     DETAILED DESCRIPTION 
     Security Operation Centers (SOCs) and security teams in general typically have task systems in place to manage tickets; however, it is often a very manual process when sorting through a list of offenses and assigning a task to be handled by an analyst of a computer security operation center. The workflow comes in the form of a long list and requires a user to manually sort through the list of tasks associated with a computer security offense to determine which task needs to be dealt with and determine which category that task falls under. Embodiments of the present invention addresses this problem by automatically assigning tasks to a specific analyst based on a cognitive approach, given a characteristic of the offense or task, and analyst specific data. A security to-do board may be created specifically for security teams that not only manage tasks/tickets from issue to close but also pull in offenses from the offense list provided by a Security Information and Event Management system (SIEM) or other security product to a universal board for a security team to refer to and which assigns the tasks to a particular analyst that is optimally suited for dealing with that specific offense type. 
     Thus, there is a need for a task assignment system for automatically assigning a task to an analysis based on a cognitive approach to the particular offense and analyst-specific data. Embodiments of the present invention may perform/use sentimental analysis and personality insights of an analyst, in addition to parsing computer security offense data, to automatically assign a task associated with the computer security offense to an optimum or ideal analyst that is available.

     Referring still to  FIG. 1 , embodiments of the task assignment system  100  may include an analyst profile system  111 . Embodiments of the analyst profile system  111  may be communicatively coupled to the computing system  120  over computer network  107 . Embodiments of the analyst profile system of the task assignment system  100  depicted in  FIG. 1  may system include a plurality of analyst profiles of analysts of the computer security operation center. For instance, each analyst of the computer security operation center may be profiled, wherein the analyst profile data may be stored or otherwise contained in an analyst profile database  112  coupled to the analyst profile system  111 . Embodiments of the analyst profile system  111  may be one or more websites, applications, databases, storage devices, repositories, servers, computers, engines, and the like, that may service, run, store or otherwise contain information and/or data regarding analysts. The analyst profile system  111  may be accessed or may share a communication link over network  107 . In an exemplary embodiment, an analyst profile of the analyst profile system  111  may include data regarding an expertise of the analyst, a title of the analyst, an experience level of the analyst, an interest of the analyst, a skill level of the analyst, a success history of the analyst, and the like. The analyst-specific data may be collected by or provided to the analyst profile system  111  based on a plurality sources. A first source may be a training data or evaluation data from a manger about the experience, experience, title, interests, preferences, skills, and the like. These criteria may be entered into the analyst profile database  112  using the analyst profile system  111  by the manager. A second source may be the analyst entering data using a software application on the analyst computing device interfacing with the analyst profile system  111 . A third source may be results of sentiment, intent, and/or personality analysis of analyst shared content across various platforms, such as a social media, social network platforms, work collaboration platforms, computer security software applications, etc. A fourth source may be data received from one or more input devices  110  associated with the analyst. The analyst-specific data may be continuously collected and updated in the analyst profile system  111 , with data from the plurality of sources. 
     Furthermore, embodiments of the computing system  120  may be equipped with a memory device  142  which may store various data/information/code, and a processor  141  for implementing the tasks associated with the task assignment system  100 . In some embodiments, a task assignment application  130  may be loaded in the memory device  142  of the computing system  120 . The computing system  120  may further include an operating system, which can be a computer program for controlling an operation of the computing system  120 , wherein applications loaded onto the computing system  120  may run on top of the operating system to provide various functions. Furthermore, embodiments of computing system  120  may include the task assignment application  130 . Embodiments of the task assignment application  130  may be an interface, an application, a program, an engine, a module, or a combination of modules. In an exemplary embodiment, the task assignment application  130  may be a software application running on one or more back end servers, servicing a SOC system. 
     The task assignment application  130  of the computing system  120  may include an offense module  131 , a selection module  132 , a confidence module  133 , and a task module  134 . A “module” may refer to a hardware-based module, software-based module or a module may be a combination of hardware and software. Embodiments of hardware-based modules may include self-contained components such as chipsets, specialized circuitry and one or more memory devices, while a software-based module may be part of a program code or linked to the program code containing specific programmed instructions, which may be loaded in the memory device of the computing system  120 . A module (whether hardware, software, or a combination thereof) may be designed to implement or execute one or more particular functions or routines. 
