Leveraging standard protocols to interface unmodified applications and services
Some embodiments provide a method for enforcing policies for authorizing API (Application Programming Interface) calls to an application operating on a host machine. The method receives a request to authenticate a client attempting to gain access to the application, and authenticates the client based on a first set of parameters associated with the request. Using a second set of parameters associated with the request, the method evaluates a set of one or more policies associated with a set of one or more API calls to the application. Based on the evaluated policies, the method defines a third set of one or more authentication field parameters that control the API calls that the client is authorized to make to the application. The method sends an authentication reply message with the defined third set of authentication field parameters in order to control the API calls that the client is authorized to make. |

Detecting malicious components using commit histories
Embodiments detect malicious code in distributed software components. A detector element references a source code repository (e.g., open source, commercial) containing lines of various files of a distributed artifact.

A risk assessor element receives from the detector element, results identifying those lines and/or files for which no VCS commit history is available. The risk assessor then references code features (e.g., file extension, security-critical API calls) in the results, to generate a probability of the malicious nature of the source code lacking VCS commit history information. An analysis report including this probability and additional relevant information, is offered to a user to conduct further manual review (e.g., to detect false positives attributable to benign/legitimate source code modification). |

Field-assembled wall and flooring systems
Described herein are methods for installing field-assembled flooring systems wherein the underlayment is a hybrid design that includes a combination of structural board and cementitious product. The hybrid design is configured to reduce or eliminate the curing time requirement after pouring the cementitious product (e.g., gypsum concrete). The field-assembled flooring systems can reduce or eliminate the chances of the onset of mold due to high moisture levels by removing the cementitious product from the prone areas and replacing it with structural boards. The structural boards (e.g., cellulose fiberboards) can be installed in non-critical areas such as underneath cabinets, around the perimeter of the floor, under bathtubs, in non-walk-in closets, anywhere drywall reaches the floor, or the like. |
