Cloud Security involves protecting data, applications, and services hosted in cloud environments from cyber threats. It includes encryption, identity and access management (IAM), security monitoring, and compliance enforcement. Cloud security ensures data integrity, prevents unauthorized access, and safeguards against cyberattacks like data breaches and malware. Organizations must implement robust security policies, multi-factor authentication, and regular audits to mitigate risks and ensure compliance with industry standards. With cloud adoption rising, strong security measures are crucial to maintaining trust and data protection.
