Objective: Information Security Management aims to ensure the confidentiality, integrity and availability of an organization's information, data and IT services. ITIL V3 treats Information Security Management as part of the Service Design core volume, resulting in a better integration of this process into the Service Lifecycle (the previous ITIL version provided guidance on Security Management in a separate book). ITIL does not provide a detailed explanation of all aspects of Information Security Management, as there are dedicated and more detailed standards available (see, for example, ISO 27001). Following the introduction of Design Coordination in ITIL 2011 the information flows have been adapted.
Process Objective: To design appropriate technical and organizational measures in order to ensure the confidentiality, integrity, security and availability of an organization's assets, information, data and services.
Process Objective: To make sure that all security mechanisms are subject to regular testing. Process Objective: To detect and fight attacks and intrusions, and to minimize the damage incurred by security breaches. Process Objective: To review if security measures and procedures are still in line with risk perceptions from the business side, and to verify if those measures and procedures are regularly maintained and tested. A schedule for the regular testing of all availability, continuity and security mechanisms, jointly maintained by Availability, IT Service Continuity and Information Security Management. Rules and criteria used to determine if an Event is significant and to decide upon an appropriate response.
Note: The output "Event Filtering and Correlation Rules" has been added in ITIL 2011, to emphasize that (some) Event filtering and correlation rules should be designed by Information Security Management to support the detection of security issues. The Information Security Management Policy describes and communicates the organization's approach to managing information security.
The Information Security Report provides other Service Management processes and IT Management with information related to Information Security issues. A list of known security vulnerabilities compiled from input by third-party product suppliers.
A warning produced by Information Security Management, typically released when outbreaks of security threats are foreseeable or already under way.
A virtual repository of all Information Security Management data, usually stored in multiple physical locations.
Underpinning Information Security Policies are specific policies complementing the main Information Security Policy by setting binding rules for the use of systems and information as well as for the use and delivery of services, with the aim of improving information security. The Information Security Manager is responsible for ensuring the confidentiality, integrity and availability of an organization’s assets, information, data and IT services.

ITIL - the Information Technology Infrastructure Library - is a set of best practices and guidelines that define an integrated, process-based approach for managing information technology services.
This article will provide a general overview of ITIL and discuss how ITIL can improve how organizations implement and manage information security.
ITIL began in the 1980s as an attempt by the British government to develop an approach for efficient and cost-effective use of its many IT resources. When most people discuss ITIL, they refer to the ITIL Service Support and Service Delivery books. ITIL stresses service quality and focuses on how IT services can be efficiently and cost-effectively provided and supported. ITIL defines the objectives, activities, inputs, and outputs of many of the processes found in an IT organization.
The ITIL framework is typically implemented in stages, with additional processes added in a continuous service improvement program. Tactical: The strategy is translated into an appropriate organizational structure and specific plans that describe which processes have to be executed, what assets have to be deployed, and what the outcome(s) of the processes should be. A description of each of the numerous IT processes covered by ITIL is beyond the scope of this article. Configuration Management: Best practices for controlling production configurations (for example, standardization, status monitoring, asset identification). Incident Management: Best practices for resolving incidents (any event that causes an interruption to, or a reduction in, the quality of an IT service) and quickly restoring IT services. Problem Management: Best practices for identifying the underlying cause(s) of IT incidents in order to prevent future recurrences.
Change Management: Best practices for standardizing and authorizing the controlled implementation of IT changes.
Availability Management: Best practices for maintaining the availability of IT services guaranteed to a customer (for example, optimizing maintenance and design measures to minimize the number of incidents). Financial Management: Best practices for understanding and managing the cost of providing IT services (for example, budgeting, IT accounting, charging). Service Level Management: Best practices for ensuring that agreements between IT and IT customers are specified and fulfilled. There is also a Service Desk function that describes best practices for establishing and managing a central point of contact for users of IT services.


Figure 1 depicts the above processes, showing how the Service Desk function serves as the single point of contact for the various service management processes. More detailed information about the above processes and Service Desk function can be found in the references listed at the end of this article. ITIL seeks to ensure that effective information security measures are taken at strategic, tactical, and operational levels.
The IT department determines the feasibility of the requirements and compares them to the organization's minimum information security baseline. The customer and IT organization negotiate and define a service level agreement (SLA) that includes definition of the information security requirements in measurable terms and specifies how they will be verifiably achieved. Operational level agreements (OLAs), which provide detailed descriptions of how information security services will be provided, are negotiated and defined within the IT organization. Customers receive regular reports about the effectiveness and status of provided information security services.
There are a number of important ways that ITIL can improve how organizations implement and manage information security.
ITIL can enable organizations to develop and implement information security in a structured, clear way based on best practices.
With its requirement for continuous review, ITIL can help ensure that information security measures maintain their effectiveness as requirements, environments, and threats change. ITIL establishes documented processes and standards (such as SLAs and OLAs) that can be audited and monitored. ITIL enables information security staff to discuss information security in terms other groups can understand and appreciate. The organized ITIL framework prevents the rushed, disorganized implementation of information security measures. ITIL does not typically start with IT - it is usually initiated by senior management such as the CEO or CIO. Information security measures are steadily increasing in scope, complexity, and importance.

