IDG Contributor Network: 5 cybersecurity trends to watch for 2016

We may welcome in the New Year with open arms, but we must also prepare for the cybersecurity threats ahead of us. The 2015 Cost of Data Breach Study from IBM and the Ponemon Institute put the average cost of a data breach at $3.79 million, and that figure is expected to grow in the year ahead. With the right resolutions, you can drastically reduce your chances of falling prey to cybercriminals.Here are five major trends in cybersecurity that you should have in mind when updating your InfoSec plans for 2016.To read this article in full or to leave a comment, please click here

Third try is no charm for failed Linux ransomware creators

Getting cryptographic implementations right is difficult. A group of malware creators is currently experiencing that hard truth, to the amusement of security researchers.For the past several months, a group of cybercriminals have been infecting Linux systems -- primarily Web servers -- with a file-encrypting ransomware program that the security industry has dubbed Linux.Encoder.This development is worrying, because Web server infections don't require user interaction as on desktop computers where getting users to open rogue email attachments or visit malicious websites are common attack vectors. Instead, the hackers use automated scanners to find servers that host vulnerable applications or have weak SSH passwords they can guess using brute-force methods.To read this article in full or to leave a comment, please click here

Passed the CCDE written. Now what?

I was fortunate enough to finally pass the CCDE written exam yesterday morning.

That begs the question of “Now What?”

Well, I will spend a couple of days putting together a study strategy, based on where I am now compared to where I need to be in order to pass the exam. As it looks now, I am probably going for a fall 2016 exam date. That gives me enough time to settle into a new job with everything that entails.

It also means that I will need to spend 2-3 hours of study per day (some weekends more than that), with a combination of watching Cisco Live 365 videos and reading CVD’s/Books.

On top of that, my good friend Daniel Dib and I, along with hopefully a few others will have some design discussions using Webex. We have been told its really important to iron out different design ideas with other people. Especially if we can get a group together with people from different areas of expertise (Datacenter, Service Provider, Enterprise etc.).

Alas, an update to this story will come shortly! :)

Take care!

Creating VLAN interfaces in Linux

Communicating over multiple VLAN's is possible by using VLAN sub interfaces in linux. A vlan interface can be created in linux which shows up as a network interface device. Each of these interfaces are used as you would use a normal linux interface - assign an IP to it, attach it to a bridge, add routing tables entries and more. One use case is when you need a VM to act as an L2 gateway having one leg on one VLAN and another leg on the other.

As always this can be achieved in multiple ways: using the vconfig command, adding a new interface network-script file (CentOS/Redhat) or by using the "ip" command. I will describe all three methods here:

First thing you will need is to load the 8021q linux kernel module that is responsible for VLAN tagging/untagging.  See RFC.

Check if you have VLAN module. You can check the ouput of lsmod and figure out if 8021q is loaded or I simply like to do this:

 lsmod | grep 8021q

You should see 8021q and some other lines in the output.

Add module to linux. Note that you'll need to automate this. You can add it in systemctl Continue reading
