TCP Reset Attack
TCP reset attack, also known as a "forged TCP reset" or "spoofed TCP reset", is a way to terminate a TCP connection by sending a forged TCP reset packet. This tampering technique can be used by a firewall or abused by a malicious attacker to interrupt Internet connections. The Great Firewall of China, and Iranian Internet censors are known to use TCP reset attacks to interfere with and block connections, as a major method to carry out Internet censorship. Background The Internet is a system for individual computers to exchange electronic messages, or packets of data. This system includes hardware to carry the messages (such as copper and fiber optics cables) and a formalized system for formatting the messages, called "protocols". The basic protocol used on the Internet is the Internet Protocol (IP), which is usually coupled with additional protocols such as TCP (Transmission Control Protocol) or UDP (User Datagram Protocol). TCP/IP is the protocol set used for email and web br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmission Control Protocol
The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP. TCP provides reliable, ordered, and error-checked delivery of a stream of octets (bytes) between applications running on hosts communicating via an IP network. Major internet applications such as the World Wide Web, email, remote administration, and file transfer rely on TCP, which is part of the Transport Layer of the TCP/IP suite. SSL/TLS often runs on top of TCP. TCP is connection-oriented, and a connection between client and server is established before data can be sent. The server must be listening (passive open) for connection requests from clients before a connection is established. Three-way handshake (active open), retransmission, and error detection adds to reliability but lengthens latency. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyberwarfare
Cyberwarfare is the use of cyber attacks against an enemy state, causing comparable harm to actual warfare and/or disrupting vital computer systems. Some intended outcomes could be espionage, sabotage, propaganda, manipulation or economic warfare. There is significant debate among experts regarding the definition of cyberwarfare, and even if such a thing exists. One view is that the term is a misnomer, since no cyber attacks to date could be described as war. An alternative view is that it is a suitable label for cyber attacks which cause physical damage to people and objects in the real world. Many countries including the United States, United Kingdom, Russia, China, Israel, Iran, and North Korea have active cyber capabilities for offensive and defensive operations. As states explore the use of cyber operations and combine capabilities, the likelihood of physical confrontation and violence playing out as a result of, or part of, a cyber operation is increased. However, meet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Network Neutrality
Network neutrality, often referred to as net neutrality, is the principle that Internet service providers (ISPs) must treat all Internet communications equally, offering users and online content providers consistent rates irrespective of content, website, platform, application, type of equipment, source address, a destination address, or method of communication. Supporters of net neutrality argue that it prevents cable companies from filtering Internet content without a court order, fosters freedom of speech and democratic participation, promotes competition and innovation, prevents dubious services, maintains the end-to-end principle, and that users would be intolerant of slow-loading websites. Opponents of net neutrality argue that it reduces investment, deters competition, increases taxes, imposes unnecessary regulations, prevents the Internet from being accessible to poor people, prevents Internet traffic from being allocated to the most needed users, that large Intern ...

DNS Hijacking
DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. This can be achieved by malware that overrides a computer's TCP/IP configuration to point at a rogue DNS server under the control of an attacker, or through modifying the behaviour of a trusted DNS server so that it does not comply with internet standards. These modifications may be made for malicious purposes such as phishing, for self-serving purposes by Internet service providers (ISPs), by the Great Firewall of China and public/router-based online DNS server providers to direct users' web traffic to the ISP's own web servers where advertisements can be served, statistics collected, or other purposes of the ISP; and by DNS service providers to block access to selected domains as a form of censorship. Technical background One of the functions of a DNS server is to translate a domain name into an IP address that applications need to connect to a ...

Collateral Damage
Collateral damage is any death, injury, or other damage inflicted that is an incidental result of an activity. Originally coined by military operations, it is now also used in non-military contexts. Since the development of precision guided munitions in the 1970s, military forces often claim to have gone to great lengths to minimize collateral damage. Critics of use of the term "collateral damage" see it as a euphemism that dehumanizes non-combatants killed or injured during combat, used to reduce the perceived culpability of military leadership in failing to prevent non-combatant casualties. Collateral damage does not include civilian casualties caused by military operations that are intended to terrorize or kill enemy civilians (e.g., the bombing of Chongqing during World War II). Etymology The word "collateral" comes from medieval Latin word ''collateralis'', from ''col-'', "together with" + ''lateralis'' (from ''latus'', ''later-'', "side" ) and is otherwise mainly use ...

Virtual Private Network
A virtual private network (VPN) extends a private network across a public network and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. The benefits of a VPN include increases in functionality, security, and management of the private network. It provides access to resources that are inaccessible on the public network and is typically used for remote workers. Encryption is common, although not an inherent part of a VPN connection. A VPN is created by establishing a virtual point-to-point connection through the use of dedicated circuits or with tunneling protocols over existing networks. A VPN available from the public Internet can provide some of the benefits of a wide area network (WAN). From a user perspective, the resources available within the private network can be accessed remotely. Types Virtual private networks may be classified into several categories: ;Remote ac ...

Malware
Malware (a portmanteau for ''malicious software'') is any software intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive access to information, or which unknowingly interferes with the user's computer security and privacy. By contrast, software that causes harm due to some deficiency is typically described as a software bug. Malware poses serious problems to individuals and businesses on the Internet. According to Symantec's 2018 Internet Security Threat Report (ISTR), malware variants number has increased to 669,947,865 in 2017, which is twice as many malware variants as in 2016. Cybercrime, which includes malware attacks as well as other crimes committed by computer, was predicted to cost the world economy $6 trillion USD in 2021, and is increasing at a rate of 15% per year. Many types of malware exist, including computer viruses, worms, Trojan ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
