Capture The Flag (cybersecurity)
Capture the Flag (CTF) in computer security is an exercise in which "flags" are secretly hidden in purposefully- vulnerable programs or websites. It can either be for competitive or educational purposes. Competitors steal flags either from other competitors (attack/defense-style CTFs) or from the organizers (jeopardy-style challenges). Several variations exist. Competitions can including hiding flags in hardware devices, they can be both online or in-person, and can be advanced or entry-level. The game is based on the traditional outdoor sport of the same name. History Capture the Flag (CTF) is a cybersecurity competition that is used as a test of security skills. It was first developed in 1993 at DEFCON, the largest cybersecurity conference in the United States hosted annually in Las Vegas, Nevada. The conference hosts a weekend of cybersecurity competitions including CTF. There are two ways CTF can be played: Jeopardy and Attack-Defense. Both formats test participant’s knowl ...

Computer Security
Computer security, cybersecurity (cyber security), or information technology security (IT security) is the protection of computer systems and networks from attack by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The field has become of significance due to the expanded reliance on computer systems, the Internet, and wireless network standards such as Bluetooth and Wi-Fi, and due to the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity is one of the most significant challenges of the contemporary world, due to both the complexity of information systems and the societies they support. Security is of especially high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, ...

Vulnerability (computing)
Vulnerabilities are flaws in a computer system that weaken the overall security of the device/system. Vulnerabilities can be weaknesses in either the hardware itself, or the software that runs on the hardware. Vulnerabilities can be exploited by a threat actor, such as an attacker, to cross privilege boundaries (i.e. perform unauthorized actions) within a computer system. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness. In this frame, vulnerabilities are also known as the attack surface. Vulnerability management is a cyclical practice that varies in theory but contains common processes which include: discover all assets, prioritize assets, assess or perform a complete vulnerability scan, report on results, remediate vulnerabilities, verify remediation - repeat. This practice generally refers to software vulnerabilities in computing systems. Agile vulnerability management refers preventing attacks by ...

Capture The Flag
Capture the flag (CTF) is a traditional outdoor sport where two or more teams each have a flag (or other markers) and the objective is to capture the other team's flag, located at the team's "base", and bring it safely back to their own base. Enemy players can be "tagged" by players in their home territory and, depending on the rules, they may be out of the game, become members of the opposite team, sent back to their own territory, or frozen in place ("in jail") until freed by a member of their own team. Overview Capture the Flag requires a playing field of some sort. In both indoor and outdoor versions, the field is divided into two clearly designated halves, known as territories. Players form two teams, one for each territory. Each side has a "flag" which is most often a piece of fabric, but can be any object small enough to be easily carried by a person (night time games might use flashlights, glowsticks or lanterns as the "flags"). Sometimes teams wear dark colors at nig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DEF CON
DEF CON (also written as DEFCON, Defcon or DC) is a hacker convention held annually in Las Vegas, Nevada. The first DEF CON took place in June 1993 and today many attendees at DEF CON include computer security professionals, journalists, lawyers, federal government employees, security researchers, students, and hackers with a general interest in software, computer architecture, hardware modification, conference badges, and anything else that can be "hacked". The event consists of several tracks of speakers about computer- and hacking-related subjects, as well as cyber-security challenges and competitions (known as hacking wargames). Contests held during the event are extremely varied, and can range from creating the longest Wi-Fi connection to finding the most effective way to cool a beer in the Nevada heat. Other contests, past and present, include lockpicking, robotics-related contests, art, slogan, coffee wars, scavenger hunt and Capture the Flag. Capture the Flag (CTF) is p ...

DEFCON
The defense readiness condition (DEFCON) is an alert state used by the United States Armed Forces. (DEFCON is not mentioned in the 2010 and newer document) The DEFCON system was developed by the Joint Chiefs of Staff (JCS) and unified and specified combatant commands. It prescribes five graduated levels of readiness (or states of alert) for the U.S. military. It increases in severity from DEFCON 5 (least severe) to DEFCON 1 (most severe) to match varying military situations, with DEFCON 1 signalling the outbreak of nuclear warfare. DEFCONs are a subsystem of a series of Alert Conditions, or LERTCONs, which also include Emergency Conditions (EMERGCONs). Definition The DEFCON level is controlled primarily by the U.S. president and the U.S. Secretary of Defense through the Chairman of the Joint Chiefs of Staff and the Combatant Commanders; each level defines specific security, activation and response scenarios for the personnel in question. Different branches of the U.S. Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wargame (hacking)
In hacking, a wargame (or war game) is a cyber-security challenge and mind sport in which the competitors must exploit or defend a vulnerability in a system or application, or gain or prevent access to a computer system. A wargame usually involves a capture the flag logic, based on pentesting, semantic URL attacks, knowledge-based authentication, password cracking, reverse engineering of software (often JavaScript, C and assembly language), code injection, SQL injections, cross-site scripting, exploits, IP address spoofing, forensics, and other hacking techniques. Wargames for preparedness Wargames are also used as a method of cyberwarfare preparedness. The NATO Cooperative Cyber Defence Centre of Excellence (CCDCOE) organizes an annual event, Locking Shields, which is an international live-fire cyber exercise. The exercise challenges cyber security experts through real-time attacks in fictional scenarios and is used to develop skills in national IT defense strategies. ...

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.

Hackathon
A hackathon (also known as a hack day, hackfest, datathon or codefest; a portmanteau of hacking and marathon) is an event where people engage in rapid and collaborative engineering over a relatively short period of time such as 24 or 48 hours. They are often run using agile software development practices, such as sprint-like design wherein computer programmers and others involved in software development, including graphic designers, interface designers, product managers, project managers, domain experts, and others collaborate intensively on engineering projects, such as software engineering. The goal of a hackathon is to create functioning software or hardware by the end of the event. Hackathons tend to have a specific focus, which can include the programming language used, the operating system, an application, an API, or the subject and the demographic group of the programmers. In other cases, there is no restriction on the type of software being created or the design of the ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
