In-transit encryption prevents this from happening and provides another layer of security for your data. Even though attackers may not be able to decrypt your data, they can still hold it hostage. Client-side encryption doesn’t prevent attackers from intercepting the transfer and seizing your encrypted data. Encryption at this stage ensures your data is not vulnerable to interception while it’s in motion. The transfer occurs over encrypted connections established by the provider. Second stage: Encryption for data in transitOnce your data is locally encrypted on your computer, it will be transferred to the provider’s remote server. The data is therefore protected against backdoor access and outside hackers because your key is not stored with the provider. Only you can decrypt the data using your key. Encryption at this level is crucial because it makes all your files unreadable by everyone. This is called client-side or zero-knowledge encryption. Without knowledge of your key, the provider has no access to the data stored on its server. A copy is not shared with the provider, so it has “zero knowledge” of your key. So let’s look at the different stages in more detail without getting too technical.įirst stage: Client-side encryption for data before transit Before you transfer your data from your computer to the provider’s server at their data center, you encrypt your data locally on your hard drive with a private encryption key using the provider’s tool. Then you can make an informed decision as to which provider to use. My goal is to help you understand why encryption at each stage of data transfer is important. A good cloud storage provider encrypts your data at three different stages to provide the most protection: (1) before it leaves your computer, (2) in transit to the provider’s server, and (3) when it is stored on the provider’s server. Data can be encrypted at several levels, but not all vendors encrypt data at every crucial level. Encryption, which makes data unreadable, plays a big role in data protection. The risk of malpractice exposure if client data is compromised or breached is something lawyers need to evaluate.īefore you choose to store your client data with an online third-party vendor, take some time to understand how that data is secured and protected. Issues of whether data is encrypted and who has access to the data make some lawyers understandably nervous about having a third party store their client information. However, the use of these common cloud storage services presents some data security concerns. Many use Dropbox and Google Drive for this purpose. Lawyers increasingly rely on the cloud to store, share, and synchronize their client files.
