    Abstract: A Dynamic Name Server (DNS) surrogation method, a DNS system, and a DNS server provide DNS surrogation which is the idea that if a user device sends a DNS resolution request to a given DNS server that server does not need to actually perform the recursion itself. A policy can be defined telling the server that first received the request to take other factors into account and “relay” or “surrogate” that request to another node. This additional node is called a “surrogate” and it actually performs the recursion therefore allowing the resolving party to perform proper localization, optimization, or any other form of differentiated resolution. This surrogation also distributes the job of actually performing resolution, which adds scalability to the DNS server or service itself. A network of “surrogate” resolvers is possible as well as the concept of every client needing DNS resolution can also become a surrogate.

    Abstract: A cloud-based security method using Domain Name System (DNS) includes receiving a request from a user device at a DNS server; performing a security check on the request based on a policy look up associated with the user device; responsive to the policy look up, performing a DNS security check on the request; and responsive to the DNS security check, performing one of allowing the request to the Internet; blocking the request based on the policy; and providing the request to inline inspection based on the policy, wherein the request is one of allowed to the Internet or blocked based on the inline inspection.

    Abstract: The present disclosure relates to systems and methods for cloud-based 5G security network architectures intelligent steering, workload isolation, identity, and secure edge steering. Specifically, various approaches are described to integrate cloud-based security services into Multiaccess Edge Compute servers (MECs). That is, existing cloud-based security services are in line between a UE and the Internet. The present disclosure includes integrating the cloud-based security services and associated cloud-based system within service provider's MECs. In this manner, a cloud-based security service can be integrated with a service provider's 5G network or a 5G network privately operated by the customer. For example, nodes in a cloud-based system can be collocated within a service provider's network, to provide security functions to 5G users or connected by peering from the cloud-based security service into the 5G service provider's regional communications centers.

    Abstract: Systems and methods include, responsive to a request from a user for one or more Business-to-Business (B2B) applications, redirecting the request, by a cloud-based system, to an identity provider to authorize the user; displaying the one or more B2B applications that the user is authorized to access; responsive to a selection of a B2B application of the one or more B2B applications, creating a first tunnel from the B2B application to the cloud-based system; and stitching the first tunnel between the B2B application and the cloud-based system with a second tunnel between the user and the cloud-based system. The systems and methods further include, responsive to the user being unauthorized for any of the one or more B2B applications, omitting the one or more B2B applications from the displaying, such that the one or more B2B applications are invisible to the user.

    Abstract: A Content Delivery Network (CDN) includes one or more cache servers communicatively coupled to end users for providing content thereto; and one or more origin servers communicatively coupled to the one or more cache servers through a plurality of nodes, the one or more cache servers are configured to receive traffic related to the content from the one or more origin servers through the one or more nodes of the plurality of nodes, based on one or more of a push technique and a pull technique, and the plurality of nodes are configured to monitor the traffic between the one or more origin servers and the one or more cache servers in an inline manner, process the traffic for malware and data leakage based on policy, and block the traffic responsive to detection of one or more of the malware and the data leakage, prior to traffic entering the CDN.
