CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY 
       [0001]    The present application claims priority to Indian Patent Application No. 3245/MUM/2013, filed on Oct. 15, 2013, the entirety of which is hereby incorporated by reference. 
       TECHNICAL FIELD 
       [0002]    The present disclosure in general relates to a field of compliance services. More particularly, the present invention relates to a system and method to provide automated compliance audit services for Information Technology (IT) enabled organizations dealing in one or more IT related services. 
       BACKGROUND 
       [0003]    With the automation and strategic involvement of Information Technology (IT) in day to day operations, demand for IT compliance has increased marginally. While delivering services to clients, an organization is bound to meet several technical and legal obligations associated with the IT compliance. There are several compliance rules and regulations that need to be met by an organization. These rules and regulations may be imposed by government bodies and may also include requirements with respect to a customer&#39;s need and demand. These compliance rules and regulation are not only important and necessary, but they also affect overall operations of the organization. In order to comply with these compliance rules and regulations, organizations set their own internal policies in line with the rules and regulations set by the government. 
         [0004]    Organizations have to enforce these compliances rules and regulations with stringent processes and at appropriate frequency generate compliance reports and evidences to justify its compliant business process and operations. 
         [0005]    Also, the IT components that are people dependent are also under the compliance umbrella. Further, all the IT enabled sectors and organizations are bound to meet the standard compliance at each stages of a service life cycle such as Design, Build, Migrate, Operate, Improve, and Govern. Further, in order to meet the applicable standards, IT organizations need to individually analyze each and every compliance requirement. These requirements may vary from organization to organization based on the elements and profiles of the organization. As a result each compliance rule needs to be individually analysed and accordingly modelled to check the compliance of the IT organizations. The architecture of existing compliance auditors  102  is disclosed in  FIG. 1 . The organizations may provide different services to different IT organizations for instance organization A, organization B, organization C and organization D. As represented in  FIG. 1 , the compliance auditor  102  is bound to provide customized services X, Y, and Z to organization A, B, and C respectively since the each of these organizations is linked with a different set of IT systems. Further, the services may vary with the variation in a business vertical  104  and business process implementation  106 . 
         [0006]    Hence, several challenges are faced by the current solutions due to diverse compliance requirements, frequent updates and complex interpretations. Also, there is lack of systematic approach to check correctness and completeness of compliance checking process.

     DETAILED DESCRIPTION 
       [0019]    The present subject matter discloses an effective and efficient compliance auditing system and method for determining whether a target system is compliant with the applicable rules and regulation. The compliance auditing system also determines whether the target system is compliant to a set of internal policies associated with the target system. To determine the compliance of the target system, initially, the rules and regulations set by a government are identified in the form of clauses by analysing compliance documents that store the compliance rules and regulations in text format. The clauses define a set of attributes that need to be checked in the target system. The clauses in the compliance documents also define the industrial standards that need to be mapped against the attributes to determine whether the target system is compliant as per the set industrial standards. 
         [0020]    In one example, the identified clauses are parsed by the compliance auditing system in order to extract the attributes present in each clause. In the next step the attributes are stored in a standard template referred as control. The control is user as a basic unit of checking the compliance of the target system. Further, the target system is analysed to determine elements present in the target system. In the next step, the controls that are applicable to the elements of the target system are identified. 
         [0021]    Subsequently, the profile of each element in the target system is identified by the compliance auditing system. The profile information is used to calibrate the controls to suit the environment of the target system. These calibrated controls are then compared with the configuration of the target system to determine whether the target system is compliant with the rules and regulation of the target system. The controls may be reused for multiple target systems by fine-tuning the controls based on the profiles associated with different elements at different target systems. 
         [0022]    While aspects of described system and method for determining compliance of a target system, the described system and method may be implemented in any number of different computing systems, environments, and/or configurations, the embodiments are described in the context of the following exemplary system. 
         [0023]    Referring now to  FIG. 2 , a network implementation  200  of a Compliance auditing system  202  to determine compliance of the target system  208  to the set of rules and regulations is illustrated, in accordance with an embodiment of the present subject matter. In one embodiment, the Compliance auditing system  202  enables extracting clauses from compliance documents, wherein the clauses define the compliance rules and regulations. In one example, the identified clauses are parsed to extract attributes, these attributes are then stored in a control. The control is a standard template that stores attributes specified by the corresponding clause. 
         [0024]    Further, the target system  208  is analysed to determine elements present in the target system  208 . In the next step, the controls that are applicable to the elements of the target system  208  are also identified. Subsequently, the profile of each element in the target system  208  is identified. This profile information is used to calibrate the controls to suit the environment of the target system  208 . The controls are then compared with the configuration of the target system  208  to determine whether the target system  208  is compliant with the rules and regulation applicable to the target system  208 . 
