This invention relates to cryptographic communications methods and systems that protect a server from a connection depletion attack. Specifically, the invention presents a method for allocating a resource comprising the steps of receiving a resource allocation request from a client, imposing a computational task and a time limit for correct completion of the task upon the client, verifying that the task was performed correctly within the time limit, and allocating the resource if the task was correctly performed within the time limit.

A computer system analysis tool and method that will allow for qualitative and quantitative assessment of security attributes and vulnerabilities in systems including computer networks. The invention is based on generation of attack graphs wherein each node represents a possible attack state and each edge represents a change in state caused by a single action taken by an attacker or unwitting assistant. Edges are weighted using metrics such as attacker effort, likelihood of attack success, or time to succeed. Generation of an attack graph is accomplished by matching information about attack requirements (specified in “attack templates”) to information about computer system configuration (contained in a configuration file that can be updated to reflect system changes occurring during the course of an attack) and assumed attacker capabilities (reflected in “attacker profiles”). High risk attack paths, which correspond to those considered suited to application of attack countermeasures given limited resources for applying countermeasures, are identified by finding “epsilon optimal paths.”

Systems and methods are provided for protecting a defense with a self defending intrusion system. Data packets may be monitored to detect a pattern of activity indicating a potential attack.

A method and apparatus for verifying the integrity of devices on a target network. The apparatus has security subsystems and a master security system hierarchically connected to the security subsystems via a secure link. The target network includes various intrusion detection devices, which may be part of the security subsystem. Each intrusion detection device generates a plurality of event messages when an attack on the network is detected. The security subsystem collects these event messages, correlates, and analyzes them, and performs network scanning processes. If certain events warrant additional scrutiny, they are uploaded to the master security system for review.

Conventional methods of addressing a Distributed Denial of Service attack include taking the target node offline, and routing all traffic to an alternate countermeasure, or “sinkhole” router, therefore requiring substantial lag time to reconfigure the target router into the network. In a network, a system operator monitors a network for undesirable message traffic. Upon a notification of such undesirable message traffic, traffic is rerouted to a filter complex to separate undesirable traffic. The filter complex establishes an alternate route using a second communications protocol, and uses the alternate route to redirect the desirable message traffic to the target node. The use of the second protocol avoids conflict between the redirected desirable traffic and the original, or first, protocol which now performs the reroute. In this manner, the filter complex employs a second alternate communications protocol to reroute and redirect desirable message traffic to the target node while diverting undesirable message traffic, and therefore avoids widespread routing configuration changes by limiting the propagation breadth of the second protocol.

Various embodiments of the invention provide solutions (including inter alia, systems, methods and software) for dealing with online fraud. In particular, various embodiments of the invention provide advanced responses to an identified instance of online fraud. Such advanced responses can incorporate one or more of a variety of strategies for defeating an attempt by a server to filter and / or otherwise avoid responses to its fraudulent activity. Merely by way of example, in accordance with some embodiments, one or more HTTP responses to a server's request (such as an online form, etc.) may be submitted and / or transmitted for reception by the server. In some cases, each of the submitted responses may appear to comprise valid information responsive to the server's request. In other cases, one or more countermeasures may be implemented to defeat an attempt by a phisher (or any other operator of an illegitimate server) to filter responses.

An architecture is provided for a widely distributed security system (SDI-SCAM) that protects computers at individual client locations, but which constantly pools and analyzes information gathered from machines across a network in order to quickly detect patterns consistent with intrusion or attack, singular or coordinated. When a novel method of attack has been detected, the system distributes warnings and potential countermeasures to each individual machine on the network. Such a warning may potentially include a probability distribution of the likelihood of an intrusion or attack as well as the relative probabilistic likelihood that such potential intrusion possesses certain characteristics or typologies or even strategic objectives in order to best recommend and / or distribute to each machine the most befitting countermeasure(s) given all presently known particular data and associated predicted probabilistic information regarding the prospective intrusion or attack. If any systems are adversely affected, methods for repairing the damage are shared and redistributed throughout the network.

A method of detecting an intrusion into (or an anomaly in a behavior of) a target software system begins by instrumenting the target software system to generate behavior data representing a current observation or observation aggregate. The method then determines whether the current observation or observation aggregate warrants a second level examination; preferably, this determination is made by processing the current observation or observation aggregate through a first level detection algorithm that provides a first, provisional indication of a possible intrusion. If a result of executing the first level detection algorithm indicates that the current observation or observation aggregate warrants a second level examination, the method continues by processing the current observation or observation aggregate through at least one or more second level detection algorithms to provide a second, more definite, fine grain indication of a possible intrusion. The observation aggregates used by the first and second level detection algorithms may be the same or different. The first and second level detection algorithms may be executed in the same or different systems, machines or processors. The target software system operation may be suspended as the current observation or observation aggregate is processed through the one or more second level detection algorithms. A given action (e.g., sending an alert, logging the event, activating a countermeasure, or the like) may be taken if the result of the second level examination indicates a possible intrusion. Multiple algorithms may be executed together within a single examination level, with the individual results then analyzed to obtain a composite result or output indicative of intrusive or anomalous behavior.

A communication system and a security assurance device are proposed, which are capable of assuring that a target party for communication is implementing security countermeasures. A server 3 transmits information 104 necessary for AC issuance to a security assurance authority 2. The security assurance authority 2 verifies the security of the server 3 during communication based upon this information necessary for AC issuance 104. And, when the security of the server 3 during communication is confirmed, the security assurance authority 2 issues an AC 105 which proves the security of the server 3 during communication, and transmits it to the server 3. Upon receipt of this AC 105, the server 3 transmits the AC 105 to a client 4, according to a connection request from the client 4. And, upon receipt of this AC 105, the client 4 verifies the security during communication of the server 3, based upon the AC 105.
