Abstract: Some embodiments provide or utilize technology which increases the security of network authentication operations, such as Kerberos operations, New Technology LAN Manager operations, or other network authentication operations which utilize security tickets or security tokens or both. In some embodiments, a user machine (also known as a client machine) receives an authentication data structure (ADS) which includes one or more security tickets or security tokens or both. Embodiments constrain the ADS according to at least one security requirement, such as a volatile-memory-only constraint, a secured-memory-only constraint, or a multilayer encryption constraint. Embodiments also transmit the ADS from the machine as a part of performing the network authentication service. Some embodiments inhibit virtual memory, or memory dumping, or both. Some embodiments bind the ADS to the user machine, and some embodiments limit ADS usage counts.

Abstract: Techniques are described herein that are capable of using a requestor identity to enforce a security policy on a network connection that conforms to a shared-access communication protocol. A request to create the network connection to a network resource is received. The network connection is associated with the requestor identity, which identifies a requesting entity associated with the request, by associating the request with the requestor identity and further by associating the network connection with the request. A determination is made whether the requesting entity is authorized to access the network resource based at least in part on a permission that is indicated by the security policy. Based at least in part on the permission indicating that the requesting entity is authorized to access the network resource, the network connection to the network resource is created.

Abstract: A computing system is configured to perform zero-trust domain name resolution. The computing system includes applications coupled to a zero-trust client. The zero-trust client is configured to receive requests for IP addresses corresponding to endpoint identifiers for internet connected endpoints. The zero-trust client includes a synthetic DNS service configured to identify synthetic IP addresses for the endpoint identifiers. The zero-trust client provides the synthetic IP addresses for the endpoint identifiers to the applications. The zero-trust client sends data traffic from the applications to a zero-trust service with the synthetic IP addresses where corresponding synthetic IP addresses are correlated to the endpoint identifiers at the zero-trust service.

Abstract: Filesystem driver software can receive a file access request indicating that an application process is requesting to access a target file in a filesystem, Network filter driver software can receive a connection establishment request indicating that the application process running on the processing apparatus is requesting to establish a connection over a network with a target endpoint. According to the present disclosure, one or both of: a) the filesystem driver software is configured to grant or deny the file access request in dependence on state information from the network filter driver software, and/or b) the network filter driver software is configured to grant or deny the connection establishment request in dependence on state information from the filesystem driver software.
