  • Patent number: 10863410
    Abstract: Methods, non-transitory computer readable media, session director apparatuses, and network traffic management systems that facilitate packet data network (PDN) service slicing with microsegmentation in an evolved packet core are disclosed. With this technology, a create session request (CSR) general packet radio service (GPRS) tunneling protocol (GTP) control (GTP-c) message is intercepted. A lookup key is then determined based on content of the intercepted CSR GTP-c message. A PDN gateway (PGW) identifier for a PGW is obtained using a slice name obtained using the lookup key. The intercepted CSR GTP-c message is modified to include the obtained PGW identifier. Subsequently, the modified CSR GTP-c message is steered based on the obtained PGW identifier, such as directly to the PGW or to a serving gateway (SGW) module associated with the PGW.

  • Patent number: 10721269
    Abstract: Client requests for server resources are received by a network traffic management device (NTMD). The NTMD initially responds to the client requests on behalf of the associated servers. The initial responses include client side language scripts for execution by the clients. Executing the scripts causes the clients to resend their initial requests identified as a potential attack by the NTMD along with information indicating the client's legitimacy, such as the result of a computational JavaScript challenge. The NTMD receives the resent initial request, determines it was sent from a legitimate requestor and is therefore not an attack, and forwards it to the associate server.

  • Patent number: RE48382
    Abstract: A method and system for improving the security and control of internet/network web application processes, such as web applications. The invention enables validation of requests from web clients before the request reaches a web application server. Incoming web client requests are compared to an application model that may include an allowed navigation path within an underlying web application. Requests inconsistent with the application model are blocked before reaching the application server. The invention may also verify that application state data sent to application servers has not been inappropriately modified. Furthermore, the invention enables application models to be automatically generated by employing, for example, a web crawler to probe target applications. Once a preliminary application model is generated it can be operated in a training mode. An administrator may tune the application model by adding a request that was incorrectly marked as non-compliant to the application model.
