The present invention provides a technique for securely implementing port-based authentication on a shared media port in an intermediate node, such as a router. To that end, the invention provides enhanced port-based network access control that includes client-based control at the shared media port. Unlike previous implementations, the port does not permit multiple client nodes to access a trusted subnetwork as soon as a user at any one of those nodes is authenticated by the subnetwork. Instead, port-based authentication is performed for every client node that attempts to access the trusted subnetwork through the shared media port. As such, access to the trusted subnetwork is not compromised by unauthenticated client nodes that “piggy-back” over the shared media port after a user at another client node has been authenticated by the trusted subnetwork.

The second subsystem is a security enhanced database management system. In documents the system allows different user privilege requirements on the document as a whole as well as on pages, paragraphs, sentences, words, and / or letters of a word. A history of document changes is maintained to provide an audit trail after the fact of who did what changes, where those changes were made and when those changes were made.

The invention provides a government affair data storage and query method and system based on a block chain double-chain structure. The government affair data storage method based on the block chain double-chain structure comprises the steps that a client uploads the data to a proxy server; the proxy server sends a data storage request to the identity chain and verifies the user identity and the data storage request; the identity chain verifies the identity of the user who makes the request and the storage operation authority, and returns a verification result to the proxy server; if the verification does not pass, the proxy server sends a data storage rejection request to the client; if the verification passes, the proxy server submits a data storage request to a service data chain, and the service data chain completes a consensus process according to the data storage request of the client and stores the data related information in a block chain system state database; and the service data chain feeds back a storage result to the client through the proxy server.

During power up initialization, security data such as passwords and other sensitive data which are stored in a lockable memory device are read and copied to protected system management interrupt (SMI) memory space, subject to verification by code running in the SMI memory space that the call to write the security data originates with a trusted entity. Once copied to SMI memory space, the security data is erased from regular system memory and the lockable storage device is hard locked (requiring a reset to unlock) against direct access prior to starting the operating system. The copy of the security data within the SMI memory space is invisible to the operating system. However, the operating system may initiate a call to code running in the SMI memory space to check a password entered by the user, with the SMI code returning a “match” or “no match” indication. The security data may thus be employed after the lockable memory device is hard locked and the operating system is started.

Unauthenticated client access to an application (e.g., a SaaS-based web application) that employs unauthenticated API endpoints is monitored and protected by an access control system and method that leverages a neural network. The neural network is trained to recognize user behaviors that should be deemed to be “inappropriate” according to a policy. Using the neural network, the system provides effective discrimination with respect to unauthenticated user behavior, and it enables access controls to be more effectively enforced with respect to users that are not using the application according to an enterprise security policy. By training the neural network to recognize pattern(s) behind regular user behavior, the approach enables robust access control with respect to users that are unauthenticated. More generally, the approach facilitates access control based in whole or in part on API interactions with an application where the identity of the individuals making that access are unknown or necessarily ascertainable.