         [0025]    Although the present subject matter is explained considering that the Compliance auditing system  202  is implemented on a server, it may be understood that the Compliance auditing system  202  may also be implemented in a variety of computing systems, such as a laptop computer, a desktop computer, a notebook, a workstation, a mainframe computer, a server, a network server, and the like. In one implementation, the Compliance auditing system  202  may be implemented in a cloud-based environment. It will be understood that the Compliance auditing system  202  may be accessed by multiple users through one or more user devices  204 - 1 ,  204 - 2  . . .  204 -N, collectively referred to as user devices  204  hereinafter, or applications residing on the user devices  204 . Examples of the user devices  204  may include, but are not limited to, a portable computer, a personal digital assistant, a handheld device, and a workstation. The user devices  104  are communicatively coupled to the Compliance auditing system  202  through a network  206 . Further the target system  208  may be connected to the compliance auditing system  202  through the network  206 . 
         [0026]    In one implementation, the network  206  may be a wireless network, a wired network or a combination thereof. The network  206  can be implemented as one of the different types of networks, such as intranet, local area network (LAN), wide area network (WAN), the internet, and the like. The network  206  may either be a dedicated network or a shared network. The shared network represents an association of the different types of networks that use a variety of protocols, for example, Hypertext Transfer Protocol (HTTP), Transmission Control Protocol/Internet Protocol (TCP/IP), Wireless Application Protocol (WAP), and the like, to communicate with one another. Further the network  106  may include a variety of network devices, including routers, bridges, servers, computing devices, storage devices, and the like. 
         [0027]    Referring now to  FIG. 3 , the Compliance auditing system  202  is illustrated in accordance with an embodiment of the present subject matter. In one embodiment, the Compliance auditing system  202  may include at least one processor  302 , an input/output (I/O) interface  304 , and a memory  306 . The at least one processor  302  may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, and/or any devices that manipulate signals based on operational instructions. Among other capabilities, the at least one processor  302  is configured to fetch and execute computer-readable instructions stored in the memory  306 . 
         [0028]    The I/O interface  304  may include a variety of software and hardware interfaces, for example, a web interface, a graphical user interface, and the like. The I/O interface  304  may allow the Compliance auditing system  202  to interact with a user directly or through the client devices  204 . Further, the I/O interface  304  may enable the Compliance auditing system  202  to communicate with other computing devices, such as web servers and external data servers (not shown). The I/O interface  304  can facilitate multiple communications within a wide variety of networks and protocol types, including wired networks, for example, LAN, cable, etc., and wireless networks, such as WLAN, cellular, or satellite. The I/O interface  304  may include one or more ports for connecting a number of devices to one another or to another server. 
         [0029]    The memory  306  may include any computer-readable medium known in the art including, for example, volatile memory, such as static random access memory (SRAM) and dynamic random access memory (DRAM), and/or non-volatile memory, such as read only memory (ROM), erasable programmable ROM, flash memories, hard disks, optical disks, and magnetic tapes. The memory  306  may include modules  308  and data  310 . 
         [0030]    The modules  308  include routines, programs, objects, components, data structures, etc., which perform particular tasks, functions or implement particular abstract data types. In one implementation, the modules  308  may include a document analysis module  312 , a target system analysis module  314 , a control execution module  316 , and other modules  318 . The other modules  318  may include programs or coded instructions that supplement applications and functions of the compliance auditing system  202 . 
         [0031]    The data  310 , amongst other things, serves as a repository for storing data processed, received, and generated by one or more of the modules  308 . The data  310  may also include compliance documents  322 , a system database  324 , a control repository  326 , and other data  328 . The other data  328  may include data generated as a result of the execution of one or more modules in the other module  318 . 
         [0032]    In one implementation, at first, a user may use the client device  204  to access the Compliance auditing system  202  via the I/O interface  304 . The users may register themselves using the I/O interface  304  in order to use the Compliance auditing system  202 . The working of the Compliance auditing system  202  may be explained in detail in  FIGS. 4 to 7  explained below. The Compliance auditing system  202  may be used for dynamically determining compliance level of the target system  208 . In order to determine compliance level of the target system  208 , the Compliance auditing system  202 , at first, determines the rules and regulations applicable to the IT organization by analysing a plurality of compliance documents  322 . The compliance document may summarize well known compliance rules and regulations such as the Sarbanes-Oxley Act (SOX), the Health Insurance Portability and Accountability Act (HIPAA), BASEL III, and Payment Card Industry Data Security Standard (PCI-DSS) set by the government. The compliance documents  322  may also include internal policies set by the target system  208  as well as a plurality of other IT organizations for which the target system  208  provides different service. In one of the present implementation, the compliance documents  322  are analysed by a document analysis module  312 . 
