The demand for higher-level security has been the driving force for the populated installations of surveillance cameras in mission-critical environments, such as airports, banks, public transits, and state-owned institutions, and IP cameras are the preferred choice over conventional CCTV types due to ease of deployments. However, when there are saturated amount of IP cameras, there are perhaps billions of video data captured by these surveillance devices on a daily basis. This will definitely cause latency for video analytics, when IP cameras transfer the captured videos through Internet protocols.

Due to the rapid evolution of cyber attacks, businesses and organizations across the world, no matter large or small scale, are exposed to extremely high risks of data security threats. The recent widespread of ransomware attacks has disrupted operations and profitability to many corporations and institutions. According to statistics, the top three victimized countries are United States, Taiwan and Japan. Recently, even well-known religious organizations and hospitals in Taiwan have been attacked by ransomware. In 2016 alone, experts have determined the most infamous global ransomware attacks: CryptoWall, Locky and Cerber, each accounted for approximately 41%, 34% and 24% respectively.

Maintaining the network availability has been the top priority for enterprises worldwide, as virus attacks have intensified in size, frequency and complexity. In fact, service providers have been unprecedentedly sensitive for their network protection since the first incident of DDoS attacks, which cause Internet outage and severe damage to the serviceability of network infrastructure of the victimized service providers, namely GitHub and Sony.

Data breaches are usually intentional leaks of information without authorization, normally by hacking actions. Data breaches are destructive nightmares to major corporations and organizations because it severely damages not only their profitability, but also trust and reputations. Victims are usually giant corporations or organizations with huge base of users or member, which means gigantic amount of data as the target for hackers. In fact, some user or member data are highly sensitive or confidential and this will severely ruin the serviceability and reliability of the service providers.

The massive DDoS attack on Dynamic Network Service (Dyn) which caused severe network outages and disruptions to Dyn’s major clients including Twitter, Raddit, Spotify, Tumblr, and many other well-known websites. When a DDoS attack penetrates its targeted service website, users of the victimized site may experience disruptions or outages when accessing the services and functions. The crisis was regarded as a loud wake-up call on how vulnerable our cloud services and data centers are in terms of DDoS attack.

Over the past 15 years we've witnessed a gradual change in branch WANs requirements. Whereas most branch offices, more often than not, were connected to the rest of the business through an MPLS circuit or VPN, we are seeing more and more network architectures being updated either by way of increasing more capacity to the existing WAN circuit or by introducing an Internet connection to the branch WAN.

SD-WAN is becoming the most anticipated WAN Services today. According to the latest Gartner Report on WAN Edge Infrastructure, in next 5 years more than 90% of WAN edge infrastructure will be based on vCPE platform or SD-WAN versus traditional router for managing network connectivity and resources from distributed branches to data center and the cloud.
