A cloud service is a service made available to users on demand via the Internet from a cloud services provider. Examples of cloud services include online data storage and document collaboration solutions, web-based email services and more, such as Microsoft 365 and Dropbox.
Cloud services are designed to provide easy, scalable access to applications, resources and services. However, as web behavior has become more complicated, IT departments are facing many security problems posed by the use of cloud services, like enforcing browser type policies, blocking large file transfers to save bandwidth, and blocking web file uploads.
Cloud service filtering can help your organization get a handle on employee use of cloud services. For example, control access to cloud services by allowing logon with only corporate account credentials.
TMWS allows administrators to create cloud service filters to set HTTP request related criteria based on request methods, URLs, and headers, and then add these filters into cloud access rules to together monitor cloud service usage and enforce security policies.
TMWS provides six default filters for common scenarios, such as blocking social networking services (SNS) uploads, or regulating web access through the use of certain types of browsers, or controlling access to a cloud service. You can open these filters and adjust them as necessary.
Cloud service filters cannot inspect the data payload of HTTP packets. For example, it cannot look for pattern matching inside the text or file of a webmail or social networking site post. It can only identify that a POST action is happening to a defined site or set of sites and update the header fields of the corresponding request message as configured.
