Network detection and response are essential for any digital organization. As organizations become increasingly complex, networks, devices, and the need to monitor and stop potential threats become more complex. With an increase in complex networks and devices, potential attackers are looking for better ways to gain access to an organization and its data.
An NDR can help security teams detect, identify, and respond to malware and attempted attacks on user networks and devices. These devices, whether on-premises, in the cloud, or in hybrid environments, will all benefit from having an NDR in place.
Although they cannot prevent suspicious traffic, network detection and response solutions detect, track and eliminate risks for organizations of all sizes.
Why Network Detection and Response Matters
Increase in security incidents
The number of security incidents has increased over the past few years. These dizzying increases in attacks have created the need for better and faster security software. And not just for large companies. While most attackers focus on large companies with big pockets, small and medium-sized enterprises (SMEs) are targeted 43% of the time. Indeed, attackers have found it much easier to attack small businesses with less robust cybersecurity systems in place. They then use the stolen data and access to gain access to larger corporate partners and even customers. Unfortunately, an organization of any size is vulnerable to attack.
Detecting threats is not enough
These increasingly popular attacks wreak havoc on their victimized businesses. Additionally, we know that network-based attacks have become increasingly popular for scammers, often causing significant impacts on victimized businesses. Unfortunately, other security tools may miss these advanced, more robust attacks, and may require interference and assistance from security and IT teams. NDR solutions go beyond signature-based detection by implementing machine learning and data analytics to analyze network traffic and respond to threats in real time.
Need a quick response
NDR tools use machine learning and behavioral analysis to monitor network traffic and develop a baseline of activity. Once they understand the basic behaviors, an NDR can determine when new and different traffic is occurring and what needs immediate investigation and response. This means that when something suspicious is detected on a company’s network, an NDR can recognize it, analyze it, and respond in seconds.
Use of forensic analysis
Using a process of detecting intrusion patterns, focusing on attacker activity, an NDR can determine how threats enter and move through a network.
They analyze network traffic data collected from different sites and network equipment, such as firewalls. Additionally, NDRs monitor abnormal network traffic to detect attacks and determine the nature of attackers.
What cyber threats does network detection and response defend against?
NDR tools have many functions that make them ideal for the day-to-day network security of any organization. An NDR can help defend against many attacks and threats that networks and security teams face today.
Suspicious network traffic that traditional tools miss
Not to be confused with EDR, which focuses on monitoring and preventing endpoint attacks, NDRs focus on monitoring communications and creating real-time network visibility. They also provide timely alerts to incident response teams. Additionally, an NDR can detect patterns and anomalies in all network traffic, stopping and eliminating suspicious or malicious traffic.
Additionally, an NDR differs from traditional cyber detection tools like EDR in that it does not use a specialist to understand malignant activity. Instead, it is up to an organization to investigate the traffic between onsite and remote tasks. By using non-signature-based detection techniques, NDR security devices tend to stop in-progress threat attacks before they can cause damage.
By analyzing traffic that violates safe or recognized browsing behavior, NDR systems continuously monitor and analyze basic corporate network information to establish a baseline of typical network activity. Whenever suspicious network traffic designs deviate from this baseline, NDR tools alert security experts that risks may be occurring on their network.
Non-malicious threats, including insider attacks and credential abuse, are those in which the attacker does not need to install anything on a network or machine. A simple click on a link can cause an employee to infect an organization’s network without knowing it. An NDR can detect these threats, which are hidden behind seemingly normal behavior. These attacks do not have an identifiable code or signature that allows other software to see them. They also don’t tend to have any particular behavior that makes it necessary for an organization to have software beyond traditional heuristic scanners. A non-delivery report now becomes invaluable as a way to recognize this type of violation and respond immediately.
Suspicious accounts and IP addresses
NDR solutions help augment and automate security workflows. For example, a team can automate routine responses to meet specific needs and stop specific threats. Automating network security allows businesses to focus on other vital needs. A great example of an NDR working for security is one that automatically disables an account or blocks an IP address in response to an attack without a team needing to intervene, which brings us to our final point.
Waste of time and money
NDR solutions collect data from all environments and use machine scanning to quickly expose threats. They then provide incident response and threat hunting efforts that security teams don’t have to do on their own.
NDR expands real-time monitoring and analytics while solutions integrate security, automation and response technology to streamline and automate response options.
A team can save time and money with an NDR that provides real-time network insights and analytics and gathers data from a work environment to add relevant contextual information and streamline investigations into violations.
A network and detection and response system is vital for any small or large business that uses a network. Any company whose employees work on a computer, in the office or at home, is susceptible to attack. An NDR can help teams detect many of these threats and determine the best course of action or response for a security team to take. Many of these actions are performed immediately without human interference, reducing response time while helping to eliminate the risk of a data breach. Using techniques such as behavioral analysis, machine learning, and artificial intelligence, a non-delivery report can help bring an organization up to date with network security.
