Notes on the FCC and Privacy in the US
I’ve been reading a lot about the repeal of the rules putting the FCC in charge of privacy for access providers in the US recently—a lot of it rising to the level of hysteria and “the end is near” level. As you have probably been reading these stories, as well, I thought it worthwhile to take a moment and point out two pieces that seem to be the most balanced and thought through out there.
Essentially—yes, privacy is still a concern, and no, the sky is not falling. The first is by Nick Feamster, who I’ve worked with in the past, and has always seemed to have a reasonable take on things. The second is by Shelly Palmer, who I don’t always agree with, but in this case I think his analysis is correct.
Last week, the House and Senate both passed a joint resolution that prevent’s the new privacy rules from the Federal Communications Commission (FCC) from taking effect; the rules were released by the FCC last November, and would have bound Internet Service Providers (ISPs) in the United States to a set of practices concerning the collection and sharing of data about consumers. The rules were widely heralded Continue reading

Multistage MC-LAG in Data Center
1 Executive Summary
Compute virtualization and converged infrastructure has introduced tremendous changes in Data Center networks. Traditional network design (Core, Aggregation and Access layers) coupled with Spanning tree protocol for management of layer 2 loops could not simply afford requirements of virtual machine mobility and elephant flows required for modern applications. All major network vendors have collaborated and brought new technologies to solve modern day Data Center challenges. 3 tier traditional networks are being replaced with flat switching fabric or scalable IP-Fabric.
2 Multi-Chassis LAG, A Solution
Multi-Chassis Link Aggregation Group is another solution besides “Switching Fabric and IP Fabric” where access devices or servers can have active-active connectivity and traffic load sharing on links connected with 2 different network devices. The basic idea is to prune effects of spanning tree protocol and offer active-active topology and redundancy for link and device safe fail-over.
In this solution paper; we will discuss how to design a Data Center network for small to medium organization with collapsed core architecture (Core and aggregation layers combined in single layer) with active-active multi-homing between server and access layer switches and active-active multi-homing between access and core layer network devices. Thus completely removing spanning Continue reading

10000 percent more expensive SFPs
Cisco genuine SFP for 1000BASE-BX BiDi is 100 times more expensive than a compatible product. Choosing two random sites, Walmart sells Cisco genuine part for $829, Fibrestore sells same component for $7.29.
Proving that Enterprise IT really doesn’t care about price, ROI, or value for money. Thats just management self-justifying their lack of talent and ability to measure risk.
Private Cloud will never compete with public cloud while price distortions like this are commonplace.

Research: McAfee Labs Threats Report April 2017
Network professionals are the front line in cyber-defence by defining and operating the perimeter. While it is only a first layer of static defense, its well worth understanding the wider threat landscape that you are defending against. Many companies publish regular reports and this one is from McAfee.
McAfee Labs Threats Report – April 2017 – Direct Link
Landing page is https://secure.mcafee.com/us/security-awareness/articles/mcafee-labs-threats-report-mar-2017.aspx
Note: Intel has spun McAfee out to a private VC firm in the last few weeks so its possible that we will see a resurgence of the McAfee brand. I’m doubtful that McAfee can emerge but lets wait and see.
Some points I observed when reading this report:
- McAfee wants to tell you about its cloud-based threat intelligence (which all security vendors have now, table stakes)
- The pitch is pretty much identical to any other cloud threat intelligence.
- The big six security companies have formed the Cyber Threat Alliance ( ….to prevent the startups from competing with them ? ) aka. Check Point, Cisco, Fortinet, Intel Security, Palo Alto Networks, Symantec
- Big section on Mirai botnet and how it works.
- Good summary of the different network packet attack modes in Mirai. Nicely laid out with Continue reading
