Security: Experts warn on Java 6 Vulnerability

Posted by Unknown | August 27, 2013 |

Oracle released Java 7 update 25 in June 2013, while admitting the Java Runtime Environment (JRE) bug (CVE-2013-2463) in the later version, Java 6 and advised that users should upgrade to the most recent version. Now, security experts within last few days have uncovered an active exploitation of the vulnerability in Java 6 "Proof of Concept for CVE-2013-2463" attack code to compromise users systems.

The Neutrino crimeware kit which was first uncovered in March 2013, seems to be the point of exploit for the vulnerability according to security analyst, Timo Hirvonen of F-Secure.

The mode of attack include exploitation of Java vulnerability to install ransomeware on users PC, while such users are coaxed into paying some fines citing law enforcement agents involvement among others. The bug could be "exploited by malicious local users to disclose certain sensitive information, manipulate certain data, and gain escalated privileges and by malicious people to conduct spoofing attacks, disclose certain sensitive information, manipulate certain data, cause a DoS(denial of service), bypass certain security restrictions, and compromise a vulnerable system," according to Secunia.

Java 6 was officially retired in February, which is more reason the company did not make available a patch for it, but instead, recommend that users should upgrade to Java 7. Albeit, almost 48% of all Java users in the U.S. are still stuck to Java 6 according to statistics released March, 2013.

The ubiquity of the internet has strongly influenced modern communication systems, with VoIP (Voice over Internet Protocol) haven hitherto exerted enormous pressure on traditional communication players (Telcos), and the competition is even now fiercest as the new technology, WebRTC is gaining traction on the web.

WebRTC (Web-based Real-time Communication) is an open-source project (of course, free) that enables browser-to-browser applications with real-time communication capabilities through simplified JavaScript APIs without plug-ins.

The prototype comprises codes that Google open sourced  in May 2011, and followed by an ongoing work to standardized the relevant protocols in the IETF and browsers APIs in the W3C. The implementation revolves on works on HTML5 and related technologies supported by the Web Hypertext Application Technology Working Group (WHATWG). The project is supported by Google, Mozilla and Opera, increasingly spreading amongst other major web technology vendors.

Google is equally responsible for the key voice and video codecs WebRTC currently support - VP8 (video), iSAC (wide-band links) and iLBC (narrower connections).

What does all these mean? It won't be long after the point of aligning to standards for developers to start building applications into web-pages for voice and video calls. Albeit, such capabilities are possible already, but are specific to vendors implementing them. What WebRTC does is open the technology to all, not just to vendors that can afford to license a proprietary system.

Now, the revolutionary drive behind WebRTC is that ordinary Web developers using just JavaScript APIs can build fully functioning voice, video and data collaboration applications or have same embed within other applications or website with just a few lines of code.

The new technology, WebRTC will make voice and video call enabled web pages pervasive, with no plug-ins to download and install that may not be compatible with all the browsers you use, on the desktop or on your mobile devices. And that may ultimately be the future of voice and video calls for all.

Special Report: VoIP for Beginners

Posted by Unknown | August 07, 2013 |

VoIP (voice over Internet Protocol) is basically the transmission of  voice communications and multimedia sessions via internet protocol (IP) networks, for instance the web. While early VoIP service providers offered business model on the architecture of legacy telephone network, the modern generation providers (i.e Skype) have built closed networks offering the benefit of free calls with minimal charges on access to other communication networks.

The system employs session control and signaling protocols to control signaling and setup of calls. But, instead of being transmitted over a circuit-switched network, however, the digital information is packetized and transmitted as Internet Protocol (IP) packets over a packet-switched network.

And the pros of VoIP services includes being less expensive than standard telephone network services. But call quality can be a factor in one's decision to switch to VoIP. Albeit, constant innovation and upgrades are making VoIP comparable in quality to the traditional phone system.

In this whitepaper, VoIP for Beginners, you'll be introduced to how VoIP works. Along the lines of the key technical terms and learn the issues that affect bandwidth and call quality. Also, learn three issues to consider when defining VoIP call quality. Download the Free whitepaper on "VoIP for Beginners" now!
