What SDN is and where it’s going?

Forrester analyst Andre Kindness says a lot of clients ask him how they should think about software-defined networking (SDN), which has been heralded for years as the next great thing in the industry.SDN – which is an architecture approach, not a specific product - has traditionally been thought of as virtualizing data center networks. This typically means separating the management of the control plane of network devices from the underlying data plane that forwards network traffic. Using a software-defined system to control this disaggregation brings many benefits, including increased network management flexibility and being able to more easily implement fine-grained security policies.To read this article in full or to leave a comment, please click here

3 ways to track people using location-based services

There are lots of motivations driving organizations to install location-tracking technologies. The obvious driver is to find things, especially things on wheels, such as medical equipment in a hospital. It can also be smart to keep tabs on things in transit, such as a container. But the biggest reason to track things is simply because we can. We can also use these technologies to track people. Some solutions such as facial recognition can literally track people, but usually we just track a device someone might be carrying. We can now literally track the customer’s journey (through a retail store). There’s a popular misconception that global positioning satellites (GPS) are usable inside, but they range from worthless to unhelpful. GPS satellite signals require a direct line of sight to multiple satellites. To read this article in full or to leave a comment, please click here

Worth Reading: Ethernet Getting back on Moore’s Law

It would be ideal if we lived in a universe where it was possible to increase the capacity of compute, storage, and networking at the same pace so as to keep all three elements expanding in balance. The irony is that over the past two decades, when the industry needed for networking to advance the most, Ethernet got a little stuck in the mud. —The Next Platform

Oracle beefs up cloud sales team with 1,000 EMEA openings

Oracle is the latest legacy software vendor looking to reorganise its sales teams to be more focused on cloud services, as it announces 1,000 job openings in EMEA.Oracle is targeting "people from diverse backgrounds and profiles with between two to six years work experience", the official press release states.This follows some positive financial results for Oracle, as it posted a 66 percent year-on-year growth in cloud revenues for Q4 2016. That figure comes in at $1.4 billion and includes PaaS, IaaS and SaaS, which has been boosted by the recent NetSuite acquisition. By comparison AWS posted revenues of $3.66 billion in its latest results back in April.To read this article in full or to leave a comment, please click here

2 reasons to migrate off of Microsoft Exchange Server

A few weeks back, I wrote that “choosing Microsoft Windows for your organization should get you fired.”It’s a statement that, while certainly a bit on the inflammatory side, I completely stand by—mostly due to the known insecure nature of running Windows as a server operating system.What I didn’t do was give specific examples of what to move your existing Windows-based infrastructure to. Sure, the obvious answer for most SysAdmins is simply “migrate the servers over to Linux.” But what about specific server applications that your organization might already rely upon? That’s a whole other can of worms.To read this article in full or to leave a comment, please click here

Tools for TE with EIGRP

In response to my article about what would cause a directly connected route to be overridden, Matt Love (@showflogi) made a good observation:

What Matt is saying is that longest prefix match (LPM) is a mechanism that can be used to steer traffic around the network in order to meet a technical or business need. This type of traffic steering is called traffic engineering (TE).

LPM refers to how route lookups work on a Layer 3 device: the longest, most-specific match is always chosen. Like I explained in the prior post, if the routing table contains 10.10.10.0/24 and 10.10.10.64/26, the latter route will be used to forward traffic to 10.10.10.100 (as an example) because a /26 is longer (ie, has a longer prefix length) and is therefore more specific. We can use this behavior to direct traffic towards 10.10.10.100 over a specific interface or via a specific path (ie, a path with Continue reading

Nominate a Women Or Girl for an EqualsInTech Award!

Know an amazing woman or girl in tech who’s working for access, skills, or leadership? Why not shine the light on them and nominate them for an EqualsInTech Award!

Equals is an initiative delivered by a committed partnership of ITU, UN Women, GSMA, ITC, and UN University joined by the Internet Society and over 20 corporate leaders, governments, non-profit organizations, communities, and individuals around the world working together to bridge the digital gender divide – by bringing women to tech, and tech to women.

Using Geolocation in Firepower Access Control Policies

The use of geolocation is fairly obvious in monitoring networks with Firepower Management Center. What may be less obvious is that Continents and Countries can also be specified as the source or destination of connections in an Access Control Policy. Basically, this geographical information becomes one more match criteria that can be used to identify traffic for a block or allow action.

To get to this capability, open the Access Control Policy that is in use by the Firepower device. Within the policy, open or create an applicable rule. On the network tab (where you configure the source and destination addresses) a Geolocation tab can also be found. Clicking on this tab exposes Continents and Countries. These can be added as sources and/or destinations.

ACPGEO

Note to reader: All Firepower content can be accessed by clicking here (or choosing Firepower from the menu at the top of the page).

As can be seen in the diagram above, I am creating a rule to block traffic to France. Before I save and deploy the policy changes to the device, I will confirm reachability to an IP address that exists in that part of Europe.
