Two new videos featured on the SDNCentral Juniper Channel discuss how enterprises and operators alike can potentially mitigate distributed denial-of-service (DDoS) attacks and, separately, significantly improve user experience for video streaming and large file downloads inside enterprise VPNs.
The first video addresses the emerging threat of low-and-slow application-layer attacks, which can be much harder to detect and mitigate than DDoS volumetric attacks. It addresses the questions plaguing so many enterprises and operators: How can anti-DDoS technology detect and mitigate both volumetric and low-and-slow attacks? What can organizations do to block malicious traffic and assure the high availability of critical resources — all while preventing the theft of valuable corporate assets?
This video depicts how the DDoS Secure service analyzes traffic flow and responds with real-time protection. By dropping suspect or non-compliant packets, as soon as the optimum performance from critical resources begins to degrade, the solution is positioned to support the high availability of critical resources while preventing the theft of valuable corporate assets.
The demo explains how DDoS Secure can be dynamically provisioned through Contrail to protect a web server from volumetric attacks and slow attacks targeting the application level. It describes how provisioning DDoS Secure with Contrail Protection can be used to protect a web server without restricting where that service can be deployed. This means that provisioning is more automated, and new services can be deployed on demand. It also enables service chaining of DDoS Secure to be run anywhere, in a data center or across data centers, or moved on demand.
The second video showcases Contrail as a platform that can dynamically provision a content delivery network (CDN) service. The solution tries to address the degradation users typically experience when streaming video and downloading large files inside enterprise VPNs.
As enterprises increasingly leverage multimedia and mobility technologies to communicate, educate, and share content, new security and regulatory concerns arise. Enterprises want to confine internal content within the boundary of an internal VPN, but content delivery over the WAN is challenging due to bandwidth constraints. This creates a significant challenge.
To solve the problem, some enterprises resort to public CDNs that cache content at locations near their offices. But this, too, brings challenges, as business-critical content needs to traverse outside the VPN. This can result in potential security risks and no SLA guarantee.
The demo explores how a CDN service can be dynamically configured through Contrail and configured using Amazon CloudFront APIs to facilitate enterprise-internal content delivery — without restricting where the service can be deployed. The video contrasts the user experience before and after the solution — from long, frequent jitter during streaming without any CDN to seamless streaming of video over a VPN through a CDN. With a step-by-step demonstration that shows dynamic CDN service running on Juniper Networks Contrail, the video presents an option that offers the security of a VPN without sacrificing performance.
