Information Security Management in ITIL

Updated: Mar 11


An image representing information security

Within the ITIL v4 framework, Information Security Management is not merely a defensive measure but a strategic asset that underpins information confidentiality, integrity and availability. Or, as we often refer to it in Info Sec circles, "The CIA".

  • Confidentiality - Is the data protected and restricted to the right people?

  • Integrity - Is the data unaltered and trustworthy? (i.e. it hasn't been damaged or changed)

  • Availability - Do the right people have it when and where they need it?

As cyber threats become increasingly sophisticated and pervasive, the role of Information Security Management transcends traditional boundaries, intertwining with every aspect of IT service delivery.  

The significance of Information Security Management cannot be overstated. It can open an organisation to opportunities others cannot access if handled well and destroy a reputation if mishandled. Companies can suddenly find themselves scrambling to up their Information Security game in a desperate bid to engage with clients (and suppliers) who will otherwise not engage.

ITIL v4's Information Security Management provides an agile and resilient framework, capable of adapting to new threats while supporting the organisation's overall strategic objectives. It's less about the technical controls and more about the governance and management framework around the controls.

As we delve deeper into the nuances of Information Security Management within the ITIL v4 framework, it becomes evident that this practice is not just about mitigating risks; it's about creating an environment where security is woven into the fabric of the organisation's IT processes, and the service lifecycle; through their design transition and support.

As someone once said, "Security isn't something you can add on at the end; it needs to be woven into the fabric of everything you do in building services from the outset."

Definition of Information Security Management in ITIL v4

Information Security Management (ISM) within the ITIL v4 framework is a practice designed to ensure the comprehensive protection of an organisation's information assets.

This practice is fundamental in safeguarding against the myriad threats that modern organisations face, ranging from cyber-attacks to data breaches and from internal vulnerabilities to external threats. ISM's core objective is to protect the confidentiality, integrity, and availability (CIA) of information, ensuring that data is accessible to authorised users when needed while being secure from unauthorised access or alterations.

It's important to understand, however, that ITIL, like other similar frameworks such as ISO 27001, is not prescriptive in terms of saying 'thou must...' in terms of the technologies and counter-measures used; it is far more about setting up a management system around security that enables the organisation to reflect upon its challenges and risks and determine what the appropriate responses should be.

The Essence of Information Security Management

At its heart, Information Security Management in ITIL v4 is about balancing protecting information and enabling business operations.


The word "Enabling" is crucial. Too many security experts would have a system so tightly restricted that it becomes a nightmare.

Good Information Security finds the balance and does not create barriers for the sake of barriers. It is not solely about implementing technical controls and security measures but also about aligning these measures with the business's strategic objectives. This alignment ensures that security processes do not hinder but enable the smooth operation of business processes, thereby adding value rather than being seen as an impediment.

Strategic Alignment and Comprehensive Protection

Information Security Management under ITIL v4 advocates for a holistic approach to security focusing on IT infrastructure and considering aspects such as employee awareness, process design, and even the physical security of information assets.

The practice is built upon the principle that security is everyone's responsibility, requiring a culture of awareness throughout the organisation. Therefore, you are building a culture as much as a process regarding Information Security.

Adapting to the Evolving Threat Landscape

A distinctive feature of Information Security Management in the ITIL v4 framework is its emphasis on adaptability and continual improvement.

In a digital landscape where threats evolve rapidly, ISM's flexible framework enables organisations to adapt their security measures swiftly. This adaptability is crucial for avoiding potential security threats and ensuring that information assets remain protected against current and future vulnerabilities.

Information Security is not a do-and-forget style process, it is iterative, on a constant cycle of planning, action, reflection, and adjustment. In this way, it is very closely linked to the practice of continuous improvement.

In a healthy organisation with mature ISM practices, documents are frequently reviewed, risk assessments are happening consistently, and an ongoing awareness and training programme is in place.

A Comprehensive Framework for Security

ITIL v4's Information Security Management framework encompasses several key components, including:

  • Information Security Policy: The backbone of ISM, outlining the organisation's approach to managing information security.

  • Risk Management: A systematic approach to identifying, assessing, and mitigating information security risks.

  • Security Controls: Measures implemented to protect information assets.

  • Incident Management: Processes for responding to and managing security incidents.

These are all common components of an Information Security Management System (ISMS) and the first things requested by any external audits by customers or external bodies when evaluating the maturity of an organisation.

Purpose and Value of Information Security Management

The Strategic Value of Information Security Management (ISM)

The value of ISM lies in its ability to intertwine security practices with business objectives, creating a secure foundation that supports and enables the achievement of these goals.

By embedding security considerations into the heart of organisational processes, ISM ensures that security is not seen as an afterthought but as an integral part of the organisation's strategy and operations.

