 Insufficient Service Level Agreement (SLA) would be the most probable cause for an organization to lack the ability to properly establish performance indicators for its Web hosting solution during an audit. A Web hosting solution is a service that provides the infrastructure, resources, and tools for hosting and maintaining a website or a web application on the internet. A Web hosting solution can offer various benefits, such as:

• Improving the availability and accessibility of the website or web application by ensuring that it is online and reachable at all times
• Enhancing the performance and scalability of the website or web application by optimizing the speed, load, and capacity of the web server
• Increasing the security and reliability of the website or web application by providing the backup, recovery, and protection of the web data and content
• Reducing the cost and complexity of the website or web application by outsourcing the web hosting and management to a third-party provider

A Service Level Agreement (SLA) is a contract or an agreement that defines the expectations, responsibilities, and obligations of the parties involved in a service, such as the service provider and the service consumer. An SLA can include various components, such as:

• Service description: a detailed explanation of the scope, purpose, and features of the service
• Service level objectives: a set of measurable and quantifiable goals or targets for the service quality, performance, and availability
• Service level indicators: a set of metrics or parameters that are used to monitor and evaluate the service level objectives
• Service level reporting: a process that involves collecting, analyzing, and communicating the service level indicators and objectives
• Service level penalties: a set of consequences or actions that are applied when the service level objectives are not met or violated

Insufficient SLA would be the most probable cause for an organization to lack the ability to properly establish performance indicators for its Web hosting solution during an audit, because it could mean that the SLA does not include or specify the appropriate service level indicators or objectives for the Web hosting solution, or that the SLA does not provide or enforce the adequate service level reporting or penalties for the Web hosting solution. This could affect the ability of the organization to measure and assess the Web hosting solution quality, performance, and availability, and to identify and address any issues or risks in the Web hosting solution.

The other options are not the most probable causes for an organization to lack the ability to properly establish performance indicators for its Web hosting solution during an audit, but rather the factors that could affect or improve the Web hosting solution in other ways. Absence of a Business Intelligence (BI) solution is a factor that could affect the ability of the organization to analyze and utilize the data and information from the Web hosting solution, such as the web traffic, behavior, or conversion. A BI solution is a system that involves the collection, integration, processing, and presentation of the data and information from various sources, such as the Web hosting solution, to support the decision making and planning of the organization. However, absence of a BI solution is not the most probable cause for an organization to lack the ability to properly establish performance indicators for its Web hosting solution during an audit, because it does not affect the definition or specification of the performance indicators for the Web hosting solution, but rather the analysis or usage of the performance indicators for the Web hosting solution. Inadequate cost modeling is a factor that could affect the ability of the organization to estimate and optimize the cost and value of the Web hosting solution, such as the web hosting fees, maintenance costs, or return on investment. A cost model is a tool or a method that helps the organization to calculate and compare the cost and value of the Web hosting solution, and to identify and implement the best or most efficient Web hosting solution. However, inadequate cost modeling is not the most probable cause for an organization to lack the ability to properly establish performance indicators for its Web hosting solution during an audit, because it does not affect the definition or specification of the performance indicators for the Web hosting solution, but rather the estimation or optimization of the cost and value of the Web hosting solution. Improper deployment of the Service-Oriented Architecture (SOA) is a factor that could affect the ability of the organization to design and develop the Web hosting solution, such as the web services, components, or interfaces. A SOA is a software architecture that involves the modularization, standardization, and integration of the software components or services that provide the functionality or logic of the Web hosting solution. A SOA can offer various benefits, such as:

• Improving the flexibility and scalability of the Web hosting solution by allowing the addition, modification, or removal of the software components or services without affecting the whole Web hosting solution
• Enhancing the interoperability and compatibility of the Web hosting solution by enabling the communication and interaction of the software components or services across different platforms and technologies
• Increasing the reusability and maintainability of the Web hosting solution by reducing the duplication and complexity of the software components or services

However, improper deployment of the SOA is not the most probable cause for an organization to lack the ability to properly establish performance indicators for its Web hosting solution during an audit, because it does not affect the definition or specification of the performance indicators for the Web hosting solution, but rather the design or development of the Web hosting solution.

