ITIL (Information Technology Infrastructure Library) is a set of best practices for IT service management that can improve information security. ITIL defines processes for configuration management, incident and problem management, change management, and more. It takes a process-based approach to security that incorporates policies, processes, procedures, and work instructions into a continuous cycle. Implementing ITIL can help organizations develop structured and aligned security, establish accountability through SLAs and auditing, and communicate security's value to business stakeholders. While requiring resources, adopting the ITIL framework can ultimately save time and money for organizations through more efficient security management.
