To secure cloud-based applications, several technologies are employed, including encryption, which protects data at rest and in transit, and identity and access management (IAM), which governs user permissions and authentication. Additionally, firewalls help block unauthorized access, while intrusion detection systems monitor for suspicious activities. Security information and event management (SIEM) tools analyze security alerts in real-time. Multi-factor authentication (MFA) strengthens access control, ensuring only authorized users can reach sensitive applications. These technologies collectively protect cloud resources from threats and vulnerabilities.
