Cloud security involves protecting data, applications, and services hosted in cloud environments from cyber threats. It encompasses a variety of measures including encryption, identity and access management (IAM), network security, and compliance with regulatory standards such as GDPR and HIPAA. Cloud security helps businesses secure their cloud infrastructure and applications against breaches, data loss, and unauthorized access while ensuring high availability and resilience. By using advanced tools and technologies such as firewalls, multi-factor authentication, and intrusion detection systems, businesses can safeguard sensitive data in cloud environments. Cloud security also ensures that companies maintain compliance with industry standards, mitigate risks, and enable secure cloud adoption across various platforms, including public, private, and hybrid clouds.
