During a DDoS attack, the re-direction of traffic in the cloud comes in two varieties: DNS redirect (for application layer protection) and BGP redirect (for network/transport layer protection). Redirecting Traffic via DNS Domain Name Servers (DNS) … [Read more...] about Cloud Protection: DNS Redirect vs. BGP Redirect
While there are many advantages to cloud-based DDoS scrubbing, which filters malicious traffic from legitimate, there are several disadvantages as well. These include: - Scrubbing centers are only able to monitor inbound traffic - As outbound … [Read more...] about What are the Disadvantages to Cloud-based DDoS Scrubbing?
Cloud-based scrubbing employs separate DDoS traffic-cleaning engines to ‘scrub’ clean traffic, filtering bad from good. It is essentially used as an additional layer of protection during a DDoS attack rather than a primary mitigation … [Read more...] about What is Cloud-based DDoS Scrubbing?
There are five general requirements to remove an attack in the cloud: (i) Detect the attack asap and determine its size; (ii) Attempt to mitigate its effects as much as is possible; (iii) Migrate the Virtual Machine (VM), which is under attack to … [Read more...] about DDoS Mitigation in the Cloud: Part II
DDoS mitigation in the cloud presents a new dimension to solutions offered in traditional computing environments. By its very nature, cloud computing is vulnerable to DoS and DDoS attacks, however, it also offers many opportunities to recover quickly … [Read more...] about DDoS Mitigation in the Cloud: Part I
There are various mitigation techniques specifically to guard against the most destructive kinds of DDoS attacks in the cloud: XML and HTTP-DoS attacks. Filtering Tree The XML consumer request is changed into a tree form and uses a virtual … [Read more...] about Mitigating Against XML and HTTP-DoS and DDoS Attacks
XML and HTTP DoS or DDoS attacks both aim to exhaust server resources. EXtensible Markup Language (XML) and HyperText Transfer Protocol (HTTP) are both used extensively in cloud computing web services. Not very much work has been done to ensure … [Read more...] about XML-DoS and HTTP-DoS Attacks in the Cloud
Cloud computing allows on-demand access to a shared pool of resources, including networks, servers, storage and services. DoS and DDoS attacks are serious threats to the availability of services offered on the cloud because of the various new … [Read more...] about DDoS Attacks in Cloud Computing
