In the prior art of computer security by default programs are allowed to do whatever they like to other programs or to their data files or to critical files of the operating system, which is as absurd as letting a guest in a hotel bother other guests as he pleases, steal their property or copy it or destroy it, or have free access to the hotel's management resources. The present concept is based on automatic segregation between programs. This is preferably done by creating automatically an unlimited number of Virtual Environments (VEs) with virtual sharing of resources, so that the programs in each VE think that they are alone on the computer, and (unless explicitly allowed by the user) any changes that they think they made in virtually shared resources are in reality only made in their own VE, while the user preferably has an integrated view of the computer.

System and method for comprehensive general generic protection for computers against malicious programs that may steal information and/or cause damages

A system and method provide comprehensive and highly automated testing of vulnerabilities to intrusion on a target network, including identification of operating system, identification of target network topology and target computers, identification of open target ports, assessment of vulnerabilities on target ports, active assessment of vulnerabilities based on information acquired from target computers, quantitative assessment of target network security and vulnerability, and hierarchical graphical representation of the target network, target computers, and vulnerabilities in a test report. The system and method employ minimally obtrusive techniques to avoid interference with or damage to the target network during or after testing.

System and method for network vulnerability detection and reporting

A system and method for conducting electronic commerce are disclosed. In various embodiments, the electronic transaction is a purchase transaction. A user is provided with an intelligent token, such as a smartcard containing a digital certificate. The intelligent token suitably authenticates with a server on a network that conducts all or portions of the transaction on behalf of the user. In various embodiments a wallet server interacts with a security server to provide enhanced reliability and confidence in the transaction. In various embodiments, the wallet server includes a toolbar. In various embodiments, the digital wallet pre-fills forms. Forms may be pre-filled using an auto-remember component.

Methods and Apparatus for Conducting Electronic Transactions

An access system provides identity management and/or access management services for a network. An application program interface for the access system enables an application without a web agent front end to read and use contents of an existing encrypted cookie to bypass authentication and proceed to authorization. A web agent is a component (usually software, but can be hardware or a combination of hardware and software) that plugs into (or otherwise integrates with) a web server (or equivalent) in order to participate in providing access services.

Access system interface

A security management system includes a fusion engine which “fuses” or assembles information from multiple data sources and analyzes this information in order to detect relationships between raw events that may indicate malicious behavior and to provide an organized presentation of information to consoles without slowing down the processing performed by the data sources. The multiple data sources can comprise sensors or detectors that monitor network traffic or individual computers or both. The sensors can comprise devices that may be used in intrusion detection systems (IDS). The data sources can also comprise firewalls, audit systems, and other like security or IDS devices that monitor data traffic in real-time. The present invention can identify relationships between one or more real-time, raw computer events as they are received in real-time. The fusion engine can also assess and rank the risk of real-time raw events as well as mature correlation events.

Method and System for Managing Computer Security Information

A method for detecting security vulnerabilities in a web application includes analyzing the client requests and server responses resulting therefrom in order to discover pre-defined elements of the application's interface with external clients and the attributes of these elements. The client requests are then mutated based on a pre-defined set of mutation rules to thereby generate exploits unique to the application. The web application is attacked using the exploits and the results of the attack are evaluated for anomalous application activity.

System for determining web application vulnerabilities

The present invention is a security gateway system (10) positioned between an external, untrusted computing environment (16) and an internal, trusted computing environment (12) that converts mesages received from the external environment into simplified messages and converts the simplified messages into messages suitable for use on the internal environment. The conversion involves the removal of external environment transfer protocols and the reduction of the content of the messages left after removing the protocols into a simplified representation of the content to create a simplified message. The simplified representation is then converted to an internal message by converting the simplified representation to a representation appropriate to the internal environment, including to applications operating on the internal environment, and adding internal environment protocols, including transfer protocols, to the converted message. Simplified representations exist for some but not necessarily all types of content which may be received from the external environment, thus limiting the content which may be passed from the external to the internal environment.

Method and system for protecting operations of trusted internal networks

A method for protecting an operating environment on a processor from a rogue program operating on the processor comprising isolating simultaneously executing programs or operating systems is disclosed (502) Memory space for use only by the first program (306) while the first program executing is allocated (504) Communication between the first program and the computer's operating environment is accomplished through a single link employing one of several methods including using shared memory space (508), a dedicated interrupt or a dedicated I/O port (510) The monitor manages (546) a restricted operating environment for the first program (306) on the processor, the restricted operating environment preventing the first program from accessing resources on the processor except for the allocated memory space and the single communication link (516-522)

Method and system for maintaining restricted operating environments for application programs or operating systems

A method and computer program for automatically and continually extracting application protocols (i.e., defining a set of allowable or authorized actions) for any application. The method involves receiving a message from a server before it is sent or in parallel with sending to a client. The message may be in response to a specific request for it from the client. The program then extracts the application protocol data from the server message. Working with a copy of the message, the program strips off the communications protocol(s) from the message and parses the remaining message to identify user-selectable options contained in the message such as commands, fields, etc. These items represent the set of allowable or authorized user actions for the particular “stage” of the current version of the application as set forth in the message. The set of allowable user actions is then stored by the extraction program in a protocol database accessible to a gateway or filter module.

Method and system for extracting application protocol characteristics

A method and system are disclosed for discriminating automatic computerized action from a human performed action. The invention is based on applying human advantage in applying sensory and cognitive skills to solving simple problems that prove to be extremely hard for computer software. Such skills include, but are not limited to processing of sensory information such as identification of objects and letters within a noisy graphical environment, signals and speech within an auditory signal, patterns and objects within a video or animation sequence. Human skills also include higher level cognitive processing such as understanding natural language and logical assignments. The method for discriminating between humans and computerized actions can be used during authentication, to limit access by automated agents, and for confirmation of actions.
