5 biggest cybersecurity concerns in 2016

Last year began and ended with a series of high-profile cybersecurity attacks, starting with the pilfering of 80 million Social Security records at health insurer Anthem and culminating with infiltrations at Starwood, Hilton and Hyatt hotel chains. Expect digital assaults, -- ranging from standard malware to more sophisticated, clandestine entries -- to continue on leading corporate brands in 2016, according to Raytheon's Websense business. The cybersecurity software maker, which analyzed threat data from 22,000 customers in 155 countries, says hackers will conjure attacks that target emerging technologies, such as mobile payments and top-level domains.To read this article in full or to leave a comment, please click here

Think Global, Peer Local. Peer with CloudFlare at 100 Internet Exchange Points

Think Global, Peer Local. Peer with CloudFlare at 100 Internet Exchange Points

Internet Exchange Points (IXPs) or Network Access Points (NAPs) facilities are where networks meet, participating in what's known as peering, which interconnects various parts of the global Internet.

At CloudFlare we are dedicated to peering. So much so that we just joined our 100th Internet Exchange point!

What is peering?

According to Wikipedia:

“In computer networking, peering is a voluntary interconnection of administratively separate Internet networks for the purpose of exchanging traffic between the users of each network”

In reality this normally means a physical place where two different networks (they could be backbones, CDNs, mobile networks or broadband ISPs) connect their respective networks together to exchange traffic. Over the last fifteen years, there has been a major expansion in network interconnections, running parallel to the enormous expansion of the global Internet. This expansion includes new data centre facilities being developed to house network equipment. Some of those data centres have attracted massive numbers of networks, in no small part due to the thriving Internet Exchanges Points (both new and existing) that operate within them. London with the LINX and LONAP exchanges, Amsterdam with AMS-IX and NL-IX exchanges, Frankfurt with DE-CIX and ECIX exchanges Continue reading

Anyone could pull off a LostPass phishing attack to get all your LastPass passwords

Heads-up if you use LastPass as a security research released LostPass code on GitHub that bad guys could jump on immediately and an attack could be in the wild even now. In essence, if you use LastPass then you could be tricked into handing over the keys – or master password – to your digital kingdom.The LostPass attack works best in Chrome, but if you think you could spot the phishing then think again; Sean Cassidy, CTO of cloud-based cybersecurity firm Praesidio, warned that a user would not be able to tell a difference between a LastPass message displayed in the browser and the fake LostPass message since “it’s pixel-for-pixel the same notification and login screen.”To read this article in full or to leave a comment, please click here

LastPass phishing attack could have scooped up passwords

A relatively simple phishing attack could be used to compromise the widely used password manager LastPass, according to new research. Notifications displayed by LastPass version 4.0 in a browser window can be spoofed, tricking people into divulging their login credentials and even snatching a one-time passcode, according to Sean Cassidy, who gave a presentation at the Shmoocon conference on Saturday. Cassidy, who is CTO of Praesido Inc., notified LastPass of the issues. In a blog post, LastPass said it has made improvements that should make such an attack harder to pull off without a user knowing.To read this article in full or to leave a comment, please click here

Building an OpenStack home lab – The Lab

I’ve recently started to play around with OpenStack and decided the best way to do so would be in my home lab.  During my first attempt, I ran into quite a couple of hiccups that I thought were worth documenting.  In this post, I want to talk about the prep work I needed to do before I began the OpenStack install.

For the initial build, I wanted something simple so I opted for a 3 node build.  The logical topology looks like this…

The physical topology looks like this…

It’s one of my home lab boxes.  A 1u Supermicro with 8 gigs of RAM and a 4 core Intel Xeon (X3210) processor.  The hard drive is relatively tiny as well coming in at 200 gig.  To run all of the OpenStack nodes on 1 server, I needed a virtualization layer so I chose ProxMox (KVM) for this.

However, running a virtualized OpenStack environment presented some interesting challenges that I didn’t fully appreciate until I was almost done with the first build…

Nested Virtualization
You’re running a virtualization platform on a virtualized platform.  While this doesn’t seem like a huge deal in a home Continue reading
