Abstract: In an example, a device for operating a switching converter is configured to receive a composite command duty cycle value. The device is further configured to generate an effective duty cycle value based on a voltage at a switching node. The device is further configured to generate a duty cycle mismatch value using the composite command duty cycle value and the effective duty cycle value so as to generate a plurality of duty cycle mismatch values. Each duty cycle mismatch value of the plurality of duty cycle mismatch values corresponds to a candidate natural frequency value of the converter. The device is further configured to output a candidate natural frequency value of the converter that corresponds to a maximum duty cycle mismatch of the plurality of duty cycle mismatch values.

Abstract: Securing an endpoint against exposure to unsafe content includes encrypting files to prevent unauthorized access, and monitoring an exposure state of a process to potentially unsafe content by applying behavioral rules to determine whether the exposure state is either exposed or secure, where (1) the process is initially identified as secure, (2) the process is identified as exposed when the process opens a network connection to a URL that is not internal to an enterprise network of the endpoint and that has a poor reputation, (3) the process is identified as exposed when it opens a file identified as exposed, and (4) the process is identified as exposed when another exposed process opens a handle to the process. Access to the files may be restricted when the process is exposed by controlling access through a file system filter that conditionally decrypts files for the process according to its exposure state.

Abstract: On an endpoint that encrypts local files to protect against data leakage and other harmful malware events, newly detected files are dynamically encrypted when they are detected as long as the endpoint is not compromised. If a compromised state is detected, the newly detected file will not be added to the encrypted files until the endpoint can be remediated and the compromised state resolved.

Abstract: A portable encryption format wraps encrypted files in a self-executing container that facilitates transparent, identity-based decryption for properly authenticated users while also providing local password access to wrapped files when identity-based decryption is not available.

Abstract: An endpoint encrypts local files with a key to protect file contents. If the endpoint or processes on the endpoint becomes exposed to potentially harmful locations or resources, the key can be revoked to prevent access to encrypted files on the endpoint. In order to facilitate continued operation of the endpoint, files that are currently open can be encrypted with a second key so that the corresponding data is isolated from the other encrypted files while remaining accessible to current users.

Abstract: Rules are applied at a network perimeter to outbound network communications that contain file attachments. The rules may, in a variety of circumstances, require wrapping of an outbound file from the endpoint in a portable encrypted container. The network perimeter may be enforced locally at the endpoint, or at any network device between the endpoint and a recipient.

Abstract: Securing an endpoint against malicious activity includes encrypting a plurality of files on an endpoint to prevent unauthorized access to the plurality of files, receiving a request to access a file from a process executing on the endpoint, decrypting the file for the process, and monitoring a security state of the process. If the security state becomes a compromised state, a technique involves maintaining access to any open files (including the file decrypted for the process), prohibiting access to other files, and initiating a remediation of the process by facilitating a restart of the process. If the remediation is successful, access by the process to the plurality of files may be restored.
