DDoS, the abbreviation of “Distributed Denial-of-Service”, is a malicious attempt against websites, servers, or networks unavailable to provide its services or resources to its intended users. Usually, targets of DDoS are high-profile sites such as government agencies, giant corporations, financial institutions, major cloud service providers, telecommunication businesses, and politically related groups. The following article will discuss the background and types of DDoS attacks, and also get into the methods of prevention and protection.
With the rapid rise of BYOD (Bring Your Own Device) phenomenon contributed by the widespread of smart mobile devices, the increasing implementations of wireless accessing points (APs) in corporate environments have become an attraction for potential network intrusion and data theft. As software-based measures have been found with numerous loopholes, corporations have to rely on hardware-assistance for total solution in BYOD environment. The following will discuss the BYOD situations in details and present a hardware-assisted total solution with multiple advantages including Intel x86 firewall architecture and high-port density, which are optimally deployable for BYOD settings.
With the exponential growth of mobile Internet devices and the rise of Cloud Computing, end-users demand faster, more powerful and more secured Internet services. This unprecedented demand has presented a new challenge which Internet service provider and IT system operators maintain and manage their network traffic. To ensure smooth network traffic, an all new enhanced architecture is necessary in order to handle the various types of data packets and security instructions. In other words, performance, power efficiency, scalability and reliability are the major factors in network traffic management.
In an era where high speed networks are affordable and readily available, video streaming in high quality over IP has replaced the costly video broadcasting over analog or lease lines as a more flexible and cost-effective solution. Compare with regular data transmission, stricter requirements must be met for streaming broadcast-level video over an open Internet, where uneven deliveries, packet loss and buffering are unacceptable. For high quality video broadcast services such as video on demand (VOD) and over the top (OTT), user experience very much depends on continuous and seamless packet delivery over an open Internet.
In order to provide access to data on any device at locations such as stadiums, shopping centers and medium-sized branch offices as well as campuses, content providers and telecom companies are required to build their information superhighways on both wired and wireless networks that deliver enterprise-scale capacity, stringent performance and reliability.
Generally speaking, the term “x86 servers” refers to computing systems that are based on Intel architecture, which is widely adopted by manufacturers due to its backward compatibility with instruction sets and scalability. This compatibility allows software reuse across generations of products, protecting the software investment, while the scalability satisfies demand for throughput and workloads. Although many servers built on the Intel architecture share the same hardware components and functionality, the varied uses and designs for these servers call for unique features that allow them to fulfill their intended purposes.
Network security measures deployed across most of today’s enterprise network architecture usually involve SSL, data compression, VPNs or a combination of either three. SSL, or Secure Socket Layer, is used for information encryption; data compression, on the other hand, ensures bandwidth efficiency and increases WAN throughput while VPNs, or Virtual Private Networks, allow for cost-effective and secure remote access to private networks. Regardless of which security measures are eventually implemented, hardware/software integration must first be optimized and streamlined in order to support security functions’ computationally intensive algorithms.
