Businesses utilize a variety of security solutions and cyber command to strengthen their cyber defenses and stop hackers from taking advantage of a flaw in the firm network in order to combat the growing number of cyberattacks. However, traditional security measures like firewalls, IDS/IPS, and SIEM are no longer adequate to stop complex attacks from national-state actors or organized crime gangs. Recent data breaches make it very clear that such precautions cannot deter hostile actors. Additionally, many standard security solutions have blind spots, and the majority of them do not work on IoT devices, which provides a critical hole for thieves and does not safeguard your network. WHAT IS NETWORK DETECTION AND RESPONSE (NDR)? A contemporary security method called network detection and cyber command analyzes network data to find suspicious activity. An NDR system continuously scans network traffic, looking for cyber threats, and keeps track of all interactions among all network nodes (e.g. users, devices, or containers). The NDR solution builds a picture of typical network activity in this way and alerts the security team when anything out of the ordinary happens on the network so they can look for any suspicious behaviour.

After implementing an NDR solution on the network, the security team will stop manually monitoring each network device (which is a purely software-based solution with no additional hardware sensors for ExeonTrace). Total visibility is provided by the NDR solution for all network-connected devices. For a complete view of the entire digital ecosystem, a cutting-edge NDR like ExeonTrace can also move between on-site devices and the cloud environment (including public clouds like Azure, AWS, and Google), IoT, and industrial control systems.

RISK DETECTION IS NOT ENOUGH ANYMORE: Traditional cybersecurity solutions concentrate on identifying security risks and notifying the IT staff of them. It is the responsibility of the personnel to identify and solve the issue. However, this method of network security is only effective against active intruders that attempt to access a network. Older security measures like firewalls and endpoint security keep hazardous information from accessing the network, but they are powerless to stop it once it has already infiltrated your system. Additionally, your business needs to check your network for malicious software and risky users.

Finding these dangers is not sufficient, though. Finding a security breach is one thing; promptly and effectively dealing with this breach is quite another. Companies must shorten the time between discovering and eliminating a threat since security dangers can act swiftly and spread.

NETWORK DETECTION AND RESPONSE (NDR) FUNCTIONS: An NDR system from Sangfor combines threat scanning with cyber command, automated threat response, and mitigating responsibilities. NDR tools scan a network constantly for information that may be dangerous or suspicious. When something goes wrong, it assesses the problem to determine precisely what the safety threat is. Based on this diagnosis, it employs automated procedures to resolve the issue while simultaneously informing your IT staff about it. These automatic processes are designed to try and solve the issue without involving an IT team member. This shortens the period between discovering and fixing a security vulnerability and frees up your team to work on other crucial problems.

HOW DO NETWORK DETECTION, NETWORK PROTECTION, AND REACTION WORK? A complete set of capabilities for detection, investigation, and response are provided by NDR.

Detection: NDR systems gather information about your surroundings and use machine analytics to quickly identify threats. The most successful NDR solutions to detect threats effectively include 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).

Study: Sangfor NDR provides your team with in-the-moment network insights and analytics, and it gathers information about your surroundings to provide contextual information that will help you focus your research.

An NDR system can produce unquestionable network-based proof for threat analysis, policy enforcement, auditing support, and legal action. NDR makes it easier for your team to spot suspicious activity, which speeds up the threat hunting process.

Response: You may accelerate and automate Sangfor security processes with the best NDR solutions. This is important because you can automate many of the mundane actions your team takes to address these dangers and concentrate on topics that are more crucial. More significantly, automating the response to these hazards will cut down on the time required. For instance, you can respond to an attack by blocking an IP address or deactivating an account without getting involved.

WHY DO I NEED MY ORGANIZATION’S NETWORK DETECTION AND RESPONSE TO PROTECT YOUR NETWORK? NDR is essential to protecting your digital infrastructure.

Threat histories are frequently accessible in three places: the network, the endpoint, and the logs. A thorough breakdown of all the processes running on a host and how they interact is provided by endpoint detection and response (EDR). Sangfor NDR provides a bird’s-eye view of how every network device interacts with one another. Then, security teams create SIEMs to compile data from other systems’ data sources and event log information. These tools give security personnel the ability to respond to a wide range of questions in the case of an accident or a threat detection. For example, they can respond to the question: What was this asset or account doing before to the warning? What did it do when the alert went off? Can you tell us when things started to get bad? The most significant member of this group is NDR since it offers what other perspectives do not. For instance, exploits functioning at the BIOS level of a device may avoid EDR or fail to show destructive behavior in logs. However, once they interact with any other machine through the network, their behavior is accessible via network tools. HOW NEW RISKS REQUIRE NDR TO PROTECT YOUR USABLE NETWORK NOW: Because emerging threats aim to get beyond security measures typically used to notice unusual actions that suggest a compromise or violation of the infrastructure , packet recording data is appealing. They include modern tools like intrusion detection and prevention systems, network/firewall and server logs, EDR software, and traditional safety tools. The issue with these detection methods is that attackers are becoming more adept at dodging or disabling such devices. Criminals are aware that enterprise-level systems and EDR software can log.
