Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1-10 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Neumann (US Pat. 9,654,485 B1).
Neumann discloses the following subject matter:
1. A computer-implemented method for detection of a malicious activity by analyzing object behavior in a non-isolated environment, the method being executable by a processor communicatively coupled to a plurality of hosts of the non-isolated environment (Figs. 1 & 2), the method comprising:
receiving, by the processor, from a given host of the plurality of hosts, an event flow including data representative of events occurred at the given host (col. 8, line 65-col. 9, line19- The term “event log” (e.g., a log file) generally refers to data with respect to dynamic (e.g., run-time) behaviors that are gathered by one or more computer nodes 112, e.g., end points, intermediate nodes or other network devices coupled with network 114 in the computing environment 110. The data of event logs may be collected using one or more collection agents deployed by the system 100 and installed in the computer nodes 112. The agents are designated by the letter-“A” in the figures. In some embodiments, the event logs may store data collected by collection agent functionality embedded within or constituting applications running within the computer nodes 112. The event logs may contain data generated by anti-virus applications on the computer nodes 112. The event logs may contain alerts and related data generated by intrusion protection systems, intrusion detection systems and/or malware detection systems running in the computing environment 110. Each such system is encompassed by the terms “computer node” and “network device”. Each of the event logs contains data from (and, often, about) at least one of the computer nodes 112 in the computing environment 110, such as run-time activities, network activity, or other behavior.);
analyzing, by the processor, a given event sequence of the event flow having been generated for a predetermined period (col. 22, lines 49-53- the security monitoring framework 104 may be provided with an event log cache 130 (FIG. 1) to store event log data for a period of time or up to a quantity (data storage size) for later use in analysis), to generate, for a given event of the given event sequence, a respective internal event, the respective internal event being format-invariant to other events in the event flow (col. 24, lines 52-61- In step 506, the security monitoring framework 104 detects behavioral characteristics from the received event logs. In one embodiment, the security monitoring framework 104 detects the behavioral characteristics using independently deployable modules that are each configured for detecting a separate behavioral characteristic. For example, one module may be configured for detecting a spidering event, a second module may be configured to detect a hopping event, while a third module may be configured to detect an account probing event.);
applying, by the processor, to the respective internal event, a plurality of signature-based rules to determine at least one internal state marker of the given host associated with the given event sequence, respective internal state markers associated with the each one of the given event sequence being indicative of whether the given event sequence is associated with the malicious activity or not (col. 15, lines 21-57-A behavioral characteristic correlation module 218 correlates multiple behavioral characteristics 116 with one another using at least one of multiple correlation profiles 122 stored in the data source 106. The behavioral characteristic correlation module 218 may use one or more functions, such as a higher order function, a heuristic function, a schedule, a profile, and/or a probability distribution function, either singularly or in combination to determine correlations among multiple behavioral characteristics. Each correlation profile 120 generally includes information associated with a set of behavioral characteristics that form a behavior pattern. When associated behavioral characteristics in the normalized data are observed (e.g., detected) with a relatively high degree of relevance to each other as indicated by the behavioral characteristic pattern, they may provide evidence of an attack or at least a portion of an attack. The behavioral pattern of each correlation profile 120 may include any combination of behavioral characteristics that may be related to one another, such as those behavioral characteristics that occur during or close to the same time frame, behavioral characteristics that originate from the same computing node, behavioral characteristics that originate from multiple computing nodes that are owned by the same user or accessed using the same user credentials, behavioral characteristics that access or manipulate the same element of data, and the like.
