A media file content provider 30 sends a non-permanent copy of a media file, such as a music or video file, to a second mobile station MS 34 in response to a request from a first MS 22. The copy may be rendered non-permanent by streaming it, by encrypting it, and by appending a first instruction to automatically delete it after playing. The first MS 22 may be given an option of delivery pathways, such as cellular 76, 78, WLAN 80, or DVB-H 84. After playing, an offer is made to the second MS 34 t...

An approach for managing functionalities within a system generally involves the use of indicators, such as privileges, that are associated with the functionalities. Each functionality is associated with an indicator that is used to determine whether the associated functionality is available for use by an end user. A determination is made that one or more particular functionalities are to be associated with the response because the particular indicator is included in the set of indicators and cor...

A network for mediating the peer-to-peer transfer of digital patient medical data includes a plurality of distributed agents each associated with a health care provider and connected to a central system. Periodically the agents collect local information relating to patient medical files and/or data streams, for example diagnostic images and associated reports, and process that information into metadata files acting as pointers to the original files. The metadata files are transmitted to the cent...

Methods, systems and computer program products are provided for evaluating security of a network environment. Security data associated with an asset in the network environment collected over a first period of time is analyzed to detect security events occurring at a rate above a reference rate. Security data associated with the asset collected over a second period of time, greater than the first period of time, is analyzed to detect security events occurring at a rate below the reference rate. A...

A method for providing security for a network intrusion detection system in a provisionable network, the method comprises evaluating the system security of the provisionable network and applying a system lockdown in the provisionable network in accordance with the results of the evaluation.

A technique for protecting a computer system against malware involves distributing anti-malware data across multiple computing resources. When a local machine detects a malware instance, the local machine may then query a network resource for anti-malware data needed to at least one of identify and remediate the malware instance. The malware instance is then remediated using the anti-malware data from the network resource.

A system identifies computer worms associated with published, or otherwise, known security holes. The system uses a worm pattern developed to identify those data packets most likely to be a computer worm designed to take advantage of a particular security hole. The worm pattern includes a portion used to functionally characterize the computer worm and another portion used to provide a defense mechanism used to thwart the worm attack. In some cases, the defense action is truncating the suspected ...

An antivirus client module (114) includes a virus definitions module (312) holding information describing characteristics of files that can potentially be infected by viruses and information enabling a determination of whether a file is actually infected by a virus. The client module (114) also includes a filtering module (314) having a file information cache (410) describing characteristics of files. A file scanning module (316) can scan files to determine whether the files are infected by viru...

Detecting an attack on an authentication service. A first memory area is configured to store data relating to a plurality of requests communicated to an authentication service from a plurality of user agents. A second memory area is configured to store a predefined pattern of one or more requests. The predefined pattern characterizes an attack. A processor searches the stored data as a function of a query variable to identify at least one of the plurality of the requests communicated from at lea...

An apparatus, a method, and a computer program are provided for securing transmitted text. Once text has been produced by an application, the potential exists for an unintended third party to obtain sensitive data transmitted over computer networks. However, a parsing function can then operate either on an individual computer or on a network to scan text at an Open Systems Interconnection (OSI) Layer 1 to assist in the prevention of sensitive data transmission. By utilizing the parsing function,...
