How to Keep Your Data Secure in the Cloud

»Posted in Cloud, Guides

The number of users who store their files in the cloud increases every year. Truth be told, we tend to trust cloud hosting services more than we did five years ago. These days we are even storing confidential documents, credit cards and other sensitive data in the cloud.

But what is the cloud in the first place? Basically, it’s a network of computers that are interconnected, making their CPU power and (most of all) storage space available to the users. But is the cloud really a safe, secure hosting service? The providers claim that it is, and to a certain degree they are right. Nevertheless, there are several things that you can (and should!) do on your end, to keep your files safe.

  1. Don’t keep sensitive data in the cloud

It may be tempting to store all your data on the web, but the reality is that some information should never leave your computer. Keep your movies and photos on the web if you want, but don’t entrust all your sensitive data into the hands of a service provider who may lose it or, even worse, abuse it! That’s why encrypted pen drives and portable hard drives were invented, after all.

  1. Back up your data locally as well

Always have an extra backup of your data. If you only keep a copy of your files in a cloud account, you risk losing them in case that the provider has to go through an unplanned, unwanted event – a flood, for example.

  1. Utilize cloud services that are able to encrypt your data

According to George Hardesty from Data Alliance, most providers encrypt the connection between your computer and theirs, but only a few of them will encrypt your data when it arrives in their data centers. Always choose cloud services that are able to provide local encryption. If your encrypted data falls into the hands of somebody else, they will have to work really hard if they want to decrypt it.

  1. Encrypt your data before storing it into the cloud

This step will offer an additional, high level of security. Did you know that applications like WinZip can also encrypt your data archives? By encrypting your data locally, before sending it to the cloud, you are significantly increasing your chances of keeping the private info confidential, even if it falls into somebody else’s hands.

  1. Use strong passwords

Cloud service providers will often times tell you to use strong passwords. Don’t ignore their advice; it’s much better to type in a longer, but much safer password when you access your data, rather than have a password that can be easily broken.

  1. Monitor your online behavior

Even the best cloud service security won’t be of help if somebody has installed a keylogger application, or another piece of malicious software on your computer. Be wise while you’re browsing the web, and avoid visiting shady websites. Resist the temptation to install that plug-in, even if that’s the only way for you to see that movie. 99% of the time, those so called plug-ins are in fact viruses that will infect your computer, steal your passwords and data and forward them to their creators.

  1. Use a good antivirus

These days, if you’re browsing the web without having an antivirus installed on your computer, you are exposing yourself to a great risk. Fortunately, websites like AV Comparatives regularly test the top antiviruses and publish their results online. Make sure to choose an antivirus that has a great threat detection rate and don’t forget to update it on a regular basis.

Cloud services may be safe, but their security features won’t be of too much help if your computer is the weak link. The good news is that by applying these tips, you will significantly lower the risks of getting your precious data stolen.