         [0033]    Referring now to  FIG. 4 , a method  400  for determining compliance level of the target system  208  is shown, in accordance with an embodiment of the present subject matter. The method  400  may be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, functions, etc., that perform particular functions or implement particular abstract data types. The method  400  may also be practiced in a distributed computing environment where functions are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, computer executable instructions may be located in both local and remote computer storage media, including memory storage devices. 
         [0034]    The order in which the method  400  is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method  400  or alternate methods. Additionally, individual blocks may be deleted from the method  400  without departing from the spirit and scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof. However, for ease of explanation, in the embodiments described below, the method  400  may be considered to be implemented in the above described compliance auditing system  202 . 
         [0035]    At block  402 , the compliance document  322  may be parsed to determine clauses present in the compliance document  322 . In one embodiment, the compliance documents  322  including PCI-DSS, HIPPA, and SOX as well as internal policies associate with the target system  208 . 
         [0036]    At block  404 , a plurality of attributes associated with the clauses are identified, these attributes may include a compulsory pattern, a optional pattern, a citation, a control pre-requisite, a risk level, a control type and the profile applicability. 
         [0037]    At block  406 , first set controls are generated from the clauses based upon the plurality of attributes that are associated with the clauses  402 . In one embodiment, the first set of controls may be stored in Excel or XML document format. 
         [0038]    In one embodiment, the document analysis module  312  may perform the steps of blocks  402 ,  404  and  406 . The working of the document analysis module  312  is further explained in  FIG. 5 . 
         [0039]    At block  408 , the target system  208  is remotely analysed to identify the elements associated with the target system  208 . Based on the elements, a second set of controls are identified from the first set of controls. The second set of controls is a collection of controls that are applicable to elements associated with the target system  208   
         [0040]    At block  410 , the second set of controls is calibrated based on profiles associated with the element and a set of industrial standards applicable to the profiles associated with the elements. 
         [0041]    In one embodiment, the target system analysis module  314  may be configured to perform the steps of blocks  408  and  410 . The working of the target system analysis module  314  is further explained in  FIG. 6 . 
         [0042]    At block  412 , the configuration files of the target system  208  is compared with the second set of controls so calibrated to determine the compliance of each element of the target system  208 . In one embodiment, the compliance determination module  316  may be configured to perform the steps of block  412 . The working of the compliance determination module  316  is further explained in  FIG. 7 . 
       Document Analysis Module 
       [0043]    Referring to  FIG. 5 , a flowchart representing detailed working of the document analysis module  312  along with the working of other components of the compliance auditing system  202  for converting the clauses into first set of controls is illustrated, in accordance with an embodiment of the present subject matter. 
         [0044]    At step  502 , in one implementation, in order to extract clauses from the compliance documents  322 , the document analysis module  312  may, at first, perform natural language processing on the compliance documents  322  and extract all the clauses present in the compliance documents  322 . In one embodiment, the clauses may be classified as a simple clause, a complex clause, a citation specific clause, and a composite clause. A simple clause may define only a compulsory pattern to be checked to identify the compliance of the target system  208 . Further, the complex clause may define the compulsory pattern as well as an optional pattern to identify the compliance of the target system  208 . Further, the citation specific clause may define a specified pattern to be checked in specific citation for determining compliance of the target system  208 . Further the composite clause may define pre-requisites to be checked in the citation in order to determine compliance of the target system  208 . 
         [0045]    At step  504 , once the clauses are identified, a parsing technique is used by the document analysis module  312  to identify attributes and associated conditions present in each clause. The attributes define a set of conditions that need to be followed in order to comply with the rules and regulation present in the compliance documents  322 . In one embodiment the attributes may include a compulsory pattern, an optional pattern, a citation, a control pre-requisite, a risk level, a control type, and the profile applicability. 
         [0046]    At step  506 , for each clause, a control is generated by the document analysis module  312 . The control is a standard template storing all the attributes associated with the corresponding clause. All the controls associated with the clauses are then stored in the control repository  326  in the form of a first set of controls. The first set of controls represents all the clauses that are present in the compliance documents  322 . 