Minimization of the need for decision making during a crisis is the main benefit that a Business Continuity Plan/Disaster Recovery Plan (BCP/DRP) will provide. A BCP/DRP is a set of policies, procedures, and resources that enable an organization to continue or resume its critical functions and operations in the event of a disruption or disaster. A BCP/DRP can provide several benefits, such as:

• Improving the resilience and preparedness of the organization and its staff in handling a disruption or disaster
• Enhancing the performance and efficiency of the organization and its systems in recovering from a disruption or disaster
• Increasing the compliance and alignment of the organization and its plans with the internal or external requirements and standards
• Facilitating the monitoring and improvement of the organization and its plans by identifying and addressing any gaps, issues, or risks

Minimization of the need for decision making during a crisis is the main benefit that a BCP/DRP will provide, because it can ensure that the organization and its staff have a clear and consistent guidance and direction on how to respond and act during a disruption or disaster, and avoid any confusion, uncertainty, or inconsistency that might worsen the situation or impact. A BCP/DRP can also help to reduce the stress and pressure on the organization and its staff during a crisis, and increase their confidence and competence in executing the plans.

The other options are not the benefits that a BCP/DRP will provide, but rather unrealistic or incorrect expectations or outcomes of a BCP/DRP. Guaranteed recovery of all business functions is not a benefit that a BCP/DRP will provide, because it is not possible or feasible to recover all business functions after a disruption or disaster, especially if the disruption or disaster is severe or prolonged. A BCP/DRP can only prioritize and recover the most critical or essential business functions, and may have to suspend or terminate the less critical or non-essential business functions. Insurance against litigation following a disaster is not a benefit that a BCP/DRP will provide, because it is not a guarantee or protection that the organization will not face any legal or regulatory consequences or liabilities after a disruption or disaster, especially if the disruption or disaster is caused by the organization’s negligence or misconduct. A BCP/DRP can only help to mitigate or reduce the legal or regulatory risks, and may have to comply with or report to the relevant authorities or parties. Protection from loss of organization resources is not a benefit that a BCP/DRP will provide, because it is not a prevention or avoidance of any damage or destruction of the organization’s assets or resources during a disruption or disaster, especially if the disruption or disaster is physical or natural. A BCP/DRP can only help to restore or replace the lost or damaged assets or resources, and may have to incur some costs or losses.

Monitoring of a control should occur at a rate concurrent with the volatility of the security control when implementing Information Security Continuous Monitoring (ISCM) solutions. ISCM is a process that involves maintaining the ongoing awareness of the security status, events, and activities of a system or network, by collecting, analyzing, and reporting the security data and information, using various methods and tools. ISCM can provide several benefits, such as:

• Improving the security and risk management of the system or network by identifying and addressing the security weaknesses and gaps
• Enhancing the security and decision making of the system or network by providing the evidence and information for the security analysis, evaluation, and reporting
• Increasing the security and improvement of the system or network by providing the feedback and input for the security response, remediation, and optimization
• Facilitating the compliance and alignment of the system or network with the internal or external requirements and standards

A security control is a measure or mechanism that is implemented to protect the system or network from the security threats or risks, by preventing, detecting, or correcting the security incidents or impacts. A security control can have various types, such as administrative, technical, or physical, and various attributes, such as preventive, detective, or corrective. A security control can also have different levels of volatility, which is the degree or frequency of change or variation of the security control, due to various factors, such as the security requirements, the threat landscape, or the system or network environment.

Monitoring of a control should occur at a rate concurrent with the volatility of the security control when implementing ISCM solutions, because it can ensure that the ISCM solutions can capture and reflect the current and accurate state and performance of the security control, and can identify and report any issues or risks that might affect the security control. Monitoring of a control at a rate concurrent with the volatility of the security control can also help to optimize the ISCM resources and efforts, by allocating them according to the priority and urgency of the security control.

