Now we’ll get back to basics and explain the many threats encryption can help protect you from.

Protect Your Data From Thieves

Encrypting your storage protects the data on it from thieves. If someone steals your laptop Track Down and Recover Your Stolen Laptop With Prey Read More , smartphone, or tablet, encryption can prevent them from accessing the sensitive data on your hard drive. The media is full of reports from business employees who lose laptops containing sensitive customer information, including credit card numbers – if only they had used encryption, they wouldn’t have embarrassed their employers and given their customers’ information over to identity thieves.

This is a dramatic example, but it’s true even for the average person. If you store financial data, business plans, or other sensitive documents, such as scans of tax returns with your social security number and other sensitive data on them, you should ensure your computer’s hard drive – or at least the sensitive files – are stored in an encrypted form. Encryption can also help protect any other type of private data that you don’t want someone else seeing.

Store Files Securely in the Cloud

Cloud storage gives us a great way to keep our files in sync across all our devices, storing a backup copy on the cloud storage corporation’s servers so we won’t lose it. It’s also a great way to share files with other people.


However, storing sensitive data – like financial documents and other personal information – in a cloud storage account could be a mistake. Dropbox once allowed anyone to log into any account without a password for four hours, and this would have allowed anyone to access your Dropbox account and view your files. Your files could also be accessed if someone gained access to your account through other means, such as using a leaked password that you re-used on several website

Encrypting sensitive files prevents them from ever being accessed without the encryption key, even in a worst case scenario when your cloud storage provider’s security fails or someone else gains access to your account. Encrypthion also allows you to securely share sensitive data with other people – just agree on an encryption key ahead of time (you could even do this in person) and then use that key to share sensitive files over email or a cloud-storage service without others being able to access it.

There are even cloud storage services that automatically encrypt your data before uploading it Secure Your Files: 3 Encrypted Dropbox Alternatives Dropbox brought cloud-based file synchronization and storage to the masses, but it's been hindered by high-profile security problems. Fortunately, you have another option — an alternative service that secures your files with local encryption and... Read More , decrypting it locally when you access it.

For example, if you’re sitting in a café using public Wi-Fi and performing Google searches while not logged in, anyone on the Wi-Fi network could monitor your Google searches and any other website activity taking place over HTTP. Even if you used HTTPS to access websites, people could still see the HTTPS website you access.

Battle Over-Reaching Government Surveillance

The government is watching you. This may seem a bit paranoid, but it’s the reality of the world we live in. Our digital lives are being increasingly picked over by our governments How To Protect Yourself From Government Cellphone Surveillance [Android] Let's face it, these days the likelihood that you are being monitored by someone is rising all the time. I'm not saying that everyone, everywhere faces the threat of cellphone surveillance, but there are plenty... Read More , often without warrants or other typical legal protections. We’re not lawyers, but here are a few anecdotes that can give you an idea of the scope of what’s going on:

  • In the USA, your emails are considered “abandoned” after you open them or after 180 days if they remain unopened. This allows the US government to view your personal emails without a warrant. If you encrypted your emails, the government would require a warrant to compel you to disclose the encryption key. (Wherever you are in the world, your emails may be stored in the USA and be subject to such access, too.)
  • California’s Supreme Court has ruled that police can search through your smartphone without a warrant after arresting you. If you encrypted your smartphone’s storage, the police would require a warrant to compel you to tell them the encryption key. (Source)
  • According to the EFF, the US government and major telecom carriers have “engaged in a massive program of illegal dragnet surveillance of domestic communications and communications records of millions of ordinary Americans since at least 2001.” Your emails, phone calls, and other communications are available to the government without a warrant thanks to this warrantless wiretapping. (Source)
  • The version of Skype distributed in China has a backdoor allowing the Chinese government to snoop on their citizens’ conversations. Microsoft has refused to answer whether the version of Skype distributed elsewhere contains similar backdoors. (Source 1, Source 2)

This is just the USA – the situation is even worse in countries like China How To Quickly Check If Your Site Is Visible Behind The Great Firewall Of China The Great Firewall of China, officially known as the Golden Shield project, uses a variety of methods to block foreign websites that the Chinese government doesn’t like.

It’s not paranoid to realize that governments are building massive databases of our communications and personal data. Encryption can be a way to help prevent your data from being accessed without a warrant or automatically logged in a database.

    Aaaaand if you really want to browse anonymously, you should use a VPN AND Tor. As far as I know, ExpressVPN's the only provider that has its own .onion network. Tried it. Works great.

    I would point out that using unusually heavy encryption or TOR is likely to get yo flagged over seas. It's like the old days, with couriers walking around with laptops chained to their wrist obviously they've got something to hide. Long term, the best way to escape surveillance is to saturate it.

    People think the system look for threats, they don't, they look at everything then toss out as much info as they can until they get the suspect list down to manageable small size suspects. Such systems are like the brain, trying to ignore the infinite regress of information and just focus on the important. If everyone visiting China, ay use TOR or various encryption techniques, the system simply can't keep up.

    But we shoud remember that the NSA and the politicians of both parties in the US who have ratified its actions are doing so because we do face internet coordinated attacks on our home soil. Attacks which if not stop could alter us politically.

    Beside the invasions caused by the War on Drugs are a thousand times worse and we should burn our political capital on the big threats and let this piss-ant spying be last on the list.

    Encryption, though very useful, slows things down. Speed is something which the average user wouldn't trade for overwhelming security. Except my passwords, I do not have most of my data encrypted. This worries me a little bit but I haven't faced any problems yet. So, Status Quo.

    Yes, TrueCrypt is a great data encryption software. I have been using it for several years and recommended it to many people.

    I would like to thank TrueCrypt Foundation for the development of such a fantastic data security software which is FOC.

    I backup all my data to an external drive and also up in the cloud. Most of my files -- photos, video, music -- don't need to be encrypted. And I keep all important data in the same handful of Excel or Word files -- password protected (encrypted).

    I always have this paranoia (probably unfounded) of losing my computer and local data -- then downloading all the backup off the cloud -- only to be unable to decrypt them! But with the few password-protected Office files -- I know I can always open them.

    Zombie geek apocalypse. You never know when Geekdom will get infected as some comicon and try to steal data and end the world.

    On a serious note, if someone really wants to get into your computer, they will. If your stuff is encrypted, it won't do them any good.

    Great article. This topic should not be a feared topic but yet a topic of knowledge and know how. It makes since that there is a greater need for encryption when we consider how technology is becoming the standard for your average person. This is one aspect that I love about using Linux based systems...part of the install of the OS gives you the option to encrypt your HD or home folder (where you keep your personal data). In the past Windows OS's ( I can't speak for Windows 8) has not given factory/default option to do such a thing.
    I recently started using an Android based of the first things I had taken advantage of is using it's built in option for encryption of both the OS and my micro SD card.

    Simple answer, don't put anything online including the cloud that you're not willing to risk someone seeing. No mobile online banking, only from home on a pc you trust using an outrageously difficult password.

    Better yet, go completely off-grid and use cash only. It's easier than you think. (says the guy posting it while on the grid)

    The primary barrier to encryption is ease-of-use. Eyes usually glaze over at the mention of encryption. That is why I created ThreadThat dot com. TT provides simple, free encryption for all electronic communications. Not just SSL, but end-to-end encryption. So simple anyone can do it.