An attack identification module 219 receives the determined behavioral fragments from the behavioral fragment detection module 218 and correlates those fragments with a plurality of attack patterns of known attacks previously detected and analyzed, as stored in the attack profiles repository 122. The attack identification module 219 may use, depending on the embodiment, one or more functions, such as a higher order function, a heuristic function, a schedule, a profile, blacklists, whitelists, and/or a probability distribution function, either singularly or in combination in identifying and verifying an attack.; col. 25, lines 8-12);
feeding, by the processor, the respective internal state markers to a trained machine-learning algorithm (MLA) to determine a prediction outcome thereof of whether the given event sequence is associated with the malicious activity, the trained MLA having been trained to determine whether the given event sequence is associated with the malicious activity based on the respective internal state markers of the given host associated therewith (col. 15, lines 21-57, col. 25, lines 8-12); and
in response to the prediction outcome exceeding a predetermined threshold value, determining, by the processor, the given event sequence having been occurred at the given host as being associated with the malicious activity (col. 16, lines 44-64-  In one embodiment, each behavioral characteristic may be associated with one or more weighting factors that represent a confidence level regarding the relevance of that characteristic to other detected behavioral characteristics within a behavioral fragment. That is, a behavioral characteristic having a relatively high weighting factor may have a relatively higher degree of relevance to others within a behavioral fragment as represented by the correlation profile, than another behavioral characteristic having a relatively lower weighting factor. Additionally, each behavioral characteristic may include multiple weighting factors that are associated with multiple aspects of one or more behavioral fragments. Moreover, each behavioral fragment may be associated with one or more weighting factors that may represent a confidence level regarding the relevance of that fragment to other detected behavioral fragment, in a manner just described for behavioral characteristics. An attack score may be generated based on weighting factors of the behavioral fragments and based on the attack profiles so as to indicate the likelihood that the detected behavioral fragments constitute attack fragments of an attack., col. 25, lines 22-28);
generating, by the processor, a report including the prediction outcome for presentation thereof to a user (col. 20, lines 12-26- An attack report generation module 228 may generate an alert or other report of an attack, and may include information regarding the behavioral characteristics and fragments associated with the attack, and, in some embodiments, the score(s) associated therewith. Moreover, a remedial action generation module 230 may be optionally deployed in some embodiments (and, for example, enabled by an administrator) to generate one or more remedial actions to mitigate the adverse effects of any identified attacks. For example, the security monitoring framework 104 may issue an alert message transmitted to administrators of the computing environment indicating that an attack has been identified, and the alert may be generated by the attack report generation module 228 or the remedial action generation module 230.).
2. The method of claim 1, prior to applying the plurality of signature-based rules, further comprising storing the respective internal event in a pipeline of internal events. (col. 25, lines 8-12- In step 508, the security monitoring framework 104 correlates the detected behavioral characteristics with a correlation profile 120 stored in the data source 106 to identify a set of related behavioral characteristics called behavioral fragments.)
3. The method of claim 1, wherein the determining the at least one internal state marker comprises detecting one of malicious activity and object in one of the given host of the plurality of hosts and a network thereof. (col. 17, lines 63-col. 18, line 8- the behavioral correlation module 218 receiving these two behavioral characteristics may correlate the unusual port activity and the unusual beaconing activity into a behavioral fragment based on their “relatedness” as indicated by a behavioral correlation profile. The behavioral correlation module 218, which may have sufficient evidence to associate the unusual port activity with a score of 0.80 (e.g., reflecting an assessment of a combination of its severity and confidence) and the unusual beaconing activity with a score of 0.75 (again, reflecting a combination of its severity and confidence), and an overall score (combining the component scores) of 0.40 confidence of a suspicious callback.)
4. The method of claim 3, wherein the at least one internal state marker is valid for a predetermined period. (col. 9, line 62 – col. 10, line 8- the criteria used to delineate what is considered normal behavioral characteristics as opposed to what is considered abnormal behavioral characteristics that may provide evidence or an indication of an attack. For example, multiple authentication attempts generated by the computing node 112 at a rate of less than a specified number of attempts per hour may be an indication of normal behavior, while any rate above that may be an indication of abnormal behavior. As another example, a spidering technique (e.g., blind searches or even mere communication for content on each of multiple computing nodes) during a first specified time of day (e.g., during business hours) may be considered normal behavior, while another spidering technique conducted during late night hours may be considered to be abnormal behavior.)