The other options are not the correct frequencies for monitoring of a control when implementing ISCM solutions, but rather incorrect or unrealistic frequencies that might cause problems or inefficiencies for the ISCM solutions. Continuously without exception for all security controls is an incorrect frequency for monitoring of a control when implementing ISCM solutions, because it is not feasible or necessary to monitor all security controls at the same and constant rate, regardless of their volatility or importance. Continuously monitoring all security controls without exception might cause the ISCM solutions to consume excessive or wasteful resources and efforts, and might overwhelm or overload the ISCM solutions with too much or irrelevant data and information. Before and after each change of the control is an incorrect frequency for monitoring of a control when implementing ISCM solutions, because it is not sufficient or timely to monitor the security control only when there is a change of the security control, and not during the normal operation of the security control. Monitoring the security control only before and after each change might cause the ISCM solutions to miss or ignore the security status, events, and activities that occur between the changes of the security control, and might delay or hinder the ISCM solutions from detecting and responding to the security issues or incidents that affect the security control. Only during system implementation and decommissioning is an incorrect frequency for monitoring of a control when implementing ISCM solutions, because it is not appropriate or effective to monitor the security control only during the initial or final stages of the system or network lifecycle, and not during the operational or maintenance stages of the system or network lifecycle. Monitoring the security control only during system implementation and decommissioning might cause the ISCM solutions to neglect or overlook the security status, events, and activities that occur during the regular or ongoing operation of the system or network, and might prevent or limit the ISCM solutions from improving and optimizing the security control.

In a change-controlled environment, the activity that is most likely to lead to unauthorized changes to production programs is promoting programs to production without approval. A change-controlled environment is an environment that follows a specific process or a procedure for managing and tracking the changes to the hardware and software components of a system or a network, such as the configuration, the functionality, or the security of the system or the network. A change-controlled environment can provide some benefits for security, such as enhancing the performance and the functionality of the system or the network, preventing or mitigating some types of attacks or vulnerabilities, and supporting the audit and the compliance activities. A change-controlled environment can involve various steps and roles, such as:

• Change request, which is the initiation or the proposal of a change to the system or the network, by a user, a developer, a manager, or another stakeholder. A change request should include the details and the justification of the change, such as the scope, the purpose, the impact, the cost, or the risk of the change.
• Change review, which is the evaluation or the assessment of the change request, by a group of experts or advisors, such as the change manager, the change review board, or the change advisory board. A change review should include the decision and the feedback of the change request, such as the approval, the rejection, the modification, or the postponement of the change request.
• Change development, which is the implementation or the execution of the change request, by a group of developers or programmers, who are responsible for creating or modifying the code or the program of the system or the network, according to the specifications and the requirements of the change request.
• Change testing, which is the verification or the validation of the change request, by a group of testers or analysts, who are responsible for checking or confirming the functionality and the quality of the code or the program of the system or the network, according to the standards and the criteria of the change request.
• Change deployment, which is the installation or the integration of the change request, by a group of administrators or operators, who are responsible for moving or transferring the code or the program of the system or the network, from the development or the testing environment to the production or the operational environment, according to the schedule and the plan of the change request.

Promoting programs to production without approval is the activity that is most likely to lead to unauthorized changes to production programs, as it violates the change-controlled environment process and procedure, and it introduces potential risks or issues to the system or the network. Promoting programs to production without approval means that the code or the program of the system or the network is moved or transferred from the development or the testing environment to the production or the operational environment, without obtaining the necessary or the sufficient authorization or consent from the relevant or the responsible parties, such as the change manager, the change review board, or the change advisory board. Promoting programs to production without approval can lead to unauthorized changes to production programs, as it can result in the following consequences:

• The code or the program of the system or the network may not be fully or properly tested or verified, and it may contain errors, bugs, or vulnerabilities that may affect the functionality or the quality of the system or the network, or that may compromise the security or the integrity of the system or the network.
• The code or the program of the system or the network may not be compatible or interoperable with the existing or the expected components or features of the system or the network, and it may cause conflicts, disruptions, or failures to the system or the network, or to the users or the customers of the system or the network.
• The code or the program of the system or the network may not be documented or recorded, and it may not be traceable or accountable, and it may not be aligned or compliant with the policies or the standards of the system or the network, or of the organization or the industry.
