Clickjacking
Clickjacking (classified as a user interface redress attack or UI redressing) is a malicious technique of tricking a user into clicking on something different from what the user perceives, thus potentially revealing confidential information or allowing others to take control of their computer while clicking on seemingly innocuous objects, including web pages. Clickjacking is an instance of the confused deputy problem, wherein a computer is tricked into misusing its authority.The Confused Deputy rides again!

Confused Deputy Problem
In information security, a confused deputy is a computer program that is tricked by another program (with fewer privileges or less rights) into misusing its authority on the system. It is a specific type of privilege escalation. The confused deputy problem is often cited as an example of why capability-based security is important. Capability systems protect against the confused deputy problem, whereas access control list-based systems do not. Example In the original example of a confused deputy, there was a compiler program provided on a commercial timesharing service. Users could run the compiler and optionally specify a filename where it would write debugging output, and the compiler would be able to write to that file if the user had permission to write there. The compiler also collected statistics about language feature usage. Those statistics were stored in a file called "(SYSX)STAT", in the directory "SYSX". To make this possible, the compiler program was given permissi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Browser
A web browser is application software for accessing websites. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers are used on a range of devices, including desktops, laptops, tablets, and smartphones. In 2020, an estimated 4.9 billion people used a browser. The most used browser is Google Chrome, with a 65% global market share on all devices, followed by Safari with 18%. A web browser is not the same thing as a search engine, though the two are often confused. A search engine is a website that provides links to other websites. However, to connect to a website's server and display its web pages, a user must have a web browser installed. In some technical contexts, browsers are referred to as user agents. Function The purpose of a web browser is to fetch content from the World Wide Web or from local storage and display it on a user's device. This process ...

Password Synchronization
Password synchronization is a process, usually supported by software such as password managers, through which a user maintains a single password across multiple IT systems. Provided that all the systems enforce mutually-compatible password standards (e.g. concerning minimum and maximum password length, supported characters, etc.), the user can choose a new password at any time and deploy the same password on his or her own login accounts across multiple, linked systems. Where different systems have mutually incompatible standards regarding what can be stored in a password field, the user may be forced to choose more than one (but still fewer than the number of systems) passwords. This may happen, for example, where the maximum password length on one system is shorter than the minimum length in another, or where one system requires use of a punctuation mark but another forbids it. Password synchronization is a function of certain identity management systems and it is considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Attack (computing)
A cyberattack is any offensive maneuver that targets computer information systems, computer networks, infrastructures, or personal computer devices. An attacker is a person or process that attempts to access data, functions, or other restricted areas of the system without authorization, potentially with malicious intent. Depending on the context, cyberattacks can be part of cyber warfare or cyberterrorism. A cyberattack can be employed by sovereign states, individuals, groups, societies or organisations and it may originate from an anonymous source. A product that facilitates a cyberattack is sometimes called a cyber weapon. Cyber attacks have increased with an alarming rate for the last few years A cyberattack may steal, alter, or destroy a specified target by hacking into a susceptible system. Cyberattacks can range from installing spyware on a personal computer to attempting to destroy the infrastructure of entire nations. Legal experts are seeking to limit the use of the ter ...

URL Redirection
URL redirection, also called URL forwarding, is a World Wide Web technique for making a web page available under more than one URL address. When a web browser attempts to open a URL that has been redirected, a page with a different URL is opened. Similarly, domain redirection or domain forwarding is when all pages in a URL domain are redirected to a different domain, as whewikipedia.comanwikipedia.netare automatically redirected twikipedia.org URL redirection is done for various reasons: * for URL shortening; * to prevent broken links when web pages are moved; * to allow multiple domain names belonging to the same owner to refer to a single web site; * to guide navigation into and out of a website; * for privacy protection; and * for hostile purposes such as phishing attacks or malware distribution. Purposes There are several reasons to use URL redirection: Forcing HTTPS A website may potentially be accessible over both a secure HTTPS URI scheme and plain HTTP (an insecur ...

Framing (World Wide Web)
In the context of a web browser, a frame is a part of a web page or browser window which displays content independent of its container, with the ability to load content independently. The HTML or media elements shown in a frame may come from a different web site as the other elements of content on display, although this practice, known as framing, is today often regarded as a violation of same-origin policy. In HTML, a frameset is a group of named frames to which web pages and media can be directed; an iframe provides for a frame to be placed inside the body of a document. Since the early 2000s, the use of framesets has been considered obsolete due to usability and accessibility concerns, and the feature has been removed from the HTML5 standard. Tags and attributes The frames in HTML are created using the tag pair. The tag is a container tag for all other tags that are used to create frames. The tag replaces the tag in frameset documents.The tag defines how to divide t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Password Manager
A password manager is a computer program that allows users to store and manage their passwords for local applications and online services. In many cases software used to manage passwords allow also generate strong passwords and fill forms. Password manager can be delivered as a one of or mixed of: computer application, mobile application, web browser extension, web based service, portable software for USB units. A password manager assists in generating and retrieving complex passwords, storing such passwords in an encrypted database, or calculating them on demand. Depending on the type of password manager used and on the functionality offered by its developers, the encrypted database is either stored locally on the user's device or stored remotely through an online cloud storage. Password managers typically require a user to generate and remember one "master" password to unlock and access information stored in their databases. Modern password managers increase security usi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pop-up Notification
The pop-up notification (or toast, passive pop-up, snackbar, desktop notification, notification bubble, or simply notification) is a graphical control element that communicates certain events to the user without forcing them to react to this notification immediately, unlike conventional pop-up windows. Desktop notifications usually disappear automatically after a short amount of time. Often their content is then stored in some widget that allows the users to access past notifications at a more convenient time. On mobile devices, a push notification system is typically used. Support on different systems In Windows 2000, Microsoft introduced balloon help-like passive pop-up notifications, tied to the notification area of the task bar. Notifications get queued when user is away or screensaver is running, and get shown when the user resumes activity. They remain on screen for nine seconds while fading out if the user appears to ignore them. Microsoft also adopted similar notific ...

Android Devices
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablet computer, tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary.
