Facebook regularly abuses the privacy of its users. Google has stopped supporting its popular RSS feeder. Apple prohibits all iPhone apps that are political or sexual. Microsoft might be cooperating with some governments to spy on Skype calls, but we don’t know which ones. Both Twitter and LinkedIn have recently suffered security breaches that affected the data of hundreds of thousands of their users.
If you’ve started to think of yourself as a hapless peasant in a Game of Thrones power struggle, you’re more right than you may realize. These are not traditional companies, and we are not traditional customers. These are feudal lords, and we are their vassals, peasants, and serfs.
Power has shifted in IT, in favor of both cloud-service providers and closed-platform vendors. This power shift affects many things, and it profoundly affects security.
Traditionally, computer security was the user’s responsibility. Users purchased their own antivirus software and firewalls, and any breaches were blamed on their inattentiveness. It’s kind of a crazy business model. Normally we expect the products and services we buy to be safe and secure, but in IT we tolerated lousy products and supported an enormous aftermarket for security.
Now that the IT industry has matured, we expect more security “out of the box.” This has become possible largely because of two technology trends: cloud computing and vendor-controlled platforms. The first means that most of our data resides on other networks: Google Docs, Salesforce.com, Facebook, Gmail. The second means that our new internet devices are both closed and controlled by the vendors, giving us limited configuration control: iPhones, ChromeBooks, Kindles, Blackberries. Meanwhile, our relationship with IT has changed. We used to use our computers to do things. We now use our vendor-controlled computing devices to go places. All of these places are owned by someone.
The new security model is that someone else takes care of it — without telling us any of the details. I have no control over the security of my Gmail or my photos on Flickr. I can’t demand greater security for my presentations on Prezi or my task list on Trello, no matter how confidential they are. I can’t audit any of these cloud services. I can’t delete cookies on my iPad or ensure that files are securely erased. Updates on my Kindle happen automatically, without my knowledge or consent. I have so little visibility into the security of Facebook that I have no idea what operating system they’re using.
There are a lot of good reasons why we’re all flocking to these cloud services and vendor-controlled platforms. The benefits are enormous, from cost to convenience to reliability to security itself. But it is inherently a feudal relationship. We cede control of our data and computing platforms to these companies and trust that they will treat us well and protect us from harm. And if we pledge complete allegiance to them — if we let them control our email and calendar and address book and photos and everything — we get even more benefits. We become their vassals; or, on a bad day, their serfs.
There are a lot of feudal lords out there. Google and Apple are the obvious ones, but Microsoft is trying to control both user data and the end-user platform as well. Facebook is another lord, controlling much of the socializing we do on the Internet. Other feudal lords are smaller and more specialized — Amazon, Yahoo, Verizon, and so on — but the model is the same.
To be sure, feudal security has its advantages. These companies are much better at security than the average user. Automatic backup has saved a lot of data after hardware failures, user mistakes, and malware infections. Automatic updates have increased security dramatically. This is also true for small organizations; they are more secure than they would be if they tried to do it themselves. For large corporations with dedicated IT security departments, the benefits are less clear. Sure, even large companies outsource critical functions like tax preparation and cleaning services, but large companies have specific requirements for security, data retention, audit, and so on — and that’s just not possible with most of these feudal lords.
The feudal relationship is inherently based on power. In Medieval Europe, people would pledge their allegiance to a feudal lord in exchange for that lord’s protection. This arrangement changed as the lords realized that they had all the power and could do whatever they wanted. Vassals were used and abused; peasants were tied to their land and became serfs.
It’s the internet lords’ popularity and ubiquity that enable them to profit; laws and government relationships make it easier for them to hold onto power. These lords are vying with each other for profits and power. By spending time on their sites and giving them our personal information — whether through search queries, e-mails, status updates, likes, or simply our behavioral characteristics — we are providing the raw material for that struggle. In this way we are like serfs, toiling the land for our feudal lords. If you don’t believe me, try to take your data with you when you leave Facebook. And when war breaks out among the giants, we become collateral damage.
So how do we survive? Increasingly, we have little alternative but to trust someone, so we need to decide who we trust — and who we don’t — and then act accordingly. This isn’t easy; our feudal lords go out of their way not to be transparent about their actions, their security, or much of anything. Use whatever power you have — as individuals, none; as large corporations, more — to negotiate with your lords. And, finally, don’t be extreme in any way: politically, socially, culturally. Yes, you can be shut down without recourse, but it’s usually those on the edges that are affected. Not much solace, I agree, but it’s something.
On the policy side, we have an action plan. In the short term, we need to keep circumvention — the ability to modify our hardware, software, and data files — legal and preserve net neutrality. Both of these things limit how much the lords can take advantage of us, and they increase the possibility that the market will force them to be more benevolent. The last thing we want is the government — that’s us — spending resources to enforce one particular business model over another and stifling competition.
In the longer term, we all need to work to reduce the power imbalance. Medieval feudalism evolved into a more balanced relationship in which lords had responsibilities as well as rights. Today’s internet feudalism is both ad-hoc and one-sided. We have no choice but to trust the lords, but we receive very few assurances in return. The lords have a lot of rights, but few responsibilities or limits. We need to balance this relationship, and government intervention is the only way we’re going to get it. In medieval Europe, the rise of the centralized state and the rule of law provided the stability that feudalism lacked. The Magna Carta first forced responsibilities on governments and put humans on the long road toward government by the people and for the people.
We need a similar process to rein in our internet lords, and it’s not something that market forces are likely to provide. The very definition of power is changing, and the issues are far bigger than the internet and our relationships with our IT providers.