     Embodiments of the offense module  131  may include one or more components of hardware and/or software program code for receiving, detecting, acquiring, creating, and/or establishing a computer security offence. The computer security offense may be received from an offense list provided by a SIEM or other security product or software. For instance, embodiments of the offense module  131  may receive an alert or notification of a computer security offense that may attention from the SOC. In an exemplary embodiment, the offense module  131  may receive and/or process the computer security offense to create/generate a ticket or task, for analysis by the task assignment application  130 . Furthermore, embodiments of the offense module  131  may include one or more components of hardware and/or software program code for analyzing the computer security offense to determine a plurality of computer security offense characteristics. Embodiments of the computer security offense characteristics may include an offense type, a complexity of the computer security offense, an estimated time to closing the computer security offense, a technical field of the computer security offense, an urgency of the computer security offense, a severity level of the computer security offense, and the like. For instance embodiments of the offense module  132  may, in response to receiving the computer security offense, analyze the computer security offense to determine the characteristics and other data points from the content of the computer security offense and ticket associated therewith. The content of the computer security offense and/or ticket may be analyzed by a text analysis system that may parse, identify, scan, detect, analyze etc. words using, for example, a natural language processing technique, natural language classification, pre-trained language model, etc. to analyze the content of the computer security offense. The content of the computer security offense may include a source of the offense, a cause of the offense, a nature of the offense, a type of offense, list of components involved, a recency of the issue, a frequency of reported problems, a type of account, a number of times the offense has occurred in the past, a time of day, a day of a week, an amount of downtime, and account specific information, and the like. 
     Embodiments of the offense module  131  may parse the content to determine keywords that may be helpful in identifying and understanding the plurality of computer security offense characteristics, as well as to break down various categories of the computer security offense. In an exemplary embodiment, the keywords may be weighted in accordance with a priority set by, for example, a customer. A weighting scheme may be applied to one or more keywords which can affect the selection of an analyst, described in greater detail infra. The weighting scheme may be a numerical value used as a modifier to increase an importance of one or more aspect or characteristic of the computer security offense. For example, a customer may place a higher priority on immediate remediation of offenses relating to a DDoS attack, which means that if a keyword associated with DDoS is detected, then the task assignment application  130  may prioritize a schedule availability of an analyst over the analyst&#39;s interests in remediating DDoS attacks, as there may be more than one analyst who has an interest in remediating DDoS attacks. The weighting scheme may be helpful in distinguishing between multiple, ideal candidates to receive a task associated with remediating the offense. In another example, a customer may prefer that only analysts with over 10 years of experience dealing with enterprise management software issues handle offenses pertaining to the customer&#39;s enterprise servers. In this example, the task assignment application  130  may prioritize an experience level and a field of expertise of an analyst, as opposed to an analyst that may be immediately available and has an interest in enterprise server maintenance, but only 2 years of experience. 
     Furthermore, embodiments of the offense module  131  may access or otherwise query an offense database  113 , in response to the parsing the computer security offense. Embodiments of the offense database  113  may be one or more databases, storage devices, repositories, and the like, that may store or otherwise contain information and/or data regarding past tasks, issues, offenses, audio recordings and/or text of the audio calls from support/service calls, and the like. The offense database  113  may also be accessed over network  107 , and may be affiliated with, managed, and/or controlled by one or more third parties, such as SOCs of a company. The offense module  131  may access the offense database  113  using the keywords to obtain information from other offenses which may be similar, to calculate and/or confirm from previous completed offense an estimated time to completion, a complexity level of the offense, a technical field of the offense, a historical success rate with issues associated with the offense, various tasks that should be generated to remediate the offense, and other computer security offense characteristics. 
     Accordingly, embodiments of the offense module  131  may analyze the computer security offense to determine one or more characteristics of the computer security offense on a detailed level so that an appropriate analyst may be matched with the offense, using the task assignment application  130 . 
     With continued reference to  FIG. 1 , embodiments of the computing system  120  may include a calculating module  132 . Embodiments of the calculating module  132  may include one or more components of hardware and/or software program code for calculating a match score for a plurality of analyst profiles of an analyst profile system  111 . Embodiments of the match score may be a numerical value (e.g. 0-100) that may indicate a strength of a correlation between an analyst profile and the plurality of computer security offense characteristics. For instance, embodiments of the calculating module  132  may access or otherwise utilize the analyst profile system  111  in view of the characteristics of the computer security offense and weighted keywords, to locate an analyst that has a highest match score among a plurality of analysts with the computer security offense characteristics. Embodiments of the calculating module  132  may scan, parse, review, analyze, etc. a plurality of analyst profiles of the analyst profile system  111  to calculate or otherwise determine a match score or relevancy score for each or less then each analyst profile of the analyst profile system  111 . 
