What is detection in networking?

A network detector is a hardware device or software program designed to help the user detect nearby wireless networks. Laptop users access network detectors every time they search for a new wireless Internet connection, but hackers can also use network detectors. Advanced network detectors are tools used in a practice called war driving, which part of which includes discovering wireless Internet connections while driving around the city and detecting them. A network detector may also be referred to as a network tracker, and network detection software is sometimes referred to as network discovery software.

Network Detection and Response (NDR) is a progressive security solution that provides full visibility into known and unknown threats that cross the network. NDR solutions provide powerful attack detection capabilities for internal and external attackers. AI-based NDR tools are continuously learning and adapting to provide automatic detection of sophisticated and constantly evolving threats. Build a strong foundation of people, processes and technology to accelerate threat detection and response.

The most effective NDR solutions incorporate several machine analysis approaches, such as scenario-based modeling of known tactics, techniques and procedures (TTP) and the thorough inspection of traffic metadata comparing them with known indicators of engagement (IoC), to effectively detect threats. Signature-based detection methods use a unique indicator of commitment identifier (IOC) on a known threat to identify that threat in the future. By collecting data from the network perimeter (to cover north-south traffic) and from network sensors (to cover traffic from east to west), NDR solutions leverage AI and machine learning to develop a basic understanding of normal network traffic flows and therefore also the ability to detect malicious activities that do not follow normal patterns. Organizations increasingly value the response capabilities of NDR solutions to address threats detected by network traffic analysis tools, which focus primarily on detection-only threats and, above all, on basic variations of known threats.

XDR, or Extended Detection and Response, extends endpoint detection and response to provide comprehensive protection. It also collects terminal data from the Cortex XDR agent to provide comprehensive endpoint detection and response (EDR). In addition to signature-based detection, security teams have recognized the need for more comprehensive analysis tools to detect and counter system-wide threats, focused on the network itself and that do not have a prior signature. By taking advantage of these technologies, NDR providers have allowed organizations to improve detection capabilities, determine the confidence and level of risk of a threat, and increasingly automate manual tasks performed by analysts, such as acquiring relevant contextual telemetric information from third parties and applying standardized investigation strategies to further prioritize hazard threats, allowing them to strategically focus on classification and rapid response.

A basic network detector on a wireless card may not be able to detect a network that is not issuing its service set identifier (SSID), but advanced warfare equipment can detect other identifiers transmitted over the network. Networks are increasingly complex and widely distributed, so full visibility is more important than ever in order to detect and stop threats before they become a violation. .
