System and method for recording temperature on an RFID tag. A first RFID tag is attached to a container. The first RFID tag includes a temperature sensor. The container contains a multiplicity of packages. A multiplicity of second RFID tags are attached to the multiplicity of packages, respectively. The first RFID tag transmits temperature information to the multiplicity of second RFID tags. In response, the multiplicity of second RFID tags record the temperature information. Consequently, there is no need for expensive temperature sensors on the multiplicity of RFID tags on the packages. According to features of the present invention, the first RFID tag is an active RFID tag, and the multiplicity of second RFID tags are passive RFID tags. The first RFID tag also transmits other information to the multiplicity of second RFID tags to enable the second RFID tags to authenticate the temperature information. Other types of environmental sensors such as a humidity sensor or vibration sensor can substitute for the temperature sensor.

A detection and response system including a set of algorithms for detecting within a stream of normal computer traffic a subset of (should focus on network traffic eliciting a response) TCP or UDP packets with one IP Source Address (SA) value, one or a few Destination Address (DA) values, and a number exceeding a threshold of distinct Destination Port (DP) values. A lookup mechanism such as a Direct Table and Patricia search tree record and trace sets of packets with one SA and one DA as well as the set of DP values observed for the given SA, DA combination. The detection and response system reports the existence of such a subset and the header values including SA, DA, and multiple DPs of the subset. The detection and response system also includes various administrative responses to reports.

A system, method and program product for blocking unwanted e-mails. An e-mail is identified as unwanted. A source IP address of the unwanted e-mail is determined. Other source IP addresses owned or registered by an owner or registrant of the source IP address of the unwanted e-mail are determined. Subsequent e-mails from the source IP address and the other IP addresses are blocked. This will thwart a spammer who shifts to a new source IP address when its spam is blocked from one source IP address.
摘要:
A communication network is operated by detecting an anomaly in the communication traffic at a plurality of nodes in a communication network. A first blocking measure A is independently applied at respective ones of the plurality of nodes to the anomalous traffic that stops the anomalous traffic. A second blocking measure B is independently determined at the respective ones of the plurality of nodes such that application of a logical combination of the first blocking measure A and the second blocking measure B to the anomalous traffic stops the anomalous traffic.
摘要:
A router includes a relatively low bandwidth communication connection to a small computer, a relatively high bandwidth communication connection to a communication network; and a processing unit for executing in the router a set of permit rules for permitting flow of communication packets with respect to the connections for user initiated sessions, the permit rules including a default rule for discarding all packets with respect to the small computer in traffic not pertaining to sessions initiated by the small computer.

A method, apparatus, and computer instructions for providing a current and complete security compliance view of an enterprise system. The present invention provides the ability to gain a real-time security posture and security compliance view of an enterprise and to assess the risk impact of known threats and attacks to continued business operations at various levels is provided. Responsive to a change to an enterprise environment, a request, or an external threat, an administrator loads or updates at least one of a Critical Application Operations database, a Historical database, an Access Control database, a Connectivity database, and a Threat database. Based on a comparison of information in the databases against similar security data elements from company or external policies, the administrator may generate a Security Compliance view of the enterprise. A Security Posture view may also be generated by comparing the Security Compliance view against data in the Threat database.
摘要:
A technique for tracking one or more thresholds relating to the blocking of a particular screen name used on an IM system is disclosed. If the number of people who have blocked a particular screen name reaches a threshold amount, a determination is made that the screen name is being used by a spimmer or other bothersome person, and disciplinary action can be taken. In a preferred embodiment, the email address associated with a user name of a suspected spimmer is identified and all screen names associated with that email address are also subjected to disciplinary action, if desired. Thus, an IM company can suspend all screen names of a spimmer that are tied to the same email address, even though not all (or even none) of the screen names individually have reached a threshold level for discipline/suspension.
摘要:
Communication traffic is processed by detecting an anomaly in the communication traffic. A first blocking measure A is applied to the anomalous traffic that stops the anomalous traffic. A second blocking measure is determined such that application of a logical combination of the first blocking measure A and the second blocking measure to the anomalous traffic stops the anomalous traffic.
摘要:
A detection and response system that generates an Alert if unauthorized scanning is detected on a computer network that includes a look-up table to record state value corresponding to the sequence in which SYN, SYN/ACK and RST packets are observed. A set of algorithms executed on a processing engine adjusts the state value in response to observing the packets. When the state value reaches a predetermined value indicating that all three packets have been seen, the algorithm generates an Alert.
摘要:
System and method for tracking inventory of a multiplicity of products. First RFID tags are associated with respective products or groups of products. Second Active RFID tags are associated with respective first containers for the multiplicity products. A third Active RFID tag is associated with a second container for the first containers. First RFID tags broadcast their respective identifications. Second Active RFID tags hash the identities of the first RFID tags within their respective first containers and broad their hashed values. Third Active RFID tag hash the hashed values broadcast by the second Active RFID tags. An expected value is compared to a result of the third Active RFID tag hashing the hashed values broadcast by the second Active RFID tags.