     Turning now to  FIG. 2 , which depicts an analyst profile  200  of the analyst profile system  111 , in accordance with embodiments of the present invention. Embodiments of the calculating module  132  may scan, parse, review, analyze, etc., a content  230  of the analyst profile  200 , and may first determine whether the content  230  is relevant to the computer security offense characteristics, and then calculate a match score based on a correlation between the offense characteristics and the analyst-specific data. Embodiments of an analyst profile  200  of an analyst  201  may contain content  230  and a name or identity  201  of the analyst and contact information. Here, the content  230  on the analyst profile provide various analyst-specific data, such as expertise, experience, interests, skill level, title, and availability. As an example, if the task assignment application  130  determines that the characteristics of a received offense relate to a DDoS attack, and the customer prioritizes a high skill level/success rate, the selection module  132  may calculate a high match score (e.g. numerical value, 0-100) for the analyst  201 . The information/content  230  of the analyst profile  200  indicates that the analyst  201  has a very high skill level which satisfies a priority of the customer, and also indicates that the analyst  201  has expertise in DDoS responses and has an interest in the topic, which means that the analyst-specific data is not only relevant to the offense, but deserving of a high match score (e.g. 92/100). If another analyst profile within the analyst profile system  111  indicates a similar interest but a lower skill level than analyst  201 , the calculating module  132  may attribute a lower match score to that analyst. Similarly, if another analyst profile within the analyst profile system  111  indicates a similar skill level but the analyst is not interested in or does not prefer to handle DDoS attacks, then the calculating module  132  may attribute a lower match score to that analyst. 
     Accordingly, calculating the match score for the analyst profiles, the task assignment application  130  may intelligently distinguish between analysts that may both be competent and capable of handling the task, but effectively selecting the analyst that is more ideal for a particular task, automatically and without manually sorting tasks. Further, the task assignment application  130  enables a workload to be spread across SOCs more evenly to ensure offenses are not all assigned to a single analyst with a heavy workload. 
     Moreover, as noted above, the analyst-specific data may also include an availability of the analyst in the analyst profile  200 . The availability of the analyst may affect the calculation of the match score. For example, embodiments of the offense module  131  may determine how long various offenses/issues take to resolve, using machine learning over time, data from the offense database  113  on previously completed tasks for similar issues, predictive models, and the like. The calculating module  132  may assess a schedule of the analyst either provided in the analyst profile  200  or by interfacing directly with an input device  110  associated with the analyst (e.g. accessing a calendar on the analyst&#39;s smart phone), to determine whether the analyst would have time to complete the task. For example, the analyst profile  200  may indicate that the analyst is currently free and available for the next 2 hours, but the calculating module  132  may determine that the task is expected to take 3 hours. In this case, the calculating module  132  may calculate a lower match score for the user because the analyst may be interrupted with other commitments, and adversely affect the analyst&#39;s ability to close the task, especially in a high priority/urgent scenario. 
     Referring back to  FIG. 1 , embodiments of the computing system  120  may include a selection module  133 . Embodiments of the selection module  133  may include one or more components of hardware and/or software program code for selecting an analyst profile with a highest match score of the plurality of analyst profiles. For instance, embodiments of the selection module  133  may evaluate the match scores calculated for the plurality of the analyst profiles of the analyst profile system  111 , and select the analyst profile with the highest match score. Moreover, embodiments of the selection module  133  may include one or more components of hardware and/or software program code for verifying that the highest match score exceeds a match score threshold. Embodiments of the match score threshold may be a minimum match score that must be exceeded prior to assigning the task to an analysis. The minimum match score may vary depending on a confidence level required for making a selection based on the analyst-specific data. If the match score threshold is exceeded by the highest match score of the selected analyst profile, then the selection module  133  may complete the selection. If the match score threshold is not met or exceeded, then the selection module  133  may not complete a selection, and may display the computer security offense/task as an open task, available to claim by any analyst that is a part of the SOC. 
