Virtual private network

Virtual private network
VPN connectivity overview A virtual private network connection across the Internet is similar to a wide area network (WAN) link between sites. From a user perspective, the extended network resources are accessed in the same way as resources available within the private network.[2] VPNs allow employees to securely access their company's intranet while traveling outside the office. Similarly, VPNs securely connect geographically disparate offices of an organization, creating one cohesive network. VPN technology is also used by Internet users to connect to proxy servers for the purpose of protecting personal identity and location. Types[edit] Early data networks allowed VPN-style remote connectivity through dial-up modems or through leased line connections utilizing Frame Relay and Asynchronous Transfer Mode (ATM) virtual circuits, provisioned through a network owned and operated by telecommunication carriers. VPN systems may be classified by: Security mechanisms[edit] Authentication[edit]

Open-source software Open-source software (OSS) is computer software with its source code made available and licensed with a license in which the copyright holder provides the rights to study, change and distribute the software to anyone and for any purpose.[1] Open-source software is very often developed in a public, collaborative manner. Open-source software is the most prominent example of open-source development and often compared to (technically defined) user-generated content or (legally defined) open-content movements.[2] A report by the Standish Group (from 2008) states that adoption of open-source software models has resulted in savings of about $60 billion per year to consumers.[3][4] Definitions[edit] The Open Source Initiative's (OSI) definition is recognized[who?]

At a Cafe? I Can Hack Your Facebook, Twitter, Etc...With a Firefox Extension Whenever you connect to an unsecured WiFi network, you're taking a chance, but now it's easier than ever for someone to gain access to all of your social network login information. A new Firefox extension called Firesheep makes it simple for anyone to see that you're connected to the network, grab your login information for any number of social networks, and take over your online identity. Without this, hacking your account over an unsecured wireless network may not be rocket science, but it surely isn't the one-click magic made possible by Firesheep.

In computing, a firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic by analyzing the data packets and determining whether they should be allowed through or not, based on applied rule set. A firewall establishes a barrier between a trusted, secure internal network and another network (e.g., the Internet) that is not assumed to be secure and trusted.[1] Firewall technology emerged in the late 1980s when the Internet was a fairly new technology in terms of its global use and connectivity.

Emacs Releases | Supported Platforms | Obtaining Emacs | Documentation | Support | Further information GNU Emacs is an extensible, customizable text editor—and more. At its core is an interpreter for Emacs Lisp, a dialect of the Lisp programming language with extensions to support text editing. Uniform resource name A uniform resource identifier (URI) is a uniform resource locator (URL), uniform resource name (URN), or both. Since RFC 3986 in 2005, the use of the term has been deprecated in favor of the less-restrictive "URI", a view proposed by a joint working group between the World Wide Web Consortium (W3C) and Internet Engineering Task Force (IETF). Both URNs and uniform resource locators (URLs) are URIs, and a particular URI may be a name and a locator at the same time. URNs were originally intended in the 1990s to be part of a three-part information architecture for the Internet, along with URLs and uniform resource characteristics (URCs), a metadata framework. However, URCs never progressed past the conceptual stage, and other technologies such as the Resource Description Framework later took their place.

EAP Authentication with RADIUS Server Introduction This document provides a sample configuration of a Cisco IOS® based access point for Extensible Authentication Protocol (EAP) authentication of wireless users against a database accessed by a RADIUS server. Due to the passive role that the access point plays in EAP (bridges wireless packets from the client into wired packets destined to the authentication server, and vice versa), this configuration is used with virtually all EAP methods. These methods include (but are not limited to) LEAP, Protected EAP (PEAP)-MS-Challenge Handshake Authentication Protocol (CHAP) version 2, PEAP-Generic Token Card (GTC), EAP-Flexible Authentication via Secure Tunneling (FAST), EAP-Transport Layer Security (TLS), and EAP-Tunneled TLS (TTLS). You must appropriately configure the authentication server for each of these EAP methods. This document covers how to configure the access point (AP) and the RADIUS server, which is Cisco Secure ACS in the configuration example in this document.

10 Tips for Powerful Emacs on Windows I avoided using Microsoft Windows for almost 15 years, but with my new job at a Microsoft-enthralled development shop, those idyllic days have come to an abrupt end. Because in the past I could always use my trusty Linux and OS X machines, I never did push past the hurdles of using Emacs on Windows. My utter reliance on Org-mode, TRAMP, and Ediff (to name a few) made it essential to get Emacs working on Windows if at all possible.

Peer-to-peer file sharing Peer-to-peer file sharing is the distribution and sharing of digital documents and computer files using the technology of peer-to-peer (P2P) networking. P2P file sharing allows users to access media files such as books, music, movies, and games using a specialized P2P software program that searches for other connected computers on a P2P network and locates the desired content.[1] The nodes (peers) of such networks are end-user computer systems that are interconnected via the Internet. Several factors contributed to the widespread adoption and facilitation of peer-to-peer file sharing. These included increasing Internet bandwidth, the widespread digitization of physical media, and the increasing capabilities of residential personal computers.

World’s First Computer Rebuilt, Rebooted After 2,000 Years A British museum curator has built a working replica of a 2,000-year-old Greek machine that has been called the world’s first computer. A dictionary-size assemblage of 37 interlocking dials crafted with the precision and complexity of a 19th-century Swiss clock, the Antikythera mechanism was used for modeling and predicting the movements of the heavenly bodies as well as the dates and locations of upcoming Olympic games. The original 81 shards of the Antikythera were recovered from under the sea (near the Greek island of Antikythera) in 1902, rusted and clumped together in a nearly indecipherable mass.

OpenVPN OpenVPN has been ported and embedded to several systems. For example, DD-WRT has the OpenVPN server function. SoftEther VPN, a multi-protocol VPN server, has an implementation of OpenVPN protocol. Architecture[edit] Security Index Reveals Most Americans Support Internet “Kill Switch” As National Security Remains Top Overall Concern BLUE BELL, Pa. – October 27, 2010 –Sixty-one percent of Americans said the President should have the ability to shut down portions of the Internet in the event of a coordinated malicious cyber attack, according to research conducted in August by Unisys Corporation (NYSE: UIS). The Unisys survey also found that while Americans are taking proactive steps to protect themselves against cyber crime and identity theft, only slightly more than a third of Internet users in the U.S. regularly use and update passwords on their mobile devices – creating a potentially huge security hole for organizations as more consumer devices invade the workplace. The findings, part of the latest bi-annual Unisys Security Index, illustrate that recent events such as the Stuxnet computer worm attack and the attempted Times Square car bombing may have heightened the American public’s awareness of and concern over global and domestic cybersecurity threats.
