MAC Spoofing
MAC spoofing is a technique for changing a factory-assigned Media Access Control (MAC) address of a network interface on a networked device. The MAC address that is hard-coded on a network interface controller (NIC) cannot be changed. However, many drivers allow the MAC address to be changed. Additionally, there are tools which can make an operating system believe that the NIC has the MAC address of a user's choosing. The process of masking a MAC address is known as MAC spoofing. Essentially, MAC spoofing entails changing a computer's identity, for any reason. Motivation Changing the assigned MAC address may allow the user to bypass access control lists on servers or routers, either hiding a computer on a network or allowing it to impersonate another network device. It may also allow the user to bypass MAC address blacklisting to regain access to a Wi-Fi network. MAC spoofing is done for legitimate and illicit purposes alike.

MAC Address
A MAC address (short for medium access control address or media access control address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the medium access control protocol sublayer of the data link layer. As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator. MAC addresses are primarily assigned by device manufacturers, and are therefore often referred to as the burned-in address, or as an Ethernet hardware address, hardware address, or physical address. Each address can be stored in the interface hardware, such as its read-only memory, or by a firmware mechanism. Many network interfaces, however, ...

MAC Filtering
In computer networking, MAC address filtering is a network access control method whereby the MAC address assigned to each network interface controller is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists. While the restriction of network access through the use of lists is straightforward, an individual person is not identified by a MAC address, rather a device only, so an authorized person will need to have a whitelist entry for each device that they would like to access the network. While giving a network some additional protection, MAC filtering can be circumvented by using a packet analyzer to find a valid MAC and then using MAC spoofing to access the network using that address. MAC address filtering can be considered as security through obscurity because the effectiveness is based on "the secrecy of th ...

Promiscuous Mode
In computer networking, promiscuous mode is a mode for a wired network interface controller (NIC) or wireless network interface controller (WNIC) that causes the controller to pass all traffic it receives to the central processing unit (CPU) rather than passing only the frames that the controller is specifically programmed to receive. This mode is normally used for packet sniffing that takes place on a router or on a computer connected to a wired network or one being part of a wireless LAN. Interfaces are placed into promiscuous mode by Network bridge, software bridges often used with hardware virtualization. In IEEE 802 networks such as Ethernet or IEEE 802.11, each frame includes a destination MAC address. In non-promiscuous mode, when a NIC receives a frame, it drops it unless the frame is addressed to that NIC's MAC address or is a Broadcasting (networking), broadcast or multicast addressed frame. In promiscuous mode, however, the NIC allows all frames through, thus allowin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IP Address Spoofing
In computer networking, IP address spoofing or IP spoofing is the creation of Internet Protocol (IP) packets with a false source IP address, for the purpose of impersonating another computing system. Background The basic protocol for sending data over the Internet network and many other computer networks is the Internet Protocol (IP). The protocol specifies that each IP packet must have a header which contains (among other things) the IP address of the sender of the packet. The source IP address is normally the address that the packet was sent from, but the sender's address in the header can be altered, so that to the recipient it appears that the packet came from another source. The protocol requires the receiving computer to send back a response to the source IP address therefore spoofing is mainly used when the sender can anticipate the network response or does not care about the response. The source IP address provides only limited information about the sender. It may pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcast Domain
A broadcast domain is a logical division of a computer network, in which all nodes can reach each other by broadcast at the data link layer. A broadcast domain can be within the same LAN segment or it can be bridged to other LAN segments. In terms of current popular technologies, any computer connected to the same Ethernet repeater or switch is a member of the same broadcast domain. Further, any computer connected to the same set of interconnected switches or repeaters is a member of the same broadcast domain. Routers and other network-layer devices form boundaries between broadcast domains. The notion of a broadcast domain can be compared with a collision domain, which would be all nodes on the same set of inter-connected repeaters and divided by switches and network bridges. Collision domains are generally smaller than and contained within broadcast domains. While some data-link-layer devices are able to divide the collision domains, broadcast domains are only divided by n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JSTOR
JSTOR ( ; short for ''Journal Storage'') is a digital library of academic journals, books, and primary sources founded in 1994. Originally containing digitized back issues of academic journals, it now encompasses books and other primary sources as well as current issues of journals in the humanities and social sciences. It provides full-text searches of almost 2,000 journals. Most access is by subscription but some of the site is public domain, and open access content is available free of charge. History William G. Bowen, president of Princeton University from 1972 to 1988, founded JSTOR in 1994. JSTOR was originally conceived as a solution to one of the problems faced by libraries, especially research and university libraries, due to the increasing number of academic journals in existence. Most libraries found it prohibitively expensive in terms of cost and space to maintain a comprehensive collection of journals. By digitizing many journal titles, JSTOR allowed libraries ...

Hacktivism
Hacktivism (or hactivism; a portmanteau of ''hack'' and ''activism''), is the use of computer-based techniques such as hacking as a form of civil disobedience to promote a political agenda or social change. A form of Internet activism with roots in hacker culture and hacker ethics, its ends are often related to free speech, human rights, or freedom of information movements. Hacktivist activities span many political ideals and issues. Hyphanet, a peer-to-peer platform for censorship-resistant communication, is a prime example of translating political thought and freedom of speech into code. Hacking as a form of activism can be carried out by a singular activist or through a network of activists, such as Anonymous and WikiLeaks, working in collaboration toward common goals without an overarching authority figure. For context, according to a statement by the U.S. Justice Department, Julian Assange, the founder of WikiLeaks, plotted with hackers connected to the "Anonymous" and "L ...

Linux Kernel
The Linux kernel is a Free and open-source software, free and open source Unix-like kernel (operating system), kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the kernel for the GNU operating system (OS) which was created to be a free software, free replacement for Unix. Since the late 1990s, it has been included in many Linux distributions, operating system distributions, many of which are called Linux. One such Linux kernel operating system is Android (operating system), Android which is used in many mobile and embedded devices. Most of the kernel code is written in C (programming language), C as supported by the GNU compiler collection (GCC) which has extensions beyond standard C. The code also contains assembly language, assembly code for architecture-specific logic such as optimizing memory use and task execution. The kernel has a Modular programming, modular design such that modules can be inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
