I’m a couple of days late with this post for Data Privacy Day,, but not too late for Data Privacy Month (February). I wanted to highlight it anyway (and maybe I’ll put it on my calendar so I don’t forget next year). The point, of course (“you don’t need to have a point to have a point”) is that each and every one of us—that’s you and I, in case you’ve not gotten it yet—need to take security seriously. Security begins with you. To this end, the Cloud Security Alliance has a good post up on what you can do to improve data privacy.
Avoid problems by taking these factors into account when designing Layer 2 DCIs.

The Corebot banking trojan was initially discovered and documented last year by researchers at Security Intelligence. Since then, it has evolved rapidly and, in terms of capabilities such as browser-based web injections, it is now similar to the dominant banking malware such as Zeus, Neverquest, and Dyreza although its actual impact to date is nowhere close.
ASERT has been studying and monitoring Corebot since shortly after it was initially documented and an in-depth analysis of Corebot’s inner workings are provided in this threat intelligence report, including coverage of its cryptography, network behavior, and banking targets.

ASERT has been analyzing samples of a banking trojan targeting South Korean financial institutions. We call the banker “Big Bong” and provide, in this threat intelligence report, an in-depth behavioral analysis of the malware from builder to bot and from installation to exfiltration including obfuscation techniques, certificate use, and VPN-based network communications. A goal hypothesis is put forth – “The Big Bong Theory,” including some background on the South Korean banking infrastructure. This intelligence report will be of interest to security researchers, incident responders, and anyone interested in advanced malware analysis.
Sometimes IT support means a whole lot more than troubleshooting hardware and software.
One of the comments added to my Using BGP in Data Centers blog post said:
With symmetric fabric… does it make sense for a node to know every bit of fabric info or is reachability information sufficient?
Let’s ignore for the moment that large non-redundant layer-3 fabrics where BGP-in-Data-Center movement started don’t need more than endpoint reachability information, and focus on a bigger issue: is knowledge of network topology (as provided by OSPF and not by BGP) beneficial?

This is also where we create a delineation between ‘trusted’ and ‘untrusted’ networks. Regardless of how you define this boundary, it becomes the focal point for any security related tooling. This creates some interesting challenges…
Scale – Applying security tooling at the external edge introduces some possible scale concerns. You now have a single point in the network has to scale to provide connectivity and security services to all of the users and applications. While this might make sense in smaller networks, aggregating everything in one place on larger networks can be challenging. Considering that many security tools can handle significantly lower amounts of traffic than routers and switches, you may find that doing this all in one place introduces a bottleneck in the network. Scaling security appliances is often a much larger task than scaling network links.
Network magic – I often joke that network engineers have to perform network magic to get all of the security tools all of the traffic they Continue reading
