  • Methods, systems, and computer readable media for zero trust network access (ZTNA) testing using test system with simulated or emulated identity provider
    Patent number: 12452286
    Abstract: A method for ZTNA testing using a simulated or emulated IdP includes generating and transmitting, from an emulated client implemented by a network traffic emulation platform and to a server, an emulated application traffic message. The method further includes receiving, from a PEP under test, a message redirecting the emulated client to a simulated or emulated IdP and including an authentication request. The method further includes generating, by the simulated or emulated IdP, an authentication response and providing the authentication response to the emulated client. The method further includes providing, to the PEP under test, a response to the authentication request from the PEP under test. The method further includes receiving a response including an authenticated cookie from the PEP under test, generating and transmitting, to the server via the PEP under test, a request including the authenticated cookie, and receiving a response from the server.

  • Methods, systems, and computer readable media for zero trust network access (ZTNA) testing using application-independent authentication profiles
    Patent number: 12438879
    Abstract: A method for ZTNA testing using application-independent authentication profiles includes providing, at a network traffic emulation platform, user-selectable application flows for generating emulated application traffic to send to an application and providing application-independent authentication profiles for emulating authentication messaging of different ZTNA systems. The method further includes selecting one of the application flows and receiving, at the network traffic emulation platform, user selection of one of the application-independent authentication profiles. The method further includes generating and transmitting emulated authentication traffic to a ZTNA system according to the selected authentication profile, and, in response to successful completion of exchanges required by the authentication profile, generating and transmitting emulated application traffic to a network application according to the user-selected application flow.
