Zero Trust Security Model
The zero trust security model, also known as zero trust architecture (ZTA), zero trust network architecture or zero trust network access (ZTNA), and sometimes known as perimeterless security, describes an approach to the design and implementation of IT systems. The main concept behind the zero trust security model is "never trust, always verify,” which means that devices should not be trusted by default, even if they are connected to a permissioned network such as a corporate LAN and even if they were previously verified. ZTNA is implemented by establishing strong identity verification, validating device compliance prior to granting access, and ensuring least privilege access to only explicitly authorized resources. Most modern corporate networks consist of many interconnected zones, cloud services and infrastructure, connections to remote and mobile environments, and connections to non-conventional IT, such as IoT devices. The reasoning for zero trust is that the traditional a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IT System
Information technology (IT) is the use of computers to create, process, store, retrieve, and exchange all kinds of Data (computing), data . and information. IT forms part of information and communications technology (ICT). An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a Computer, computer system — including all Computer hardware, hardware, software, and peripheral equipment — operated by a limited group of IT users. Although humans have been storing, retrieving, manipulating, and communicating information since the earliest writing systems were developed, the term ''information technology'' in its modern sense first appeared in a 1958 article published in the ''Harvard Business Review''; authors Harold Leavitt, Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)." Their ...

BeyondCorp
BeyondCorp is an implementation, by Google, of zero-trust computer security concepts creating a zero trust network. It was created in response to the 2009 Operation Aurora. An open source implementation inspired by Google's research paper on an access proxy is known as "transcend". Security mechanisms Unlike traditional VPNs, BeyondCorp's access policies are based on information about a device, its state, and its associated user. BeyondCorp considers both internal networks and external networks to be completely untrusted, and gates access to applications by dynamically asserting and enforcing levels, or “tiers,” of access.

Password Fatigue
Password fatigue is the feeling experienced by many people who are required to remember an excessive number of passwords as part of their daily routine, such as to log in to a computer at work, undo a bicycle lock or conduct banking from an automated teller machine. The concept is also known as password chaos or more broadly as identity chaos. Causes The increasing prominence of information technology and the Internet in employment, finance, recreation and other aspects of people's lives, and the ensuing introduction of secure transaction technology, has led to people accumulating a proliferation of accounts and passwords. According to a survey conducted in February 2020 by password manager Nordpass, a typical user has 100 passwords. Some factors causing password fatigue are: * unexpected demands that a user create a new password * unexpected demands that a user create a new password that uses particular pattern of letters, digits, and special characters * demand that the user ...

Blast Radius
A blast radius is the distance from the source that will be affected when an explosion occurs. A blast radius is often associated with bombs, mines, explosive projectiles ( propelled grenades), and other weapons with an explosive charge. Use in Software Security In cloud computing, the term blast radius is used to designate the impact that a security breach of one single component of an application could have on the overall composite application. Reducing the blast radius of any component is a security good practice. The concept is used in Zero trust security model and Chaos engineering Chaos engineering is the discipline of experimenting on a system in order to build confidence in the system's capability to withstand turbulent conditions in production.

Trust, But Verify
Trust, but verify ( rus, links=no, Доверяй, но проверяй, r=Doveryay, no proveryay, p=dəvʲɪˈrʲæj no prəvʲɪˈrʲæj) is a rhyming Russian proverb. The phrase became internationally known in English after Suzanne Massie, an American scholar, taught it to Ronald Reagan, then president of the United States, the latter of whom used it on several occasions in the context of nuclear disarmament discussions with the Soviet Union. Soviet–American relations Suzanne Massie, an American scholar, met with Ronald Reagan many times while he was president of the United States between 1984 and 1987. She taught him the Russian proverb () meaning 'trust, but verify'. She advised him that "The Russians like to talk in proverbs. It would be nice of you to know a few. You are an actor – you can learn them very quickly." The proverb was adopted as a signature phrase by Reagan, who used it frequently when discussing United States relations with the Soviet Union.

National Cyber Security Centre (United Kingdom)
The National Cyber Security Centre (NCSC) is an organisation of the United Kingdom Government that provides advice and support for the public and private sector in how to avoid computer security threats. Based in London, it became operational in October 2016, and its parent organisation is GCHQ. History The NCSC absorbed and replaced CESG (the information security arm of GCHQ), the Centre for Cyber Assessment (CCA), Computer Emergency Response Team UK (CERT UK) and the cyber-related responsibilities of the Centre for the Protection of National Infrastructure (CPNI). It built on earlier efforts of these organisations and the Cabinet Office to provide guidance on Information Assurance to the UK's wider private sector, such as the "10 Steps" guidance released in January 2015. In pre-launch announcements, the UK government stated that the NCSC would first work with the Bank of England to advise financial institutions on how to bolster online defences.

National Cybersecurity Center Of Excellence
The National Cybersecurity Center of Excellence (NCCoE) is a US government organization that builds and publicly shares solutions to cybersecurity problems faced by U.S. businesses. The center, located in Rockville, Maryland, was established in 2012 through a partnership with the National Institute of Standards and Technology (NIST), the state of Maryland, and Montgomery County. The center is partnered with nearly 20 market-leading IT companies, which contribute hardware, software and expertise. The NCCoE asks industry sector members about their cybersecurity problems, then selects issues that affect an entire sector or reaches across sectors. The center forms a team of people from cybersecurity technology companies, other federal agencies and academia to address each problem. The teams work in the center's labs to build example solutions using commercially available, off-the-shelf products. For each example solution, the NCCoE publishes a practice guide, a collection of the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
