A system is provided for detecting, analyzing and quarantining unwanted files in a network environment. A host agent residing on a computing device in the network environment detects a new file introduced to the computing device and sends the new file to a network service for analysis. The network service is accessible to computing devices in the network environment. An architecture for the network service may include: a request dispatcher configured to receive a candidate file for inspection from a given computing device in the network environment and distribute the candidate file to one or more of a plurality of detection engines, where the detection engines operate in parallel to analyze the candidate file and output a report regarding the candidate file; and a result aggregator configured to receive reports from each of the detection engines regarding the candidate file and aggregates the reports in accordance with an aggregation algorithm.

Network service for the detection, analysis and quarantine of malicious and unwanted files

A security system provides a defense from known and unknown viruses, worms, spyware, hackers, and social engineering attacks The system can implement centralized policies that allow an administrator to approve, block, quarantine, or log file activities The system stores meta-information for files relating to security and at defined times after a file or a file hash is first received, performs security related analyses from a central server Analysis results are stored on the server, and the server can automatically change file meta-information Changes in file meta-information are provided to hosts

Centralized timed analysis in a network security system

A security system provides a defense from known and unknown viruses, worms, spyware, hackers, and unwanted or unknown software. The system can implement centralized policies that allow an administrator to approve, block, quarantine, or log file activities. The system maintains file meta-information in the hosts and in the server. A host detects file operations which can cause changes to file content or file name, and updates the host and/or server meta-information as a result. Changes in server meta-information are made available to hosts.

Content tracking in a network security system

Systems, methods, and program product to perform a cyber security risk assessment on a plurality of process control networks and systems comprising a plurality of primary network assets at an industrial process facility, are provided. An example of a system and program product can include an industrial and process control systems scanning module configured to identify networks and systems topology and to execute system and network security, vulnerability, virus, link congestion, node congestion analysis to thereby detect susceptibility to know threats to define potential vulnerabilities; a threats to vulnerabilities likelihood and consequences data repository module configured to determine a likelihood of each of a plurality of known threats exploiting identified vulnerabilities and to identify consequences of the exploitation to individual impacted systems and to overall plant operation; and a risk level evaluator module configured to determine a risk level rating for any identified vulnerabilities and provide recommended corrective actions.

Systems, Program Product and Methods For Performing a Risk Assessment Workflow Process For Plant Networks and Systems

A system, method and computer program product are provided for displaying a status of a security application. A status of at least one security application is initially identified. An index is calculated that is representative of a degree of risk associated with the status of the at least one security application. The index is then displayed.

System, method, and computer program product for conveying a status of a plurality of security applications

The invention provides an antivirus network or Internet appliance and methods therefor. A preferred embodiment of the Internet appliance according to the invention comprises an interface connecting the Internet appliance to a terminal, a memory, and a network connection connecting the Internet appliance to a network (such as a wide area network (WAN) or the Internet) wherein data in the network are operable with a corresponding network protocol (such as TCP/IP). Protocol-level programs are stored in the memory for receiving data being transmitted from the network to the terminal through the Internet appliance wherein the protocol-level programs are compatibly operable with the network protocol. Application-level antivirus programs are stored in the memory for detecting computer viruses in the received data serving as a firewall against the detected computer viruses for the terminal. The Internet appliance according to this particular embodiment of the invention further includes a processor (such as a central processor unit or CPU) and an operating system for implementing the protocol-level programs and the antivirus programs, wherein the antivirus programs are advantageously transparent to the terminal.
