Cloud Storage Security and Its Importance

Companies and individuals alike have been shifting their data to cloud storage and cloud storage spaces. This practice has become essential as governments demand the creation of backups. However, even if that wasn’t the case, people would still go for backup to ensure that their favorite music, pictures, videos and documents would last as long as they do if not longer. To ensure the availability and integrity of your data, the cloud storage provider you hire should guarantee that your data doesn’t into the wrong hands. This is more important for organizations that may face legal hassles if their files and documents are compromised. If you’re concerned about the security of cloud storage and this is the only obstacle between you and this service, read on to get your facts right.

Why Cloud Storage Security is Important

A survey by One.com shows that 66% of people focus on security when selecting a web service like online storage. Therefore, service providers vie for their business by highlighting just how secure their offerings are. That aside, online storage security is important because: Data Can Be Stolen This is the era of hackers and identity thieves. Anyone can access your sensitive data and use it for their own benefit and your ruin. Even your pictures will be at risk without high level security measures. Data Can Be Manipulated When data is intercepted, i.e. observed or copied while on the move, chances are that the hacker plans to change a thing or two to incriminate you or bring you harm. For example, if a company uploads its employee invoices regularly, there’s a good chance someone may try to change that data and put the company in legal trouble. Data Can be Lost It isn’t hard to delete a file on an unsecured online storage server. With cloud storage security, you won’t have to worry about breaking any e-discovery laws or “misplacing” important files.

How Data is Protected

When dealing with cloud storage, data can be vulnerable at any time. However, to give you a better idea on this regard, here are the three stages of data and their level of vulnerability.

  1. Data in Transit As the name implies, data in transit means that the data is being moved or transferred from one location to another. Speaking specifically about cloud storage, this is the case when you are uploading your files to the remote server or sharing them with other users. In this case, the data is being transferred bit by bit, a process which can take anywhere from a few minutes to several hours. Therefore, there is a chance of someone hacking the server during the transfer of data and gaining access to it. There are two main types of encryption used to keep data safe during transit: TSL and SSL. Transport Security Layer (TSL) prevents ‘eavesdropping’ while data is being moved from one server to another. TSL is the encryption standard used by websites that demand visitors to provide personal information. The second encryption type is Secure Socket Layer (SSL). It is the predecessor to the TSL. Though SSL has been used effectively for many years, the TSL is considered superior to it now.
  2. Data at Rest Data at rest is basically the data that has been uploaded to the server and has been synchronized but is neither being used nor transferred. Data at rest can be compromised if someone gets hold of your login ID and password. The risk of hacking is also present. This is why data at rest is at a greater risk than data in transit. To protect data at rest, Advanced Encryption Standard (AES) is used. Through the encryption method, an electronic key is assigned to the data that is used for encryption and decryption.
  3. Data in Use Sometimes users access the cloud to check and use the files and documents they need to use at a given moment. The simplest way to restrict unauthorized use is by limiting folder permissions. You can restrict the actions a user can perform when using a piece of data. For instance, you may only allow your employees to read a particular file but restrict editing privileges. Cloud storage services use electronic keys to encrypt data in use as well.

Which Services Offer High Security

As important as cloud storage security is, not many service providers focus on providing this essential element. Luckily, there are a few that do take this point into consideration, such as these two:

  • Box.comThis service is always working on improving its cloud storage security factor. Currently, it is working on making its clients NSA-proof by providing users with high-end encryption that it can’t break to access the files.
  • MEGAMEGA is the successor to Megauploads. The service is secure as it encrypts users’ files during transit and once safe on the service provider’s servers.
