Access certification is a process in which organizations review user access to their systems and data to ensure that it meets security, compliance, and governance standards. This type of certification involves periodic reviews of user accounts and privileges, as well as granting or revoking access when necessary. During the review process, organizations will verify that users have appropriate levels of access based on their roles within the company and ensure that they only have access to the resources they need to perform their duties. Access Certification can help an organization maintain visibility into who has what level of access, providing an added layer of security against malicious actors trying to gain control of sensitive information or assets.
