A system, method and computer program product are provided for network-based scanning for potentially malicious content. Incoming and/or outgoing network communications traveling over a network are monitored, preferably at a gateway. Potentially malicious content in the network communications is identified. The identified potentially malicious content of the network communications is quarantined to help prevent damage that could be caused if the content is indeed malicious. In one embodiment, a pattern for testing the potentially malicious content network communications for malicious code can be executed. The network communications are conditionally delivered over the network based on the testing. In other embodiments, the network communications are delivered over the network after a predetermined delay and/or upon receiving a user request to release the suspect content from quarantine.

In an inspection facility (e.g. at a gateway server, at a proxy server, at a firewall to a network, at an entrance to a local area network or even at the user's computer) connected to an anti-virus center for updates, a method for protecting a computer from suspicious objects (e.g. a file, an executable, a Web page, an email message, etc.), the method comprising the steps of: inspecting an object; upon determining the object as suspicious, holding the object in quarantine (e.g. preventing from the object to be forwarded to its destination) for a time period, thereby enabling the inspection facility to be updated during the time period by the anti-virus center; upon ending of the time period, re-inspecting the object, thereby inspecting the object by updated inspection tests; and upon determining the object as malicious by the re-inspection, blocking the object, otherwise forwarding the object toward its destination.

A system and method for automatically altering device functionality based on the occurrence of certain predetermined conditions. A link may be established between a device and a trusted server to provide an association between various conditions that may be detected at the device and actions that are to be taken on the device. In particular, software traps can be set up and linked to device functionality such that execution of the trap may automatically disable or enable certain device capabilities. Some aspects of the invention are directed to a system and method for remotely setting software traps for detecting software viruses and, upon execution of the traps, several methods for establishing a quarantine on infected devices.

Detecting unsolicited messages (spam) by aggregating information across multiple recipients and/or across the same or differing messaging protocols. Multiple messages are analyzed to detect a call to action pattern that specifies a target communication address with which the recipients are requested to communicate, such as an email address, an Internet address, a telephone number, and the like. Once a frequency threshold of messages containing the call to action pattern is reached, subsequent messages are temporarily quarantined for evaluation by a human operator. If the human determines that the messages are not spam, the human can release the quarantined messages, and indicate that future messages with the call to action pattern are not to be delayed. Conversely, if the human determines that the messages are spam, the human can delete the messages in quarantine, and indicate that all future messages with that call to action pattern are to be deleted automatically.

A system and method for ensuring that machines having invalid or corrupt states are restricted from accessing network resources are provided. A quarantine server located on a trusted machine in a network provides a bill of health to a quarantine agent located on a client computer that wishes to gain access to network resources administered by an organization. The quarantine agent requests bill of health from the quarantine server, and receives a manifest of checks that the client computer must perform. The quarantine agent then sends a status report on the checks back to the quarantine server. If the client computer is in a valid security state, the bill of health is issued to the client. If the client computer is in an invalid state, the client is directed to install the appropriate software/patches to achieve a valid state. When a client requests the use of network resources from a network administrator, the network administrator requests the client's bill of health. If the bill of health is valid, the client is admitted to the network. If the bill of health is invalid, or if the client does not have a quarantine agent, the client is placed in quarantine, in which the only network resources accessible to the client are those necessary to install the quarantine agent and requisite software/patches to achieve a valid state.

A quarantine network system includes a quarantine control apparatus and a quarantine client connectable with each other. The quarantine control apparatus includes a receiving unit to receive verification information of the quarantine client, an identification unit to identify a security policy that the quarantine client is required to conform to, and an inspection request unit to transmit an inspection request to the quarantine client, requesting the quarantine client to inspect conformance/non-conformance to the identified security policy. The quarantine client includes a receiver to receive the inspection request from the quarantine control apparatus, a storage unit storable inspection information to inspect conformance/non-conformance to the security policy, a reading unit to read out the inspection information from the storage unit, an inspection unit to inspect the quarantine client using the read-out inspection information, and an inspection result reporting unit to transmit an inspection result to the quarantine control apparatus.

The present invention provides a system, method, and computer-readable medium for quarantining a file. Embodiments of the present invention are included in antivirus software that maintains a user interface. From the user interface, a user may issue a command to quarantine a file or the quarantine process may be initiated automatically by the antivirus software after malware is identified. When a file is marked for quarantine, aspects of the present invention encode file data with a function that is reversible. Then a set of metadata is identified that describes attributes of the file including any heightened security features that are used to limit access to the file. The metadata is moved to a quarantine folder, while the encoded file remains at the same location in the file system. As a result, the encoded file maintains the same file attributes as the original, non-quarantined file, including any heightened security features.

A system and method for ensuring that machines having invalid or corrupt states are restricted from accessing host resources are provided. A quarantine agent (QA) located on a client machine acquires statements of health from a plurality of quarantine policy clients. The QA packages the statements and provides the package to a quarantine enforcement client (QEC). The QEC sends the package to a quarantine Health Certificate Server (HCS) with a request for a health certificate. If the client provided valid statements of health, the HCS grants the client health certificate that may be used in IPsec session negotiation.

