Zeek
Zeek is a free and open-source software network analysis framework. Vern Paxson began development work on Zeek in 1995 at Lawrence Berkeley National Lab. Zeek is a network security monitor (NSM) but can also be used as a network intrusion detection system (NIDS). The Zeek project releases the software under the BSD license. Output Zeek's purpose is to inspect network traffic and generate a variety of logs describing the activity it sees. A complete list of log files is available at the project documentation site. Log example The following is an example of one entry in JSON format from the conn.log: Threat hunting One of Zeek's primary use cases involves cyber threat hunting. Name The principal author, Paxson, originally named the software "Bro" as a warning regarding George Orwell's Big Brother (Nineteen Eighty-Four), Big Brother from the novel ''Nineteen Eighty-Four''. In 2018 the project leadership team decided to rename the software. At LBNL in the 1990s, the developers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Big Brother (Nineteen Eighty-Four)
Big Brother is a character and symbol in George Orwell's dystopian 1949 novel '' Nineteen Eighty-Four''. He is ostensibly the leader of Oceania, a totalitarian state wherein the ruling party, Ingsoc, wields total power "for its own sake" over the inhabitants. The ubiquitous slogan "Big Brother is watching you" serves as a constant reminder that Party members are not entitled to privacy. They are subject to constant surveillance to ensure their ideological purity. This is primarily through omnipresent telescreens that provide two-way video communication and constantly blare propaganda. This close surveillance does not extend to the "proles", who constitute the majority of Oceanic society. They are viewed as inferior beings whose ideas and opinions simply do not matter because they lack both the intelligence and conviction to recognize and assert their latent political power. (In British English, "prole" is an abbreviation of proletarian. It is often derogatory.) "Big Bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unix Security Software
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley (BSD), Microsoft (Xenix), Sun Microsystems (SunOS/Solaris), HP/ HPE (HP-UX), and IBM (AIX). The early versions of Unix—which are retrospectively referred to as "Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows Unix to operate ...

Computer Security Software
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. The defense of computers against intrusion and unauthorized use of resources is called ''computer security''. Similarly, the defense of computer networks is called '' network security''. The subversion of computers or their unauthorized use is referred to using the terms ''cyberwarfare'', ''cybercrime'', or '' security hacking'' (later shortened to ''hacking'' for further references in this article due to issues with ''hacker'', ''hacker culture'' and differences in white/grey/black 'hat' color identification). The computer security software products industry was launched in the second half of the 1970s when computer f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turing Complete
Alan Mathison Turing (; 23 June 1912 – 7 June 1954) was an English mathematician, computer scientist, logician, cryptanalyst, philosopher and theoretical biologist. He was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation with the Turing machine, which can be considered a model of a general-purpose computer. Turing is widely considered to be the father of theoretical computer science. Born in London, Turing was raised in southern England. He graduated from King's College, Cambridge, and in 1938, earned a doctorate degree from Princeton University. During World War II, Turing worked for the Government Code and Cypher School at Bletchley Park, Britain's codebreaking centre that produced Ultra intelligence. He led Hut 8, the section responsible for German naval cryptanalysis. Turing devised techniques for speeding the breaking of German ciphers, including improvements to the ...

Port Mirroring
Port mirroring is used on a network switch to send a copy of network packets seen on one switch port (or an entire VLAN) to a network monitoring connection on another switch port. This is commonly used for network appliances that require monitoring of network traffic such as an intrusion detection system, passive probe or real user monitoring (RUM) technology that is used to support application performance management (APM). Port mirroring on a Cisco Systems switch is generally referred to as ''Switched Port Analyzer'' (SPAN) or ''Remote Switched Port Analyzer'' (RSPAN). Other vendors have different names for it, such as ''Roving Analysis Port'' (RAP) on 3Com switches. Network engineers or administrators use port mirroring to analyze and debug data or diagnose errors on a network. It helps administrators keep a close eye on network performance and alerts them when problems occur. It can be used to mirror either inbound or outbound traffic (or both) on single or multiple inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Tap
A network tap is a system that monitors events on a local network. A tap is typically a dedicated hardware device, which provides a way to access the data flowing across a computer network. The network tap has (at least) three ports: an ''A port'', a ''B port'', and a ''monitor'' port. A tap inserted between A and B passes all traffic (send and receive data streams) through unimpeded in real time, but also copies that same data to its monitor port, enabling a third party to listen. Network taps are commonly used for network intrusion detection systems, VoIP recording, network probes, RMON probes, packet sniffers, and other monitoring and collection devices and software that require access to a network segment. Taps are used in security applications because they are non-obtrusive, are not detectable on the network (having no physical or logical address), can deal with full-duplex and non-shared networks, and will usually ''pass through'' or ''bypass'' traffic even if the tap stops ...

Nineteen Eighty-Four
''Nineteen Eighty-Four'' (also published as ''1984'') is a dystopian novel and cautionary tale by the English writer George Orwell. It was published on 8 June 1949 by Secker & Warburg as Orwell's ninth and final completed book. Thematically, it centres on the consequences of totalitarianism, mass surveillance and repressive regimentation of people and behaviours within society. Orwell, a democratic socialist and an anti-Stalinist, modelled Britain under authoritarian socialism in the novel on the Soviet Union in the era of Stalinism and the practices of censorship and propaganda in Nazi Germany. More broadly, the book examines the role of truth and facts within societies and the ways in which they can be manipulated. The story takes place in an imagined future. The current year is uncertain, but believed to be 1984. Much of the world is in perpetual war. Great Britain, now known as Airstrip One, has become a province of the totalitarian superstate Oceania, which is led b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Orwell
Eric Arthur Blair (25 June 1903 – 21 January 1950) was an English novelist, poet, essayist, journalist, and critic who wrote under the pen name of George Orwell. His work is characterised by lucid prose, social criticism, opposition to all totalitarianism (both authoritarian communism and fascism), and support of democratic socialism. Orwell is best known for his allegorical novella ''Animal Farm'' (1945) and the Utopian and dystopian fiction, dystopian novel ''Nineteen Eighty-Four'' (1949), although his works also encompass literary criticism, poetry, fiction and polemical journalism.
