DNS Over TLS
DNS over TLS (DoT) is a network security protocol for encrypting and wrapping Domain Name System (DNS) queries and answers via the Transport Layer Security (TLS) protocol. The goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data via man-in-the-middle attacks. The well-known port number for DoT is 853. While DNS over TLS is applicable to any DNS transaction, it was first standardized for use between stub or forwarding resolvers and recursive resolvers, in in May of 2016. Subsequent IETF efforts specify the use of DoT between recursive and authoritative servers ("Authoritative DNS over TLS" or "ADoT") and a related implementation between authoritative servers (Zone Transfer-over-TLS or "xfr-over-TLS"). Server software BIND supports DoT connections as of version 9.17. Earlier versions offered DoT capability by proxying through stunnel. Unbound has supported DNS over TLS since 22 January 2023. Unwind has supported ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Internet Standard
In computer network engineering, an Internet Standard is a normative specification of a technology or methodology applicable to the Internet. Internet Standards are created and published by the Internet Engineering Task Force (IETF). They allow interoperation of hardware and software from different sources which allows internets to function. As the Internet became global, Internet Standards became the lingua franca of worldwide communications. Engineering contributions to the IETF start as an Internet Draft, may be promoted to a Request for Comments, and may eventually become an Internet Standard. An Internet Standard is characterized by technical maturity and usefulness. The IETF also defines a Proposed Standard as a less mature but stable and well-reviewed specification. A Draft Standard was an intermediate level, discontinued in 2011. A Draft Standard was an intermediary step that occurred after a Proposed Standard but prior to an Internet Standard. As put in RFC 2026: In ge ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Rooting (Android)
Rooting is the process by which users of Android (operating system), Android devices can attain Privilege escalation, privileged control (known as root access) over various subsystems of the device, usually smartphones and tablet computer, tablets. Because Android is based on a modified version of the Linux kernel, rooting an Android boot, Android device gives access to administrative (superuser) permissions similar to those on Linux or any other Unix-like Operating system fingerprinting, operating system such as FreeBSD or macOS. Rooting is often performed to overcome limitations that mobile network operator, carriers and Electronic hardware, hardware manufacturers put on some devices. Thus, rooting allows the users to alter or replace System software, system applications and settings, run specialized Application software, applications ("apps") that require administrator-level permissions, or perform other operations that are otherwise inaccessible to a normal Android One, Androi ...

End-to-end Encryption
End-to-end encryption (E2EE) is a method of implementing a secure communication system where only communicating users can participate. No one else, including the system provider, telecom providers, Internet providers or malicious actors, can access the cryptographic keys needed to read or send messages. End-to-end encryption prevents data from being read or secretly modified, except by the true sender and intended recipients. Frequently, the messages are relayed from the sender to the recipients by a service provider. However, messages are encrypted by the sender and no third party, including the service provider, has the means to decrypt them. The recipients retrieve the encrypted messages and decrypt them independently. Since third parties cannot decrypt the data being communicated or stored, services that provide end-to-end encryption are better at protecting user data when they are affected by data breaches. Such services are also unable to share user data with governm ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Authoritative Name Server
A name server is a computer application that implements a network service for providing responses to queries against a directory service. It translates an often humanly meaningful, text-based identifier to a system-internal, often numeric identification or addressing component. This service is performed by the server in response to a service protocol request. An example of a name server is the server component of the Domain Name System (DNS), one of the two principal namespaces of the Internet. The most important function of DNS servers is the translation (resolution) of human-memorable domain names and hostnames into the corresponding numeric Internet Protocol (IP) addresses, the second principal name space of the Internet which is used to identify and locate computer systems and resources on the Internet. Domain name server The Internet maintains two principal namespaces: the domain name hierarchyRFC 1034, ''Domain Names—Concepts and Facilities'', P. Mockapetris, The Int ...

Parental Controls
Parental controls are features which may be included in digital television services, computers and video games, mobile devices and software to assist parents in their ability to restrict certain content viewable by their children. This may be content they deem inappropriate for their age, maturity level or feel is aimed more at an adult audience. Parental controls fall into roughly four categories: '' content filters'', which limit access to age inappropriate content; ''usage controls'', which constrain the usage of these devices such as placing time-limits on usage or forbidding certain types of usage; ''computer usage management tools'', which enforces the use of certain software; and '' monitoring'', which can track location and activity when using the devices. Content filters were the first popular type of parental controls to limit access to Internet content. Television stations also began to introduce V-Chip technology to limit access to television content. Modern usage ...

Public Recursive Name Server
A public recursive name server (also called public DNS resolver) is a name server service that networked computers may use to query the Domain Name System (DNS), the decentralized Internet naming system, in place of (or in addition to) name servers operated by the local Internet service provider (ISP) to which the devices are connected. Reasons for using these services include: * speed, compared to using ISP DNS services * filtering (security, ad-blocking, porn-blocking, etc.) * reporting * avoiding censorship * redundancy (smart caching) * access to unofficial alternative top level domains not found in the official DNS root zone The DNS root zone is the top-level DNS zone in the hierarchical namespace of the Domain Name System (DNS) of the Internet. Before October 1, 2016, the root zone had been overseen by the Internet Corporation for Assigned Names and Numbers (ICANN ... *temporary unavailability of the ISP's name server Public DNS resolver operators often cite increas ...

Systemd-resolved
systemd is a software suite that provides an array of system components for Linux operating systems. The main aim is to unify service configuration and behavior across Linux distributions. Its primary component is a "system and service manager" — an init system used to bootstrap user space and manage user processes. It also provides replacements for various daemons and utilities, including device management, login management, network connection management, and event logging. The name ''systemd'' adheres to the Unix convention of naming daemons by appending the letter ''d''. It also plays on the term "System D", which refers to a person's ability to adapt quickly and improvise to solve problems. Since 2015, the majority of Linux distributions have adopted systemd, having replaced other init systems such as SysV init. It has been praised by developers and users of distributions that adopted it for providing a stable, fast out-of-the-box solution for issues that had exi ...

NLnet Labs
NLnet Labs is a Dutch network research laboratory in Amsterdam, founded in 1999 by the board members of NLnet. NLNet Labs develops DNS-related software, such as NSD, Unbound, OpenDNSSEC and getDNS. History NLnet Labs originated from the NLnet Foundation. NLnet's core business is to support independent organisations and people that contribute to an open information society. For long term research projects, NLnet Labs was founded in 1999 by the board members of NLnet and Ted Lindgreen. One of the first activities was creating an implementation for DNSSEC. In 2001 the RIPE NCC asked NLnet Labs to write a DNS implementation geared especially to rootservers, but not containing any code of existing software. This marked the start of the development of NSD, the authoritative nameserver package. Other major projects include a validating caching resolver Unbound, and the OpenDNSSEC project. On 19 April 2023, NLnet Labs and the Internet Systems Consortium (ISC) sent a joint lette ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
