A method and system for configuring a data change filter in a virtualized environment are provided. A data change filter is installed in a hypervisor of a virtualization host, where the hypervisor executes a virtual machine. The data change filter intercepts data change operations from the virtual machine. The hypervisor includes a certificate management service that stores a private certificate for the data change filter and a public certificate for a replication processing service. The data change filter retrieves the certificates from the certificate management service, establishes an authenticated network connection with the replication processing service using the certificates, and sends the intercepted data change operations to the replication processing service over the authenticated connection. The system enables secure replication of data changes in virtualized environments.

A procedure and system for configuring a data change filter in a virtualized environment are provided. The data change filter is installed in a hypervisor on a virtualization host, where the hypervisor runs a virtual machine. The data change filter intercepts data change operations from the virtual machine. The hypervisor includes a certificate management service that stores a private certificate for the data change filter and a public certificate for a replication processing service. The data change filter retrieves the certificates from the certificate management service, establishes an authenticated network connection with the replication processing service using these certificates, and sends the intercepted data change operations to the replication processing service over this authenticated connection. This system enables secure replication of data changes in virtualized environments.

Authentication of network-based virtual machine replication is provided. A method and system for configuring a data change filter in a virtualized environment. A data change filter is installed in a virtual machine hypervisor of a virtualized host, wherein the virtual machine hypervisor executes a virtual machine. A data change filter intercepts data change operations from the virtual machine. The virtual machine hypervisor includes a certificate management service that stores a private certificate for the data change filter and a public certificate for the copy processing service. The data change filter retrieves the certificate from the certificate management service, establishes an authenticated network connection with the replication processing service using the certificate, and sends the intercepted data change operation to the replication processing service over the authenticated connection. The system enables secure replication of data changes in a virtualized environment.

A peripheral sharing device for supporting secure copy-paste operations between hosts comprising: a plurality of copy-emulators and a plurality of paste emulators, configured cach to be connected to a copy-paste driver, wherein cach copy-paste driver is running on one of a plurality of hosts that are connected to the peripheral sharing device, and the copy-paste driver is configured to fetch or store clipboard objects from the clipboard of the corresponding host, a security bridge that is configured to securely pass clipboard objects between pairs of copy emulator and paste emulator. The security bridge performs security operations, such as, enforce unidirectional data transfer of the clipboard object, monitor the clipboard object and enable or disable the copy-paste operation according to a set of security rules; enable or disable the copy-paste operation according to security policy, analyze clipboard object traffic to detect cybersecurity events, locking suspicious peripheral sharing devices, and preventing clipboard object transfer between pairs of copy-paste controllers according to security rules. The copy emulator receives the clipboard object from the copy-paste driver of a first host, transfer the clipboard object to the security bridge and conditioned upon passing the security conditions the security bridge transfer the clipboard object to the paste emulator that further pass the clipboard object to a second computer's copy-paste driver.

The invention discloses an online and offline coexisting digital certificate service system and method. The system comprises an offline signing and issuing subsystem, a cross-domain secure transmission module, a special one-way isolation device, an online application subsystem and an online application service SDK interface module. According to data interaction between the offline signing and issuing subsystem and the online application subsystem, automatic real-time one-way transmission from the offline subsystem to the online subsystem is achieved through a cross-domain secure transmission module and a special one-way isolation device, and one-way transmission from the online subsystem to the offline subsystem is achieved in a manual secure copy offline mode. Compared with the prior art, the invention not only meets the application requirement of offline certificate signing and issuing of high-security sensitive business, but also provides convenient online certificate application and online certificate application services, realizes balance between security and convenience of digital certificate services, and provides a solid guarantee for information security of a power monitoring system.
