To resist the growing number of cyberattacks, businesses use a range of security solutions and cyber command to increase cyber defenses and prevent cybercriminals from exploiting a weakness in the company network. But typical security solutions such as firewalls, IDS/IPS, and SIEM are no longer sufficient to thwart sophisticated attacks, such as national-state actors or organized criminal gangs. Recent infringements of data reveal plainly that such measures cannot keep threatening actors away. Moreover, many blind spots suffer from traditional security solutions and most cannot function on IoT devices, which leaves an important gap for cybercriminals.
Network Detection and Response (NDR) What is it?
Network detection and cyber command is a modern security technique that analyses network data to detect suspicious actions. An NDR system regularly scans network traffic and hunting the cyber threat monitors everything that happens between all entities throughout the network (e.g. users, devices, or containers). In this way, the NDR creates an overview of regular network activity; the NDR solution will shoot an alarm to the security team when an unusual activity comes across the network to check for the suspect activity.
The security team will no longer monitor network devices individually, after putting an NDR solution on the network (which is a purely software-based solution with no additional hardware sensors for ExeonTrace). The NDR solution provides total visibility on all network-connected devices. A state-of-the-art NDR such as ExeonTrace may also travel between on-site devices and the cloud environment (including public clouds such as – Azure, AWS, and Google), IoT, and industrial control systems for full viewing of the entire digital ecosystem.
Threat detection is no longer enough:
Traditional cybersecurity solutions focus on discovering and alerting the IT team to security issues. It is up to the staff to diagnose the problem and eradicate it. But this network security strategy only works for active attackers that try to access a network. Legacy tools like firewalls and the safety of endpoints prevent bad information from entering the network but cannot do anything about harmful information that has already overrun your system. Your company must also scan for malware and hazardous players in your network.
However, finding these hazards is not enough. Finding a security violation is one thing: responding immediately and efficiently with this violation is another. Security risks can act quickly and spread therefore companies need to decrease the time between identifying and removing a danger.
Functions for Network Detection and Response (NDR):
A Sangfor NDR system combines the ability to scan threats with cyber command, automated threat response, and mitigating duties. NDR tools constantly look for suspicious and/or hazardous information in a network. If something is incorrect, it diagnoses the situation to establish exactly what the safety threat is. Based on this diagnosis, it uses automatic tasks to alleviate the problem and alerts your IT personnel at the same time. The aim of these automated tasks is to try to end the problem without a member of the IT team. This decreases the time between detecting and correcting a security issue and enables your team to deal with other key issues.
How do network detection and response work?
NDR delivers a comprehensive set of capabilities for detection, investigation, and response.
Detection: NDR systems collect data in your surroundings and utilize machine analytics to expose dangers rapidly. Multi-machine analysis methodologies, such as scenario-based modeling for known tactics, techniques, and processes (TTP) and deeper traffic metadata inspections of known compromise indicators (IoC), are part of the most efficient NDR solutions to detect threats effectively.
Research: Sangfor NDR offers your team real-time network insights and analytics and collects data from within your surroundings to add useful contextual information to streamline your research.
An NDR solution can create irrefutable network-based evidence for threat analysis, enforcement of policies, support for auditing, and legal action. NDR facilitates the hunting of threats since it enables your team to discover suspicious activities fast and simply.
Response: The top NDR solutions let you speed up and automate Sangfor security operations. This is significant because you may automate many routine steps that your team takes to respond to these threats and focus on issues of greater importance. More importantly, the reaction to these risks can be automated, minimizing the time spent. For example, without any involvement, you can deactivate an account or ban an IP address in reaction to an attack.
Why do I require network detection and response from my organization?
In safeguarding your digital infrastructure, NDR plays a key role.
- History of threats is often available in three areas: network, endpoint, and logs.
- Endpoint Detection and Response (EDR) gives a complete overview of the processes on a host and their interactions.
- Sangfor NDR gives an aerial perspective of the interactions between all network devices.
- Security teams then design SIEMs to collect event log information and relate data sources from other systems.
- Security teams using these instruments are empowered to answer a wide range of queries in the event of an accident or threat hunting.
- They can answer for instance: What did this asset or account do before the warning? After the alert, what did it do? Can we figure out when things got bad?
- NDR is the most critical of this group since its perspective provides where others cannot.
- Exploits operating on a device’s BIOS level, for example, can bypass EDR or may not display harmful activity in logs. However, their behavior is accessible through network tools as soon as they interact through the network with any other machine.
How new risks now require NDR to be used:
The reason why packet recording data is so attractive is that developing threats are intended to bypass security measures normally used to spot suspicious activities that signal a compromise or violation of the infrastructure. They include technology like network/firewall and server logs, EDR software, and classic safety tools, and intrusion prevention systems, which centralize security visibility. The problem with these detecting techniques is that assailants are increasingly able to avoid or disable such instruments. Bad actors realize that enterprise-grade systems and EDR software are enabled to log.
