This article introduces you how to achieve SaaS cloud computing encryption, the content is very detailed, interested friends can refer to, I hope it can be helpful to you.

SaaS cloud computing is a software application that is shared with others, and even the most famous vendors often need to access our data in some locations. They will never peek, there may be a lot of security and audit controls for access, but eventually our data is somewhere in the database, and there are others in the same location who will manage and keep running.

SaaS cloud computing security involves many different controls, including identity management, internal security settings and role management, event response and service deactivation planning, and auditing. In this article, we will focus on technologies that protect sensitive data stored in SaaS cloud computing applications, including SaaS cloud computing encryption.

There are four main options, but unless you use a file-oriented service, only two of them make sense to you:

1. Trust vendors and rely on their internal controls (which may include encryption, data dispersion, and other options).

two。 If the service provides a client application with this capability, there is usually only one option before sending encrypted data from the customer application to the vendor.

3. Encrypt data locally before sending it to the service.

4. Using a local or remote encryption agent, encrypt and decrypt the data that will be provided to the vendor.

Trusting vendors is not always a bad thing; many vendors adopt better security controls than you do in your internal applications. We still refer to some use cases, such as you may need to protect some of the information you have, and this is where other options work.

SaaS Cloud Computing encryption method

Some services provide a client application that does not necessarily need to run anything through a web browser. This is common in file storage and backup applications that combine SaaS cloud computing and PaaS capabilities. Some of these services allow you to encrypt your data in the client application before sending it to their server, while security services even allow you to manage your own keys. This leaves them completely unaware of your data, although they can usually see metadata. Over time, I'd like to see some features that extend encrypted data within web browsers, but I haven't seen any implementation applications yet.

Client-side encryption is great, but it's not always an option (especially for non-file-oriented services). Another option is to use your own software to encrypt locally before sending it to the Internet. This can be difficult to manage, and I almost only see this option applied to file-based data. There are also some solutions aimed at masks, that is, locally intercepting encrypted data blocks of network forms, but this option is not commonly used and is not an avant-garde technology with an uncertain market future.

The final option is to use some kind of web-based encryption agent, which is the solution that most enterprises seek when they do not fully trust their suppliers.

The agent is placed on the network and operates as a network gateway. When users visit the SaaS cloud computing website, they are redirected through an agent. The agent relies on deep knowledge of SaaS cloud computing applications and blocking key constituent domains of web pages. Before sending it to the vendor, encrypt sensitive data located in these domains and decrypt it before sending it back to the user.

For users, it looks like accessing a service, as long as they use proxies on the network. But if they try to access the customer's account number by connecting directly to the SaaS cloud computing application, all they see is encrypted data. For not providing fine-grained access control services as you need, you can mask data from users and get security that exceeds the internal control of the application. In addition, you can technically host the agent itself in cloud computing to support remote access.

This should be obvious to all, this option does not apply to any application other than major cloud computing services, and through efforts it can build interception capabilities and seamlessly integrate target services. In addition, changes in the user interface of a SaaS cloud computing application can break functionality until the agent vendor can complete the update.

SaaS Cloud Computing Security recommendations

Given these SaaS cloud computing encryption challenges, I am more inclined to make the following recommendations:

1. The best thing you can do is to work with SaaS cloud computing providers you trust and protect yourself through good contracts and audits.

two。 If you focus on file-based data, there are plenty of valid encryption options; most file-based enterprise encryption tools work well.

3. If you don't trust your supplier at all, look for a proxy encryption solution. Encrypt as little as possible to reduce the risk of file corruption. Understand that unless you put the agent itself in the cloud, you may lose some liquidity.

About SaaS cloud computing how to achieve encryption to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
