Intrusion Detection Message Exchange Format
Used as part of computer security, IDMEF (''Intrusion Detection Message Exchange Format'') is a data format used to exchange information between software enabling intrusion detection, intrusion prevention, security information collection and management systems that may need to interact with them. IDMEF messages are designed to be processed automatically. The details of the format are described in the RFC 4765. This RFC presents an implementation of the XML data model and the associated DTD. The requirements for this format are described in RFC 4766, and the recommended transport protocol (IDXP) is documented in RFC 4767 IDMEF The purpose of IDMEF is to define data formats and exchange procedures for sharing information of interest to intrusion detection and response systems and to the management systems that may need to interact with them. It is used in computer security for incidents reporting and exchanging. It is intended for easy automatic processing. IDMEF is a well-structured ...

Intrusion Detection
An intrusion detection system (IDS; also intrusion prevention system or IPS) 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 reported either 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 (recogni ...

Computer Security
Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from attack by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The field has become of significance due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, ...

Ping Of Death
A ping of death is a type of attack on a computer system that involves sending a malformed or otherwise malicious ping to a computer. A correctly formed ping packet is typically 56 bytes in size, or 64 bytes when the Internet Control Message Protocol (ICMP) header is considered, and 84 bytes including Internet Protocol (IP) version 4 header. However, any IPv4 packet (including pings) may be as large as 65,535 bytes. Some computer systems were never designed to properly handle a ping packet larger than the maximum packet size because it violates the Internet Protocol. Like other large but well-formed packets, a ping of death is fragmented into groups of 8 octets before transmission. However, when the target computer reassembles the malformed packet, a buffer overflow can occur, causing a system crash and potentially allowing the injection of malicious code. In early implementations of TCP/IP, this bug is easy to exploit and can affect a wide varie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Operations Center
A network operations center (NOC, pronounced like the word ''knock''), also known as a "network management center", is one or more locations from which network monitoring and control, or network management, is exercised over a computer, telecommunication or satellite network. __TOC__ History The earliest NOCs started during the 1960s. A Network Control Center was opened in New York by AT&T in 1962 which used status boards to display switch and routing information, in real-time, from AT&T's most important toll switches. AT&T later replaced this Network Control Center with a modernized NOC in 1977, located in Bedminster, New Jersey. Purpose NOCs are implemented by business organizations, public utilities, universities, and government agencies that oversee complex networking environments that require high availability. NOC personnel are responsible for monitoring one or many networks for certain conditions that may require special attention to avoid degraded service. Organization ...
