Cloud computing has become an indispensable tool in today's digital environment, offering flexibility and scalability in the use of computing resources. However, alongside its numerous advantages, various security challenges such as unauthorized access, data breaches, and attacks on infrastructure have emerged. Utilizing models like IaaS, PaaS, and SaaS, as well as different deployment types, requires active involvement from both users and service providers in maintaining security. The implementation of protection mechanisms such as encryption, authentication, and the principle of least privilege, along with continuous education and awareness of potential threats, is crucial for the secure use of cloud services. In conclusion, effective data protection in the cloud requires comprehensive and proactive security strategies that involve continuous risk assessment and monitoring. Through ongoing threat monitoring, adaptation of security measures, and alignment with security standards, users and organizations can achieve a high level of data protection. This enables the full utilization of cloud computing advantages, ensuring a reliable environment for data storage and processing.
