Malware and botnets such as ZeroAccess, Conficker and Storm need to be able to propagate and communicate. However, the fact that most organizations do not filter DNS queries means that it can be used as a covert communication channel. Data leaving a compromised system can be encoded in the DNS query and instructions can be sent back to the malware in the DNS responses without raising suspicions. This article gives an overview of this threat and describes some ways of protecting your network from it. DNS is a highly distributed system, i. These authoritative DNS servers only store data for their own domains and traversal of a number of authoritative DNS servers may be required to find a particular DNS record. When an application needs to lookup a DNS record, a query is sent to a local recursive resolver. This process is called recursive resolution and is usually handled by a fleet of resolvers within your infrastructure, or in this case, within the Azure infrastructure. The IP addresses of the recursive resolvers are either statically configured in the operating system by the network admin or dynamically configured through systems such as DHCP.
How did the event go?
What did we learn in the sessions?
The first Virtual Webmaster Unconference successfully took place on August 26th and, as promised, we'd like to share the main findings and conclusions here. As communicated before, this event was a pilot, in which we wanted to test a if there was an appetite for a very different type of event, and b whether the community would actively engage in the discussions. To the first question, we were overwhelmed with the interest to participate; it definitely exceeded our expectations and it gives us fuel to try out future iterations. Despite the frustration of many, who did not receive an invitation, we purposefully kept the event small. This brings us to our second point: it is by creating smaller venues that discussions can happen comfortably. Larger audiences are perfect for more conventional conferences, with keynotes and panels. The Virtual Webmaster Unconference, however, was created to hear the attendees' voices. And we did. In total, there were 17 sessions. We divided them into two blocks: half of them ran simultaneously on block 1, the other half on block 2.

Today we are releasing the ability to access Windows Azure Blobs using custom domain names. Windows Azure Blob storage enables applications to store and manipulate large objects and files in the cloud. The custom storage domain name feature allows you to register a custom domain name for a given storage account for anonymous blob access using that domain name.
The most recent source for. All domain name holders, registrars and Arnes as the registry are bound by it. This procedure is also quick and inexpensive way of resolving domain name disputes but it does not exclude the possibility of using other legal remedies. In case of a dispute independent arbiters are appointed to deliver a verdict with which Arnes must comply with. When the ADR is started both the complainant and domain holder must follow the proper procedure, use proper forms and mind the terms. We have prepared a graphic illustration of the procedure to offer you some help. Terms used Unless otherwise indicated by the text, the terms used in the ARDS Rules shall have the following meanings:.