Harold Kerzner has written a tome that encompasses virtually all areas of Project Management (PM). IT Security Management has evolved into an essential element in the 21st century workplace.
These IT professionals have primary responsibilities that include the utilization of the CIA Triad principles to ensure information systems are secure. Over the past several years there have been standards organizations around the world worked together to create, modify, and maintain Information Technology Security standards. The critical need for IT Security professionals that can facilitate secure systems and data has resulted in many IT Security certifications.
The Information Security Management industry continues to evolve in a rapidly changing innovative world that requires constant reevaluation of systems and vulnerabilities resulting from new and emerging technology around the globe. Keeping up-to-date on emerging trends in the areas of standards is paramount to your success as an IT professional. ITIL Security Management usually forms part of an organizational approach to security management which has a wider scope than the IT Service Provider.
Rather, ITIL highlights the most important activities and assists in identifying interfaces with other Service Management processes. The process overview of ITIL Security Management (.JPG) is showing the most important interfaces (see Figure 1). It includes references to more specific Underpinning Information Security Policies which, for example, set binding rules for the use of systems and information.
The list contains instructions for preventive measures and for the handling of security breaches once they occur.
The aim is to make sure that users and IT staff are able to identify any attacks and take appropriate precautions. A Test Report is created for example during Release tests in the Service Transition stage or during tests carried out by Availability, IT Service Continuity or Information Security Management. He is usually involved in an organizational approach to Security Management which has a wider scope than the IT service provider, and includes handling of paper, building access, phone calls etc., for the entire organization. In addition to the often touted benefits of ITIL - aligning IT with the needs of the business, improving service quality, decreasing the costs of IT service delivery and support - the framework can aid the information security professional both directly (there is a specific Security Management process) and indirectly.
Using the experiences and expertise of successful IT professionals, a British government agency developed and released a series of best-practice books, each focusing on a different IT process. These contain a set of structured best practices and standard methodologies for core IT operational processes such as Change, Release, and Configuration Management, as well as Incident, Problem, Capacity, and Availability Management.


In the ITIL framework, the business units within an organization who commission and pay for IT services (e.g.
It primarily focuses on what processes are needed to ensure high quality IT services; however, ITIL does not provide specific, detailed descriptions about how the processes should be implemented, as they will be different in each organization. What follows are brief, general descriptions of the ITIL processes that, along with the Security Management process, have a significant relationship with information security. By identifying, controlling, maintaining and verifying the items that make up an organization's IT infrastructure, these practices ensure that there is a logical model of the infrastructure. These practices ensure that normal service is restored as quickly as possible after an incident occurs.
These practices ensure that changes are implemented with minimum adverse impact on IT services, and that they are traceable. These practices ensure that only tested and correct versions of authorized software and hardware are provided to IT customers. These practices ensure that IT services are provided efficiently, economically, and cost-effectively. These practices ensure that IT services are maintained and improved through a cycle of agreeing, monitoring, reporting, and reviewing IT services. Two of the Service Desk's most important responsibilities are monitoring incidents and communicating with users. Information security is considered an iterative process that must be controlled, planned, implemented, evaluated, and maintained.
It is a formal, written agreement that documents the levels of service, including information security, that IT is responsible for providing.
This can help an organization understand the effectiveness of its information security program and comply with regulatory requirements (for example, HIPAA or Sarbanes Oxley). It requires a number of best practices - such as Change Management, Configuration Management, and Incident Management - that can significantly improve information security. ITIL requires designing and building consistent, measurable information security measures into IT services rather than after-the-fact or after an incident. The reporting also allows management to make informed decisions about the risks their organization has. This can allow information security staff to communicate more effectively with internal and external business partners, such as an organization's outsourced security services. As an information security professional, however, you can add value by bringing ITIL to the attention of senior management. Depending on the size and complexity of an organization, implementing it can take significant up front time and effort. It is risky, expensive, and inefficient for organizations to have their information security depend on cobbled-together, homegrown processes.
Organizations thrive and gain competitive advantage using information technology by way of information systems and other electronic means. There are many ideas and thoughts of what makes a system secure, but the IT Security Management industry follows standards and guidelines to ensure consistency and effective means to securing critical systems.
One way to ensure you are up to date is with lifelong learning and a certificate in your area of expertise. Some of those rules are defined during the Service Design stage, for example to ensure that Events are triggered when the required service availability is endangered.
Since then, ITIL has become an entire industry of organizations, tools, consulting services, related frameworks, and publications. For example, a considerable number of information security issues are caused by inadequate change management, such as misconfigured servers.
ITIL can help managers understand that information security is a key part of having a successful, well-run organization.
For many organizations, successful implementation of ITIL will require changes in their organizational culture and the involvement and commitment of employees throughout the organization. ITIL can enable these processes to be replaced with standardized, integrated processes based on best practices.
Weil specializes in the areas of security policy development, HIPAA compliance, disaster recovery planning, security assessments, and information security management. A read of this book can tell you how PM will fit into an organization, and the types of conflict that can arise when line management and project management come together.
Currently in the public domain and still evolving, the 44-volume set of ITIL guidelines has been consolidated into 8 core books. Though some time and effort are required, ITIL can improve how organizations implement and manage information security. IT Security Management is the practice of protecting information systems from internal and external network attacks.
