Abstract: One or more embodiments provide a system and method for DNS that is resistant to losses of network connections. In some particular embodiments, DNS servers are operated to maintain consistency of DNS records between the multiple master servers in response to connection failure. Each master DNS server monitors network connectivity by periodically testing network connections of the master server (e.g., to other master servers) to determine whether the master DNS is isolated in a manner that prevents updates from being distributed between the master DNS servers. In response to detecting network isolation of the master DNS server, the master DNS server is configured to enter the isolation mode, in which the master DNS monitors the status of connections and takes appropriate actions to update and/or recover DNS data when connections are restored.

Abstract: According to one or more embodiments, a telecommunication system includes a call routing circuit configured to receive and route calls and data transmissions from a plurality of telecommunication devices. The telecommunication system also includes a processing circuit for monitoring business and personal use of telecommunication devices associated with a client account. The processing circuit is configured to maintain a log of calls and data transmissions routed by the call-routing circuit for a the plurality of telecommunication devices. The processing circuit is further configured to use a set of classification functions in a policy of the client account to determine whether each of the identified first set of calls and data transmissions are business related or personal based on characteristics of each of the first set of calls and data transmissions.

Abstract: Systems, devices or methods provide for control of sensitive data in a computer system that includes at least one central server communicatively-coupled to a plurality of client computers. A particular method relates to the execution of software code on the at least one central server to monitor data communications of the plurality of client computers for sensitive data. A subset of the data communications is restricted when sensitive data is detected. Configuration data is provided to each of the plurality of client computers. Software code is executed on each of the plurality of client computers to detect accesses to sensitive data by one or more applications running on a client computer. Actions of the one or more applications running on a client computer are monitored to determine whether or not a trigger event has occurred. In response to determining that the trigger event has occurred, a notification is sent.
