摘要： A method of progressive response for invoking and suspending blocking measures that defend against network anomalies such as malicious network traffic so that false positives and false negatives are minimized. When an anomaly is detected, the detector notifies protective equipment such as a firewall or a router to invoke a blocking measure. The blocking measure is maintained for an initial duration, after which it is suspended while another test for the anomaly is made. If the anomaly is no longer evident, the method returns to the state of readiness. Otherwise, a loop is executed to re-apply the blocking measure for a specified duration, then suspend the blocking measure and test again for the anomaly. If the anomaly is detected, the blocking measure is re-applied, and its duration is adapted. If the anomaly is no longer detected, the method returns to the state of readiness.

摘要： A method of, system for, and product for managing a denial of service attack in a multiprocessor environment comprising. The first step is establishing normal traffic usage baselines in the multiprocessor environment. Once the baseline is established the next step is monitoring outgoing traffic to detect a high proportion of packets being sent to a specific destination address, and a high number of outbound packets compared to said baseline. Next is monitoring ports and protocols to detect a high proportion of packets sent to a specific port, and a consistent use of a protocol for all packets for that port. If there is such consistent use of a protocol for all packets for that port as to evidence a denial of service attack, blocking measures are started to mitigate the apparent denial of service attack.

摘要： 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.

摘要： 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 data flow control method and system within a data switch. The data switch includes a plurality of input sections each having an associated input buffer and each transmitting data to an output section. In response to a detection of congestion within the output section, data transmissions from the plurality of input sections to the output section are paused. Input buffer occupancies of each of the input sections are then determined. Thereafter, and in response to a backpressure relief signal, the restart of said data transmission from each of the input sections to the output section is delayed in inverse proportion to each of the determined input buffer occupancies.

摘要： System, method and computer program for authenticating a user of a client computer to a remote server computer. A client computer initially sends a userID but not a password of the user to the remote server computer. In response to the userID, the server computer determines a subsequent time window during which the server computer will consider for authentication submission of a combination of the userID and a password. The server computer notifies the client computer of the time window. After receipt of the notification from the server computer, during the time window, the client computer sends the userID and a corresponding password to the server computer. In response to receipt of the userID and the corresponding password from the client computer, the server computer determines if the combination of the userID and the corresponding password is valid. If the combination of the userID and the corresponding password is valid, the server computer notifies the client computer that the combination of the userID and the corresponding password is valid. In response, the client computer establishes a session with the server computer and accesses a resource requiring a valid combination of userID and password to access. The server computer ignores combinations of userIDs and passwords submitted before or after the time window.

摘要： A remote user, two-way authentication and password change protocol that also allows parties to optionally establish a session key which can be used to protect subsequent communication. In a preferred embodiment, a challenge token is generated and exchanged which is a one-time value that includes a random value that changes from session to session. The construction and use of the challenge token avoids transmission of the password or even the transmission of a digest of the password itself. Thus the challenge token does not reveal any information about a secret password or a digest of the password.

摘要： A method and system for controlling a plurality of pipes in a computer network, including at least one processor for a switch, the at least one processor having a queue, the plurality of pipes utilizing the queue for transmitting traffic through the switch, wherein each pipe is assigned a priority ranking class, each class has a unique priority rank with respect to each of the other classes, the ranks ranging from a highest priority rank to a lowest priority rank. A transmission probability is calculated for each pipe responsive to its priority rank. If excess bandwidth exists for the queue, the transmission probability of each pipe is linearly increased. Alternatively, if excess bandwidth does not exist, the transmission probability for each pipe is exponentially decreased. Packets are transferred from a pipe to the queue responsive to the pipe transmission probability and priority rank.