     Furthermore, embodiments of the selection module  133  may assess a condition of the analyst using input device(s)  110 , such as one or more sensors, prior to the assigning of the task. Embodiments of the condition of the analyst may include a stress level, a tiredness level of the analyst, a rate of activity of the analyst, a frustration level of the analyst, an alertness level of the analyst, and the like. Embodiments of the one or more sensors used to assess a condition of the user may be positioned within an environment shared by the analyst, worn by the analyst, used by the analyst, or otherwise disposed in a location that can result in obtaining analyst data. Input device  110  may be a sensor, an input device, or any input mechanism. For example, input device  110  may be a biometric sensor, a wearable sensor, an environmental sensor, a camera, a camcorder, a microphone, a peripheral device, a computing device, a mobile computing device, such as a smartphone or tablet, facial recognition sensor, voice capture device, and the like. Embodiments of input devices  110  may also include a heart rate monitor used to track a current or historical average heart rate of the analyst; wireless-enabled wearable technology, such as an activity tracker or smartwatch that tracks a heart rate, an activity level (e.g. number of calories burned, total steps in a day, etc.), a quality of sleep, a diet, a number of calories burned; a robotic therapeutic sensor; a blood pressure monitor; a perspiration sensor; and other wearable sensor hardware. Embodiments of input devices  110  may further include environmental sensors either worn or placed in an analyst environment, such as an office or study, that can measure air quality, temperature, pressure, NO 2  levels, humidity, and the like, which may be helpful in gauging a condition of an analyst. 
     Further embodiments of input devices  110  may include one or more input devices or input mechanisms, including one or more cameras positioned proximate the analyst or within an environment shared by the analyst. The one or more cameras may capture image data or video data of an analyst, including a posture, facial expressions, perspiration, muscle activity, gestures, etc. Embodiments of the input devices  110  may also include one or more microphones positioned nearby the analyst to collect audio relating to the analyst, a keystroke logger that may measure a rate of typing, and other hardware input devices, such as an audio conversion device, digital camera or camcorder, voice recognition devices, graphics tablet, a webcam, VR equipment, mouse, touchpad, stylus, and the like, which may help gauge a work intensity or work output of an analyst. Further embodiments of sensors  110  may include a mobile computing device, such as a smartphone or tablet device, which may run various applications that contain data about the analyst. For example, an analyst&#39;s smartphone may include a sleep tracking application that may send sleep data to the computing system  120 , or may send relevant social media information to the computing system  120 . The mobile computing device as used as sensor may also utilize the device&#39;s camera, microphone, and other embedded sensors to send information to the computing system  120 . Moreover, embodiments of input device  110  may encompass other input mechanisms, such as a user computer that may send information to the computing system  120 , wherein the analyst computer may be loaded with software programs that are designed to track a productivity or work output level. 
     Additionally, embodiments of the input devices  110  may be in communication with each other. The input devices  110  may interact with each other for collecting comprehensive, accurate, timely, and organized data, and sending to computing system  120 . A first sensor of the one or more sensors may request help from another sensor of the one or more sensors to confirm a condition of the analyst or a data result from the first sensor. For example, a facial recognition sensor may communicatively interact with a perspiration sensor to confirm whether the analyst is indeed sweating, and may additionally communicate with a thermal sensor to determine whether the analyst is possibly sweating based on a temperature of the analyst&#39;s environment. The interactive communication between the sensors may modify, update, augment, bolster, confirm, reference, etc. data received and/or collected by the sensor, as well as improve the accuracy and efficiency of the data. 
     The condition of the analyst may assessed after selection of the analyst, prior to assigning the task to the user as a last step check before proceeding with the automatic assignment of the task, especially when the task is marked with a high severity level or a high priority score. If the analyst&#39;s condition is acceptable, for example, not detrimental to performance, then the task may be assigned to the analyst. If the condition of the analyst may result in unacceptable, for example, may act as a detriment to the analyst&#39;s performance, the selection module  133  may remove the selected analyst profile, and select the analyst profile with the next highest match score. In further embodiments, the condition data obtained by the input devices  110  may be fed to the analyst profile system  111  so that the task application  130  of computing system  120  may use the condition of the analyst as a factor in calculating the match score. 
