Abstract: Aspects of the invention include systems and methods configured to prevent masquerading service attacks. A non-limiting example computer-implemented method includes sending, from a first server in a cloud environment, a communication request comprising an application programming interface (API) key and a first server identifier to an identity and access management (IAM) server of the cloud environment. The API key can be uniquely assigned by the IAM server to a first component of the first server. The first server receives a credential that includes a token for the first component and sends the credential to a second server. The second server sends the credential, a second server identifier, and an identifier for a second component of the second server to the IAM server. The second server receives an acknowledgment from the IAM server and sends the acknowledgment to the first server.

Abstract: An approach for protecting container image and runtime data from host access may be presented. Container systems have allowed for more efficient utilization of computing resources, removing the requirement of a hypervisor, and packaging all necessary dependencies within an application. Preventing host access to container image and runtime data can be advantageous for a multitude of reasons. The approach herein may include, flattening a plurality of root file system of a one or more container images into a single layer. The approach may also include generating a container base image for each of the one or more flattened root file system. The approach may include encrypting each of the generated container base images with the flattened root file system.

Abstract: Aspects of the invention include splitting a first file retrieved from a first cloud computing environment of a hybrid cloud computing environment into multiple chunks. A respective chunk signature is calculated for each chunk of the multiple chunks, wherein the calculation is based at least in part on static metadata and the dynamic metadata retrieved from the first file. The respective chunk signatures are compared to chunk signatures from a metadata repository to identify a duplicate second file, wherein the first file is a variant of a second file stored in a second cloud computing environment of the hybrid cloud computing environment. Either the first file or the second file is selected as candidate for deletion. The candidate for deletion is deleted.

Abstract: Aspects include providing isolation between a plurality of containers in a pod that are each executing on a different virtual machine (VM) on a host computer. Providing the isolation includes converting a data packet into a serial format for communicating with the host computer. The converted data packet is sent to a router executing on the host computer. The router determines a destination container in the plurality of containers based at least in part on content of the converted data packet and routes the converted data packet to the destination container.

Abstract: A method for inhibiting replication of reverse transcriptase dependent virus in plant or animal cells, comprising the step of administering to said cells a compound that depletes the intracellular pool of deoxyribonucleoside phosphate in an amount effective to inhibit replication of said virus. Hydroxyurea is one such suitable compound. Also disclosed is a method for producing incomplete reverse- transcriptase dependent viral DNA, by administering a deoxyribonucleoside phosphate-depleting drug to cells infected with such a virus.
