Abstract: A method and a related system for a protection against unauthorized file encryption in a file system may be provided. The method may comprise providing an anti-ransomware file access unit, determining, by the anti-ransomware file access unit, an entropy value for a portion of a file to be written to the file system, and upon determining that the entropy value is equal or above a threshold value, performing a copy-on-write process to the file to be written, whereby the file is written to a copy-on-write storage area.

Abstract: A method for de-duplicating updates in virtual machines (VMs) is provided that may be executed on a host computer u a hypervisor. Client VMs are derived from a base image, and the method includes: creating a temporary virtual machine, updating the temporary virtual machine, identifying modified blocks of the updated temporary virtual machine, and identifying files associated with the modified blocks. Moreover, the method includes determining block identifiers of matching files of a VM corresponding to identified files of the updated temporary VM, moving block content of blocks relating to the determined block identifiers from its initial location to a free location within the client VM if the block content and the matching files are not identical in the client virtual machine and the temporary VM, and de-duplicating content within the client VM, generating a complete bootable image, and replacing the base image by the temporary VM.

Abstract: Embodiments include method, systems and computer program products for anonymous secure socket layer (SSL) certificate verification in a trusted group. In some embodiments, a device associated with a user receiving a web server certificate from a web server. A message that includes the web server certificate and associated universal resource locator (URL) may be encrypted using a group key and a proxy key. The message may be transmitted to a proxy server. An anonymized request based on the message may be received from the proxy server. An encrypted response may be generated and transmitted to the proxy server. Encrypted and anonymized responses from members of a trusted group may be received. The responses may be processed and an action associated with the web server certificate may be facilitated.

Abstract: An approach for simultaneous multithreading in a processor. The approach comprises measuring SMT-performance value of a software code and measuring non-SMT-performance value the software code, comparing the SMT-performance value with the non-SMT performance value and dispatching the software code for execution mode by the processor based on the comparison, wherein the execution mode comprises SMT-mode and non-SMT-mode of the processor.
