The disclosed computer-implemented method for anonymizing log entries may include (1) detecting a data pattern in a group of log entries documenting events performed by at least one process executing on at least one device, (2) identifying, in the data pattern, at least one data field in the log entries that contains variable data, (3) evaluating the data field containing variable data to determine whether the data field contains sensitive data, and (4) in response to determining whether the data field contains sensitive data, applying a data-anonymization policy to the data field to anonymize the log entries. Various other methods, systems, and computer-readable media are also disclosed.

Systems and methods for anonymizing log entries

Techniques for managing privacy of a network communication may be realized as a computer-implemented system, including one or more processors that store instructions, and one or more computer processors that execute the instructions to receive a first network communication, extract information from the first network communication, identify a privacy rule based on the information, generate a second network communication based on the first network communication and the privacy rule, and cause the second network communication to be sent.

The disclosed computer-implemented method for detecting modification attacks on shared physical memory may include (i) identifying a page frame of physical memory that is shared by a plurality of virtual machines, (ii) calculating a first checksum for the page frame, (iii) calculating, while the page frame is shared by the plurality of virtual machines and before any of the plurality of virtual machines writes to a page of virtual memory that is mapped to the page frame, a second checksum for the page frame, (iv) detecting a modification attack (such as a rowhammer attack) on the page frame by one of the plurality of virtual machines by detecting that the first checksum does not equal the second checksum, and (v) performing a security action in response to detecting the modification attack. Various other methods, systems, and computer-readable media are also disclosed.

Techniques for generating a virtual private container (VPC) are disclosed. In one embodiment, the techniques may be realized as a virtual container defining a self-contained software environment, comprising one or more analytic components configured to carry out specified analytic functions on data within the container, wherein the one or more analytic components are isolated to run within the self-contained software environment of the container; an interface configured to identify and authenticate a particular user and provide analysis results generated by the one or more analytic components; and a gateway configured to receive data from one or more secure data sources external to the virtual container and associated with the particular user for use by the one or more analytic components.

A computer-implemented method for digitally signing executables with reputation information is disclosed. This method may include (1) receiving a request for a reputation certificate for an executable file, (2) identifying reputation information associated with the executable file, (3) generating a digitally signed reputation certificate for the executable file that includes at least the reputation information associated with the executable file, and then (4) providing the reputation certificate in response to the request.

Knowledge of a module's behavior when the module's reputation is formed is obtained. If the module's behavior changes, this change is detected. In one embodiment, upon a determination that the module's behavior has changed, the module's original reputation is lost. In this manner, malicious trusted modules are detected and defeated.

Software reputation establishment and monitoring system and method

Application authorization management is provided without installation of an agent at an operating system level. A component runs outside of the operating system, in an AMT environment. AMT is utilized to examine the operating system for applications. Identified applications are checked against a whitelist or a blacklist. Responsive to determining that an identified application is not authorized, AMT is used to redirect input/output requests targeting the application to an alternative image, which can, for example, warn the user that the application is not authorized.

Agentless enforcement of application management through virtualized block I/O redirection

Various other methods and systems are also disclosed.

Systems and methods for providing secure access to local network devices

A method includes creating a virtual machine including a remote file system, a file system service, and a security application. Access to the remote file system is restricted with the security application upon an unknown malicious code outbreak. The more that is known about the threat, the more precise are the restrictions placed upon the file system thus reducing the impact on users of the file system to an absolute minimum.

Virtual machine file system restriction system and method

A digitally signed unknown application from a software publisher having a reputation is assigned the reputation of the software publisher. In this manner, software publishers who have an established reputation of publishing applications are allowed to rely on their existing reputation when releasing a new application. By quickly assigning reputations to new applications, users executing the new applications for the first time are provided timely recommendations on the quality, e.g., trustworthiness, of the applications they wish to run.
