Methods, systems, and computer-readable media for renaming a database table with minimized application downtime are disclosed. A database receives a table rename request for a table having a first table name. Routing metadata comprises a mapping of the first table name to a table identifier and a mapping of the table identifier to one or more partitions. The table rename request indicates a second table name. The database generates updated routing metadata responsive to the table rename request. The updated routing metadata comprises a mapping of the second table name to the table identifier and the mapping of the table identifier to the one or more partitions. The database receives, from a client application, one or more access requests indicating the second table name. The database routes the one or more access requests to the one or more partitions based at least in part on the updated routing metadata.

Renaming a database table with minimized application downtime

A computing resource service receives a request to access the service and perform various actions. In response to the request, the computing resource service obtains a set of active policies that are applicable to the request. As a result of the service determining that the set of active policies fail to provide sufficient permissions for fulfillment of the request, the service determines if an enforcement policy is available that is applicable to the request. The service evaluates the request using the enforcement policy such that if the enforcement policy includes permissions sufficient for fulfillment of the request, the request is fulfilled.

Access control monitoring through policy management

A policy/resource decommissioning service determines whether a resource has been inactive for a period of time greater than at least one period of time threshold for decommissioning. If the resource has been inactive greater than a first period of time threshold, the service disables the resource such that requests to access the resource are denied. If the resource has been inactive for a period of time greater than a second threshold, longer than the first period of time threshold, the service archives the resource. The service deletes the resource if the inactivity period of the resource is greater than a third period of time threshold, where the third period of time threshold is longer than the first and the second period of time thresholds.

Automatic account resource and policy decommissioning

Techniques for self-learning access control policies are disclosed herein. A set of security policy modification recommendations is produced based on set of effective permissions and also based on a set of requests for access subject to that set of effective permission. Each policy modification recommendation is configured to alter the set of effective permissions by performing one or more actions altering one or more of the effective permissions. A selected policy modification recommendation is provided that is configured to produce a modified set of effective permissions.

Self-learning access control policies

Concepts and technologies are described herein for providing enhanced Completely Automated Public Turing tests to Tell Computers and Humans Apart ('CAPTCHAs'). According to some of the concepts and technologies disclosed herein, a CAPTCHA service may be configured to generate CAPTCHAs enhanced with watermarks and/or other enhancements. The CAPTCHA service may provide the enhanced CAPTCHAs to user services, such as Websites, Web services, and other services that utilize or are capable of utilizing CAPTCHAs as a security feature. The watermarks and/or other enhancements may contain information associated with users of the user services so that the enhanced CAPTCHAs are more difficult to break by unauthorized entities, including automated programs such as 'bots.' According to other concepts and technologies disclosed herein, a CAPTCHA breaking service is provided.

Enhanced captchas

A workbook includes a spreadsheet having cells arranged in columns and rows. The cells include input cells and output cells. The output cells include a formula to be calculated. Calculation of the spreadsheet is divided into multiple tasks. The tasks are assigned among computing nodes within a computing cluster for concurrent calculation of the spreadsheet.
