DNSSEC: A Protocol towards securing the Internet Infrastructure
Unlike spam, worms, viruses, and phishing—all of which confront end users directly—infrastructure attacks occur outside their normal frame of reference and control. But attacks on the Domain Name System (DNS), an engine of the Internet infrastructure, appear to be increasing in length and severity, affecting DNS information associated with financial services institutions, Internet service providers, and major corporations in the travel, health, technology, and media/ entertainment sectors. Such attacks can result in, say, dropped or intercepted email messages or users unknowingly redirected to fraudulent sites where they inadvertently hand over personal information.The ultimate casualty in a serious infrastructure attack is public trust. The Internet technical community has responded to threats to the DNS infrastructure by developing the DNS Security Extensions (DNSSEC) protocol standard. DNSSEC-enabled systems run primarily in only a few early adoption and experimental zones.DNSSEC introduces security at the infrastructure level through a hierarchy of cryptographic signatures attached to DNS records. In the context of DNSSEC, users are assured that the source of the data is verifiable as the stated source, and the mapping of a name to an IP address is accurate. DNSSEC – capable name servers also provide denial of- existence; that is, they tell a user that a name does not exist.
Tizen is an operating system for multiple device categories including smartphones, tablets, in-vehicle infotainment (IVI) devices, smart TVs, and more. Tizen offers a consistent user experience that consumers can take from device to device. Tizen is open source and standards-based software. Its main components are the Linux kernel, the Enlightenment Foundation Libraries (EFL) and the WebKit runtime.The Tizen project resides within the Linux Foundation and is governed by a Technical Steering Group (TSG). The TSG (Intel and Samsung) is the primary decision-making body, with a focus on platform development and delivery, along with the formation of working groups to support device verticals.The Tizen Association has been formed to guide the industry role of Tizen, including gathering of requirements, identification and facilitation of service models, and overall industry marketing and education.Tizen provides a flexible environment for application developers, based on jQuery and jQuery Mobile. The software development kit (SDK) allows developers to use HTML5 and related web technologies to write applications that run across multiple device segment
