Last year at Brucon, I talked about Cloud Security and broke new ground through using theBeer and Brewing as an analogy for cloud computing. The climax of that talk was significantafter-cloud.

But as I sat there in the speaker room as the make-up crew and hairstylists did the best theycould in the circumstances, I made myself a promise. If I got selected to talk in 2010 I wouldtake things more seriously.

No More Gimmicks

Cloud Security is not a laughing matter.

No more clowning around.

7/31/2019 skylabv2

Sorry

But my apology is two-fold. My blatant lies about gimmicks to one side...

The Cloud Security Broken Record

8

I was starting to feel like a stuck record, going on about high level cloud security issues.

I became an expert source on all things cloud security and strangely enough: cloud.

7/31/2019 skylabv2

10/56

Again, sorry...

10

I promise to mend my ways. Hence, the birth of my Skylab project. Rather than just talkingabout it, lets do something with it. Something useful, something that might just draw youinto my cloud...

7/31/2019 skylabv2

11

But I wasnt just challenging myself with Skylab. Im challenging you, my fellow infosec pros.Perhaps youre ignoring cloud, hoping it will just blow over. Or maybe, youre convincedyourself youre so busy, you just dont have time to get into it. Or perhaps, you just haventseen the writing on the wall or believe its another dot com bust in the making.

Cloud Is Coming

13

Im not here to make predictions about cloud. Personally, I see writing on the wall, but Imnot trying to convince you of that. Rather, I want to ask you a question.

7/31/2019 skylabv2

What

AreYou

DoingTo

KeepUp?

14

What are you doing to keep up? Cloud is just the latest big thing. But before that we hadvirtualization, we had VoIP, we had converged networking. I think we all need to challengeourselves a little more. Seek our own truths as it were. Stop paying attention and reacting tothe endless media sound bites by people that clearly dont get security. Do original research.

Apply the new technologies for ourselves before the people that pay our wages do...

7/31/2019 skylabv2

15

This boils down to something really simple. We have to find our Droids. Each of have droidsto seek out. What Droids are you looking for? How hard are you looking? What are youwaiting for? Dont wait til you feel youre good enough or until you have more free time. Ihope to ofer you something that may make you change your mind.

7/31/2019 skylabv2

16

For me, I wanted to commit a little more to building something. I wanted to find out whatcloud technology I could use right now to do something useful for my own R&D purposes.There are many things that can get in your way, but one big one is....

Friction is the enemy of your imagination. I dont know about you, but for me its not havingthe right set up at the right time. Im always trading one resource for another. My free diskspace is *always* on the wrong machine. I can never run enough virtual machines... Not onlythat, I have whims. I also have a Wim (looks at Wim), but they are mostly 2 diferent things...

I have kites I want to fly. I have ideas I want to quickly test. But most of them never see thelight of day, which makes me feel sad and deprives me of valuable learning lessons. Why?Because of friction. Infrastructure friction. Changing my test network setup is a pain. Illhave to shue resources around and make compromises as I dont have an army of machinesto play with. Ill have to make do and collapse multiple workloads onto single machines.Virtual machines have certainly helped - theyve given me more options than I had before.But at the same time virtual compute has highlighted that I can never own enough hardware

(I just want to run one more). Plus Ive got the virtual headache of managing an everincreasing stable of virtual machine images. I want my infrastructure to be malleable likecode and my operations to be automated. Or to put it another way, I need some seriouslubrication.

Prior Art

18

Along came project Skylab. This is my meta-idea. The idea that can help bring my otherideas to life. Skylab will help me fail faster and cheaper than I can today. This isntpessimism, this is how great ideas come to be - you just have to let all the bad ones getthemselves out of you first.

Come to the darkside my friends. Embrace the cloud. Or at least dip your toe in it so youcan backup whatever opinion you profer. If that doesnt convince you, Im ofering free sea-shell hats for cloud converts.

On Demand Test Labs

23

So Skylabs is about on demand test labs. Im sure you can think of times when you having aninflatable test lab that you can spin up and shutdown when you want could be pretty darnhandy

7/31/2019 skylabv2

24/56

Testing new/updated too

NIDS/NIPS testing

Exploit testing

Target practice

24

On the ofense side of security, there is target practice. Dont be a dummy and ride exploitsbareback. Tut tut. Always practice in a lab. For every action there is a reaction. Observe,learn, practice, profit. For your career with not be cut-short... But its not just pen-testlabs...Capture the Flag, Hands-on Practicals when hiring so-called experienced pen-testers

etc.

Its a Commodity

28

The key to remember when thinking about cloud is that its a commodity. You get what youpay for. But sometimes, commodity is just what you want.

7/31/2019 skylabv2

Infrastructure as aService

29

So what are we talking about? Were talking about using infrastructure as a service to createon-demand test labs. Were intentionally confining ourselves to just 1 layer of the cloudservices model: were ignoring Platform as a Service and Software as a Service. In fact, Skylabitself will have attributes of platform and software as a service in terms of doing some of the

heavy lifting for you.

39

Leaving cloud compute instances running at the cloud provider does actually cost money. Itis surprisingly easy to do though. Do it once and youll feel stupid, do it twice and youll findyourself writing a script to remind you not to feel stupid :)

Know the terms of service of your hosting and/or cloud provider. Check clauses aboutintroduction of malware in particular.

Overlay Networks

An overlay network is a computer networkwhich is built on top of another network.Nodes in the overlay can be thought of asbeing connected by virtual or logical links,each of which corresponds to a path,

perhaps through many physical links, in theunderlying network

43

Use cases

A VPC

Amazon VPC

44

Amazon recently opened up their Virtual Private Cloud, currently beta

This is a cloud provider specific network overlay

Hook up your existing network. Software VPN on your side, Hardware on their side.

All trac traverses the customer gateway - no Internet access from within VPC

Can use existing AMIs and Elastic Block Storage

Amazon rapidly innovating - keep up with release details!

Based on OpenVPN, uses CohesiveFT created VMs as cloud VPN endpoints

Supports multicast.

Recently created the cloud security forum (cloudsecurity.org/forum)- an independent hangout for IT and IT security people to discuss cloud security issues

Topic areas out as per CSA security domains

Theres a dedicated forum for Skylab which Ill be posting to with progress updates.

If you have suggestions for Skylab, please share with me there.

Stefan made some great images and all credit is due to him.

Im also extremely grateful for all the open source software Im gluing together for thisproject. Skylab would have been very dicult, it not impossible, for a sole person to piecetogether without all the efort from numerous developers.
