Smart ways to ensure a glitch-free live video streaming experience

Users today expect a live town hall streaming video session to offer the same viewing experience as an online soccer match. The reality, however, can be quite different. The inherent complexity of hosting a live video streaming session behind a corporate firewall with a single path to the internet is considerable. If the network is not architected properly, potential problems can multiply exponentially. Despite the well publicised streaming problems suffered by high-profile organisations, most companies neglect to optimise networks for live events. This paper examines the pain points that hinder an organisation's ability to provide a consistent, reliable and secure user experience, as well as common causes of failure, including: planning and assessment of network, audience, capacity and purpose; insight into best practices that detail what works and why; strategies for content recording, archiving and tracking; and aligning user needs with organisational, industry compliance requirements. Using quantifiable data, objective industry analysis, third-party expert commentary and real-world examples of failures and successes, the author makes the case for enterprise content management and distribution solutions. These platforms serve as a mechanism to manage networks and user experience on the day of the event, mitigate streaming lapses, as well as enable tracking and postevent archiving.

Cloud market analysis from customer perspective

Abstract: Cloud computing services are presenting very simple approaches to buy IT needs from various technology providers. Existing cloud computing services cover wide spectrum of items including infrastructure, platforms or different spectrum of business applications. The typical list of items which can be ordered from cloud services providers are disk storages, database storage, raw computing power and any other technology function or application such as CRM or ERP. There are a lot of ways that a business can benefit from by acquiring cloud computing services. Some of these benefits include but not limited to improvement of accessibility to the critical information in real time and place; data security; lessen company operational cost; provide regular updates; increased scalability, and many more. Cloud computing also allows a business to run any application without the traditional restrictions of being limited to the confines of the corporate firewall which can help improve collaboration with customers and partners who are also in the cloud. Presented paper summarizes results of survey including different market regions. The goal of the survey was to discover and identify trends in the data, to reveal new information and identify the difference between regions, behavior of customers and on top to determine requirements related to the future Cloud computing services business. The survey contributes to the Cloud computing services through the use of wide range of variables. This research can benefit a wide audience, ranging from educational personnel, students and institutions, also businesses and public organizations.

Zero Knowledge and Hash-Based Secure Access Control Scheme for Mobile RFID Systems

The integration of RFID technology and mobile smart device stimulates the daily increasing popularity of mobile RFID-based applications, which makes its way to become a new hot zone for research and development. The primary mitigation strategies of RFID systems are ensuring that all devices are behind the corporate firewall, and physically securing the network itself. But due to the portable nature of an RFID Mobile device, as well as the potential to use wireless or internet connections for communications, Mobile RFID systems have specific security concerns that need to be addressed. In this paper, an authentication protocol based on zero-knowledge protocol and hashing in mobile RFID environment is proposed which effectively achieves forward security with preventing replay, eavesdropping, and counterfeit tag attacks.

Trends in Firewall Configuration Errors: Measuring the Holes in Swiss Cheese

The first quantitative evaluation of the quality of corporate firewall configurations appeared in 2004, based on Check Point Firewall-1 rule sets. In general, that survey indicated that corporate firewalls often enforced poorly written rule sets. This article revisits the first survey. In addition to being larger, the current study includes configurations from two major vendors. It also introduces a firewall complexity. The study's findings validate the 2004 study's main observations: firewalls are (still) poorly configured, and a rule -set's complexity is (still) positively correlated with the number of detected configuration errors. However, unlike the 2004 study, the current study doesn't suggest that later software versions have fewer errors.
