Find out how it can potentially reduce costs and explore steps to get started with this advanced security approach.


What is Microsegmentation in Networking & Why Is It Important?

Microsegmentation in networking refers to the practice of dividing a network into smaller, isolated segments, or microsegments, to enhance security and control network traffic. 

Unlike traditional network security measures that rely on perimeter defenses, micro-segmentation operates at a granular level within the network, allowing organizations to establish fine-grained access controls and contain potential security breaches.

In today’s digital landscape, where cyber threats are constantly evolving, micro segmentation has become increasingly important. It provides organizations with a proactive security approach that goes beyond the traditional defense-in-depth strategy. 

By implementing micro segmentation, organizations can limit the lateral movement of attackers within their network, preventing them from freely accessing sensitive data or systems. 

This approach reduces the attack surface, making it significantly harder for cybercriminals to exploit vulnerabilities and carry out successful attacks.

Micro-segmentation also plays a vital role in protecting critical assets and meeting regulatory compliance requirements. 

By segmenting the network and applying specific security policies to each segment, organizations can ensure that only authorized individuals or devices have access to sensitive data or resources. 

This level of control helps organizations maintain compliance with industry regulations, such as the General Data Protection Regulation (GDPR) or the Health Insurance Portability and Accountability Act (HIPAA).

Will Microsegmentation Reduce Costs?

Microsegmentation is not only a robust security strategy but can also have a positive impact on an organization’s cost efficiency. 

Let’s explore how microsegmentation can reduce costs while enhancing network security.

Firstly, microsegmentation improves resource utilization by enabling organizations to allocate their network resources more efficiently. 

By segmenting the network, organizations can allocate specific resources, such as bandwidth, processing power, and storage, to each segment based on its unique requirements. 

This targeted resource allocation ensures that resources are not wasted on unnecessary or unused segments, leading to cost savings.

Additionally, microsegmentation minimizes the risk of a security breach or data breach, which can result in substantial financial losses. 

By implementing granular access controls and isolating sensitive data or critical systems, organizations reduce the potential impact and cost of a breach. 

The containment provided by microsegmentation restricts lateral movement and limits an attacker’s ability to move freely within the network, minimizing the potential damage caused by a successful breach.

Furthermore, microsegmentation helps organizations achieve compliance with regulatory standards. Non-compliance can lead to severe financial penalties, legal consequences, and damage to an organization’s reputation. 

By implementing microsegmentation and enforcing specific security policies for each segment, organizations can meet the regulatory requirements relevant to their industry. Compliance with these standards avoids costly penalties and ensures that the organization maintains a positive reputation.

While microsegmentation itself may involve upfront costs, such as implementing the necessary infrastructure and deploying appropriate security solutions, the long-term cost savings and risk reduction outweigh the initial investment. 

The proactive nature of microsegmentation helps organizations avoid the substantial costs associated with remediation, legal fees, loss of customer trust, and potential fines resulting from a security breach.

The need for network security monitoring (NSM) has become paramount to ensure the proper functioning of worldwide networks. 

NSM is an essential part of any organization’s security strategy, as it provides real-time monitoring of the network to identify and prevent security breaches. 

In this article, we will explore what is Network Security Monitoring (NSM), how It works and the top nine NSM tools available in 2023 to help organizations secure their networks.


What is Network Security Monitoring (NSM) & How Does It Work

Network Security Monitoring (NSM) is the practice of regularly reviewing an organization’s system to detect any unauthorized access or intrusions in the IT network. 

NSM aims to identify, correlate, and characterize networking activities that can be classified as intentional unauthorized activities. 

It involves collecting and analyzing data, which in turn allows companies to detect and respond to intruders in their network before they cause significant damage. 

NSM verifies the effectiveness of the first lines of defense, provides the opportunity to remediate threats before they cause harm, and enables organizations to understand where the holes are in their system and how to fix them.

NSM is not a way to prevent intrusions themselves; instead, it is based on the idea that prevention may fail, and detection and response become necessary. NSM complements other security tools and systems such as firewalls, antivirus, and intrusion prevention systems by providing visibility in the network. 

NSM does not block, filter, or deny any traffic, and its role is to detect intruders who bypass the prevention measures. Unlike legacy networks that rely upon individual firewalls and access management systems, next-generation NSM adds software-defined perimeter defenses that cover physical and virtual devices. 

Automation tools also handle software updates, user activity, and policy management. Network management tools control network security from a single interface, providing complete visibility at all times.

In summary, NSM is a modern paradigm for organizational security that involves collecting and analyzing data to detect and respond to intruders in the network before they cause significant damage. 

NSM complements other security tools and systems and provides complete visibility of the network infrastructure.


Differences Between Network Security Monitoring vs. Network Monitoring 

Network monitoring and network security monitoring are two different functions that provide distinct purposes within an organization. 

Network monitoring involves monitoring and tracking network activity for problems or issues caused by malfunctioning devices or overloaded resources, while network security monitoring analyzes a variety of complex factors to detect and respond to known malicious activities, vulnerabilities, and exploits in the wild.

Network monitoring tools use measurements and algorithms to set a baseline on data-at-rest and measure three primary metrics, including availability, performance, and configuration. 

Meanwhile, network security monitoring tools analyze network payload, protocols, client-server communications, encrypted traffic sessions, traffic patterns, and traffic flow to detect and alert administrators to any suspicious or malicious activities to contain a threat.

While both types of monitoring use some overlapping tools, they must work together to provide comprehensive analytics. Network monitoring tools provide a high-level view of the infrastructure, while network security monitoring tools protect businesses from potential vulnerabilities and attacks. 

The effectiveness of security monitoring can be reduced by using the same tools for both network monitoring and security monitoring, leaving an environment vulnerable to advanced attacks.
