Getting started with Kubernetes using Ansible

Some of you will recall that I had previously written a set of SaltStack states to provision a bare metal Kubernetes cluster.  The idea was that you could use it to quickly deploy (and redeploy) a Kubernetes lab so you could get more familiar with the project and do some lab work on a real cluster.  Kubernetes is a fast moving project and I think you’ll find that those states likely no longer work with all of the changes that have been introduced into Kubernetes.  As I looked to refresh the posts I found that I was now much more comfortable with Ansible than I was with SaltStack so this time around I decided to write the automation using Ansible (I did also update the SaltStack version but I’ll be focusing on Ansible going forward).

However – before I could automate the configuration I had to remind myself how to do the install manually. To do this, I leaned heavily on Kelsey Hightower’s ‘Kubernetes the hard way‘ instructions.  These are a great resource and if you haven’t installed a cluster manually before I suggest you do that before attempting to automate an install.  You’ll find that the Ansible role Continue reading

Consultant urges never pay ransomware demands

When ransomware criminals lock up files and demand payment to decrypt them, don’t pay, was the advice a consultant gave to a group at SecureWorld.When there’s no risk of losing crucial data, that’s easy to say, and to make is possible requires planning, says Michael Corby, executive consultant for CGI.“Plan to have data available in a form that won’t be affected by ransomware – encrypted and stored separately from the production network,” he says. “You need a clean copy of the data in a restorable form. Test that the backups work.”Restore and recover are the key words, and they should be done keeping in mind that the malware has to be removed before recovering.To read this article in full or to leave a comment, please click here

FedEx offering $5 and all you have to do is, gulp, reinstall or reactivate Flash

From time to time – very infrequently, to be more precise – I will ignore my better judgment and reenable Flash in Chrome so that I can watch a particularly enticing cat video or whatever.I would do this more often, however, if more companies followed the lead of FedEx and offered me $5 just for doing so. Really, look: FedEx OK, it’s $5 off a purchase of $30 or more, but still seems like a good deal … unless you forget to deactivate Flash when you’re done.To read this article in full or to leave a comment, please click here

Apple: Macs and iPhones are safe from newly revealed CIA exploits

The Mac and iPhone exploits described in new documents attributed to the U.S. Central Intelligence Agency were patched years ago, according to Apple.WikiLeaks released a new set of files Thursday that supposedly came from the CIA. They contain details about the agency’s alleged malware and attack capabilities against iPhones and Mac computers.The documents, dated 2012 and earlier, describe several “implants” that the CIA can install in the low-level extensible firmware interface (EFI) of Mac laptop and desktop computers. These EFI rootkits allow the agency's macOS spying malware to persist even after the OS is reinstalled.To read this article in full or to leave a comment, please click here

Microsoft delays tools for third-party Cortana integrations

Microsoft has delayed the release of its tools for connecting other services to the Cortana virtual assistant, a decision that could cause it to lose ground in a crowded industry.The tech titan announced the Cortana Skills Kit in December of last year, saying at the time that it would be released to the public in February. As Microsoft watcher Brad Sams noted on Twitter, Microsoft missed that deadline, and the Skills Kit remains locked in a private beta with a select group of partners. Microsoft didn’t offer an explanation for the delay, saying in a statement that the kit will be coming soon.To read this article in full or to leave a comment, please click here

Google Play faces cat and mouse game with sneaky Android malware

What’s the best way to avoid Android malware? Downloading all your apps from the Google Play store -- where software is vetted – is perhaps the best advice.  But that doesn’t mean Google Play is perfect.Security researchers do find new Android malware lurking on Google’s official app store. That’s because hackers are coming up with sneaky ways to infiltrate the platform, despite the vetting processes that protect it."Eventually, every wall can be breached," said Daniel Padon, a researcher at mobile security provider Check Point.To be sure, most Android users will probably never encounter malware on the Google Play store. Last year, the amount of malicious software that reached the platform amounted to only 0.16 percent of all apps, according to a new report from Google.To read this article in full or to leave a comment, please click here
