Challenges in protecting data in a cloud environment include issues related to data security, compliance, and accessibility. Because data is stored off-site and accessed via the Internet, it is vulnerable to cyber attacks, hacking, and accidental exposure. Organizations must adhere to strict regulations such as GDPR or HIPAA, complicating their compliance efforts. Moreover, reliance on third-party cloud providers raises concerns about their security measures and data management practices. Implementing robust security protocols, encryption, and regular audits is essential to protect sensitive information and maintain trust with customers.
