An intrusion detection system 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.
Network security consists of the policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, which is controlled by the network administrator. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs: conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access. Network security is involved in organizations, enterprises, and other types of institutions. It does as its title explains: it secures the network, as well as protecting and overseeing operations being done. The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password.
Snort is a free open source network intrusion detection system (IDS) and intrusion prevention system (IPS) created in 1998 by Martin Roesch, founder and former CTO of Sourcefire. Snort is now developed by Cisco, which purchased Sourcefire in 2013.
Suricata is an open source-based intrusion detection system (IDS) and intrusion prevention system (IPS). It was developed by the Open Information Security Foundation (OISF). A beta version was released in December 2009, with the first standard release following in July 2010.
A host-based intrusion detection system (HIDS) is an intrusion detection system that is capable of monitoring and analyzing the internals of a computing system as well as the network packets on its network interfaces, similar to the way a network-based intrusion detection system (NIDS) operates. This was the first type of intrusion detection software to have been designed, with the original target system being the mainframe computer where outside interaction was infrequent.
Kismet is a network detector, packet sniffer, and intrusion detection system for 802.11 wireless LANs. Kismet will work with any wireless card which supports raw monitoring mode, and can sniff 802.11a, 802.11b, 802.11g, and 802.11n traffic. The program runs under Linux, FreeBSD, NetBSD, OpenBSD, and Mac OS X. The client can also run on Microsoft Windows, although, aside from external drones, there's only one supported wireless hardware available as packet source.
In the field of computer network administration, pcap is an application programming interface (API) for capturing network traffic. While the name is an abbreviation of packet capture, that is not the API's proper name. Unix-like systems implement pcap in the libpcap library; for Windows, there is a port of libpcap named WinPcap that is no longer supported or developed, and a port named Npcap for Windows 7 and later that is still supported.
Argus – the Audit Record Generation and Utilization System is the first implementation of network flow monitoring, and is an ongoing open source network flow monitor project. Started by Carter Bullard in 1984 at Georgia Tech, and developed for cyber security at Carnegie Mellon University in the early 1990s, Argus has been an important contributor to Internet cyber security technology over its 30 years..
Zeek is a free and open-source software network analysis framework; it was first developed in 1994 by Vern Paxson and was originally named in reference to George Orwell's Big Brother from his novel Nineteen Eighty-Four. It is designed to be a network security monitor (NSM) but can also be used as a network intrusion detection system (NIDS) coupled with additional live analysis of network events. It is released under the BSD license.
OSSIM is an open source security information and event management system, integrating a selection of tools designed to aid network administrators in computer security, intrusion detection and prevention.
Intrusion detection system evasion techniques are modifications made to attacks in order to prevent detection by an intrusion detection system (IDS). Almost all published evasion techniques modify network attacks. The 1998 paper Insertion, Evasion, and Denial of Service: Eluding Network Intrusion Detection popularized IDS evasion, and discussed both evasion techniques and areas where the correct interpretation was ambiguous depending on the targeted computer system. The 'fragroute' and 'fragrouter' programs implement evasion techniques discussed in the paper. Many web vulnerability scanners, such as 'Nikto', 'whisker' and 'Sandcat', also incorporate IDS evasion techniques.
Prelude SIEM is a Security information and event management (SIEM).
Sourcefire, Inc was a technology company that developed network security hardware and software. The company's Firepower network security appliances were based on Snort, an open-source intrusion detection system (IDS). Sourcefire was acquired by Cisco for $2.7 billion in July 2013.
Computer security software or cybersecurity software is any computer program designed to influence information security. This is often taken in the context of defending computer systems or data, yet can incorporate programs designed specifically for subverting computer systems due to their significant overlap, and the adage that the best defense is a good offense.
Network Security Toolkit (NST) is a Linux-based Live DVD/USB Flash Drive that provides a set of free and open-source computer security and networking tools to perform routine security and networking diagnostic and monitoring tasks. The distribution can be used as a network security analysis, validation and monitoring tool on servers hosting virtual machines. The majority of tools published in the article "Top 125 security tools" by Insecure.org are available in the toolkit. NST has package management capabilities similar to Fedora and maintains its own repository of additional packages.
Security information and event management (SIEM) is a field within the field of computer security, where software products and services combine security information management (SIM) and security event management (SEM). They provide real-time analysis of security alerts generated by applications and network hardware. Vendors sell SIEM as software, as appliances, or as managed services; these products are also used to log security data and generate reports for compliance purposes. The term and the initialism SIEM was coined by Mark Nicolett and Amrit Williams of Gartner in 2005.
Aanval is a commercial SIEM product designed specifically for use with Snort, Suricata, and Syslog data. Aanval has been in active development since 2003 and remains one of the longest running Snort capable SIEM products in the industry. Aanval is Dutch for "attack".
ACARM-ng is an open source IDS/IPS system. ACARM-ng is an alert correlation software which can significantly facilitate analyses of traffic in computer networks. It is responsible for collection and correlation of alerts sent by network and host sensors, also referred to as NIDS and HIDS respectively. Correlation process aims to reduce the total number of messages that need to be viewed by a system administrator to as few as possible by merging similar events into groups representing logical pieces of malicious activity.
Used as part of computer security, IDMEF 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
Sagan is an open source (GNU/GPLv2) multi-threaded, high performance, real-time log analysis & correlation engine developed by Quadrant Information Security that runs on Unix operating systems. It is written in C and uses a multi-threaded architecture to deliver high performance log & event analysis. Sagan's structure and rules work similarly to the Sourcefire Snort IDS/IPS engine. This allows Sagan to be compatible with Snort or Suricata rule management softwares and give Sagan the ability to correlate with Snort IDS/IPS data.