5. The method of claim 3, wherein the at least one internal state marker has been pre-assigned with a respective weight value. (col. 16, lines 44-60-  In one embodiment, each behavioral characteristic may be associated with one or more weighting factors that represent a confidence level regarding the relevance of that characteristic to other detected behavioral characteristics within a behavioral fragment. That is, a behavioral characteristic having a relatively high weighting factor may have a relatively higher degree of relevance to others within a behavioral fragment as represented by the correlation profile, than another behavioral characteristic having a relatively lower weighting factor. Additionally, each behavioral characteristic may include multiple weighting factors that are associated with multiple aspects of one or more behavioral fragments. Moreover, each behavioral fragment may be associated with one or more weighting factors that may represent a confidence level regarding the relevance of that fragment to other detected behavioral fragment, in a manner just described for behavioral characteristics.)
6. The method of claim 1, wherein at least one internal state indicated by the at least one internal state marker comprises at least one of: a set of flags indicative of a current state of the given host, file paths, a registry, processes, signatures, mutexes, synchronization objects, and counters. (col. 9, lines 31-39- For example, a behavior may be a request to open a communication port in a network device. Examples of behavioral characteristics may include certain criteria, such as a callback (e.g., outbound communication or communication attempts, sometimes referred to as beaconing) initiated by a segment of code and directed to a potential target computing node, the quantity and/or type of authentication (e.g., user login) attempts, data transmission techniques, network searching techniques, and the like.; col. 17, lines 63-col. 18, line 8- the behavioral correlation module 218 receiving these two behavioral characteristics may correlate the unusual port activity and the unusual beaconing activity into a behavioral fragment based on their “relatedness” as indicated by a behavioral correlation profile. The behavioral correlation module 218, which may have sufficient evidence to associate the unusual port activity with a score of 0.80 (e.g., reflecting an assessment of a combination of its severity and confidence) and the unusual beaconing activity with a score of 0.75 (again, reflecting a combination of its severity and confidence), and an overall score (combining the component scores) of 0.40 confidence of a suspicious callback.)
7. The method of claim 6, wherein the at least one internal state is valid for a predetermined period. (col. 9, line 62 – col. 10, line 8- the criteria used to delineate what is considered normal behavioral characteristics as opposed to what is considered abnormal behavioral characteristics that may provide evidence or an indication of an attack. For example, multiple authentication attempts generated by the computing node 112 at a rate of less than a specified number of attempts per hour may be an indication of normal behavior, while any rate above that may be an indication of abnormal behavior. As another example, a spidering technique (e.g., blind searches or even mere communication for content on each of multiple computing nodes) during a first specified time of day (e.g., during business hours) may be considered normal behavior, while another spidering technique conducted during late night hours may be considered to be abnormal behavior.)
8. The method of claim 1, wherein the trained MLA comprises at least one of: a linear model, a classifier, and a neural network. (col. 15, lines 52-57, col. 18, lines 16-22)
9. The method of claim 1, wherein the report further comprises at least one of: signature markers, information of the given host, contents of environment variables of processes running during occurrences of the given event sequence, information about connected devices, a screenshot, a screen video at a moment of the determining the given event sequence as being associated with the malicious activity, a sequence of user actions executed prior to the given event sequence, an incident graph. (col. 20, lines 12-35-  An attack report generation module 228 may generate an alert or other report of an attack, and may include information regarding the behavioral characteristics and fragments associated with the attack, and, in some embodiments, the score(s) associated therewith. Moreover, a remedial action generation module 230 may be optionally deployed in some embodiments (and, for example, enabled by an administrator) to generate one or more remedial actions to mitigate the adverse effects of any identified attacks. For example, the security monitoring framework 104 may issue an alert message transmitted to administrators of the computing environment indicating that an attack has been identified, and the alert may be generated by the attack report generation module 228 or the remedial action generation module 230. As another example, the security monitoring framework 104 may trace the origin of any computing nodes associated with the attack and halt operation of those computing nodes and/or any connections formed with these computing nodes to other nodes in the computing environment until the attack has been resolved. Although only several example remedial actions have been described, it should be understood that the security monitoring framework 104 may perform any number and type of remedial actions according to the identified attack.)
Regarding claim 10, it is rejected as applied to claim 1 because a corresponding system would have been necessitated to carry forth the method steps of claim 1.  The applied prior art also discloses the corresponding architecture. (Figs. 1 and 2)
