Vern Paxson
Vern Edward Paxson is a Professor of Computer Science at the University of California, Berkeley. He also leads the Networking and Security Group at the International Computer Science Institute in Berkeley, California. His interests range from transport protocols to intrusion detection and worms. He is an active member of the Internet Engineering Task Force (IETF) community and served as the chair of the Internet Research Task Force, IRTF from 2001 until 2005. From 1998 to 1999 he served on the IESG as Transport Area Director for the IETF. In 2006 Paxson was inducted as a List of Fellows of the Association for Computing Machinery, Fellow of the Association for Computing Machinery (ACM). The SIGCOMM, ACM's Special Interest Group on Data Communications (SIGCOMM) gave Paxson its 2011 award, "for his seminal contributions to the fields of Internet measurement and Internet security, and for distinguished leadership and service to the Internet community."

Flex Lexical Analyser
Flex (fast lexical analyzer generator) is a free and open-source software alternative to lex. It is a computer program that generates lexical analyzers (also known as "scanners" or "lexers"). It is frequently used as the lex implementation together with Berkeley Yacc parser generator on BSD-derived operating systems (as both lex and yacc are part of POSIX), or together with GNU bison (a version of yacc) in *BSD ports and in Linux distributions. Unlike Bison, flex is not part of the GNU Project and is not released under the GNU General Public License, although a manual for Flex was produced and published by the Free Software Foundation. History Flex was written in C around 1987 by Vern Paxson, with the help of many ideas and much inspiration from Van Jacobson. Original version by Jef Poskanzer. The fast table representation is a partial implementation of a design done by Van Jacobson. The implementation was done by Kevin Gong and Vern Paxson. Example lexical analyzer This is ...

Computer Security Academics
A computer is a machine that can be programmed to Execution (computing), carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as Computer program, programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the Computer hardware, hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devi ...

DDoS
In computing, a denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host A host is a person responsible for guests at an event or for providing hospitality during it. Host may also refer to: Places * Host, Pennsylvania, a village in Berks County People *Jim Host (born 1937), American businessman * Michel Host ... connected to a Computer network, network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources. More sophisticated strategies are required to mitigate this type of attack, as simply attempting to block a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Background Noise
Internet background noise (IBN, also known as Internet background radiation) consists of data packets on the Internet which are addressed to IP addresses or ports where there is no network device set up to receive them. These packets often contain unsolicited commercial or network control messages, or are the result of port scans and worm activities. Smaller devices such as DSL modems may have a hard-coded IP address to look up the correct time using the Network Time Protocol. If, for some reason, the hard-coded NTP server is no longer available, faulty software might retry failed requests up to every second, which, if many devices are affected, generates a significant amount of unnecessary request traffic. Historical context In the first 10 years of the Internet, there was very little background noise but with its commercialization in the 1990s the noise factor became a permanent feature. The Conficker worm in recent times was responsible for a large amount of background nois ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Denial-of-service Attack
In computing, a denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources. More sophisticated strategies are required to mitigate this type of attack, as simply attempting to block a single source is insufficient because there are multiple sources. A DoS or DDoS attack is analogous to a group of people crowding the entry door of a shop, making it hard for legitimate customers to enter, thus disrupting trade. Criminal perpetrators of DoS attacks oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Dr. Paxson originally named the software "Bro" as a warning regarding George Orwell's 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 ran their sensors as a pseudo-user named “zeek”, ...

Computer Science
Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to Applied science, practical disciplines (including the design and implementation of Computer architecture, hardware and Computer programming, software). Computer science is generally considered an area of research, academic research and distinct from computer programming. Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and for preventing Vulnerability (computing), security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Progr ...