Let's delve into these aspects to understand the comprehensive benefits ISM offers.

Information Security Benefits

Safeguarding Sensitive Information and Data Integrity

Earlier, we explored the CIA in information security, which forms the triad of confidentiality, integrity and availability. To explore each in a little more detail,


Confidentiality ensures that sensitive information is accessible only to those authorised to view it.

This component of the CIA triad is pivotal in preventing the unauthorised disclosure of information and safeguarding personal privacy, corporate secrets, and national security interests. Techniques to uphold confidentiality include data encryption, rigorous access controls, and the use of authentication mechanisms.

By implementing such measures, organisations can ensure their information remains confidential and accessible only to those with the requisite clearance or credentials.


Integrity involves maintaining the accuracy and reliability of data throughout its lifecycle. This means ensuring that information is not altered unauthorised, whether due to malicious intent or inadvertent errors.

Integrity safeguards against data tampering, ensuring that information remains uncorrupted and trustworthy.

Mechanisms to preserve integrity include checksums, digital signatures, and version controls. These tools help detect alterations and ensure that data can be restored to its original state, thus maintaining its trustworthiness and reliability.


Availability ensures that information and resources are accessible to authorised users when needed.

This aspect of the CIA triad addresses the need for reliable access to information systems and data, ensuring that business processes can continue unhindered.

Organisations implement redundant systems, perform regular maintenance, and develop disaster recovery plans to enhance availability. These measures are crucial for mitigating downtime risks and ensuring critical systems remain operational, even in the face of technical failures or cyber-attacks.

Mitigating Risks Related to Cyber Threats and Security Breaches

Proactive Threat Mitigation

ISM's risk management processes enable organisations to proactively identify potential security threats and implement measures to mitigate them before they can impact the business.

There's no magic process or tool to do this. Still, by being vigilant, reviewing the threat landscape, scanning for vulnerability and having a solid patching approach, an organisation can put itself on the front foot regarding threat mitigation.

Reduced Incident Impact

A well-prepared ISM framework ensures rapid response and mitigation when security incidents occur, minimising the impact on business operations and reputation.

It is recommended to leverage the standard incident and major incident management practices but also maintaining a 'break glass in case of emergency' cyber incident response plan. A response plan can help an organisation know what to do in the event of a breach, such as invoking insurance support, protecting the trail of evidence, or knowing whom to contact in certain circumstances.

Failing to plan is planning to fail...

Ensuring Compliance with Regulatory Requirements and Standards

Regulatory Adherence

Many industries face strict regulatory requirements regarding data protection and privacy. ISM helps ensure compliance with these regulations, avoiding legal penalties and financial losses.

An example might be ensuring that staff understand the implications of GDPR on the data they are handling or other laws such as HIPAA. Some legislation carries massive penalties if data is mishandled.

Standard Alignment

Adhering to established information security standards (such as ISO/IEC 27001) supports compliance efforts and enhances the organisation's security posture and credibility. Therefore, if the organisation wishes to achieve certification in ISO 27001, it would be a natural evolution.

Facilitating Trust and Confidence Among Stakeholders

Reputation Management

A robust ISM framework signals to customers, investors, and partners that the organisation protects information assets seriously. This commitment can significantly enhance the organisation's reputation and stakeholder confidence.

Equally, a lack of a verifiable ISM framework may hold an organisation back, as it is becoming increasingly common for organisations to undertake serious due diligence on each other's security position before entrusting data or integrating systems.

Some organisaitons walk an incredibly thin line with data security, wherein everyone knows full well that one slip-up would grab headlines and irreparably damage the organisation's credibility. Yet, they continue to hope for the best and roll the dice, which is no way to conduct mature business operations.

More and more frequently, it is becoming the cost of doing business, and rightly so.

Customer Loyalty

Maintaining an established trust in an organisation's ability to protect personal and sensitive data can be a decisive factor for customers, influencing their loyalty and the likelihood of repeat business.

It is much easier to stay with an organisation with proven data security practices than to move to an untrusted and unevaluated provider.

Enhancing Business Continuity and Resilience

By safeguarding against information security incidents that can disrupt business operations, ISM is crucial in ensuring business continuity.

In the old days, everyone needed off-site backup regimes and disaster recovery centres. Post-pandemic, many organisations have realised they can work effectively with modern technologies from distributed locations and that most technologies are cloud-hosted on AWS or Azure tech solutions. Hence, the need for disaster recovery and business continuity practices becomes one of the failover technologies and availability zones and less about protecting on-site backups. That said, ensuring you have evaluated the significant threats to your business operations and have continuity practices ready if needed is necessary for all.

