Hyper-converged infrastructure – Part 1 : Is it a real thing ?

Recently I was lucky enough to play with Cisco Hyperflex in a lab and since it was funny to play with, I decided to write a basic blog post about the hyper-converged infrastructure concept (experts, you can move forward and read something else ? ). It has really piqued my interest. I know I may be […]

IBM touts full data encryption in new Z series mainframes

IBM has introduced the 14th generation of its Z series mainframes, which still sell respectably despite repeated predictions of their demise. One of the major features being touted is the simple ability to encrypt all of the data on the mainframe in one shot. The mainframe, called IBM Z or z14, introduces a new encryption engine that for the first time will allow users to encrypt all of their data with one click—in databases, applications or cloud services—with virtually no impact on performance.The new encryption engine is capable of running more than 12 billion encrypted transactions every day. The mainframe comes with four times more silicon for processing cryptographic algorithms over the previous generation mainframe along with encryption-oriented upgrades to the operating system, middleware and databases.  To read this article in full or to leave a comment, please click here

NASA’s CTO tells enterprises how to network IoT

The internet of things combined with cloud computing is the platform for innovation that is used by NASA’s Jet Propulsion Laboratory and that should be used by enterprises, but it means setting up the right network infrastructure, JPL’s CTO says.“Number one, build an IoT network that’s separate from the regular network,” says Tom Soderstrom, the JPL CTO. “That’s what we did, and we found that it was amazing.”To read this article in full or to leave a comment, please click here

IBM wants you to encrypt everything with its new mainframe

IBM wants businesses to use its new z14 mainframe to encrypt pretty much everything -- an approach to security it calls pervasive encryption.Encrypting everything, and restricting access to the keys, is one way to reduce the risk and impact of data breaches. It can reduce the threat surface by 92 percent, according to research commissioned by IBM.To make such pervasive encryption viable, the z14 has four times as much silicon devoted to cryptographic accelerators as its predecessor, the z13, giving it seven times the cryptographic performance.To read this article in full or to leave a comment, please click here

Juniper VXLAN Configs: Configuring VXLANs on Juniper MX Series Routers

Today I am going to have the scenario where i am going to explain and provide you the VXLAN configurations on Juniper MX series router with the topology. VXLAN as you already knew that these are Virtual extensible LAN used to extend the layer 2 and layer 3 traffic across the public or private network or generally in the case of two datacenter connectivity.

I wrote some of the articles where i put some of the configurations and the basic information about the VXLAN. Below are the links if you want to review the same

Above are some of the topics on the VXLAN and I will come up with more VXLAN topics in the near future. Below is the topology of the VXLAN where VXLAN is configured to run on a default bridge domain. In this topology, the VTEP interfaces sources are configured to the loopback address, and VLAN groups are configured under bridge domains with VXLAN enabled. Here the interfaces are configured for VLAN tagging and Continue reading

What is FlexConfig in Firepower Threat Defense?

Earlier this year, Cisco released Firepower 6.2.0. With that release came a feature called FlexConfig. Someone is digging around the UI might not initially understand the purpose or function of this configuration option. A really quick answer to this is that the user interface is incomplete when compared to the underlying feature capability found in Firepower Threat Defense.

A good way to better understand FlexConfig is to work through an example. Those with an ASA background will understand the modular policy framework (MFP). This feature exists in Firepower Threat Defense but its non-default configuration options are absent from the user interface. So if there is a need for a specific configuration, FlexConfig is the tool to complete this task. One use case might be the need to disable SIP inspection. In the ASA configuration, this would typically be as simple as the following.

policy-map global_policy
 class inspection_default
  no inspect sip

Since Firepower Management Console is GUI driven and is the UI for FTD, this is not an option. Ideally, there would be a complete menu system and API. Since this is not currently the case, FlexConfig is the tool that provides us an override of the defaults that aren’t exposed in the UI.

Rough Guide to IETF 99: A Sampling of Encryption-Related Activities

Encryption is once again a hot topic, and there’s much to discuss at IETF 99 this week in Prague. This time the hottest action will definitely be in the Transport Layer Security (TLS) working group. TLS is considering everything from privacy implications for TLS1.3 to how to reduce handshake latency. As mentioned in previous Rough Guide blogs on the topic, the working group is busy on the completion of the TLS 1.3 specification. It has completed working group last call, and the working group is addressing the comments received during that process. Draft 21 was released on 3 July in anticipation of this week’s discussion.
