Final answer:
A cloud infrastructure improves security in an organization through centralized control and monitoring, automated backups and disaster recovery, and robust security measures provided by cloud providers.
Step-by-step explanation:
An organization's security is enhanced by a cloud infrastructure in a number of ways. Initially, it offers centralized data control and monitoring, which facilitates the identification and handling of security breaches. Second, it makes disaster recovery and routine automated backups possible, guaranteeing that data is safe and easily recoverable in the event of an incident. Last but not least, cloud providers frequently implement strong security measures, like multi-factor authentication and powerful encryption protocols, to help shield data from unwanted access.
