar to intrusion detection system (IDS)? Although commonly confused terms, they are not interchangeable. Rather than focusing solely on detecting breaches after they occur, as IDS does, NSM takes a proactive approach. It actively analyzes incoming traffic patterns for signs of potential attacks before they happen.

Features of Network Security Monitoring

Transitioning from traditional Intrusion Detection Systems (IDS), modern Network Security Monitoring (NSM) adopts a new paradigm to fortify information security principles. Here’s a breakdown of its key features:

  • Constant Monitoring

In network security, the belief that prevention can guarantee invulnerability is flawed. Despite multiple defense layers, your IT network remains susceptible to evolving threats like

  • zero-day exploits
  • social engineering
  • insider risks
  • organized cyberattacks

Enter Network Security Monitoring: a proactive stance that acknowledges prevention’s eventual failure. It doesn’t just guard against threats; it continuously monitors, maintaining vigilance against the dynamic landscape of cybersecurity.

  • Threat-centric Defense

Unlike traditional approaches focused on preventing cyberattacks, NSM takes a deeper dive. It focuses on understanding adversaries and identifying the ‘why’ behind cyber threats. Achieving this demands fine-grained visibility into network traffic behavior and the ability to analyze anomalies effectively. In essence, NSM shifts the spotlight from just blocking attacks to understanding their motives—a crucial step in fortifying network defenses.

  • Data Collection

Amidst the ever-expanding sea of network data, NSM employs strategic data collection. While IT teams grapple with analyzing new data for intrusion patterns, NSM takes a different route. It models system behavior in real time, utilizing advanced machine learning to continuously adapt as network behavior evolves.

This strategic approach, focusing on behavior modeling, proves more effective than drowning in endless data streams. It provides a smarter way to identify potential threats.

  • Cyclic Feedback

Intrusion Detection follows a linear process, evaluating incidents in isolation. NSM, on the other hand, operates within a continuous cyclic feedback loop. Network data is captured, AI models detect network intrusions, and this knowledge improves the data collection process, enhancing the system’s overall detection capabilities.

This circular feedback loop ensures that each step contributes to refining the entire security monitoring process. It’s a dynamic approach that leverages insights to iteratively enhance network security.

What is the Purpose of Network Security Monitoring?

How does network security monitoring fulfill its purpose of safeguarding organizations from potential threats? By carefully analyzing various elements within your network, it acts as a vigilant defender against intrusions and attacks.

Network security monitoring examines client-server communications, evaluating traffic involving user requests to servers on the network. It also delves into encrypted traffic sessions, decoding data sent through the system. Furthermore, it scrutinizes the payloads carried by network packets and ensures adherence to established rules governing data transmission (network protocols).

In addition to these individual components, network security monitoring places great emphasis on observing traffic flow between multiple endpoints. It focuses on identifying any deviations from normal patterns that may indicate nefarious intent.

Moreover, NSM captures comprehensive snapshots of your organization’s digital ecosystem in real-time that is precisely tailored toward protecting infrastructure integrity. It allows you peace of mind knowing that any malicious or suspicious activity is promptly detected.

And you will never miss out on prompt incident notification either. Timely alerts ensure quick response times should a possible breach be identified – enabling proactive mitigation actions to be swiftly taken.

What Are the Benefits of Network Security Monitoring?

When it comes to cybersecurity, depending solely on outer defenses proves futile. As Troy learned, breaches are inevitable. The longer a threat lurks within, the costlier the consequences. One cybersecurity attack unfolds every 39 seconds. Moreover, between 2020 and 2021, the average data breach cost rose nearly 10%, reaching $4.24 million.

For any organization, the key lies in swift action. A breach lasting over 200 days costs an extra $1.12 million on average. Thus, the effectiveness of a network security monitoring solution hinges on transparency. It places critical systems under a microscope, enabling the rapid detection of malicious traffic and efficient response to security incidents.

  • Minimizing Response Times

Network security monitoring cuts the time needed to locate, evaluate, and respond to security threats. Real-time tracking and automated tasks streamline the process, preventing potential damage escalation. The sooner you act, the less impact a security breach will have on your organization.

  • Improved Efficiency

Traditional network monitoring demands constant attention, draining IT teams. Modern network security monitoring tools automate tasks, allowing professionals to utilize their time more efficiently. Such automation not only enhances productivity but also reduces the likelihood of human errors that could lead to vulnerabilities.

  • Better Customer Experience

A security breach doesn’t just affect your business—it impacts the customers relying on your services. Network security monitoring ensures swift resolution of threats, maintaining a consistent and positive customer experience. It’s not just about protecting your business; it’s about safeguarding the trust your customers place in your networks.

  • More Cost Savings

Beyond protecting your network investment, effective network security monitoring translates to significant cost savings. By preventing data breaches and their associated financial losses, it safeguards your organization’s financial health. These savings become even more pronounced when considering the network improvements made possible by enhanced visibility.

How Does Network Security Monitoring Differ From Network Monitoring?

Understanding the contrast between network security monitoring and network monitoring is crucial for effective IT management. Let’s break down the key differences:

  • Network Monitoring:

    • Examines network activity for hardware malfunctions or resource overload.
    • Measures network availability, performance, and configuration.
    • Alerts via SMS or email for issues in availability, performance, or configuration.
    • Essential for network administrators to troubleshoot and correct problems.
  • Network Security Monitoring:

    • Shields the organization from potential vulnerabilities and exploits.
    • Analyzes diverse factors, including network payload and traffic patterns.
    • Aims for continuous service, checking for suspicious activities and threats.
