Abstract: Techniques for dynamic throttling of scan requests for multiple scanners in a cluster of nodes are described. An apparatus may comprise a dynamic throttling service component for executing the dynamic throttling of scan requests for the multiple scanners in the cluster of nodes. The dynamic throttling service component operative to estimate, by the scanner proxy, a resource limit count value representative of resource capacity for servicing scan requests for each one of the multiple scanners in the cluster of nodes; detect a first scan request exceeds the resource limit count value for a first scanner; dynamically throttle each subsequent scan request for the first scanner in response to the first scan request exceeding the resource limit count value; and revise the resource limit count value, by the scanner proxy, for the first scanner.

Abstract: Method and system for access based directory enumeration is provided. When a directory is enumerated for a first time, user credentials are verified against an access control list (ACL) entry that is referenced by an ACL inode (referred to as Xnode). The Xnode number is obtained from a file handle for a directory entry. The verification is recorded in a data structure that stores the Xnode identifier and user identifier. When the directory is enumerated again, the data structure is used to verify that the user has been validated before, instead of loading and checking against an ACL entry.

Abstract: Techniques for maintaining dynamic configuration information of a multi-host off-cluster service on a cluster are described. An apparatus may comprise a dynamic configuration validation service component to execute to execute a dynamic configuration validation service for scanning files in a cluster of nodes. The dynamic configuration validation service component operative to validate a scanner version for each one of multiple scanners for scanning a file in a cluster of nodes, maintain the scanner version in a list of valid scanner versions for the multiple scanners, and scan the file by one of the one of multiple scanners having the scanner version contained in the list of the valid scanner versions.