A method of remotely treating malicious mobile terminals connected to a mobile communications network. In one embodiment, when a malicious mobile terminal is detected by the intrusion-detection services of the network, the network changes the subscriber profile associated with the mobile terminal to operate the latter in a quarantine mode. The packet-switched subsystem of the network then links the quarantined mobile terminal to a remediation manager. The remediation manager remotely treats the mobile terminal, e.g., to repair or reinstall any corrupted software, terminate any active malicious processes, delete or quarantine any malware, and restore the operating system, configuration, and/or memory of the mobile terminal to a clean operational state. After the treatment, the network reverts the subscriber profile back to the initial state and removes the mobile terminal from the quarantine.

A system and method for ensuring that machines having invalid or corrupt states are restricted from accessing network resources are provided. A quarantine coordination client (QCC) located on a client machine acquires statements of health from a plurality of quarantine policy clients. The QCC packages the statements and provides the package to a quarantine enforcement client (QEC). The QEC sends the package to a quarantine enforcement server (QES) with a request for network access. The QES passes the package to a quarantine coordination server (QCS) that disassembles the package and passes the individual statements of health to corresponding quarantine policy servers (QPS). The QPSs validate the statements of health and inform the QCS of the result. If the client provided valid statements of health, the QES grants the client access to the network.

A proximity network map defines who and what objects have come in contact of each other including location and time. This map selects the list people who have come in contact with known infected people based on contagious disease epidemiology criteria to control its spread, or to prevent radiation poisoning, limit bio-chemicals exposure, etc. These people then undergo testing and quarantine procedures. It monitors hygiene practices and reduces nosocomial infections in hospitals and mitigates the pandemic flu threat by controlling contamination. It controls people interaction, information flow in a high security environment, control crime or gang activities. Each person or object carrying a proximity-sensing unit with unique ID records all units it encountered over a period of time. This information is stored with time stamp in a relational database and transferred to network servers. The databases are then replication throughout via a central web database server for retrieval and analysis.

Envelopes and other containers intended for mail transportation possess a biological agent/toxin indicator operative upon the interior in detection of volatile bases including gaseous amines released from bacterial biological agents including Bacillus antracis, i.e. anthrax. The biological agent indicator has an acidic acid-base indicator compound that irreversibly changes color when neutralized by volatile bases. The compound is applied in liquid form to an appropriately porous substrate. A polymeric matrix is specifically suggested for this substrate. Irreversible indication of the presence of volatile bases including amines produced by live bacterial agents as toxins at temperate ambient conditions down to below freezing is provided. An indicator compound having a pH of 2-5 is recommended. Halogenated xanthene, sulphonated azo, and sulphonated hydroxy-functional triphenylmethane dyes are suggested. The presence of toxins produced by live bacterial biological agents within a package or container upon which the indicator is mounted is indicated by a slowly reversible color change. Primary public use envelopes and collection containers, secondary transportation and stationary quarantine enclosures, and articles worn inside a room with mail and when handling mail including a badge and gloves are specifically suggested.

Autonomic threat detection is performed by collecting traffic samples of traffic patterns associated with a networked device having a device resident validation module. A threat analysis system is used to recognize a pattern of traffic indicative of a compromised device based at least in part upon the traffic samples. If the samples indicate a compromised device, the device is quarantined and a security check is performed on the device. The security check may include requesting data from the corresponding device resident validation module to determine if the device is compromised, analyzing data from the device resident validation module of the quarantined device and taking an action based upon analysis of the data. At least one of the data from the device resident validation module of the quarantined device or the traffic samples is utilized to autonomically train the threat analysis system to identify compromised devices.

The one or more health checks may be invoked pro-actively on a scheduled basis, reactively in response to a condition detected in the system, or may even be invoked manually by a user such as a system administrator.

“False positives” of valid E-mail messages are avoided according to a method which creates a numeric score that represents the probability that the message in question is valid, and then quarantines the message in an area separate from the intended message recipient user's primary in-box for scheduled notification to the user of the presence of possible valid messages for selection.

Messages are marked on the basis of whether they are originated in a home network or in a foreign network. Messages originated in the foreign network may be subjected to further filtering and may be put to ‘quarantine’ for further checking.

We present, in exemplary embodiments of the present invention, novel systems and methods for syndromic surveillance that can automatically monitor symptoms that may be associated with the early presentation of a syndrome (e.g., fever, coughing, sneezing, runny nose, sniffling, rashes). Although not so limited, the novel surveillance systems described herein can be placed in common areas occupied by a crowd of people, in accordance with local and national laws applicable to such surveillance. Common areas may include public areas (e.g., an airport, train station, sports arena) and private areas (e.g., a doctor's waiting room). The monitored symptoms may be transmitted to a responder (e.g., a person, an information system) outside of the surveillance system, such that the responder can take appropriate action to identifying, treat and quarantine potentially infected individuals, as necessary.

The invention relates to a method for rapid detection of a target nucleic acid amplification product while preventing cross-contamination between target nucleic acid amplification products and avoiding false positives, comprising the steps of: a) leaving the reaction tube unopened after the amplification reaction is finished, so as to prevent the target nucleic acid amplification product from leaking out and resulting in contamination; b) placing the unopened reaction tube inside an enclosed unit, making the target nucleic acid amplification product be transferred to a test strip from the reaction tube in a physically enclosed environment; c) performing detection in a visual read-out manner, and determining the result; d) discarding the enclosed unit in a safety place as a whole without opening it after the detection. The invention also relates to a totally enclosed unit for detecting a target nucleic acid amplification product, and still relates to applications of the totally enclosed rapid detection unit in detection of infectious pathogens, food industry, agriculture, livestock husbandry, customs quarantine control, and determination of DNA.
