The Network Security Monitoring lets users greatly decrease their response time if some sort of hacker tries to intrude. There are a lot of cases where organizations don’t know they have been hacked for a while now. Such a situation could easily have been avoided.
It can also be shortened as NSM. Information security has traditionally been divided into various focus areas. Network security tends to check the activity and health of the internal system via the network by sending a signal. This signal is called a ping, and it is sent to various system ports.
Network Security Monitoring
This is based on the collection of data to perform detection and analysis. With the collection of a large amount of data and information, it makes sense that a SOC should possess the ability to generate statistical data from existing data. And the statistics can be used for detection and analysis.
Network security involved access control, virus and antivirus programs/software, application security, network analysis, types of network-related security (endpoint, web, wireless), firewalls, VPN encryption, etc.
Benefits of Network Security
It is vital in protecting client data and information, keeping shared data secure, and ensuring reliable access and network performance. This can also protect from cyber threats.
A well-designed network security solution reduces overhead expenses and safeguards organizations from losses that occur from data breaches or other security incidents.
Types of Network Security Protections
- Network Segmentation
- Access Control
- Remote Access VPN
- Zero Trust Network Access (ZTNA)
- Email Security
- Data Loss Prevention (DLP)
- Intrusion Prevention Systems (IPS)
- Hyperscale Network Security
- Cloud Network Security
And they protect against:
Incidents like worms, trojan, spyware, adware, and ransomware.

Network Traffic Analyzer
This is an application that is used to record and analyze the traffic of your network. It can break down the traffic by user, application, or even IP address. This tool lets users visualize that data flows through diagrams or tables.
How to Analyze Network Traffic
- Identify your data sources
- Determine the best way to collect from data sources
- Check on the collection restrictions
- Start a small and diverse data collection
- Determine the data collection destination
- Enable continuous monitoring
- View and search for collected data
- Set up alerts
These rules will guide you analyze your network traffic.
