Chelmsford, MA (PRWEB) May 10, 2011
Arbor Networks, Inc., a leading provider of security and network management solutions for next-generation data centers and carrier networks, today announced the Arbor Pravail Availability Protection System (APS) appliances, a new product family focused on securing the Internet data center (IDC) edge from threats against availability specifically, protection against application-layer distributed denial of service (DDoS) attacks.
For more than a decade, Arbor Networks has developed innovative, market-leading DDoS detection and mitigation solutions that are deployed in the vast majority of the worlds largest and most valuable service provider networks. Arbor has leveraged this experience to create the Arbor Pravail APS, bringing carrier-class DDoS detection and mitigation capabilities to the data center, said Colin Doherty, Arbor Networks president. Pravail is purpose-built to address the number one threat to the availability of IDC resources application-layer DDoS attacks. This new product is squarely addressing a major concern for IDC operators and for those thinking about adopting a Cloud Computing model.
In recent months, high profile attacks and outages have gotten the attention of C-level executives, said Rob Ayoub, Global Program Director, Network Security at Frost & Sullivan. They are starting to understand that security begins with availability. If your data center is not available, all the compliance or data integrity in the world is not going to help your customers, business or your brand, said Ayoub. Arbor is addressing the number one threat to the availability of data center resources and that is the increasing prevalence and effectiveness of application-layer denial of service attacks that target infrastructure, and potentially, existing security devices themselves.
While key elements of an overall security strategy, firewalls and Intrusion Prevention Systems are not effective solutions against DDoS attacks. Because these devices maintain state information for every session established between a client on the Internet and the corresponding server in the data center, these products themselves are commonly the targets of DDoS attacks. According to Arbors 2010 Worldwide Infrastructure Security Report, a solid majority of those who have deployed these devices within their IDCs experienced stateful firewall and/or IPS failure as a direct result of DDoS attacks during the survey period. Arbor Pravail APS is a purpose-built platform to identify and block application-layer DDoS attacks that threaten IDC availability.
Arbor Pravail APS highlights:
Purpose-built for IDC deployment scenarios

???? -Automates the identification of botnet-borne attacks against data center infrastructure
???? -Updates for new threats are delivered automatically and also include geo-location data
Cloud Signaling
Arbors Pravail APS Cloud Signaling capability helps to ensure the availability of IDC infrastructures and speed time-to-mitigation for DDoS attacks. Arbor believes that the only way for IDC and Cloud operators to have optimal protection against DDoS attacks is through a combination of on-premise and in-cloud protection. Working with its Internet service provider (ISP) and managed security services provider (MSSP) customers, Arbor has developed a protocol to facilitate both customer edge mitigation of application-layer attacks and upstream mitigation of volumetric attacks in an automated and real-time manner. Cloud Signaling is an efficient and integrated system bridging the customer premise to the service provider cloud.
Carrier-class Detection and Mitigation for the IDC
Application-layer DDoS attacks have quickly become the most significant threat to availability of IDC and Cloud-based services. Application-layer attacks are low bandwidth, difficult to detect and target both end customers and network operators own ancillary supporting services, such as HTTP Web services, domain name system (DNS), etc. The Arbor Pravail APS provides visibility into critical IP services and applications running in the IDC, such as HTTP, DNS, VoIP/SIP and SMTP traffic. The Arbor Pravail APS also protects IDC infrastructure against numerous types of attack, including TCP State Exhaustion, HTTP/Web Attacks, DNS Floods/Authentication Attacks, TCP SYN Floods, Spoofed / Non-Spoofed Attacks, UDP Floods and dozens more.
ATLAS Intelligence Feed
The Arbor ATLAS intelligence feed enables Pravail APS to provide unprecedented protection against botnet-fueled DDoS attacks. Over the past five years, Arbor has tracked the rise of botnet-fueled DDoS attacks — in this years Worldwide Infrastructure Security Report, botnets were identified as the primary engine fueling DDoS attacks that threaten the availability of data center and cloud-based infrastructures. Arbor has unique visibility into DDoS botnets because of its ATLAS infrastructure, which combines a darknet sensor network with traffic data from more than 100 service provider customers around the world.
This enormous dataset enables Arbors security researchers to develop a unique, globally-scoped view of malicious traffic traversing backbone networks that form the Internet’s core. This insight is critical, as botnets are constantly changing and updating to thwart detection. The new ATLAS Intelligence Feed delivers deep DDoS signatures in real time to keep the data center edge protected against hundreds of botnet-fueled DDoS attack toolsets and their variants. Moreover, this new feed includes geo-location data and automates the identification of attacks against data center infrastructure and services from known botnets while ensuring that updates for new threats are automatically delivered without software upgrades. Arbor’s researchers are constantly analyzing DDoS botnet attacks–more than 4,300 to date. The ATLAS Intelligence Feed enables customers to directly benefit from the depth and breadth of Arbors research team.

Whitby, Ontario (PRWEB) January 14, 2012
Campkins RV Centre, serving southern Ontario in Canada, reports a very strong Fall Selling Season and attributes it to Overwhelming Internet Traffic. 2011 was the companys very best year since it started in 1973.
Campkins RV uses a combination of Search Engine Optimization and online and traditional marketing techniques. The most important tactic, according to Owner and Sales Manager Brad Campkin, has been ensuring that ALL of their New RVs and Used RVs are being advertised, through multiple channels, with detailed descriptions, lots of pictures and posted pricing. Our SEO/Web partner, SynergyPro Solutions, makes sure each product page has the best chance of being indexed by Google and the other search engines.
Campkins RV website traffic surpassed one million inventory page views for the very first time. Going from approximately 350,000 in 2010 to over a million in 2011 definitely has kept our sales department much busier, in fact weve even had to hire two more sales people to keep up, says Brad.
Traffic is a great barometer of your companys online health but conversion rates are the true indicator of fitness. The Campkins RV Centre conversion rate is higher than ever – We track each contact made and are seeing just under 50% of our calls and emails from the website converting to visits at the dealership! Campkin also says having the SELLING PRICE on the website, not Call for Price or fill out a form to get the price has made a huge difference. People come in knowing what to expect and are all set to look at the RVs they saw online, he says.
New this past year, Campkins launched Canadas first RV Parts and Accessory Store. Many dealership Parts & Accessory offerings are just a link to a third party suppliers online catalogue. Campkins RV has created an RV Parts Store that lists the actual inventory in their Accessory Showroom and allows customers to place orders and pay by credit card instantly. We have made it easy for our customers to shop online, again making our Website our most important marketing tool year-round, says Brad. The future is here and we embrace it!
We have also created a Mobile Website for Smart-phones and Tablets so that when our customers are on the go on the road in their RVs, they can access our Parts and Accessory Store right from their mobile devices, they can book a service appointment, locate or call us with a click of a button, plus all our inventory in stock is accessible from our mobile website.
Last but not least Campkins RV Centre has an iPhone App, available on the iTunes Store, that is really quite popular. Brad says We are getting a lot of new subscribers who now receive our push notifications of daily news and events at the dealership, up-to-the-minute specials, clearance pricing and much more.
You can follow Campkins RV on Twitter or join them on Facebook. Find all the links on their website: http://www.campkins.com
