DNS is like the town gossip of the network infrastructure. Computers and apps ask DNS questions and you can ask DNS who has been asking to resolve malware domains. When internal trusted systems are using DNS to resolve the names of known malware sites, this can be an Indicator of Compromise and a warning to clean the potentially infected systems and block traffic to the domain.
Blacklisting the known malware domains using local RPZs, firewalls, Cisco IronPort Web Security Appliance (WSA), or Cloud Web Security (CWS) is a great way to add an extra level of security in organizations. But what if you are just getting started in the process of cleaning systems and just need some situational awareness? Or, how can you manually check to see if these devices are working as expected? How can you determine independently of security devices, and at any point in time, that client systems are not reaching out to malicious domains? You can use dig but this post focuses on a Python example. Let’s first take a look at some DNS mechanics.

Dude, where’s my IP?
I love to check in on social networks like Foursquare and Google+. Most of the time, there’s no point to it, but it’s fun to see what friends and colleagues are up to or discover new local haunts. Despite the fun and games, location is much more important to the network than it appears. My physical location may have little or everything to do with my network location and there’s no reason for them to match exactly, but there are significant reasons to be more accurate.

Guest post by Dennis Clark, Senior Solutions Marketing Manager -- Microsoft Applications, NetApp
We are here in Charlotte this week with our Cisco friends, with the opportunity to talk with all sorts of like-minded Microsoft SQL Server individuals at the 2013 SQL PASS Summit. The conversations vary in range from things like database performance, developer issues, to private cloud and data management concerns. We’ve also had some good chats with a few data warehouse folks, which prompted me to share some thoughts on this topic.
We know that the data warehouse (DW) is central to a comprehensive business intelligence (BI) solution. So clearly, if our DW isn’t up to snuff, as they say, then we can forget about delivering critical analytics to a growing number of LOB managers and execs. This, in turn, negatively affects the bottom line of the business, which isn’t good for anyone. And it isn’t getting any easier. Data is growing exponentially and the problem of integrating data from multiple sources isn’t going away any time soon. These issues, along with the complex interaction of the different components of a BI solution, continue to make the design, deployment and management of data warehouses a challenge. Now you can continue to throw money at it by over-provisioning and burning up valuable data center space and power to try to keep up, or you can strive to achieve a higher level of DW nirvana with Cisco and NetApp.