Key Components of Information Security Management

The Information Security Management (ISM) practice within ITIL v4 encompasses several key components, each playing a vital role in the effective management and protection of information assets;

Information Security Policy

The Information Security Policy is the cornerstone document that outlines the organisation's approach to managing information security and the first document requested in an external audit. It sets the tone for security practices and establishes the framework for all security activities.

This policy includes guiding principles for security, defining roles and responsibilities, and setting out the expectations for behaviour regarding information security within the organisation.

You will typically have an overarching policy and sub-policies for specific areas, such as 'Bring Your Own Device Policy' or 'Acceptable Use'. This entirely depends upon the organisation.

In practice, you want the policy to be easy to read and comply with, so anything too legal and wordy is likely to satisfy the legal counsel but unlikely to get compliance from staff simply because the messaging is unclear.

Information Security Controls

Information Security Controls are the technical and administrative measures to protect information assets. These controls are based on the risk assessment and are designed to mitigate identified risks to an acceptable level.

Controls can be preventive, detective, or corrective, ranging from access controls and encryption to security monitoring and incident response mechanisms.

Various controls, including ISO 27001 Annex A, the 'Statement of Applicability', Cyber Essentials from the UK government, or the NIST control set, can be used. They are all similar in that they effectively comprise of a comprehensive list of security controls that an organisation should put in place and then record how they met the control.

Risk Management Framework

If there's a heart to Information Security, it's the Risk Management framework which provides a systematic approach to identifying, assessing, and managing information security risks.

It ensures that security measures are aligned with the organisation's risk appetite and business objectives.

Risk management is an ongoing process involving regular reviews and updates to reflect changes in the threat landscape or the business environment.

Risk Management & Mitigation Stages
Risk Management & Mitigation Stages

The risk management framework must have stages that provide an overall methodology for identifying, evaluating and managing risks. This would be accompanied by a risk log, which captures all the risks and provided as evidence in any external audit to show that the organisation understands the risk it faces, what it might accept, and what it is doing to mitigate or reduce those risks.

Security Incident Management

This component deals with the processes and procedures for managing information security incidents. Effective incident management minimises the impact of security breaches and restores normal operations as quickly as possible.

Key aspects include incident detection, response, recovery, and post-incident analysis to improve future resilience. The sooner an organisation can detect and address an event, the less damage will be done.

Below is a video about the Major Incident Process, which is a valid way of handling major security incidents from a process perspective but typically needs augmenting with a checklist for other activities such as contacting the authorities in case of a personal data breach in the UK or EU.

Security Awareness and Training

Security Awareness and Training aims to foster a security-conscious culture within the organisation. Educating employees about security policies, threats, and safe practices is crucial for reducing human-related vulnerabilities.

This component involves regular training sessions and awareness campaigns to keep security in employees' minds.

Security Governance

It's crucial to have a governance structure and clear roles & responsibilities (which we'll return to later). A central team or governance structure provides;

  • Strategic Oversight: Security Governance provides the strategic direction and oversight for the ISM practice. It ensures that information security is aligned with the organisation's goals and that sufficient resources are allocated to security initiatives.

  • Accountability and Improvement: Governance structures hold the organisation accountable for its security posture and promote continual improvement in security practices.

Sponsorship from the very top of the management tree is crucial, as is empowerment for the security team or group put in place. They should meet at least annually, but its is recommended that quarterly meetings are conducted to review strategy, scope, and escalated issues.

The Integrated Nature of ISM Components

The effectiveness of Information Security Management lies in the integrated operation of these components. Each plays a distinct role, yet they are interdependent, contributing to a holistic security strategy that protects information assets while supporting business objectives.

For instance, the effectiveness of Security Controls is greatly enhanced by a well-informed workforce through Security Awareness and Training. At the same time, the Risk Management Framework provides the necessary insights to tailor these controls effectively.

Moreover, the dynamic nature of the threat landscape and business environments demands that these components are not static.

Regular reviews, updates, and improvements are essential to ensure the ISM practice remains effective and aligned with the organisation's evolving needs and objectives.

Integration With Other ITIL Practices

Information Security Management (ISM) is not an isolated practice within the ITIL v4 framework; it intricately intertwines with several other ITIL practices, enhancing and being enhanced by them. This integration is critical for ensuring a holistic service management and security approach.

Let's explore how ISM supports and is supported by other ITIL practices.

Service Design

  • Security by Design: ISM is integrated into the Service Design practice to ensure security considerations are embedded from the earliest stages of service development. This approach helps identify security requirements and controls for new or changed services.

  • Risk Assessment: Part of the service design involves conducting risk assessments to identify specific security risks associated with new services, ensuring that appropriate mitigation strategies are in place before deployment.

Service Transition

  • Change Management: ISM is crucial during the Service Transition phase, particularly in Change Management. It ensures that any changes to services or the IT environment do not compromise information security, assessing risks and impacts of proposed changes.

