Disclosed herein are methods, systems, and processes to secure internal services in an appliance. A service call initiated by a client process of a client is intercepted. The service call is a request for an internal service provided by a server. The client and the server are deployed in an appliance. The service call includes an identifier, and the identifier identifies the internal service. If one or more rules are specified for the identifier, attribute(s) of at least one specified and/or defined rule are processed. The service call is then forwarded to the server if the processing indicates that the forwarding the service call is allowable.

Various systems, methods, and processes to optimize input/output (I/O) fencing operations in systems that implement coordination points are presented. A matrix is generated. The matrix includes information indicating the accessibility of one or more coordination points by a node. The method then transmits the matrix to one or more other nodes. In addition, in response to determining that a node is no longer part of a sub-cluster, another node in the sub- cluster is designated as a racer node. The racer node accesses a matrix, and the matrix includes information to determine whether a majority of coordination points in a cluster are accessible by nodes in the sub-cluster. Based on the accessing, a determination is made that the information indicates that the majority of coordination points are accessible by the nodes. The information is then broadcasted. Further, in response to a cluster being partitioned into multiple network partitions, a determination is made, using a first node in a first network partition, whether the first node wins one or more coordination points. The determination of the first node is then transmitted to a second node in the first network partition. Further, another determination is made using the second node whether the second node wins one or more other coordination points other than the one or more coordination points won by the first node.

SYSTEM AND METHOD FOR CENTRALIZED CONFIGURATION AND AUTHENTICATION
A system and method for efficiently obtaining user configuration information for a given device. Multiple devices are deployed in an environment and may be storage appliances. A directory service and an authentication service may be used to determine whether a login session attempt on a deployed device is successful. An identity and access manager (IAM) is used to for this determination and to communicate with the directory service and the authentication service. A device of the one or more of the deployed devices does not store user configuration information. Responsive to an attempted login by a user, the device mimics the existence of the user and generates a request for directory lookup and authentication for the user which is conveyed to an external device. If a positive response is received in response to the request, the user is permitted to login to the device and a session is created for the user.
