Enhanced security protocols, such as encryption, multi-factor authentication, and firewall implementations, protect cloud data by providing multiple layers of defense against unauthorized access and data breaches. Encryption secures data in transit and at rest, rendering it unreadable to attackers. Multi-factor authentication adds an extra verification step for users trying to access sensitive information. Firewalls monitor and control incoming and outgoing traffic, preventing malicious attacks. Together, these measures ensure the confidentiality, integrity, and availability of cloud-stored data.