     Referring back to  FIG. 1 , embodiments of the computing system  120  may also include a task module  134 . Embodiments of the task module  134  may include one or more components of hardware and/or software program code for assigning the task associated with the computer security offense to an analyst associated with the selected analyst profile. For instance, embodiments of the task module  134  may automatically assign the task to the analyst associated with the selected analyst profile. Embodiments of the task module  134  may notify the analyst using various electronic communication methods, and may also update a task management software used by the SOC so that all analysts, managers, etc. can view the schedules/tasks. 
     Various tasks and specific functions of the modules of the computing system  120  may be performed by additional modules, or may be combined into other module(s) to reduce the number of modules. Further, embodiments of the computer or computer system  120  may comprise specialized, non-generic hardware and circuitry (i.e., specialized discrete non-generic analog, digital, and logic-based circuitry) (independently or in combination) particularized for executing only methods of the present invention. The specialized discrete non-generic analog, digital, and logic-based circuitry may include proprietary specially designed components (e.g., a specialized integrated circuit, such as for example an Application Specific Integrated Circuit (ASIC), designed for only implementing methods of the present invention). Moreover, embodiments of the task assignment system  100  offers a method to automatically assign tasks using a cognitive approach to determine ideal matches for completing the task. The task assignment system  100  may be individualized to each analyst/analyst profile, by analyzing the analyst-specific data. 
     Referring now to  FIG. 3 , which depicts a flow chart of a method  300  for automatically assigning a task to an analyst of a computer security operation center, in accordance with embodiments of the present invention. One embodiment of a method  300  or algorithm that may be implemented for automatically assigning a task to an analyst of a computer security operation center with the task assignment system  100  described in  FIGS. 1-2  using one or more computer systems as defined generically in  FIG. 5  below, and more specifically by the specific embodiments of  FIG. 1 . 
     Embodiments of the method  300  for automatically assigning a task to an analyst of a computer security operation center, in accordance with embodiments of the present invention, may begin at step  301  wherein a computer security offense is received. Step  302  analyzes the computer security offense to determine characteristics of the offense. Step  303  calculates a match score of a match between the analyst profile and the offense characteristics. Step  304  selects the analyst associated with the analyst profile having the highest match score. Step  305  verifies that the match score of the selected analyst profile exceeds a minimum match score threshold. Step  306  assigns the task to the analyst. 
       FIG. 4  depicts a detailed flow chart of a method  400  for automatically assigning a task to an analyst of a computer security operation center, in accordance with embodiments of the present invention. Embodiments of the method  400  for automatically assigning a task to an analyst of a computer security operation center may begin at step  401 , wherein a computer security is offense is detected/received. Step  402  parses the computer offense to determine keywords and categorize the offense into a plurality of characteristics. Step  403  analyzes the analyst profile system  111  using keywords/weighted keywords. Step  404  calculates a match score. Step  405  selects the analyst profile or analyst with the highest match score. Step  406  determines whether the match score exceeds a minimum match score threshold. If not, then step  407  clears the selection and does not automatically assign the task, such that the task becomes freely available for pick-up by any analyst of the SOC. If yes, then step  408  determines whether a condition of the analyst is acceptable. If no, then step  408  returns to step  405  for selecting a new analyst or new analyst profile having the next highest match score. If yes, then step  409  assigns the task associated with the offense to the analyst with the highest match score and an acceptable condition.

     It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed. 
     Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models. 
     Characteristics are as follows: 
     On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service&#39;s provider. 
     Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs). 
     Resource pooling: the provider&#39;s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). 
     Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time. 
     Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service. 
     Service Models are as follows: 
     Software as a Service (SaaS): the capability provided to the consumer is to use the provider&#39;s applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings. 
     Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations. 
     Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls). 
     Deployment Models are as follows: 
     Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises. 
     Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises. 
     Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services. 
     Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds). 
     A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes. 
     Referring now to  FIG. 6 , illustrative cloud computing environment  50  is depicted. As shown, cloud computing environment  50  includes one or more cloud computing nodes  10  with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone  54 A, desktop computer  54 B, laptop computer  54 C, and/or automobile computer system  54 N may communicate. Nodes  10  may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment  50  to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices  54 A,  54 B,  54 C and  54 N shown in  FIG. 10  are intended to be illustrative only and that computing nodes  10  and cloud computing environment  50  can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).