  • Release and Deployment Management: Security controls and requirements are reviewed and tested as part of Release and Deployment Management to ensure that new or updated services maintain the organisation's security posture.

Service Operation

  • Incident and Problem Management: ISM is closely linked with Incident and Problem Management practices. Information security incidents are managed within the framework of ISM, while insights from these incidents inform ongoing security improvements and problem-resolution strategies.

  • Access Management: Access Management practices are supported by ISM policies and controls to ensure that access to information and services is appropriately controlled and monitored, aligning with the principles of least privilege and need-to-know.

Continual Improvement

  • Security Improvement: The Continual Improvement practice encompasses ISM by using feedback from security incident management, audits, and reviews to identify areas for improvement in security policies, controls, and processes.

  • Performance Measurement: ISM contributes to continuous improvement by using key performance indicators (KPIs) and metrics to measure the effectiveness of security measures, guiding strategic improvement initiatives.

Risk Management

  • Integrated Risk Management: ISM's risk management processes complement the broader organisational Risk Management practice. This integration ensures a consistent approach to identifying, assessing, and mitigating risks across all organisation areas, including information security.

Integrating ISM with these ITIL practices underscores the importance of a holistic and integrated approach to service management and information security. By embedding security considerations into every stage of the service lifecycle, organisations can ensure that their services are efficient, effective, and secure.

This synergy between ISM and other ITIL practices ensures that security is not seen as a standalone or after-the-fact consideration but is an integral part of the organisation's service management processes. It highlights the importance of collaboration between different teams and disciplines to achieve a secure, resilient, high-performing service environment.

Roles & Responsibilities within Information Security Management

In Information Security Management (ISM) within ITIL v4, delineating roles and responsibilities is crucial for effectively protecting information assets.

Key KPIs & Metrics for Information Security Management

In the Information Security Management (ISM) domain within ITIL v4, Key Performance Indicators (KPIs) and metrics are essential tools for measuring the effectiveness of information security practices. These metrics help assess the current security posture and guide strategic decisions and improvements in security processes.

The strategic application of these KPIs and metrics enables organisations to not just react to security incidents but to anticipate and prevent potential security breaches. By regularly monitoring these metrics, organisations can identify trends, uncover areas of weakness, and implement targeted improvements to enhance their information security posture.

Furthermore, these metrics provide valuable insights to senior management and stakeholders, demonstrating the effectiveness of the organisation's ISM practices and its value in protecting information assets. Regular reporting on these KPIs supports transparency and accountability, fostering a culture of continuous improvement in information security management.

These tools provide the technological backbone for detecting emerging threats, enforcing security policies, and ensuring compliance with regulatory requirements. By integrating these tools into their ISM strategy, organisations can achieve a more proactive and resilient security posture capable of responding to the dynamic threat landscape.

In addition to the tools mentioned, organisations should continually assess and adopt new technologies and solutions that align with their specific security needs and business objectives. Integrating these tools with existing ITIL practices ensures a comprehensive and cohesive approach to information security management, supporting the overall goal of protecting information assets while enabling business agility and growth.

Advice for Implementing and Enhancing Information Security Management Practices

In the pursuit of establishing robust Information Security Management (ISM) practices, organisations face numerous challenges. From evolving cyber threats to regulatory complexities, the path to adequate information security is fraught with obstacles. However, organisations can successfully navigate these challenges through the following advice;

  • Stay Current: The digital landscape continuously evolves, with new threats emerging rapidly. The owners should undertake regular security policy and procedure updates to ensure they remain relevant.

  • Create well-defined information security policies: Which are easily understandable for employees. Ensure that the language used is clear and concise.

  • Avoid Ambiguity: Be cautious with wording. Maintain consistency in word choices throughout the policy.

  • Balance Advice: Ensure that you provide actionable advice without overwhelming employees.

  • Prioritise: Focus on the most critical advice that employees should act upon.

Invest in Employee Training and Awareness Programs

  • Cultivate a Security-Conscious Culture: Employees are often the first line of defence against security threats. Investing in regular training and awareness programs is crucial to ensure they understand the risks and their role in mitigating them.

  • Behavioural Change: The goal is to foster a culture where security is everyone's responsibility, encouraging vigilant and responsible behaviour across all levels of the organisation.

  • Bottom-Up and Top-Down Approaches: Consider both bottom-up and top-down approaches for implementing information security. Bottom-Up: Involve employees at all levels. Encourage them to report security incidents and contribute to security awareness. Top-Down: Leadership commitment is crucial. Executives should set the tone, allocate resources, and prioritise security initiatives.

  • Accountability and Roles: Prioritise and define roles and responsibilities related to information security.

  • Assign Ownership: Designate individuals responsible for specific security tasks.

  • Training and Awareness: Ensure employees understand their roles and receive relevant training.
