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] |
Data Breach
A data breach, also known as data leakage, is "the unauthorized exposure, disclosure, or loss of personal information". Attackers have a variety of motives, from financial gain to political activism, political repression, and espionage. There are several technical root causes of data breaches, including accidental or intentional disclosure of information by insiders, loss or theft of unencrypted devices, hacking into a system by exploiting software vulnerabilities, and social engineering attacks such as phishing where insiders are tricked into disclosing information. Although prevention efforts by the company holding the data can reduce the risk of data breach, it cannot bring it to zero. The first reported breach was in 2002 and the number occurring each year has grown since then. A large number of data breaches are never detected. If a breach is made known to the company holding the data, post-breach efforts commonly include containing the breach, investigating its scope ...

Google Allo
Google Allo was an instant messaging mobile app by Google for the Android (operating system), Android and iOS mobile operating systems, with a web client available in some web browsers. It closed on March 12, 2019. The app used phone numbers as identifiers, allowing users to exchange messages, files, voice notes, and images. It included a Virtual assistant (artificial intelligence), virtual assistant that generated automatic reply suggestions and an optional encrypted mode known as incognito mode. Users could also resize messages and add doodles and stickers on images before sending them. Before launch, Google touted strong privacy in the app, with particular emphasis on messages stored "transiently and in non-identifiable form". However, at launch, privacy was significantly rolled back, with Google keeping logs of messages indefinitely (or until the user deletes messages) in an effort to improve the app's "smart reply" feature. History Allo was announced at Google's Google I/O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hushmail
Hushmail is an encrypted proprietary web-based email service offering PGP-encrypted e-mail and vanity domain service. Hushmail uses OpenPGP standards. If public encryption keys are available to both recipient and sender (either both are Hushmail users or have uploaded PGP keys to the Hush keyserver), Hushmail can convey authenticated, encrypted messages in both directions. For recipients for whom no public key is available, Hushmail will allow a message to be encrypted by a password (with a password hint) and stored for pickup by the recipient, or the message can be sent in cleartext. In July 2016, the company launched an iOS app that offers end-to-end encryption and full integration with the webmail settings. The company is located in Vancouver, British Columbia, Canada.

Lavabit
Lavabit is an open-source encrypted webmail service, founded in 2004. The service suspended its operations on August 8, 2013, after the U.S. Federal Government ordered it to turn over its Secure Sockets Layer (SSL) private keys, in order to allow the government to spy on Edward Snowden's email.Edward Snowden’s E-Mail Provider Defied FBI Demands to Turn Over Crypto Keys, Documents Show ''Wired'' Lavabit's owner and operator, Ladar Levison, announced on January 20, 2017, that Lavabit would start operating again, using the new Dark Internet Mail Environment (DIME), which is an end-to-end |
Client (computing)
is a computer that gets information from another computer called server in the context of client–server model of computer networks. The server is often (but not always) on another computer system, in which case the client accesses the service by way of a network. A client is a program that, as part of its operation, relies on sending a request to another program or a computer hardware or software that accesses a service made available by a server (which may or may not be located on another computer). For example, web browsers are clients that connect to web servers and retrieve web pages for display. Email clients retrieve email from mail servers. Online chat uses a variety of clients, which vary on the chat protocol being used. Multiplayer video games or online video games may run as a client on each computer. The term "client" may also be applied to computers or devices that run the client software or users that use the client software. A client is part of a cl ...

Server (computing)
A server is a computer that provides information to other computers called " clients" on a computer network. This architecture is called the client–server model. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients or performing computations for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. Client–server systems are usually most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgment. Designating a computer as "server-class hardwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Man-in-the-middle Attack
In cryptography and computer security, a man-in-the-middle (MITM) attack, or on-path attack, is a cyberattack where the attacker secretly relays and possibly alters the communications between two parties who believe that they are directly communicating with each other, where in actuality the attacker has inserted themselves between the two user parties. One example of a MITM attack is active eavesdropping, in which the attacker makes independent connections with the victims and relays messages between them to make them believe they are talking directly to each other over a private connection, when in fact the entire conversation is controlled by the attacker. In this scenario, the attacker must be able to intercept all relevant messages passing between the two victims and inject new ones. This is straightforward in many circumstances; for example, an attacker within range of a Wi-Fi access point hosting a network without encryption could insert themselves as a man in the middle. ...

Terrestrial Trunked Radio
Tetra is the common name of many small freshwater characiform fishes. Tetras come from Africa, Central America, and South America, belonging to the biological families Characidae, Alestidae (the "African tetras"), Lepidarchidae, Lebiasinidae, Acestrorhynchidae, Stevardiidae, and Acestrorhamphidae. In the past, all of these families were placed in the Characidae. The Characidae and their allies are distinguished from other fish by the presence of a small adipose fin between the dorsal and caudal fins. Many of these, such as the neon tetra (''Paracheirodon innesi''), are brightly colored and easy to keep in captivity. Consequently, they are extremely popular for home aquaria. ''Tetra'' is no longer a taxonomic, phylogenetic term. It is short for '' Tetragonopterus'', a genus name formerly applied to many of these fish, which is Greek for "square-finned" (literally, four-sided-wing). Because of the popularity of tetras in the fishkeeping hobby A hobby is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endpoint Security
Endpoint security or endpoint protection is an approach to the protection of computer networks that are remotely bridged to client devices. The connection of endpoint devices such as laptops, tablets, mobile phones, and other wireless devices to corporate networks creates attack paths for security threats. Endpoint security attempts to ensure that such devices follow compliance to standards. The endpoint security space has evolved since the 2010s away from limited antivirus software and into more advanced, comprehensive defenses. This includes next-generation antivirus, threat detection, investigation, and response, device management, data loss prevention (DLP), patch management, and other considerations to face evolving threats. Corporate network security Endpoint security management is a software approach that helps to identify and manage the users' computer and data access over a corporate network. This allows the network administrator to restrict the use of sensitive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
