The disclosed computer-implemented method for generating device-specific security policies for applications may include (1) installing, onto a computing device, an application requested by the computing device, (2) while the application is running on the computing device, monitoring interactions between the application and a computing environment in which the computing device operates to identify (A) computing resources within the computing environment required by the application and (B) potential security concerns related to the application within the computing environment, and then (3) generating, based on the monitored interactions, a set of device-specific security policies to enforce for the application while the application runs on the computing device that allow the application to access the required computing resources while mitigating the potential security concerns. Various other methods, systems, and computer-readable media are also disclosed.

Techniques of obfuscation for enterprise data center services are disclosed. In one embodiment, the techniques may be realized as a system for obfuscation comprising one or more processors. The one or more processors may be configured to receive a command from at least one of a user and an application and determine whether the command is authorized. If the command is determined to be unauthorized, the one or more processors may be further configured to generate a rewritten output of the command that is different from an original output of the command and return the rewritten output in response to the command.

A processor-based method to defeat file and process hiding techniques in a computing device is provided. The method includes generating one of a path permutation, a symlink, or an address, for a path to open or obtain status of a tool or function in a library in a mobile computing device and making an open or status call for the tool or function, using the one of the path permutation, symlink or address. The method includes avoiding a pattern match and blocking, by an injected library, of the open or status call, the avoiding being a result of making the open or status call using the path permutation, symlink or address.

A computer-implemented method for evaluating electronic control units within vehicle emulations may include (1) connecting an actual electronic control unit for a vehicle to a vehicle bus that emulates network traffic rather than actual network traffic generated by operation of the vehicle, (2) manipulating input to the actual electronic control unit to test how safely the actual electronic control unit and the emulated electronic control unit respond to the manipulated input, (3) detecting an output from the actual electronic control unit that indicates a response, from the actual electronic control unit, to manipulating the input, and (4) evaluating a safety level of at least one of the actual electronic control unit and the emulated electronic control unit based on detecting the output from the actual electronic control unit. Various other methods, systems, and computer-readable media are also disclosed.
