Abstract: A method of leveraging security-as-a-service for cloud-based file sharing includes receiving, at a cloud-based file sharing server external to an enterprise network and having connectivity to the enterprise network, instructions from an enterprise network to validate a file uploaded by a first user associated with the enterprise network before allowing the file to be downloaded. The file sharing server may then receive the file from the first user and forward the file to a cloud-based security-as-a-service (SECaaS) server that is also external to the enterprise network and has connectivity to the enterprise network. The file sharing server receives a determination of validation from the cloud-based SECaaS server and allows a second user to download the file based on the determination. To make the determination, the SECaaS server retrieves cryptographic keying material from a cloud-based key management server, and decrypts the file.

Abstract: In one embodiment, a distributed denial of service attack on a network is identified. In response to the distributed denial of service attack, a script to request a short term certificate is executed. The short term certificate is generated by a certificate server and received either directly or indirectly from the certificate server. An instruction to redirect traffic using the short term certificate and private key is sent to a distributed denial of service attack protection service that is operable to filter or otherwise mitigate malicious traffic involved in the distributed denial of service attack.

Abstract: In one embodiment, first content is served by an application server to a client computer through an Internet service provider network. The first content includes a link to second content on a third-party server. A token request is sent from the third-party server to the application server in response to selection of the link by the client computer. A token is provided to the third-party server by the application server in response to the token request. The token is configured to authorize data flow at a bandwidth for the second content by the Internet service provider network to the client computer. The data flow is authorized based on an agreement for the bandwidth between an operator of the application server and an operator of the Internet service provider network.

Abstract: Various embodiments are disclosed for prioritizing network flows and providing differentiated quality of service in a telecommunications network. In some embodiments, a SecaaS can be utilized to signal flow characteristics of one or more network flows to a connector in a network so that the network can install differentiated quality of service against the one or more network flows based upon the received flow characteristics. Some embodiments enable a connector in a network to act as a PCP client to signal received flow characteristics to an upstream PCP server hosted by an adjacent access network.

Abstract: In one implementation, traffic in a mobile network is directed across multiple paths to a single cloud server or security server (e.g., a security as a service). The mobile device detects a cloud connector through a primary connection based on an attachment or connection via a first interface of a mobile device. The mobile device sends a request to the cloud connector for an identification of a cloud security server associated with the cloud connector. After receiving the identification of the cloud security server, the mobile device directs one or more subsequent data flows or subflows for a second interface or another interface of the mobile device to the cloud server or security server. The second data flow and the second interface are associated with another network that is external to the enterprise network and trusted network connection or not associated with the enterprise network and the trusted network connection.

Abstract: In one implementation, downloading of streaming content using a security as a service (SecaaS) system is more efficient because portions of the streaming content may not be inspected by the SecaaS. A first request to download content from a content provider is received, and a connection is initiated with a security provider, which inspects the first chunk of the content and generates a routing instruction based on the inspection of the first chunk of content. Based on the routing instructions and the inspection of the first chunk, a request for a second chunk of the streaming content is addressed to the content provider. The second chunk of the streaming content, circumvents the SecaaS system.
Abstract translation: 在一个实现中，使用安全即服务（SecaaS）系统下载流内容更为有效，因为部分流媒体内容可能不被SecaaS检查。 接收到从内容提供商下载内容的第一请求，并且与安全提供者发起连接，安全提供者检查内容的第一块，并且基于第一内容块的检查来生成路由指令。 基于路由指令和对第一块的检查，流式传输内容的第二块的请求被寻址到内容提供商。 流媒体内容的第二大部分规避了SecaaS系统。

Abstract: A PCP-aware firewall or other firewall validating a media session using third-party authorization receives more information than just the results of cryptographic token validation. The intent for each media stream of a media session is received from the Authorization Server. The intent may be used to compare to the received traffic of the media session. If the traffic is different than the intended traffic, then the exception to permit the firewall may be closed.
