Cisco fixes critical flaws in digital encoder, unified computing manager and security appliance

Cisco Systems has released software updates to fix critical issues that could allow attackers to compromise digital encoders, unified computing system management servers and Firepower 9000 series security appliances.The Cisco Modular Encoding Platform D9036, a hardware appliance that provides multi-resolution, multi-format encoding for applications that require high video quality, has a hard-coded static password for the root account.This is the highest privileged account on the operating system and is created at installation time. The account and password cannot be changed or deleted without impacting the functionality of the system, Cisco said in an advisory.To read this article in full or to leave a comment, please click here

Happy New Year and welcome to the VM you can punish your routers with

Hello from stubarea51.net and Happy New Year! We are back from the holidays and recharged with lots of new stuff in the world of network engineering. If you ever thought it would be cool to put a full BGP table into a lab router, GNS3 or other virtualized router, you’re not alone.

A while back, I tackled this post and got everything up and running:

http://evilrouters.net/2009/08/21/getting-bgp-routes-into-dynamips-with-video/

First of all, thanks to evilrouters.net for figuring out the hard parts so we could build this into a VM. After basking for a while in the high geek factor of this project, it gave me an idea to build a VM that could be distributed among network engineers and IT professionals. The idea is to easily spin up one or more full BGP tables to test a particular network design or convergence speed, playing with BGP attributes, etc. After a few months of tweaking it and getting the VM ready for distribution, we finally are ready to put it out for everyone to use.

TSA: Gun discoveries in baggage up 20% in 2015 over 2014

I am sure it’s not a statistic that makes anyone feel ecstatic about flying: There was a 20% increase in firearm discoveries at TSA airport checkins from 2014’s total of 2,212. +More on Network World: 26 of the craziest and scariest things the TSA has found on travelers+ It’s an astounding number really, but the details get worse. The TSA goes onto say 2,653 firearms were discovered in carry-on bags at checkpoints across the country, averaging more than seven firearms per day. Of those, 2,198 (83%) were loaded. Firearms were intercepted at a total of 236 airports; 12 more airports than last year.To read this article in full or to leave a comment, please click here

How much at risk is the U.S.’s critical infrastructure?

There is universal agreement that modern warfare or crime fighting is not just about bullets, bombs and missiles in physical space. It’s also about hacking in cyber space.But over the past decade there has been much less agreement over how much of a threat hackers are.On one side are those – some of them top government officials – who have warned that a cyber attack on the nation’s critical infrastructure could be catastrophic, amounting to a “cyber Pearl Harbor.”Those warnings prompted the recent book by retired ABC TV “Nightline” anchor Ted Koppel titled, “Lights Out: A Cyberattack, A Nation Unprepared, Surviving the Aftermath.”To read this article in full or to leave a comment, please click here

Data breach numbers still high in 2015

New year, new leakImage by Eli ChristmanThe number of U.S. data breaches tracked in 2014 hit a record high of 783 in 2014, according to a recent report released by the Identity Theft Resource Center. 2015 fell just two breaches short of tying that record. Here is a list of those breaches that compromised more than 1 million records (see the full report).To read this article in full or to leave a comment, please click here

Cybersecurity much more than a compliance exercise

Even as an overwhelming majority of large global enterprises feel vulnerable to data breaches and other security threats, too many organizations continue to approach cybersecurity as a compliance exercise, according to a new survey from the security vendor Vormetric.In a poll of more than 1,100 security executives around the world, 91 percent of respondents consider their organization to be vulnerable to internal or external data threats.And yet, 64 percent of respondents express the view that compliance is a "very" or "extremely" effective strategy in staving off data breaches, up six percentage points from last year's survey.To read this article in full or to leave a comment, please click here

Worth Reading: ARM

ARM announced the Cortex-A72, the high-end successor to the Cortex-A57, near the beginning of 2015. For more than a year now, SoC vendors have been working on integrating the new CPU core into their products. Now that mobile devices using the A72 are imminent, it’s a good time to discuss what makes ARM’s flagship CPU tick. -via tom’s hardware

26 of the craziest and scariest things the TSA has found on travelers

More guns and ammo foundGuns and ammo continue to be the scourge of the TSA. Week after week of the agency’s own blog report on what its agents find on people looking to travel through the country’s airports are inundated with stories of loaded guns and ammunition. We won’t go into the ridiculous gun situation but will look at the weirder stuff the TSA has found folks traveling with, like meat slicers and Chihuahuas. Take a look (all entries are from the TSA Blog site).To read this article in full or to leave a comment, please click here

OpenSwitch in an OVA

First, disclaimer: I’m an HPE employee. Hewlett Packard Enterprise is a major contributor to the OpenSwitch project. Just thought you should know in case you think that affects my opinion here.

If you need more info on the OpenSwitch project, you can check out the other post in this series here and here

Network Engineers Don’t Like Learning New Things

Got your attention, didn’t I? After the first couple of posts on OpenSwitch and a lot of discussions about this cool new project at some recent events, there was one piece of feedback that came back fairly consistently from the traditional engineers. OpenSwitch is hard to get running because there’s so many new things to learn.

When released in November of last year, the initial demonstration environment was actually pretty simple and streamlined to get up and running, as long as you’re a developer.

The process involved the standard set of dev tools:

Virtual Box
Vagrant
DockerToolbox
Docker

For anyone involved in a development environment, these tools are like an old hoody on a cold winter day. Welcome and familiar.

But for the majority of network engineers who are far more comfortable with a console cable and Continue reading
