Methods, systems, and computer program products are disclosed for protecting the security of resources in distributed computing environments. The disclosed techniques improve administration and enforcement of security policies. Allowed actions on resources, also called permissions, (such as invocations of particular methods, read or write access of a particular row or perhaps a particular column in a database table, and so forth) are grouped, and each group of permissions is associated with a role name. A particular action on a particular resource may be specified in more than one group, and therefore may be associated with more than one role. Each role is administered as a security object. Users and / or user groups may be associated with one or more roles. At run-time, access to a resource is protected by determining whether the invoking user has been associated with (granted) at least one of the roles required for this type of access on this resource.

The conformance of a network to a set of security policy statements is determined by attempting to violate the policies by routing packets through models of network elements. Policy statements specify whether a set of clients is granted or denied access to a network service offered by a set of servers. Network element models are in accordance to the element's configurable parameters and supported services, which together indicate how the element will treat packets when the element's current configuration is applied to the model. Conformance to a policy statement is determined by building a packet in accordance with the network service and a representative network-element client and server, and by attempting to move the packet from the client to the server by applying the packet to the network element models. Policy conformance is based on whether the packet reaches the service on the server. Network reconfigurations are determined for non-conformant policies.

An evidence-based policy manager generates a permission grant set for a code assembly received from a resource location. The policy manager executes in a computer system (e.g., a Web client or server) in combination with the verification module and class loader of the run-time environment. The permission grant set generated for a code assembly is applied in the run-time call stack to help the system determine whether a given system operation by the code assembly is authorized. Both code assemblies and evidence may be received from a local origin or from a remote resource location via a network (e.g., the Internet). Evidence having different levels of trust may be evaluated in combination so that a permission grant set is associated only with trusted code assemblies. The policy manager may comprise execution modules for parsing a security policy specification, generating one or more code hierarchies, evaluating membership of the received code assembly in one or more code groups, and generating a permission grant set based upon this membership evaluation.

A system and method are provided for management of access security for access by a multimodal device to a converged fixed / mobile network. An inter-technology change-off monitoring entity (ICME) is provided to monitor an inter-technology change-off of the multimodal device and to notify a policy manager of the inter-technology change-off. The policy manager looks up in a policy database, security policies applicable to the user of the multimodal device and the particular technology being used by the multimodal device. The policy manager conveys to various policy enforcement points throughout the converged fixed / mobile network the applicable security policies which take into account the user's identity and the access technology being used.

A system and method is provided for reducing the complexity and improving the performance of enforcing security restrictions on the execution of program code in a runtime environment. In a preferred embodiment, units of executable code, such as methods or functions, are classified by “security level.” Code units belonging to a “trusted” security level may call any other code unit in the runtime environment, but other security levels are restricted in the code units they can call. In a preferred embodiment, the security levels are represented by corresponding permission objects. Each permission object that is associated with a particular security level includes a numerical value that denotes that security level. Security policies can be enforced with respect to caller and callee code units by comparing numerical values of corresponding permission objects. This security level scheme also improves runtime performance by making it unnecessary to check individually-defined permissions in many cases.

A security policy manager generates a permission grant set for a code assembly received from a resource location. The policy manager can execute in a computer system (e.g., a Web client) in combination with the verification module and class loader of the run-time environment. The permission grant set generated for a code assembly is applied in the run-time call stack to help the system determine whether a given system operation by the code assembly is authorized. A permission request set may also be received in association with the code assembly. The permission request set may include a minimum request set, specifying permissions required by the code assembly to run properly. The permission request set may also include an optional request set, specifying permissions requested by the code assembly to provide an alternative level of functionality. In addition, the permission request set may include a refuse request set, specifying permissions that are not to be granted to the code assembly. The permission requests are used to filter a permission set to generate a permission grant set.

Policy information stores policy setting information and identification information of a policy in correlation with each other, the policy setting information correlating setting content of the policy with each data type information indicating whether data for which the policy is set is original data or derived data. A data information storage stores identification information of data for which a policy is set in correlation with the data and identification information of the policy attached to the data, and information for identifying that the data is the derived data. A searching unit identifies, in response to a searching request, identification information of a policy correlated to the data whose identification information is designated in the searching request, identifies whether target data of the searching request is the original data or the derived data.

Security policy manager devices are leveraged by manager objects to use highly secure user transparent communications to provide detection of questionable activities at every node, automatic collection of information related to any potential attack, isolation of the offending object with arbitrary flexibility of response (e.g. flexibly determining the level of certainty of an attack for initiation of a response in accordance with the number of nodes to be partitioned that is determined by the collected data concerning the potential attack), changing trust relationships between security domains, limiting the attack and launching offensive information warfare capabilities (e.g. outbound from the compromised node while limiting or eliminating inbound communications) in log time and simultaneously and / or concurrently in different but possibly overlapping sections or segments of a digital network of arbitrary configuration.

By utilizing the virtual machine safety policy migrating device, the automatic seamless migration of the safety policy of the safety device on the virtual machine along with the migration of the virtual migration is realized; and the manual configuration operation of a manager on the safety device because of the migration of the virtual machine is avoided, which means a lot for a large data center in which the virtual machine migrates often.

A security analytics system receives incident data (from an incident management system) and security policy information (from a security policy management system). The security analytics system evaluates these data sets against one another, preferably using a rules-based analysis engine. As a result, the security analytics system determines whether a particular security policy configuration (as established by the security policy management system) needs to be (or should be) changed, e.g., to reduce the number of incidents caused by a misconfiguration, to increase its effectiveness in some manner, or the like. As a result of the evaluation, the security analytics system may cause a policy to be updated automatically, notify an administrator of the need for the change (and the recommendation), or take some other action to evolve one or more security policies being enforced by the security policy management system.
