Lifecycle governance in cybersecurity refers to the comprehensive management and oversight of digital identities, data, or assets throughout their entire lifespan. This process begins with the creation or onboarding of an identity or asset, continues through various stages of use and modification, and concludes with its deactivation or retirement. Effective lifecycle governance ensures that security policies and compliance requirements are enforced at every stage, minimizing the risk of unauthorized access, data breaches, or compliance violations. By systematically managing the lifecycle, organizations can close security gaps, reduce vulnerabilities, and maintain robust access controls, thereby protecting sensitive information and maintaining regulatory compliance.
