Abstract: A computer implemented method, data processing system, and computer program product for monitoring system events and providing real-time response to security threats. System data is collected by monitors in the computing system. The expert system of the present invention compares the data against information in a knowledge base to identify a security threat to a system resource in a form of a system event and an action for mitigating effects of the system event. A determination is made as to whether a threat risk value of the system event is greater than an action risk value of the action for mitigating the system event. If the threat risk value is greater, a determination is made as to whether a trust value set by a user is greater than the action risk value. If the trust value is greater, the expert system executes the action against the security threat.

Abstract: A data processing system, method, and product are disclosed for automatically configuring IP security tunnels. A security policy specification format is established that is capable of being utilized by any one of multiple different operating systems and any one of multiple different machine types. An IP security tunnel is automatically configured utilizing the security policy specification format.

Abstract: A system and method for dynamically determining a CRL location and protocol. CRL location names and protocols are retrieved from a digital certificate data structure which includes a network servers that contain the CRL file. A determination is made as to whether any of the servers reside in the current domain, in which case the server is used because the data is more secure. If no locations are within the current domain, Internet servers outside the current domain are analyzed. Security parameters may be established that restrict which Internet servers can be used to retrieve the data. The security parameters may also include which access methods may be used to retrieve data since some access methods provide greater security than other access methods. A security parameter may also be based upon both the access method and the name, or address, of the Internet server.

Abstract: A system and method for providing multiple virtual private networks from a computer system. The computer system communicates with a remote computer system in order to allow encrypted data traffic to flow between the respective systems. Two phases are used to authenticate the computer systems to one another. During the first phase, digital certificates or pre-shared keys are used to authenticate the computer systems. A phase 1 ID rules list contains authentication rules for local-remote computer pairs. During the second phase, a hash value is used to authenticate the computer systems and a security association payload is created. The remote system's IP address is used for connecting. The phase 1 ID rules list corresponds to one or more phase 2 ID rules lists. If the remote ID is not found in the phase 2 ID rules list, a default rule is used based upon the phase 1 ID rules list.

Abstract: A method, network system and computer program product for establishing a server node in a virtual private network with a single tunnel definition and a single security policy for a plurality of tunnels associated with a group name. In one embodiment, a method comprises the step of configuring a group database in the server node. The group database in the server node comprises the group name and a list of members associated with the group name. The method further comprises configuring a rules database in the server node. The rules database associates the group name with a particular security policy. The method further comprises configuring a tunnel definition database in the server node. In the tunnel definition database, the remote ID is defined as the group name. In another embodiment of the present invention, the list of members associated with the group name comprises a non-contiguous list of ID types.

Abstract: A method and apparatus for use in data processing system for selecting rules to filter data for a tunnel. A request is received to create a tunnel to another data processing system. A granularity of information about the data processing system is identified to form an identified granularity. The identified granularity of the information about the data processing system is used to select a rule, which matches the identified granularity. This rule is placed in a filter, wherein the filter associates data packets with the tunnel.

Abstract: A system and method for providing multiple virtual private networks (VPNs) from a computer system. Configuration information is maintained for connections, or tunnels, established between a local computer system and a number of remote computer systems. The configuration information includes information about the endpoints, or local-remote computer pairs, policies used to determine preferred access methods for connecting a given pair of computers, pre-shared keys, and digital certificates for providing keys to encrypt and decipher data. A local-remote pair is selected from an endpoints table. A policy corresponding to the selected local-remote pair is selected determining the access method(s) to be attempted in securely connecting the two computer systems. If an access method uses a digital certificate, the corresponding information is retrieved from a digital certificate table. The decision whether to check the digital certification has been revoked is stored in the endpoints table.

Abstract: A method of securing data traffic between a local and remote host systems is provided. The method includes autogenerating a filter having rules associated with a defined tunnel. The filter rules are used to permit or deny acceptance of transmitted data by the host system and to direct traffic to the tunnel. The tunnel, on the other hand, is used to keep data confidential. The method further includes autogeneration of a counterpart tunnel and associated filter to be used by the remote host when in communication with the local host. The method further autogenerates a new filter to reflect changes to any one of the tunnels and autodeactivates the filter associated with a deleted tunnel.
