The core philosophy of ITIL revolves around the concept of providing IT services as a means to support business objectives. It emphasises the importance of understanding and meeting customer requirements, optimising service quality, and continually improving service delivery.

ITIL Information Security Management is a specific domain within the ITIL framework that focuses on ensuring the confidentiality, integrity, and availability of information assets within an organisation. With the increasing reliance on technology and the growing threat landscape, organisations need robust information security practices to protect sensitive data, prevent unauthorised access, and mitigate risks.

ITIL Information Security Management

Information Security Management is one of ITIL4’s 34 practices. Information Security Management provides organisations with a structured and systematic approach to identifying, assessing, and managing information security risks. It involves establishing policies, implementing controls, and conducting regular audits to ensure the confidentiality, integrity, and availability of information assets.

ITIL Information Security Management also plays a crucial role in regulatory compliance. Many industries have specific regulations and standards governing the protection of sensitive data, such as personally identifiable information (PII) or financial information. By following the ITIL framework, organisations can ensure they meet these regulatory requirements and avoid potential legal and financial repercussions.

The ultimate goal of ITIL Information Security Management is to protect sensitive information, maintain business continuity, and uphold the trust and confidence of customers and stakeholders. By implementing security controls, organisations can minimise the likelihood and impact of security incidents, such as data breaches or unauthorised access.

PeopleCert have recently released a course called ITIL® 4 Practitioner: Information Security Management. It is a one-day course that covers the practice in full.
