NDR is a security solution that detects and responds to abnormalities on the network.Recently, it has been attracting attention as it is highly effective in improving the security of internal networks.This article explains in detail the functions, advantages and disadvantages of NDR.We will also explain NDR investigations to understand malware intrusion routes and damage status.
NDR is a security measure that detects and responds to network abnormalities in real time.
NDR is an abbreviation for "Network Detection and Response" and refers to security measures to detect abnormal behavior and threats on the network and respond quickly.We will explain the background why NDR is currently attracting attention, why it is needed, and the specific functions and effects of NDR.
Background of the need for NDR
The current situation and issues listed below are behind the need for NDR.First is the increase and sophistication of cyber-attacks.New attack methods that are created every day are difficult to detect using traditional security measures, and there is a risk that traditional methods may be slow to respond.Cyberattacks targeting network vulnerabilities are a recent trend, and NDR detects anomalies on the network, leading to early detection of such attacks.
Next is the increase in IoT devices and the progress of cloud computing.This is due to the fact that corporate network environments are becoming more complex, the use of cloud services, and the increase in the number of mobile devices.The rapid spread of telework has increased the number of opportunities for employees to access networks from home, etc., which has also led to security risks.NDR is expected to be able to handle areas that cannot be covered by conventional security systems alone, as it monitors the entire network and detects abnormalities.
NDR functions and effects
Functions included in NDR include visualizing network traffic by collecting and analyzing communication patterns, detecting and notifying unusual behavior, and analyzing threats as they occur.Comprehensive monitoring of internal network traffic allows administrators to respond in real time.
NDR generates real-time alerts and notifies security personnel when it detects abnormal traffic, such as unauthorized access or large amounts of data being sent.By quickly collecting information such as communication routes, related devices, and user information, threats that are difficult to detect with normal security measures can be discovered at an early stage, leading to the identification of attack methods and intrusion routes, making it possible to prevent various security incidents. This will enable us to respond appropriately and quickly.
Difference between NDR and EDR
EDR is a system closely related to NDR. You also need to know the functions, characteristics, and relationships between NDR and EDR.
Differences in functionality and scope of support from EDR
EDR is an abbreviation for "Endpoint Detection and Response" and is a security measure that detects and responds to abnormalities in endpoints such as devices and terminals.It is a tool that collects and analyzes events, logs, process execution information, etc. on endpoints, and is different in scope and target from NDR, which detects abnormalities in communication and traffic on the network.EDR has the same real-time performance, and can be expected to be a tool for detecting abnormalities at specific endpoints, protecting them, and responding to security incidents.

Advantages and disadvantages of introducing NDR products
We will explain the advantages and disadvantages of introducing NDR products.
Advantages of introducing NDR products
One of the benefits of introducing NDR products is "real-time threat detection."NDR detects abnormal behavior on the network in real time, and when it detects an abnormality, it immediately generates an alert and notifies security personnel.It is also possible to detect cyber-attacks and breaches early, before they occur.There are many benefits from a preventive point of view in order to minimize damage.
Another major benefit is "speeding up incident response and reducing man-hours."Since it is difficult to completely prevent cyber attacks, it is important to respond quickly when damage occurs.This reduces the amount of effort required for information system departments to respond to alerts, from detecting anomalies to analyzing detected threats, thereby contributing to a reduction in man-hours.
Disadvantages of introducing NDR products
On the other hand, one thing to keep in mind when introducing NDR products is the "increased implementation and operational costs."Compatibility range and price vary depending on the product, but installation requires considerable costs for product licenses, software updates, etc.
It is also important to note that installation and subsequent operation will require "highly specialized skills."If your company does not have personnel with specialized knowledge and experience, you will need to consider investing in training or outsourcing.
What an NDR investigation can reveal and its necessity
By investigating internal network traffic logs with NDR investigation, you can clarify the intrusion route of malware and the scope of damage.
Intrusion route for malware etc.
By analyzing communication data and packet activity in real time, we detect communications caused by malware and suspicious file transfers.Quickly identify intrusion routes by receiving alerts and investigating.This will help prevent the spread of damage within the network.
Identification of the scope of damage
By detecting vulnerabilities and security holes on the network, it becomes easier to identify the scope of damage.Detects not only unauthorized access from outside, but also internal threats from employees and related parties.You can smoothly identify the cause and the range of influence.
Respond quickly to damage caused by cyber attacks with FRONTEO's "Cyber Security Investigation Package"
Security damage continues to increase worldwide, and cyberattacks targeting network vulnerabilities are one of the trends in recent years.Information used in business is exposed to danger on a daily basis, and many companies are unable to deal with cyber-attacks.In order to protect a company from cyber attacks, it is necessary to take appropriate measures.
In order to respond appropriately to cyber-attacks, it is difficult to investigate only by in-house personnel, so it is safe to request a specialized investigation company with the latest information and track record.FRONTEO's "Cyber Security Research Package" is a package that compiles and packages the minimum amount of research required in the event of an emergency.FRONTEO, which has a wide range of experience in cybersecurity investigations, provides high-quality investigation packages necessary for initial response, and is capable of conducting investigations in response to increasingly complex cyber attacks.
The "Cybersecurity Investigation Package", which can respond to a variety of incidents, is also effective in NDR investigations.In the event of an emergency, a speedy initial investigation is required to minimize damage.By preparing in advance with experts during normal times, you will be able to resolve problems quickly and accurately.First of all, why not consult FRONTEO about the necessary preparations and measures for your company?