         [0047]    However, all the first set of controls may not be applicable to the target system  208  whose compliance level is to be determined. The target system analysis module  314  determines controls form the first set of controls, applicable to the target system  208 . These applicable control are identified by the target system analysis module  314  based on the elements that are present in the target system  208 . 
       Target System Analysis Module 
       [0048]      FIG. 6  illustrates a flowchart representing detailed working of the target system analysis module  314  along with the working of other components of the compliance auditing system  202  for identifying controls from the first set of controls that are applicable to the target system  208  based on the elements associated with the target system  208 . The controls that are applicable to the target system  208  are hereafter referred to as second set of controls. 
         [0049]    At step  602 , in order to identify the second set of controls, the target system analysis module  314  identifies the elements that are associated with the target system  208 . The elements that are associated with the target system  208  may include a network layer, an applications layer, an operating system, a database, and middleware. Additionally the elements may also include a data centre, a cloud environment, applications, communication protocols, load balancers, virtual machines, a storage space, firewalls, a Network Attached Storage (NAS), a Storage Attached Networks (SAN), a server, and network devices. In one embodiment, based on the requirement of the compliance coverage to be provided, a single element associated with the target system  208  may be identified for compliance level checking. 
         [0050]    At step  604 , the target system analysis module  314  traverses through each control from the first set controls and determines whether the control is applicable to at least one element of the target system  208 . All the controls that are identified as applicable to the elements of the target system  208  are stored in the control repository as second set of controls. 
         [0051]    At step  606 , profiles associated with elements are also identified from the target system analysis module  314 . The profiles associated with the elements may include security, element management, monitor and logs, version and path management, as well as authentication and authorization. The identified profiles are used to calibrate the second set of controls, before testing the target system  208  for determining compliance level of the target system  208 . 
         [0052]    The process of checking the compliance level of the target system  208  using the second set of controls so calibrated is performed by the compliance determination module  316 . The working of the compliance determination module is explained with respect to  FIG. 7 . 
       Compliance Determination Module 
       [0053]      FIG. 7 , illustrates a flowchart representing detailed working of the compliance determination module  316  along with the working of other components of the compliance auditing system  202  for checking the compliance level of the target system  208  using the second set of controls so calibrated. 
         [0054]    At step  702 , in one embodiment, the compliance determination module  316  extracts configuration files from the target system  208 . The configurations files store critical information of all the elements present in the target system  208 . 
         [0055]    At step  704 , the compliance determination module  316  compares the configuration files with the second set of controls so calibrated to identify whether the configuration of each element in the configuration file is as per the configuration specified by the corresponding control from the second set of controls. In one embodiment, a control from the second set of controls may be checked for a particular citation in the configuration file of the target system  208 , the control may specify a citation start and a citation end in between which the control needs to be checked. The citation start and the citation end define a boundary for checking a compulsory pattern based upon the configuration of the target system  208 . 
         [0056]    In one embodiment, the results of the comparison are then processed by a compliance report generator. The compliance report generator generates detailed compliance reports summarizing the details of the elements that are compliant and non-compliant to the rules and regulations specified by the compliance documents  322 . 
       Working Example 
       [0057]    One of the clause in the compliance document states that “At the network layer the LAN manager authentication level must be set to: 
         [0058]    1. Send NTLMv2 response only if the server is acting as operating system server 
         [0059]    2. Send NTLMv2 response only and refuse LM &amp; NTLM if the server is acting as a Domain Controller. 
         [0060]    3. Other than send LM &amp; NTLM responses use NTLMv2 session security if negotiated, if the server is acting as a web server.” 
         [0061]    The clause is converted into a control A 
         [0062]    “1. [if (server profile==operating system server), (the LAN manager authentication level==Send NTLMv2 response only] or 
         [0063]    2. [if (server profile==Domain Controller), (the LAN manager authentication level==Send NTLMv2 response only refuse LM &amp; NTLM] or 
         [0064]    3. [if (server profile==web server), (the LAN manager authentication level==Other than Send LM &amp; NTLM responses use NTLMv2 session security]” by the compliance auditing system. 
         [0065]    Initially the compliance auditing system identifies a server as the elements associated with the target system. In the next step, the profile of the server is identified as member server. Based on the profile of the server, the compliance auditing system calibrates the control A as “If (the LAN manager authentication level==Other than Send LM &amp; NTLM responses use NTLMv2 session security) pass, else fail” 
         [0066]    The Exemplary embodiments discussed above may provide certain advantages. Though not required to practice aspects of the disclosure, these advantages may include those provided by the following features. 
         [0067]    Some embodiments enable a system and a method to provide a systematic approach to check correctness and completeness of compliance checking process for the target system.
