Extended Detection And Response
Extended detection and response (XDR) is a cybersecurity technology that monitors and mitigates cyber security threats. Concept The term was coined by Nir Zuk of Palo Alto Networks in 2018. According to Chapple, Stewart and Gibson, XDR is not so much another tool as the collection and integration of several concepts into a single solution, the components varying from vendor to vendor and often including NTA (network traffic analysis), NIDS and NIPS. According to Gartner: The system works by collecting and correlating data across various network points such as servers, email, cloud workloads, and endpoints. The data is then analyzed and correlated, lending it visibility and context, and revealing advanced threats. Thereafter, the threats are prioritized, analyzed, and sorted to prevent security collapses and data loss. The XDR system helps organizations to have a higher level of cyber awareness, enabling cyber security teams to identify and eliminate security vulnerabilitie ...

Cybersecurity
Computer security (also cybersecurity, digital security, or information technology (IT) security) is a subdiscipline within the field of information security. It consists of the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The significance of the field stems from the expanded reliance on computer systems, the Internet, and wireless network standards. Its importance is further amplified by the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity has emerged as one of the most significant new challenges facing the contemporary world, due to both the complexity of information systems and the societies they support. Security is particularly crucial for systems that govern large-scale sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Network Intrusion-detection System
An intrusion detection system (IDS) is a device or software application that monitors a network or systems for malicious activity or policy violations. Any intrusion activity or violation is typically either reported to an administrator or collected centrally using a security information and event management (SIEM) system. A SIEM system combines outputs from multiple sources and uses alarm filtering techniques to distinguish malicious activity from false alarms. IDS types range in scope from single computers to large networks. The most common classifications are network intrusion detection systems (NIDS) and host-based intrusion detection systems (HIDS). A system that monitors important operating system files is an example of an HIDS, while a system that analyzes incoming network traffic is an example of an NIDS. It is also possible to classify IDS by detection approach. The most well-known variants are signature-based detection (recognizing bad patterns, such as exploitation ...
