Method and system for user induced password scrambling
A system, method, and computer-readable medium are provided to protect passwords for computer applications by providing a user-triggered password scrambling mechanism. Scrambling is enabled with a user configurable character within the password to be a trigger. Once triggered, a user can enter several incorrect password strings without fear of being locked out of the system.

Approach for a controllable trade-off between cost and availability of indexed data in a cloud log aggregation solution such as splunk or sumo
Systems and methods for classification of log data at the source into sets of critical and non-critical data.

In the event that non-critical data is required for troubleshooting or analysis, the non-critical data may be indexed dynamically on request. Because the non-critical data is stored at the cloud-based log aggregation system, it may be quickly indexed and added to the critical data, without additional consumption of bandwidth or delays due to transmission. Dynamic selection and classification of critical and non-critical data may thus allow an enterprise to balance costs and availability of indexed data. |
