Arbitrary Code Execution
In computer security, arbitrary code execution (ACE) is an attacker's ability to run any commands or code of the attacker's choice on a target machine or in a target process. An arbitrary code execution vulnerability is a security flaw in software or hardware allowing arbitrary code execution. A program that is designed to exploit such a vulnerability is called an arbitrary code execution exploit. The ability to trigger arbitrary code execution over a network (especially via a wide-area network such as the Internet) is often referred to as remote code execution (RCE or RCX). Arbitrary code execution signifies that if someone sends a specially designed set of data to a computer, they can make it do whatever they want. Even though this particular weakness may not cause actual problems in the real world, researchers have discussed whether it suggests a natural tendency for computers to have vulnerabilities that allow unauthorized code execution. Vulnerability types There are a nu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Security
Computer security (also cybersecurity, digital security, or information technology (IT) security) is a subdiscipline within the field of information security. It consists of the protection of computer software, systems and computer network, networks from Threat (security), threats that can lead to unauthorized information disclosure, theft or damage to computer hardware, hardware, software, or Data (computing), data, as well as from the disruption or misdirection of the Service (economics), services they provide. The significance of the field stems from the expanded reliance on computer systems, the Internet, and wireless network standards. Its importance is further amplified by the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity has emerged as one of the most significant new challenges facing the contemporary world, due to both the complexity of information systems and the societi ...

Privilege (computing)
In computing, privilege is defined as the delegation of authority to perform security-relevant functions on a computer system. A privilege allows a user to perform an action with security consequences. Examples of various privileges include the ability to create a new user, install software, or change kernel functions. Users who have been delegated extra levels of control are called privileged. Users who lack most privileges are defined as unprivileged, regular, or normal users. Theory Privileges can either be automatic, granted, or applied for. An automatic privilege exists when there is no requirement to have permission to perform an action. For example, on systems where people are required to log into a system to use it, logging out will not require a privilege. Systems that do not implement file protection - such as MS-DOS - essentially give unlimited privilege to perform any action on a file. A granted privilege exists as a result of presenting some credential to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Super Mario Bros
is a 1985 Platformer, platform game developed and published by Nintendo for the Nintendo Entertainment System (NES). It is the successor to the 1983 arcade game ''Mario Bros.'' and the first game in the ''Super Mario'' series. It was originally released in September 1985 in Japan for the Family Computer; following a US test market release for the NES, it was converted to international arcade game, arcades on the Nintendo VS. System in early 1986. The NES version received a wide release in North America that year and in PAL regions in 1987. Players control Mario, or his brother Luigi in the multiplayer mode, to traverse the Mushroom Kingdom in order to rescue Princess Peach, Princess Toadstool from King Koopa (later named Bowser). They traverse side-scrolling video game, side-scrolling stages while avoiding hazards such as enemies and pits with the aid of power-ups such as the Super Mushroom, Fire Flower and Starman (Mario), Starman. The game was designed by Shigeru Miyamot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snake (video Game Genre)
Snake is a video game genre, genre of action game, action video games where the player maneuvers the end of a growing line, often themed as a snake. The player must keep the snake from colliding with both other obstacles and itself, which gets harder as the snake lengthens. The genre originated in the 1976 competitive arcade video game ''Blockade (video game), Blockade'' from Gremlin Industries where the goal is to survive longer than the other player. ''Blockade'' and the initial wave of clones that followed were purely abstract and did not use ''snake'' terminology. The concept evolved into a single-player variant where a line with a head and tail gets longer with each piece of food eaten—often apples or eggs—increasing the likelihood of self-collision. The simplicity and low technical requirements of snake games have resulted in hundreds of versions, some of which have the word ''snake'' or ''worm'' in the title. The 1982 ''Tron (video game), Tron'' arcade video game, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pong
''Pong'' is a 1972 sports video game developed and published by Atari for arcades. It is one of the earliest arcade video games; it was created by Allan Alcorn as a training exercise assigned to him by Atari co-founder Nolan Bushnell, but Bushnell and Atari co-founder Ted Dabney were surprised by the quality of Alcorn's work and decided to manufacture the game. Bushnell based the game's concept on an electronic ping-pong game included in the Magnavox Odyssey, the first home video game console. In response, Magnavox later sued Atari for patent infringement. ''Pong'' was the first commercially successful video game, and it helped to establish the video game industry along with the Magnavox Odyssey. Soon after its release, several companies began producing games that closely mimicked its gameplay. Eventually, Atari's competitors released new types of video games that deviated from ''Pong'''s original format to varying degrees, and this, in turn, led Atari to encourage its sta ...

Speedrunning
Speedrunning is the act of playing a video game, or section of a video game, with the goal of completing it as fast as possible. Speedrunning often involves following planned routes, which may incorporate sequence breaking and exploit glitches that allow sections to be skipped or completed more quickly than intended. Tool-assisted speedrun, Tool-assisted speedrunning (TAS) is a subcategory of speedrunning that uses Emulator, emulation software or additional tools to create a precisely controlled sequence of inputs. Many online communities revolve around speedrunning specific games; community leaderboard rankings for individual games form the primary competitive metric for speedrunning. Racing between two or more speedrunners is also a popular form of competition. Videos and Livestreaming, livestreams of speedruns are shared via the internet on media sites such as YouTube and Twitch (service), Twitch. Speedruns are sometimes showcased at marathon events, which are Gaming convent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protected Memory
Memory protection is a way to control memory access rights on a computer, and is a part of most modern instruction set architectures and operating systems. The main purpose of memory protection is to prevent a process from accessing memory that has not been allocated to it. This prevents a bug or malware within a process from affecting other processes, or the operating system itself. Protection may encompass all accesses to a specified area of memory, write accesses, or attempts to execute the contents of the area. An attempt to access unauthorized memory results in a hardware fault, e.g., a segmentation fault, storage violation exception, generally causing abnormal termination of the offending process. Memory protection for computer security includes additional techniques such as address space layout randomization and executable-space protection. Methods Segmentation Segmentation refers to dividing a computer's memory into segments. A reference to a memory location ...
